[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0034] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0035] like Figures 1-3 As shown, this invention provides a high-efficiency heat dissipation type variable frequency air source heat pump, including: an air source heat pump body 100, wherein the air source heat pump body 100 is a device that operates on the principle of compression cycle. It consists of four main components: a condenser 3, an evaporator, a compressor, and an expansion valve.

[0036] Firstly, the evaporator absorbs heat from the air to evaporate the low-temperature and low-pressure refrigerant, thereby absorbing the heat energy in the air. Then, the refrigerant enters the compressor, and the temperature and pressure of the refrigerant are increased by compression. Next, the high-temperature and high-pressure refrigerant enters the condenser 3, and releases heat by contacting the cooling medium in the warm air system or hot water system, so that the refrigerant is cooled and becomes a liquid. Finally, the refrigerant enters the expansion valve, and the pressure is reduced under the action of the expansion valve, and then the temperature is reduced, and then the refrigerant enters the evaporator again, and circulates repeatedly.

[0037] In order to achieve high heat dissipation of the air source heat pump body 100, a fan body 2 is installed in the heat pump case 1 of the air source heat pump body 100, and a frequency conversion drive board 4 is configured for the compressor, an air inlet grille 11 is installed on the right side wall of the heat pump case 1, the condenser 3 is L-shaped and close to the inner wall of the heat pump case 1, the fan body 2 is located in front of the condenser 3, and the frequency conversion drive board 4 is located in front of the right side of the condenser 3 and close to the air inlet grille 11, so that when the air source heat pump body 100 operates, the cooling air flow of the frequency conversion drive board 4 is discharged from the outside through the air inlet grille 11, the flow guide cover 5 and the fan 1. The cooling air flow is smooth and does not pass through the condenser 3 and is not heated, so the temperature of the cooling air is much lower than that of the traditional heat pump, the cooling temperature difference is large, the cooling effect is better, and the high heat dissipation of the air source heat pump body 100 is achieved.

[0038] As shown in Figure 2 Further, in some embodiments of the present application, a drive board flow guide cover 40 is also installed on the frequency conversion drive board 4, and a radiator 41 is installed on the front side of the frequency conversion drive board 4, so that when the heat is dissipated, the heat generated by the frequency conversion drive board 4 is dissipated outward through the drive board flow guide cover 40, and the cooling air flow passes through the drive board flow guide cover 40 to take away the heat of the frequency conversion drive board 4, and the radiator 41 is also conducive to heat dissipation, so that the frequency conversion drive board 4 can work better.

[0039] As shown in Figure 2 Further, in some embodiments of the present application, a middle partition plate set 12 is also configured in the heat pump case 1, the middle partition plate set 12 includes a first middle partition plate body 121 and a second middle partition plate body 122, the first middle partition plate body 121 is installed between the front side wall of the heat pump case 1 and the left end of the frequency conversion drive board 4, and the second middle partition plate body 122 is installed between the right end of the condenser 3 and the left end of the frequency conversion drive board 4. The above-mentioned middle partition plate set 12 divides the heat pump case 1, so that the heat pump case 1 can be installed conveniently and has larger installation space, which is more friendly to the design of the radiator 41; and further makes the cooling air flow smooth: the overall air flow path is smooth, the air flow path can cover each position of the radiator, the contact is sufficient, and the heat exchange effect is good.

[0040] Further, a fan shroud 21 is installed in the heat pump cabinet 1, and the fan shroud 21 is located at the front side of the fan body 2. Therefore, when the heat pump cabinet 1 is cooling, the air flow is discharged outward through the fan shroud 21, thereby improving the cooling efficiency.

[0051] As shown in Figure 7 , Figure 9 , further, the inner locking member 74 is installed in the second anti-loosening cylinder 72 in some embodiments of the present application, and two inner locking rods 621 are installed in the first anti-loosening cylinder 62, and the two inner locking rods 621 are located on both sides of the inner guide seat 63, wherein two first locking holes 721 are formed in the end of the second anti-loosening cylinder 72, and the inner locking rods 621 can be inserted into the first locking holes 721 and connected with the inner locking member 74, so that the inner locking member 74 is used to internally fix and lock the inner locking rods 621, thereby realizing the fixation between the first anti-loosening cylinder 62 and the second anti-loosening cylinder 72.

[0052] Further, the inner locking piece 74 comprises an inner square frame 741, two T-shaped rods 742, and an inner elastic block 743.
