Fig. 4 is a schematic structural diagram of a first embodiment of a heat dissipating assembly of a display device according to the present utility model.

Referring to fig. 2 to 4, an evaporation pan 300 is disposed in the press bin 130, the evaporation pan 300 is used for receiving condensed water in the refrigerating compartment 110, a drain pipe is disposed at the bottom of the refrigerating compartment 110, and the lower end of the drain pipe is located above the evaporation pan 300 so as to drain liquid water in the refrigerating compartment 110 into the evaporation pan 300 through the drain pipe.

In some embodiments, a heater for defrosting the evaporator 240 is further provided in the refrigerator, and the evaporating dish 300 is capable of receiving defrosting water formed by defrosting the evaporator 240.

A fan 400 is disposed in the press bin 130 to drive air in the press bin 130 to flow, thereby improving air convection between the press bin 130 and the external environment and improving heat dissipation efficiency of the compressor 210 and the condenser 220 in the press bin 130.

A heat dissipating assembly 500 is further disposed in the press bin 130, and the heat dissipating assembly 500 includes a water conduit 510, a water pump 520 disposed in the water conduit 510, and an evaporator 530. The evaporation piece 530 is positioned above the evaporation pan 300, the inlet end of the water guide pipe 510 extends into the evaporation pan 300, and the outlet end is positioned above the evaporation piece 530 for guiding water in the evaporation pan 300 to the upper end of the evaporation pan 300; the water in the water guide pipe 510 drops onto the evaporation member 530, absorbs heat to evaporate on the evaporation member 530, and the water is changed into water vapor on the evaporation member 530. The evaporation member 530 evaporates to absorb heat, so that the evaporation member 530 is used to absorb heat of the condenser 220, and heat dissipation effect of the condenser 220 is improved.

The fan 400 is disposed toward the evaporation member 530 for circulating air around the evaporation member 530, thereby enhancing evaporation efficiency of water on the evaporation member 530.

In this embodiment, the vertical projection of the condenser 220 is located in the evaporation pan 300, and the evaporation member 530 is a fin structure disposed at the periphery of the condenser 220.

The water in the evaporation pan 300 is transported through the water guide tube 510 and drops over the fin structure, and the water on the fin structure slides down the fin structure into the evaporation pan 300. The water on the fin structure absorbs heat on the fin structure for absorbing heat released by the condenser 220. And the water on the fin structure can absorb heat and change phase into water vapor, and the water vapor is discharged outside the press bin 130 under the action of the fan 400.

Part of the water absorbs heat on the fin structure and then changes into vapor, and the vapor is blown out of the press bin 130 under the action of the fan 400, so that the heat is released out of the refrigerator. Some of the water on the fin structure, after absorbing heat, drops down from the water curtain paper into the evaporation pan 300 and is redirected to the fin structure by the water guide tube 510. Heat is absorbed through continuous evaporation of water and released outside the refrigerator, so that heat in the refrigerator is released outside the refrigerator.

In this embodiment, the outer periphery of the fin structure is coated with a hydrophilic coating, so that in the process that water flows from the fin structure slide down to the evaporating dish 300, more water flows are adsorbed on the fin structure, and more water flows are contacted with air, so that more water flows absorb heat on the fin structure, and therefore better heat absorption and heat dissipation effects are achieved.

The heat dissipation assembly 500 further includes a water inlet pipe 540, one end of the water inlet pipe 540 is connected to an external water source, and the other end of the water inlet pipe 540 is connected to the upper end of the water guide pipe 510, so that the external water source can be introduced into the water guide pipe 510. An external water source enters the water conduit 510 through the water inlet pipe 540 and is discharged from the outlet end of the water conduit 510 onto the fin structure to absorb heat of the fin structure.

When the water in the evaporation pan 300 for heat dissipation and evaporation is insufficient, an external water source is introduced into the water guide pipe 510 through the water inlet pipe 540, and after the external water source is discharged onto the fin structure, the external water source drops into the evaporation pan 300 from the fin structure, and the water guide pipe 510 introduces the water in the evaporation pan 300 to the upper side of the fin structure to form the circulation heat dissipation of the water.

In this embodiment, the heat dissipation assembly 500 further includes a water level sensor 550 for detecting the water level in the evaporation pan 300, and an electromagnetic valve 560 disposed on the water inlet pipe 540; the water level sensor 550 is electrically connected to the solenoid valve 560 to control the external water source to enter the water guide tube 510 for replenishing the evaporation pan 300 with water when the water level in the evaporation pan 300 is lower than a preset water level, and the battery valve is opened.

When the water level sensor 550 detects that the water level in the evaporation pan 300 is greater than the preset water level while supplementing water into the evaporation pan 300 through the external water source, the solenoid valve 560 is controlled to be closed, and the supplementing of water into the evaporation pan 300 is stopped, thereby avoiding the overflow of water in the evaporation pan 300. The preset water level is higher than the preset water level.

It should be noted that, in the present application, the refrigerator further includes a temperature sensor for detecting an external environment temperature, and the temperature sensor is electrically connected to the water pump 520, so that when the environment temperature and the set temperature of the refrigeration compartment 110 reach a preset heat exchange ratio, the water pump 520 is started, so that water in the evaporating dish 300 is introduced above the evaporating part 530.
