[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

Each connector has a cover with a connection port on its side away from the heat exchanger body. A heat dissipation box is fixedly connected to the top of the heat exchanger body.

A heat dissipation assembly is provided inside the heat dissipation cavity. The heat dissipation assembly includes a threaded rod rotatably connected to the heat dissipation cavity, a T-shaped block threadedly connected to the threaded rod, and symmetrical holes formed on the T-shaped block. A cooling fan is fixedly installed in each hole. A heat dissipation hole is formed on the top of the heat dissipation box and communicates with the heat dissipation cavity.

The slider is threadedly connected to the bidirectional lead screw, and the slider extends into the adjustment groove and is fixedly connected to the adjustment block.

[0010] Furthermore, to facilitate the rotation of the bidirectional lead screw, one end of the bidirectional lead screw extends outside the side box and is connected to the output end of the regulating motor.

[0011] Furthermore, in order to make the adjustment plate slide stably within the heat dissipation hole, an L-shaped groove is provided on the other end of the inner surface of the heat dissipation hole, and an L-shaped block is fixedly connected to the outer surface of the adjustment plate, with the L-shaped block slidably connected to the L-shaped groove.

Temperature sensor 27 is electrically connected to an external power supply and can be optionally equipped with a controller for automatic control. The detection end of temperature sensor 27 is located in the evaporation section of the heat exchanger body 1. Reciprocating motor 12 works, driving threaded rod 7 to rotate in heat dissipation cavity 5 and causing T-block 8 to slide back and forth in heat dissipation cavity 5. The sliding of T-block 8 causes cooling fan 11 to slide accordingly. The sliding of cooling fan 11 can dissipate heat evenly on the heat exchanger. By symmetrically arranging cooling fan 11 on T-block 8, the heat dissipation effect and efficiency of cooling fan 11 can be effectively improved, further improving the heat dissipation efficiency of heat exchanger.

[0032] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5Side grooves 14 are formed on both ends of the outer surface of the heat sink 4, and the side grooves 14 communicate with the heat dissipation holes 13. Adjusting plates 15 are slidably connected in the side grooves 14. To increase the sealing between the adjusting plates 15, sealing protrusions 16 are fixedly connected to the adjusting plates 15. A sealing groove 17 is formed on the other adjusting plate 15, and the sealing groove 17 is adapted to the sealing protrusion 16. An adjusting groove 18 is formed on one end of the inner surface of the heat dissipation hole 13. An adjusting block 19 is slidably connected in the adjusting groove 18. One end of the adjusting block 19 is fixedly connected to the adjusting plate 15, and the other end of the adjusting block 19 is connected to the adjusting assembly. The adjusting assembly includes a side box 20 fixedly connected to the outside of the heat sink 4. A side cavity 21 is formed inside the side box 20. A bidirectional lead screw 22 is rotatably connected in the side cavity 21. Slider blocks 23 are symmetrically arranged on the bidirectional lead screw 22.

The adjusting motor 24 is electrically connected to an external power supply and can be equipped with a controller for automatic control. In order to make the adjusting plate 15 slide stably in the heat dissipation hole 13, an L-shaped groove 25 is opened on the other end of the inner surface of the heat dissipation hole 13. An L-shaped block 26 is fixedly connected to the outer surface of the adjusting plate 15. The L-shaped block 26 is slidably connected to the L-shaped groove 25. When the adjusting motor 24 works, the adjusting motor 24 drives the bidirectional lead screw 22 to rotate in the side cavity 21 and makes the two sliders 23 slide in opposite directions.

[0034] In practical applications, the connector 2 is connected to an external device, and then the power supply is turned on for use. During use, the temperature sensor 27 is activated to monitor the temperature of the heat exchanger body 1. When the temperature is too high, the regulating motor 24 is activated according to the temperature value. The regulating motor 24 drives the bidirectional lead screw 22 to rotate in the side cavity 21 and causes the two sliders 23 to slide in opposite directions. The sliding of the sliders 23 can drive the regulating block 19 to slide synchronously. The sliding of the regulating block 19 can cause the two regulating plates 15 to slide in opposite directions. The sliding of the regulating plates 15 can adjust the heat dissipation hole 13 to the required size. Then the reciprocating motor 12 is activated. The reciprocating motor 12 drives the threaded rod 7 to rotate in the heat dissipation cavity 5 and causes the T-shaped block 8 to slide back and forth in the heat dissipation cavity 5. The sliding of the T-shaped block 8 causes the cooling fan 11 to slide accordingly. The sliding of the cooling fan 11 can dissipate heat evenly to the heat exchanger.
