The thermoelectric refrigeration module is a core component of the semiconductor refrigeration device, and the installation process of the thermoelectric refrigeration module has important significance for the efficient and stable operation of the semiconductor refrigeration device.
The semiconductor refrigerating sheet is formed by P, N semiconductor particles, copper guide bars and ceramic substrates which are arranged in an alternate array, the brittleness of the ceramic substrates is relatively large, the thickness of the ceramic substrates is only 1mm, the ceramic substrates are easy to crack once the problem of uneven stress occurs in the process of attaching and assembling the semiconductor refrigerating sheet with a radiator and a refrigerating block, and the traditional thermoelectric module mounting process is easy to cause damage to key parts.
As shown in fig. 3, 4 and 5, the mounting positions of the screws are equal to each other from two sides of the edge of the TEC (semiconductor refrigerator), and the screw holes reserved on two sides should be perpendicular to the cold and hot surfaces of the TEC and parallel to each other. If tilted, or one side screw is too tight, as shown in fig. 4 below, one side of the TEC does not fit against the heat generating electronics or heat sink, rendering it less than optimal and even causing damage to the TEC product. The TEC should be installed in the middle of the installation position to preset a uniform pre-compression force perpendicular to the refrigerating plate, and then the bolts on the two sides are fixed to avoid the occurrence of the situation.
In order to solve the problem that elements are damaged because bolts on two sides cannot be fixed simultaneously in the installation process of a thermoelectric refrigeration module, the application provides thermoelectric refrigeration module installation equipment, which comprises a clamping module 1, a transmission module 2, a tray module 3, a control panel 4, a box tray 5, a lifting module 8 and a base 6, wherein the lifting module 8 is arranged on the base 6, the box tray 5 is arranged on the lifting module 8, the transmission module 2 is arranged on the base 6, the tray module 3 and the clamping module 1 are arranged on the transmission module 2, the tray module 3 is arranged at one end, close to the box tray 5, of the transmission module 2, the clamping module 1 comprises a compression cylinder 11 and a compression rod 12, the compression rod 12 is arranged above the tray module 3, and the control panel 4 is electrically connected with the clamping module 1, the transmission module 2, the tray module 3 and the lifting module 8;

in response to the second instruction sent by the control panel 4, the lifting module 8 moves downwards until the upper half part of the refrigerating block passes through the box body and the box body tray 5 is separated from the box body;
In response to a fourth command sent by the control panel 4, the lifting module 8 moves upwards until the cooling block is out of contact with the tray module 3.
The refrigerating blocks are placed on the refrigerating block tray 32, and after a first instruction is sent through the control panel 4, the transmission module 2 drives the clamping module 1, the tray module 3 and the refrigerating blocks coated with the heat-conducting interface materials placed on the tray module 3 to move in the direction away from the box body tray 5. After a second instruction is sent through the control panel 4, the clamping module 1, the tray module 3 and the cooling block coated with the heat-conducting interface material placed on the tray module 3 move towards the direction close to the box tray 5, and then the transmission module 2 drives the clamping module 1, the tray module 3 and the cooling block coated with the heat-conducting interface material placed on the tray module 3 to move towards the direction close to the box tray 5, and after the box tray 5 is controlled to descend, the upper half section of the cooling block passes through the box.
After placing the cooling fin and the heat sink on the cooling block, the clamping module 1 compresses the cooling block, the cooling fin and the heat sink. After the bolts on the two sides are screwed, a fourth instruction is sent, the lifting module 8 moves upwards until the cooling block is separated from contact with the tray module 3, and then the clamping module and the tray module move in the direction away from the box body tray; at this time, the case having the thermoelectric refrigeration module mounted thereon can be taken off from the case tray 5.
In some embodiments, the transmission module 2 includes a guide rail frame 21, a servo motor 22, and a transmission mechanism 23, the guide rail frame 21 is disposed on the base 6, the transmission mechanism 23 is disposed on the guide rail frame 21, the servo motor 22 is connected with the transmission mechanism 23, and the tray module 3 and the clamping module 1 are disposed on the transmission mechanism 23.
When the transmission module 2 is started, both the tray module 3 and the clamping module 1 connected to the transmission module 2 move together with the transmission module 2.
In some embodiments, the tray module 3 includes a bottom plate 31 and a cooling block tray 32, the bottom plate 31 is disposed between the cooling block tray 32 and the transmission mechanism 23, and a groove is disposed on the cooling block tray 32, and the shape of the groove is matched with the shape of the bottom of the cooling block.
The grooves provided on the cooling block tray 32 may help to secure the cooling blocks placed on the tray module 3. Only when the clamping module 1 is lowered, the cooling block on the tray module 3 is exactly contacted, if the cooling block is accurately placed in the designed position.
In some embodiments, the refrigeration block tray 32 is provided with heating wires.
The traditional installation process of the thermoelectric refrigeration module adopts a manual mode to smear heat conduction silicone grease on a heat conduction interface, and then the radiator, the semiconductor refrigeration piece and the refrigeration block are fixed together by bolts.
The heat conduction interface material is of the types of heat conduction glue, heat conduction silicone grease, heat conduction gaskets and the like, and the heat conduction coefficient of the common heat conduction interface material is in the range of 2-5W/mK and is larger than the heat conduction coefficient of air by 0.0267W/mK, but is still very small compared with the heat conduction coefficient of an aluminum alloy radiator and a refrigerating block by 200-230W/mK, so that under the condition of ensuring that an air gap of a heat conduction interface is fully filled, the thinner and better the heat conduction interface material is, and the traditional process of manually smearing the heat conduction silicone grease is not easy to ensure the penetration effect of the heat conduction interface material and control the thickness of a coating.
The heat conduction silicone grease is the most common heat conduction interface material in the thermoelectric refrigeration module, the diluent of the heat conduction silicone grease is silicone oil, the filler is filled with alumina, magnesia, aluminum nitride and other micro powder particles, the diluent is characterized by good fluidity, the interface air gap is easy to fill effectively, the disadvantage is that the heat conduction coefficient is not high, the heat conduction interface material is easy to overflow, and once a 'heat bridge' is formed at the hot end and the cold end of the semiconductor refrigeration sheet, the refrigeration performance of the product is greatly reduced; the filler has the characteristics of high heat conductivity, poor fluidity and high difficulty in filling an air gap, so that the proportion of the base material and the filler in the heat-conducting silicone grease is very critical, and the requirement on the installation process of the thermoelectric refrigeration module is high.
The radiator and the refrigerating block are coated with heat-conducting interface materials, and when the heating wire is heated during installation, the temperature rise is favorable for improving the fluidity and permeability of the heat-conducting interface materials. The heat-conducting interface material comprises silicone grease and heat-conducting gel.
In some embodiments, the cold block tray 32 is provided with an induction coil configured to heat a cold block placed on the cold block tray 32 by a high frequency induction magnetic field upon energization.
Because the refrigerating block is made of metal, the upper part of the induction coil is prevented from generating heat due to electromagnetic induction, and the heat conduction interface material is heated after the heat generation, so that the fluidity and the permeability of the heat conduction interface material are improved.
In some embodiments, the base plate 31 is provided with a vibration motor 7, and the vibration motor 7 is configured to stop after vibrating for three seconds in response to the third instruction.
Under the actions of pressing force, vibration force and heating, the heat conduction interface material flows and fills fully on the contact surface, the thickness is further reduced, and the interface thermal resistance is ensured to be minimized.
