[0052] The power supply module 144 can be configured to provide power to the signal source and the power amplifier 143.

[0053] In particular, the refrigeration system can further include a heat dissipation pipeline 127. The heat dissipation pipeline 127 can be configured to communicate with a throttling element at one end and communicate with the compressor 120 or an evaporator at the other end, and at least exchange heat with a part of the heating unit, so as to dissipate heat from the heating device of the heating unit by using the low-temperature refrigerant flowing out of the throttling element, and reduce the required layout space of the heating device and the production cost.

[0054] The heat dissipation pipeline 127 can be configured to exchange heat with at least the power amplifier 143, so as to increase the continuous working time of the electromagnetic wave generating system and ensure the heating effect.

[0055] The technical solutions of the present application will be described below with reference to the case that the heat dissipation pipeline 127 only exchanges heat with the power amplifier 143, and the storage compartment includes a freezing compartment 111 and a refrigerating compartment 112.

[0056] Figure 3 is a schematic structural diagram of a refrigeration system according to an embodiment of the present application. Referring to Figure 2 and Figure 3 In some embodiments, the refrigeration system can include a compressor 120, a condenser 121, a condenser heat dissipation fan 122, a freezing capillary 123, a freezing evaporator 124, and a freezing circulation fan 125.

[0059] The refrigeration system can be configured to start or continue the operation of the compressor 120 when the electromagnetic wave generating system is in the working state, and make the first on-off element 128 communicate the throttling element and the heat dissipation pipeline 127 to dissipate heat from the power amplifier 143.

The power module 144, the signal source, and the power amplifier 143 can be arranged outside the thermal insulation layer of the cabinet 110 and at or above the top of the cabinet 110 to reduce the impact on the temperature of the storage compartment.

[0067] The pipe connecting the second on-off element 129 and the compressor 120 can be arranged outside the thermal insulation layer of the cabinet 110 to exchange heat with the ambient environment of the cabinet 110 for heat dissipation, thereby reducing the temperature of the refrigerant entering the compressor 120 and reducing the load of the compressor 120.

[0068] In the present embodiment, the refrigeration system can only include one evaporator (i.e., the freezing evaporator 124) and deliver cold energy to the refrigeration compartment 112 through a duct or the like. The refrigeration system can further include a refrigeration evaporator arranged at the rear side of the refrigeration compartment 112 to separately cool the refrigeration compartment 112.

[0069] Figure 4 is a schematic structural diagram of a refrigeration system according to another embodiment of the present application. Referring to Figure 4 In some further embodiments, the refrigeration system can further comprise a second on-off element 129.

[0070] The heat dissipation pipeline 127 can be configured to directly connect to the refrigeration pipeline 126 at one end, so that the refrigerant flowing out of the freezing capillary 123 flows to the refrigeration evaporator 124 at the same time, and flows to the heat dissipation pipeline 127.

[0071] The refrigeration system can be configured to start or continue the operation of the compressor 120 and to communicate the condenser 121 with the freezing capillary 123 by the electromagnetic valve 132 when the electromagnetic wave generating system is in the working state, so as to dissipate heat from the power amplifier 143.

[0072] In some further embodiments, the refrigeration system can further comprise a second on-off element 129. The second on-off element 129 can be configured to selectively communicate the heat dissipation pipeline 127 with the compressor 120, or the heat dissipation pipeline 127 with the refrigeration evaporator 134, so as to defrost the refrigeration evaporator 134 as needed.

[0073] The refrigeration system can be configured to communicate the heat dissipation pipeline 127 with the refrigeration evaporator 134 downstream of the second on-off element 129 to defrost the refrigeration evaporator 134 by using the waste heat generated by the power amplifier 143 when the refrigeration evaporator 134 meets the defrosting condition.

[0074] The refrigeration system can be configured to communicate the heat dissipation pipeline 127 with the compressor 120 by the second on-off element 129 to avoid the undesired temperature rise of the refrigeration compartment 112 when the refrigeration evaporator 134 downstream of the second on-off element 129 does not meet the defrosting condition.

[0076] The heat dissipation pipeline 127 can be directly connected in series between the refrigeration capillary tube 123 and the refrigeration pipeline 126. The refrigeration system can be configured to start or continue to operate the compressor 120 and make the electromagnetic valve 132 connect the condenser 121 and the refrigeration capillary tube 123 to dissipate heat for the power amplifier 143 when the electromagnetic wave generating system is in the working state.

[0077] In some further embodiments, the refrigeration system can further comprise a second on-off element 129. The second on-off element 129 can be configured to selectively connect the heat dissipation pipeline 127 and the refrigeration evaporator 124 or the heat dissipation pipeline 127 and the refrigeration evaporator 134.

[0078] The refrigeration system can be configured to connect the heat dissipation pipeline 127 and the refrigeration evaporator 134 through the second on-off element 129 to avoid the refrigeration compartment 111 from being undesirably heated when the electromagnetic wave generating system is in the working state, and connect the heat dissipation pipeline 127 and the refrigeration evaporator 124 when the electromagnetic wave generating system is in the non-working state.

[0079] Referring to Figure 1 and Figure 2 In some embodiments, the top wall of the cabinet 110 can be formed with a downwardly recessed accommodating cavity, and the power supply module 144 and the power amplifier 143 can be at least partially arranged in the accommodating cavity.

[0080] A cover plate can be arranged on the cabinet 110 to cover the power supply module 144 and the power amplifier 143. The cover plate can be provided with a ventilation opening to allow the power supply module 144 and the power amplifier 143 to exchange heat with the ambient environment naturally.

[0081] The heat dissipation pipeline 127 can be wound around the outer periphery of the power amplifier 143 to increase the heat exchange area between the heat dissipation pipeline 127 and the power amplifier 143.

[0082] The heat dissipation pipeline 127 can further be in contact with the power amplifier 143 through a structure such as heat paste or heat conductive metal sheet to further improve the heat exchange efficiency between the heat dissipation pipeline 127 and the power amplifier 143.
