In order to ensure the reliability of the drive itself, the compressor frequency can only be unloaded, reducing the refrigeration capacity of the unit and affecting the refrigeration ability of the unit. Traditional frequency converters adopt the drive air-cooled heat dissipation method, but the heat dissipation effect of this heat dissipation method is not very good, resulting in a narrow application ambient temperature.

[0034] Embodiment 1

[0035] This embodiment provides a heat dissipation structure driven by a new type of frequency conversion controller. As shown in the attached Figure 1-2 figure, it is installed in the housing 100. The housing 100 is provided with a first chamber 101 for accommodating the fan 11 and a second chamber 102 for accommodating the frequency conversion controller 12. A partition 103 is provided between the first chamber 101 and the second chamber 102. In this embodiment, the first chamber 101 and the second chamber 102 are arranged up and down, and the partition 103 is located therebetween. Here, the partition 103 is specifically a sheet metal part. In addition, it should be noted that the frequency conversion controller 12 controls the operation of the refrigerator.

[0036] The heat dissipation structure includes:

[0037] An air duct 13, which is connected to the frequency conversion controller 12. Here, the air duct 13 is specifically attached to the outer wall of the frequency conversion controller 12 to form a connection and fixation effect. One end of the air duct 13 communicates with the second chamber 102, and the other end of the air duct 13 passes through the partition 103 and communicates with the first chamber 101, and the air duct 13 forms a communication effect between the first chamber 101 and the second chamber 102.

[0038] A fan 14, which cooperates with the air duct 13. During the operation of the fan 14, air is transmitted to the air duct 13 to accelerate the flow rate of the air duct 13 and improve the heat dissipation effect.

[0039] A liquid cooling component 15, which cooperates with the air duct 13. The liquid cooling component 15 includes a refrigerant, and a certain cooling effect is achieved through the refrigerant to improve the heat dissipation effect.

[0040] In the normal state, the air duct 13 dissipates heat, and a negative pressure is formed by the operation of the fan 11 to achieve the heat dissipation effect of the air duct 13.

[0041] At the first temperature, the air duct 13 and the fan 14 cooperate for heat dissipation. At this time, only relying on the air duct 13 for heat dissipation cannot achieve rapid cooling. By cooperating with the fan 14, the flow rate inside the air duct 13 is increased, and the heat dissipation effect is improved.

[0042] At the second temperature, the air duct 13, the fan 14, and the liquid cooling component 15 cooperate for heat dissipation. The refrigerant forms a cooling effect, and then the fan 14 and the air duct 13 cooperate to transfer the hot air to the first chamber 101.

[0043] The second temperature > the first temperature > the normal state. Here, the second temperature and the first temperature can be a threshold value, that is, set as an interval; or they can be a fixed value. For example, the second temperature is 90°C and the first temperature is 80°C. The setting of the air duct 13 forms an interaction between the first chamber 101 and the second chamber 102. During operation, the fan 11 works, causing positive and negative pressures to be generated between the first chamber 101 and the second chamber 102. The heat of the second chamber 102 can enter the first chamber 101 through the air duct 13, and interactive heat dissipation is formed through the fan 11. Secondly, combined cooling can also be carried out through the fan 14; when the application environment temperature is higher, liquid cooling, the fan 14, and the air duct 13 can be combined to form a heat dissipation and cooling effect. The above three modes ensure that the driving temperature is within a suitable range through optimizing the structure and control, and broaden the application environment temperature of the entire unit.

[0044] Specifically, as shown in the appendix Figure 1-2 As shown, the air duct 13 includes a first channel 131 and a second channel 132. The first channel 131 and the second channel 132 are vertically connected, and the first channel 131 and the second channel 132 cooperate to form an inverted L-shaped structure. The partition 103 is provided with a through hole 1031, and the second channel 132 is connected to the through hole 1031. The combined setting of the first air duct 13 and the second air duct 13 serves to increase the length of the air duct 13, buffer the impact of heat on the fan 11, so that the heat generated by the frequency conversion controller 12 can be slowly neutralized and discharged. Secondly, the air duct 13 also serves as a space for giving way to avoid the installation and fixation of other components. In addition, the air duct 13 can also directly go upward to vertically penetrate the partition 103 to form an up-and-down connection effect.

[0045] Specifically, as shown in the appendix Figure 1-2 As shown, the first channel 131 is connected to the outer wall of the frequency conversion controller 12, and the second channel 132 is connected to the partition 103. The distribution of the first channel 131 and the second channel 132 is fixed, improving the fixing strength of the entire air duct 13 and preventing breakage. In this embodiment, the first channel 131 and the second channel 132 can be integrally formed or independently arranged.

[0046] Specifically, as shown in the appendix Figure 1-2As shown, the first channel 131 is provided with a first extension 1311. A screw passes through the first extension 1311 and is connected to the outer wall of the variable frequency controller 12. The number of screws fixed here can be adjusted according to actual needs. The second channel 132 is provided with a second extension 1321. A screw passes through the second extension 1321 and is connected to the partition 103. The number of screws fixed here can be adjusted according to actual needs. By using the screw fixing method, the fixing strength is improved. In addition, the fixing method between the air duct 13 and the variable frequency controller 12 and the partition 103 can also adopt pasting, welding or other methods.

[0047] Specifically, as shown in the appendix Figure 1-2 As shown, the area where the first channel 131 cooperates with the outer wall of the variable frequency controller 12 can be adjusted according to actual needs.

[0048] Specifically, as shown in the appendix Figure 1-2 As shown, the fan 14 cooperates with the first channel 131. The fan 14 is fixedly connected to the first channel 131. During the operation of the fan 14, the flow rate in the air duct 13 will be accelerated, so that the heat generated by the variable frequency controller 12 can be taken out to the first chamber 101 by air cooling. In this embodiment, the size, size, quantity and power of the fan 14 can be adjusted according to actual needs.

[0049] Specifically, as shown in the appendix Figure 1-2 As shown, the liquid cooling component 15 includes a liquid cooling pipe 151. One end of the liquid cooling pipe 151 extends into the first channel 131, and the other end of the liquid cooling pipe 151 extends from the first channel 131 to the second chamber 102. It should be noted here that the liquid cooling pipe 151 does not pass through the through hole 1031 and extend into the first chamber 101. Here, the liquid cooling pipe 151 is located in the first channel 131, and the liquid cooling pipe 151 is attached to the outer wall of the variable frequency controller 12 to form a cooling effect. The liquid cooling pipe 151 forms a cooling and heat dissipation effect through laying. The laying method of the liquid cooling pipe 151 in the first channel 131 here can be adjusted according to actual needs. The liquid cooling pipe 151 can only be filled with refrigerant to achieve a cooling effect, which is common knowledge.

[0050] Specifically, the liquid cooling component 15 further includes a solenoid valve 152, and the solenoid valve 152 controls the flow of the refrigerant. The solenoid valve 152 performs a control effect to control opening and closing. In this embodiment, the solenoid valve 152 is located at the input end of the liquid cooling pipe 151 to control whether the refrigerant enters the liquid cooling pipe 151. It should also be noted that the circulation system of the liquid cooling component 15 has nothing to do with this embodiment, and those skilled in the art should also know how the refrigerant forms a cycle, so it is not shown in the drawings.

[0051] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of the creation of the present utility model.
