Through the heat exchanger, heat is exchanged with the external environment to achieve efficient operation of the heat pump system.

[0003] In Chinese patent publication number CN220507388U, an air source heat pump defrosting device is disclosed to solve the problem that the scraping structure is easily worn and thus does not contact the frost surface sufficiently, thereby reducing the defrosting effect of the scraping structure. The device comprises a heat pump group, wherein an exhaust fan is arranged on the top of the heat pump group; guide blocks are arranged on the front and rear sides of the heat pump group; a transmission block is slidably mounted on the guide block; a transmission plate is arranged at the bottom of the transmission block; a spring A is arranged between the inner side of the transmission block and the inner side of the guide block; a driving motor is arranged at the bottom of the front side of the heat pump group; a guide screw is arranged on the driving motor; support members are arranged on the left and right sides of the top of the heat pump group; and a defrosting frame is slidably mounted on the heat pump group.

[0030] The working principle and beneficial effects of the above scheme:

[0031] The present application sets a reciprocating assembly between the drive motor 7 and the defrost shovel 5, so that the defrost shovel 5 reciprocates to shovel frost on the fin surface while the drive motor 7 maintains stable rotation. This solves the problem in the prior art that the drive motor direction needs to be changed during the defrosting process, making it impossible for the drive motor to rotate continuously and stably, that is, it is impossible to defrost continuously and stably, resulting in low efficiency.

[0032] Example 2

[0033] See also Figure 1 On the basis of Example 1, it also includes a temperature sensor 3 and a relative humidity sensor 4, wherein the temperature sensor 3 and the relative humidity sensor 4 are arranged on the surface of the fin 2, and the temperature sensor 3 and the relative humidity sensor 4 are connected to the defrost assembly.

[0034] The working principle and beneficial effects of the above scheme:

[0035] The present application uses the temperature sensor 3 and the relative humidity sensor 4 arranged on the fin 2 to turn on the circuit of the defrost component when it detects that the environmental conditions of the fin 2 are within the set limits, and the defrost component performs defrosting operation, rather than using the defrost component to operate all the time to defrost, thereby avoiding the problem of high energy consumption and non-energy saving and environmental protection caused by the defrost component operating all the time.

[0036] The technology of conducting the circuit of the temperature sensor 3 and the relative humidity sensor 4 can refer to the Chinese patent CN213024012U, a wireless antifreeze control system for an orchard.

[0037] Example 3

[0038] See also Figure 1 On the basis of Embodiment 1-2, a heat pipe 1 runs through the fin 2 .

[0039] The fins 2 are provided in several groups.

[0040] The working principle and beneficial effects of the above scheme:

[0041] The arrangement of the heat pipe 1 penetrating and plugging into the fin 2 helps to increase the heat exchange area and improve the heat exchange efficiency.

[0042] Example 4

[0043] See also Figure 1-4 On the basis of Embodiments 1-3, the defrost shovel 5 is arranged between two adjacent groups of fins 2.

[0044] The defrost assembly includes a defrost drill bit 6 , which is rotatably connected to the defrost shovel 5 , and a distal end of the defrost drill bit 6 is located outside the defrost shovel 5 .

[0045] The reciprocating assembly includes a roller 10 , the output end of the driving motor 7 is connected to one end of the roller 10 , and the other end of the roller 10 is connected to a defrosting drill 6 .

[0046] The roller 10 is provided with a chute 16, and the chute 16 is provided with two groups. The rotation directions of the two groups of chute 16 on the roller 10 are opposite, and the two groups of chute 16 are connected at both ends of the roller 10. The two groups of chute 16 are cross-arranged on the roller 10;

[0047] A reciprocating slider 11 is slidably connected in the slide groove 16 , and the reciprocating slider 11 is rotatably connected to a connecting sleeve 12 . The connecting sleeve 12 is sleeved on the outer periphery of the rotating roller 10 , and a defrosting shovel 5 is fixedly connected to the connecting sleeve 12 .

[0048] The working principle and beneficial effects of the above scheme:

[0049] The driving motor 7 arranged on one side of the fin 2 drives the roller 10 to rotate, and because the defrost shovel 5 is slidably connected to the fin 2, the defrost shovel 5 is fixed to the connecting sleeve 12, and the connecting sleeve 12 is rotatably connected to the reciprocating slider 11, the reciprocating slider 11 moves along the axial direction of the roller 10 relative to the roller 10 when sliding in the slide groove 16, thereby driving the defrost shovel 5 to move along the axial direction of the roller 10, that is, the defrost shovel 5 moves on the fin 2, so that the frost formed between the fins 2 is separated from the fin 2 under the movement of the defrost shovel 5, and the defrosting operation is completed. At the same time, under the effect of the rotation of the roller 10, the defrost drill 6 rotates on the adjacent fins 2 to break up the frost between the adjacent fins 2, which is beneficial to the defrosting operation of the defrost shovel 5;

[0050] When the reciprocating slider 11 moves to the two ends of the roller 10 in the slide groove 16 , the rotation direction of the slide groove 16 changes, and the reciprocating slider 11 moves in the opposite direction and repeats the movement afterwards, which is beneficial to enhance the defrosting effect.

[0051] Example 5

[0052] See also Figure 1-3 On the basis of Embodiment 1-3, a reducer 9 is arranged between the output end of the driving motor 7 and the rotating roller 10.

[0055] The inner gear ring sleeve 15 is fixedly connected to the rotating roller 10 .

[0056] The working principle and beneficial effects of the above scheme:

[0057] By setting a reducer 9 between the output end of the driving motor 7 and the roller 10, the moving speed of the defrost shovel 5 is slowed down, and the power of the defrost shovel 5 and the defrost drill 6 is increased, which is beneficial to enhancing the defrosting effect of the defrost shovel 5 and the defrost drill 6.
