Where is the refrigeration sheet of the electronic refrigeration of the water dispenser?

The refrigeration sheet is between the aluminum sheets on the outer wall of the refrigeration lake in the water dispenser.

Refrigeration sheets are also called thermoelectric semiconductor refrigeration components, Peltier and so on. Because the refrigeration sheet is divided into two sides, one side absorbs heat and the other side dissipates heat, which only plays a role in heat conduction and does not produce cold itself, so it is also called a refrigeration sheet, or it should be called a refrigeration sheet.

As a special cold source, semiconductor refrigeration sheet has the following advantages and characteristics in technical application:

1. It does not need any refrigerant, it can work continuously, there is no pollution source, there are no rotating parts, there is no rotation effect, there is no sliding part is a solid sheet piece, there is no vibration, noise, long life and easy installation when working.

2. The semiconductor refrigeration sheet has two functions, which can not only refrigerate but also heat, and the refrigeration efficiency is generally not high, but the heating efficiency is very high, which is always greater than 1. Therefore, a single piece can be used instead of a separate heating and cooling system.

3. The semiconductor refrigeration sheet is a current transducer type piece, through the control of the input current, it can achieve high-precision temperature control, coupled with temperature detection and control means, it is easy to realize remote control, program control, computer control, and is convenient for the formation of an automatic control system.

4. The thermal inertia of the semiconductor refrigeration sheet is very small, the refrigeration and heating time is very fast, and the refrigeration sheet can reach the maximum temperature difference in less than one minute when the hot end heat dissipation is good and the cold end is no-load.

5. The reverse use of semiconductor refrigeration sheet is temperature difference power generation, and semiconductor refrigeration sheet is generally suitable for power generation in medium and low temperature areas.

6. The power of a single refrigeration element pair of semiconductor refrigeration sheet is very small, but when it is combined into a stack, and the power can be very large if it is combined into a refrigeration system by combining the same type of stack series and parallel connection method, so the refrigeration power can be in the range of a few milliwatts to tens of thousands of watts.

7. The temperature difference range of semiconductor refrigeration sheet can be realized from positive temperature 90 to negative temperature 130.

Cooling part - cold tank - refrigeration sheet (behind the cold faucet).

You're talking about the evaporator, which is wrapped in the back of the water dispenser.

Now the water dispenser is basically a refrigeration and heating machine, even if there is no heating, there is only refrigeration, the water dispenser is every family, but the principle is not necessarily known to everyone, so for the common water dispenser in life, we still know the refrigeration principle is better, but the drinking water mechanism is divided into two kinds, the following is one of the ones I introduced to you, the working principle of the refrigeration sheet, let's take a look!

It is a kind of semiconductor refrigeration sheet (TE), also known as thermoelectric refrigeration sheet, which is a kind of heat pump. It can be used for cooling or heating, which can be achieved by changing its wiring. When an n-type semiconductor material and a p-type semiconductor material are combined to form a galvanic couple, after the DC current is turned on in this circuit, the energy can be turned off and disconnected, and the current flows from the n-type element to the connector of the p-type element to absorb the heat, and becomes the cold end refrigeration; The heat is released from the P-type element to the connector of the N-type element, which becomes the hot end heating.

The installation and use of the refrigeration sheet is simple. Before installation, it is best to prepare a little thermal grease, and then, find a dry battery, connected to the two leads of the refrigerator, you can feel that one end is obviously cold and the other end is hot, remember the polarity of the lead and determine the cold and hot end of the refrigerator.

During the formal installation, evenly coat the thermal grease at both ends of the cooler, insert the cooling sheet between the CPU and the radiator, pay attention to the direction of the hot and cold surfaces that have been tried first, the cold side is attached to the CPU, and the hot side is in contact with the strong (the higher the power, the better) heat sink. Then the idea is fixed on the three. Be careful that the clip of the fan is not too short, otherwise it will be difficult to fix.

If the power supply of your case is less than 230W, I advise you not to connect it to the power supply of the case, otherwise it may be due to insufficient power supply, causing the computer to not work normally.

Although it is a small water dispenser, it still contains a lot of things that we don't know, if we are not professional design inventors, we should also know a thing or two about it, so that we will be more assured to use the water dispenser, so that our life is more delicate, and the health of the whole family is our happiness.

Drinking machines are usually cooled in two ways:

Compressed refrigerated water dispenser: The cooling principle of compressed refrigerated drinking water dispenser is that after pressing the refrigeration switch of the compressed refrigerated water dispenser, the compressor in the water dispenser will automatically start, suck back the refrigerant that has been heat absorbed and vaporized in the evaporator, and then compress it into a high-temperature and high-pressure gas sent to the condenser, and then dissipate heat and condense into a high-pressure liquid into the outside air through the condenser, and then be throttled and depressurized into the evaporator after passing through the capillaries of the water dispenser, absorbing the heat of the cold tank for cooling.

Thermoelectric refrigeration, also known as thermoelectric refrigeration or semiconductor refrigeration, is a refrigeration method that uses the thermoelectric effect. At present, the semiconductor material bismuth antimonide is used to make n-type and p-type thermocouples, and the semiconductor refrigeration device is composed by the module method. n-type materials have excess electrons and have a negative temperature difference potential.

P-type materials have insufficient electrons and positive temperature difference potential; When an electron crosses a junction from a p-type to an n-type, its energy must increase, and the increased energy is equivalent to the energy expended by the node. Conversely, when electrons flow from n-type to p-type material, the temperature of the junction increases.

In contrast, compressor refrigeration is more efficient and effective, and hot spot refrigeration is only suitable for home or office use with a small number of users, and the energy consumption is worse than compressor refrigeration.

The air compressor knows a lot.

The comrades upstairs play big, the landlord, you will know the heat pipe technology when you look it up on the Internet, in fact, it is achieved by using the difference between the temperature of the dry bulb and the wet bulb, and the car refrigerator on the car uses such technology. There is no compressor
