Background

Under the condition of high external temperature, an electric control module of the air conditioner outdoor unit generates heat and needs to be cooled in time. If the electronic control module has poor heat dissipation, the refrigerating capacity of the air conditioner can be seriously influenced.

However, the condensed water is directly introduced into the heat dissipation pipeline, and the temperature of the condensed water is too low, so that liquid drops are easily generated on the outer wall of the heat dissipation pipeline, and adverse effects are caused.

Referring to fig. 1 to 3, an outdoor unit of an air conditioner according to an embodiment of the present disclosure includes a casing 10, a heat exchanger 20, and a heat sink 30, where the heat exchanger 20 is in heat-conducting connection with a condensed water pipeline 40 of an indoor unit to exchange heat with condensed water in the condensed water pipeline 40; the radiator 30 is arranged in the casing 10, and the radiator 30 is used for heat dissipation and cooling of an electric control module of the air conditioner outdoor unit; the radiator 30 and the heat exchanger 20 are connected in series through a heat dissipation pipeline 302, the heat transfer medium in the heat dissipation pipeline 302 transfers the heat of the radiator 30 to the heat exchanger 20, the heat transfer medium exchanges heat with the condensed water in the condensed water pipeline 40 to cool, and the cooled heat transfer medium flows back to the radiator 30 to form a heat dissipation cycle.

By adopting the air conditioner outdoor unit provided by the embodiment of the disclosure, the heat of the electronic control module is transferred to the radiator 30 for heat dissipation and cooling, the heat transfer medium in the heat dissipation pipeline 302 is heated at the radiator 30 to change phase, and moves to the heat exchanger 20 to exchange heat with the heat exchanger 20 and the condensate water pipeline 40 flowing through the heat exchanger 20, and the cooled heat transfer medium flows to the radiator 30 along the heat dissipation pipeline 302 to perform the next heat dissipation cycle; in this way, the heat exchanger 20 is used as a heat exchange carrier for the condensate water pipeline 40 and the heat dissipation pipeline 302, so that adverse effects caused by the fact that the condensate water pipeline 40 directly flows into the heat dissipation pipeline 302 can be effectively avoided, in addition, the condensate water can be effectively utilized for heat dissipation and cooling, and the heat dissipation efficiency of the heat sink 30 on the electric control module of the air conditioner outdoor unit is improved.

The condensed water generated in the indoor unit partially or entirely flows into the condensed water pipe 40. In the pipe section where the condensed water pipeline 40 is in heat conduction connection with the heat exchanger 20, the condensed water exchanges heat with the heat exchanger 20, and the temperature of the heat exchanger 20 is reduced. When the heat transfer medium with a higher temperature in the heat dissipation pipeline 302 flows to the heat exchanger 20, the heat transfer medium can exchange heat with the heat exchanger 20, and is rapidly cooled to become the heat transfer medium with a lower temperature. Alternatively, the condensed water in the condensed water pipeline 40 exchanges heat with the heat transfer medium with higher temperature in the heat dissipation pipeline 302 at the heat exchanger 20 directly, so as to reduce the temperature of the heat transfer medium in the heat dissipation pipeline 302. Therefore, the condensed water in the condensed water pipeline 40 can directly exchange heat with the heat transfer medium in the heat dissipation pipeline 302, and the purpose of cooling the heat transfer medium in the heat dissipation pipeline 302 can also be indirectly achieved by using the heat exchanger 20 as an intermediate medium.

The heat dissipation pipeline 302 and the condensate pipeline 40 are not communicated with each other in the heat exchanger 20. The heat sink conduit 302 and the condensate conduit 40 may or may not be in direct thermally conductive contact.

Optionally, in a case that the heat dissipation pipeline 302 is in direct heat conduction contact with the condensed water pipeline 40, an outer wall of the heat dissipation pipeline 302 is attached to an outer wall of the condensed water pipeline 40 to directly exchange heat. Optionally, under the condition that the heat dissipation pipeline 302 is in direct heat conduction contact with the condensate pipeline 40, a part of the pipe section of the heat dissipation pipeline 302 may be embedded in the condensate pipeline 40, so that the condensate water in the condensate pipeline 40 directly flows through the outer wall of the heat dissipation pipeline 302 to exchange heat with the heat transfer medium, thereby further reducing the spacing distance between the condensate water and the heat transfer medium and improving the heat exchange efficiency of the condensate water and the heat transfer medium.

The radiator 30 and the heat exchanger 20 are connected in series through a radiating pipeline 302, and a heat transfer medium capable of transferring heat penetrates through the radiating pipeline 302. Wherein, the heat transfer medium can be water, refrigerant, antifreeze or phase-changeable heat transfer working medium. The heat transfer medium receives the heat emitted from the radiator 30, moves to the heat exchanger 20 along the heat radiation pipeline 302, exchanges heat with the heat exchanger 20 and the condensed water in the condensed water pipeline 40 flowing through the heat exchanger 20 in the heat exchanger 20, and the cooled heat transfer medium flows back to the radiator 30 along the heat radiation pipeline 302 to perform the next heat radiation circulation, so that the heat radiation efficiency of the radiator 30 is improved, and the electronic control module is rapidly cooled.

