Self-made semiconductor refrigerator

Self-made semiconductor refrigerator, refrigerator is a common electrical appliance, and the temperature inside the refrigerator is very important. Many people will make some small refrigerators at home to ensure the quality of food. So, how to make your own refrigerator? Look at the homemade semiconductor refrigerator with me.

Self-made semiconductor refrigerator 1 first, you have to open a hole in your box, the size of which is similar to the water cooling head you use.

Then start to make a refrigeration device, and apply thermal paste (refrigeration piece, water cooling head, and thermal block) so as to conduct heat. After the refrigeration device is completed, it can be fixed with glue.

Then put the device in a foam box. After installation, the faucet should be outside, with the radiator in the middle and the radiator inside.

It's almost like this after the water pipe is installed. And it is connected to a water pump, which circulates water, and when the water flows through the water cooling head, it will cool the heat sink.

Then prepare the power supply for the refrigerator and water pump. Here's the thing, 120 watt.

A fan should be installed in the refrigerator to circulate the air in the refrigerator. The fan doesn't need to be big, as long as there is wind.

Connect the power supply and start running. The final test found that it can be reduced to 5.3 degrees.

Self-made semiconductor refrigerator 2 should first make a small hole in the prepared semiconductor refrigerator. Try to make the hole size match the size of the water cooling head we use. Then, you can start making refrigeration equipment. In fact, this refrigeration device is relatively simple, and the water cooling head, refrigeration sheet and heat conducting metal sheet can all be assembled.

When making refrigeration equipment, all parts must be coated with special thermal conductive paste sold in the market. Under the condition of ensuring the uniformity of thermal paste, the thermal paste should be as thin as possible. After the whole process is completed, the completed refrigeration device can be fixed with adhesive tape.

After the whole semiconductor refrigerator refrigeration device is installed, the water cooling head should be placed outside, the related refrigeration sheet should be placed between the water cooling head and the heat sink, and the metal sheet to help the whole device dissipate heat should be at the innermost. Then it is connected to the water pump in home life, so that the whole device can use water circulation, so that when cold water flows through the water cooling head, it will transfer cold air to the radiator to achieve the effect and purpose of cooling. In this way, your semiconductor refrigerator is a success.

Although DIY semiconductor refrigerator can't achieve the freezing effect, it is still very good for refrigeration or heat preservation. Now many enterprises, companies and families like to make a semiconductor refrigerator by themselves. The above is the simplest manufacturing process of semiconductor refrigerator. I hope you can have a deeper understanding of the performance and efficacy of this product.

Self-made semiconductor refrigerator 3 1. In terms of service life, the service life of constant speed air conditioner is much longer than that of variable frequency air conditioner; In terms of maintenance cost and difficulty, constant speed air conditioning is much better than variable frequency air conditioning.

2. At present, the design of frequency converters and the quality of parts in China are not mature, and the service life of fixed-frequency air conditioners is long, but the compressor capacitors and fan capacitors of fixed-frequency air conditioners are also broken.

3. There is no better problem between frequency conversion and fixed frequency, and each has its own advantages and disadvantages.

Many people have been brainwashed by the irresponsible propaganda of manufacturers. When it comes to inverter air conditioners, they will talk about saving electricity first. In fact, inverter air conditioner will save electricity than fixed frequency air conditioner only if it is turned on for a long time. If it is used for a short time (within 6 hours of continuous use), the power consumption is basically the same as that of fixed frequency. If you only use it for one or two hours at a time, the inverter air conditioner will consume electricity instead.

The biggest and only advantage of variable frequency air conditioner is that it can be used continuously for a long time, and its comfort exceeds that of fixed frequency air conditioner.

As for the advantages advertised by other manufacturers, such as low noise, of course, the inverter outdoor unit has low noise when it runs at low frequency. If the indoor unit is made of high-quality materials and the investment is increased, the noise will be as low as the high-grade frequency setter. There is also a low-voltage start. In fact, the low-voltage start of the frequency setter is equivalent to protecting the compressor in a disguised form. No matter what electrical appliance works under low voltage for a long time, it will have an impact on the life of this electrical appliance. The frequency converter can work at low voltage without affecting its service life. However, at low voltage, the inverter cannot achieve its due efficiency, which also affects the aforementioned comfort and destroys the only advantage of the inverter. Therefore, low-voltage start-up can only be said to be barely usable, not an advantage.
