Today we consider a number of designs of heaters for current cases of life. People need devices everywhere:
- in the cellar;
- in nature;
- in the aquarium;
- in the garage and in the country.
Consider how to make a heater with his own hand, from what elements. We thank the enthusiasts and professionals who posted on the forums and websites ingenious options for the design of heaters. It remains to analyze the ideas and summarize what they saw.
Oil heater for garage
If an old unnecessary car radiator is lying on the ground, it is simply excellent. Fit outboard with central heating, made of sheet iron. To make an oil heater with your own hands, you will need oil. Suitable technical, better - used purposefully for elevated temperatures. For example, to cool the engine. Look for transformer - this oil is designed for exposure to extreme factors.
Criteria! Oil tank does not reach 80 degrees Celsius. The average value is 60. When choosing an oil, look at the coefficient of thermal expansion.
Start with the frame. In the work we take a sealed radiator, it is easy to guess that the design weighs a lot. For the manufacture of an oil heater frame, corners will be useful for the construction of a frame mounted on wheels. It is difficult to offer a specific design, it is preferable to be suitable for transportation. Corners are sealed by welding.
At the bottom of the radiator, a pair of holes are made under the heating elements. You can borrow heating elements from old appliances or buy them on the market from merchants. The oil heater is supplied with a pump designed to pump working fluid through the heating elements. An electric motor will be required for actuation.
The number of heating elements in the oil heater is selected based on the required power of the device. The pump is installed without touching the heating elements. The jet stream is directed along the heating elements. Oil heater is fully sealed. Brewing joints, in extreme cases, sealed. Provide a screw cap for an emergency oil drain. Install a pressure relief valve. This will protect the radiator from damage.
heating elements are electrically connected in parallel, the maximum power of 230 V is taken. To regulate the temperature of the oil heater, complement the design with switches. After testing the product assembly, mount the radiator on the frame, and close the electric motor and the switch into the box. Do not forget about grounding: the garage is not a place where we should ignore the elementary safety rules.
The received device will not allow to freeze to the owner. Now consider how to make a heater for vegetables and other food, located in the cellar.
Frozen potatoes turn black and lose taste, just not stored. A small homemade heater will not freeze products.
The author of the invention recommends the use of the power from the voltage regulator on the KREN12A chip. The power transistor and a pair of resistors are tightly mounted on an aluminum sheet radiator. The point is to transfer the maximum heat to the metal. Installation of resistors is carried out on a special heat-conducting gel. Means, for example, lubricated contact area of processors in personal computers.
This is interesting! The BIOS recommends sounding the alarm when the threshold is exceeded 60 degrees Celsius. At 85, germanium microcircuits start to fail.
It is possible not to use the substrate made of PCB, making electrical connections with copper. Last for reliability, glue on the aluminum plate, a homemade heater is ready. Power is supplied by a voltage of 25 V DC.
According to the author, the transistor quickly heats up to 75 degrees Celsius. Heat and resistors, prudently mounted on a special gel. The temperature of the homemade heater reaches 50 degrees. If placed under the potato tray, the heat generated will be enough to prevent agricultural products from freezing.
When it’s cold at home, you can make a home-made heater from an old computer power supply. The cooler must be in good condition, in extreme cases, to create a home-made heater, replace the broken fan. Product idea: to replace the getinak printed circuit board with a non-foil PCB substrate, to which the straps are attached for winding a nichrome spiral.
The current heats the turns of the wire, the fan blows the structure with a warm current, the owner rejoices in the heat.
So let's get started. It is logical to start with the calculation of power and buy or cut the required amount of nichrome wire. For a home-made heater, it is better to provide for the presence of two separate spirals so that the temperature can be controlled.
For the frame textolite will go without foil, in which holes are drilled under the wire. Three strips are proposed to install in parallel. The layout of the holes in the homemade heater corresponds to the principle of presence. It is difficult to advise, it is easier to decide where and where to drill.
With the help of small metal corners, the slats are mounted on the substrate, parallel and at equal distance. Now we wind the spiral homemade heater. Do not touch the hull or parts of the structure in addition to the slats. To power the cooler, you will have to invent something like a rectifier from diodes, a capacitor and a small-sized transformer.
The spiral is directly connected directly to 220 V AC.The resulting device is added to the switches for the spirals and will begin to blow the host with warm air. Of course, the design burns oxygen, in addition, it will smell burnt. Created exclusively for unplanned cold.
Ceramic gas infrared heater portable type is expensive, in addition, fishermen dragging belongings on themselves. For carrying traditionally used iron box, which either roll on a sled, or hoisted on his back. Who wants to carry a gas cylinder for 27 liters in addition to the 1.5-kilogram heater.
Individual enthusiasts offer to make a tent heater with their own hands from a gas burner for cooking. The size together with the capacity is slightly larger than the Dichlorvos bottle. Naturally, you will take a small device with you when fishing.
The inventor proposes to use a strainer, a small piece of stainless steel mesh, steel plates for fasteners. The idea is in the principle of operation of bright gas infrared heaters. Gas burns, heats the grid, it radiates heat to the sides. The author shows that this design is much more efficient than the store burner for cooking when it comes to heating.
A cylindrical nozzle is assembled for the torch. The sidewall is curved from the mesh stainless steel section, the bottom and the roof are made of steel. Each round plate is supplied with four grippers at the edges. As a result, not a circle is cut from the sheet, but rather a gear with teeth.
Assembly design resembles a car filter in shape. In the bottom a hole is cut under the burner fire, a tea strainer is put upside down on curved teeth. It is possible that we will attach a similar strainer to the roof to increase the radiating surface, but the author, creating his own gas heater, did not do this.
How to attach the created "filter" to the burner, everyone decides for himself. It's time to eliminate the freezing of gas in the cylinder:
- Thick copper wire wrapped around the heated grid and the gas tank helps poorly. Maybe it will get better if you insulate it from above with a toe cap or with a fireproof FOAM.
- The author suggested using a copper bus instead of a wire. The thermal conductivity, of course, is much higher than the only core, it went smoothly. Tire - a strip of copper strip. One end is attached to the hot grid, the other to the balloon.
It is recommended to wrap a home-made heater with FOAM to save heat. To prevent the balloon from falling, look at a special stand in the store.
The author notes that the burners meet with a horizontal arrangement of the cylinder. In this case, the homemade heater does not fall, wrap a woolen sock so that the gas does not freeze in the cold.
Obviously, the device must be stocked with an additional balloon. In case the first is not enough. Do not interfere with the design and those who move by car.
It is enough to fill in the saline solution into the U-shaped tube, provide at both ends with stoppers with threaded carbon electrodes to get a homemade heater for the aquarium. Rapa conducts electrical current, simultaneously heating up and transferring heat to the walls of the flask. Power is selected by varying the salt concentration. Do not allow the level of the solution to go above the surface of the water.
