The refrigeration film is also called thermoelectric semiconductor refrigeration component, Parrad, etc.Because the refrigeration film is divided into two sides, one side absorbs heat, and the other is heat dissipation, it only plays a thermal conductivity. It will not cause cold, so it is also called a cold film, or it should be called a refrigeration film.
Refrigement manufacturer
Chongqing Chongqing Chongqing Refrigeration Equipment Factory is the earliest professional company engaged in freezing equipment design, manufacturing, sales, and installation in the Southwest.The equipment processing plant is the first company in the Southwest frozen industry to pass the ISO international quality system certification. It has a national tertiary electromechanical design and installation qualification.The headquarters of Shenzhen Beauty Platern Semiconductor Co., Ltd. is located in Longgang District, Shenzhen, and is specialized in high -tech enterprises specializing in semiconductor thermoelectric materials, semiconductor refrigeration films, and refrigeration components.Established in 2013, the company was founded by several returnee elites and marketing experts.The company serves customers with technological innovation and rapid response. The first quality policy is our quality policy. The factory has an annual production capacity of 10,000kg of semiconductor crystal rods, 2 million chips, and 100,000 sets of refrigeration components.60%of products are exported, including Europe, the United States, Canada, Australia, Japan and South Korea, and other Southeast Asian countries and regions.
Refrigeration film power
The power of the general refrigeration film refers to the power consumption, not the refrigeration. The refrigeration efficiency of the current refrigeration film is generally about 60%, that is, the energy efficiency ratio is about 0.6, which is very low (the heat pump of the compressor is at least 2.0 or more)EssenceTake 100 watts as an example: 100 watts of refrigeration tablets generally produce a cooling capacity of about 60 watts (can absorb the calories of about 60 Jiaoer from the cold surface per second), and the heat generated by the heat surface is very large.In addition to the heat generated by 100 watts of power consumption, there are about 60 watts of heat from about 160 watts of heat absorbed from the cold surface. The temperature of the hot and cold surface is very different.
How to use the refrigerator
1. The correct installation and assembly method of refrigeration film: 1. Install the heat sink while the refrigeration film is installed on the one side, and the surface plane of the installation surface is not greater than 0.03mm.2. The refrigeration tablets are in good contact with the cooling piece and the cold block.3. When fixing the refrigeration tablet, the refrigeration film should be uniform, but also pay attention not to excessive excessiveness to prevent porcelain slices from fracture.Second, the correct use conditions for refrigeration films: 1. The voltage of the DC power supply must not exceed the rated voltage, and the power ripple coefficient is less than 10%.2. The current must not exceed the rated current of the component.3. The refrigeration film must not be instantaneous when working (after 5 minutes).4. Inside the refrigeration film must not enter the water.5. The humidity around the refrigerator must not exceed 80%.
Refrigement principle
After connecting the DC power supply, the electrons depart from the negative electrode (-). First of all, pass the P-type semiconductor. Here we absorb the calories. When the N-type semiconductor is reached, the heat is released.On the other hand, the temperature difference is caused to form a hot and cold end.