The heat sink 30 transfers heat through the heat transfer medium in the heat dissipation pipeline 302, so that the heat dissipation efficiency of the heat sink 30 is improved. The heat dissipation conduit 302 and the heat sink 30 may be considered as two separate components or as one integral component. Whether the heat dissipation pipeline 302 and the radiator 30 are two separate parts or one integrated part, the heat dissipation pipeline 302 is a closed circulation pipeline, so that the hidden danger of leakage at the joint of the heat transfer medium in the pipeline and the radiator 30 when the heat transfer medium flows through the radiator 30 can be eliminated.

Alternatively, the heat exchanger 20 is disposed on an outer side wall of the casing 10 to externally connect the condensate water line 40 to the outdoor unit of the air conditioner.

The heat exchanger 20 is arranged on the outer side wall of the casing 10, so that the heat exchanger 20 can be conveniently installed and connected with the condensate water pipeline 40, and unnecessary influence caused by the fact that the heat exchanger 20 occupies the space in the casing 10 can also be avoided.

In addition, the heat exchanger 20 is disposed outside the casing 10 by condensing the liquid droplets on the surface of the heat exchanger 20 after the condensed water pipe 40 passes through the heat exchanger 20, so that the liquid droplets on the surface of the heat exchanger 20 can be prevented from affecting some parts in the casing 10.

The heat exchanger 20 is detachably connected to the outer side wall of the casing 10 and is located at a side of the casing 10 near which the electronic control module is located. Thus, the distance between the radiator 30 and the heat exchanger 20 can be shortened, so that the length of the heat dissipation pipeline 302 is shortened, and the heat dissipation efficiency of the radiator 30 and the heat dissipation effect on the electronic control module are improved.

Alternatively, the condensate water line 40 is perforated in the heat exchanger 20, or the condensate water line 40 is wound outside the heat exchanger 20.

The condensate water pipeline 40 penetrates through the heat exchanger 20, and the heat exchanger 20 wraps the condensate water pipeline 40. Thus, the contact area between the condensate water pipeline 40 and the heat exchanger 20 is ensured, the heat transfer area between the condensate water pipeline 40 and the heat exchanger 20 is ensured, and the heat exchange efficiency between the condensate water pipeline 40 and the heat exchanger 20 is improved.

In the case where the condensate line 40 is inserted into the heat exchanger 20, the condensate line 40 may be inserted into the heat exchanger 20 in an S-shape. And heat-conducting glue can be smeared between the condensate pipeline 40 and the heat exchanger 20, so that on one hand, the firmness of connection between the condensate pipeline 40 and the heat exchanger 20 is ensured, and on the other hand, the heat exchange efficiency between the condensate pipeline 40 and the heat exchanger 20 is improved.

The condensate pipe 40 is wound around the outside of the heat exchanger 20, facilitating the installation and removal of the condensate pipe 40 from the heat exchanger 20. Wherein, twine under the outside condition of heat exchanger 20 at condensate water pipeline 40, can scribble the heat conduction glue between condensate water pipeline 40 and the heat exchanger 20, guarantee the firm in connection degree between condensate water pipeline 40 and the heat exchanger 20 on the one hand, on the other hand improves the heat exchange efficiency between the two.

The condensate water line 40 is inserted into the heat exchanger 20 or wound around the heat exchanger 20, and then communicates with the condensate water drain pipe 50 to discharge the condensate water having exchanged heat with the heat exchanger 20.

Optionally, the heat dissipation pipe 302 is disposed through the heat exchanger 20, or the heat dissipation pipe 302 is wound around the outside of the heat exchanger 20.

The heat dissipation pipeline 302 is disposed through the heat exchanger 20, and the heat exchanger 20 wraps the heat dissipation pipeline 302. Thus, the contact area between the heat dissipation pipeline 302 and the heat exchanger 20 is ensured, the heat transfer area between the heat dissipation pipeline 302 and the heat exchanger 20 is ensured, and the heat exchange efficiency between the heat dissipation pipeline 302 and the heat exchanger 20 is improved.

In the case where the heat dissipation pipe 302 is inserted through the heat exchanger 20, the heat dissipation pipe 302 may be inserted through the heat exchanger 20 in an S-shape. And heat-conducting glue can be smeared between the heat dissipation pipeline 302 and the heat exchanger 20, so that on one hand, the connection firmness between the heat dissipation pipeline 302 and the heat exchanger 20 is ensured, and on the other hand, the heat exchange efficiency between the heat dissipation pipeline 302 and the heat exchanger 20 is improved.

The heat dissipation pipe 302 is wound around the outside of the heat exchanger 20, and the heat dissipation pipe 302 and the heat exchanger 20 are easily mounted and dismounted. Wherein, under the outside condition of heat dissipation pipeline 302 winding in heat exchanger 20, can scribble the heat conduction glue between heat dissipation pipeline 302 and the heat exchanger 20, guarantee the firm in connection degree between heat dissipation pipeline 302 and the heat exchanger 20 on the one hand, on the other hand improves the heat exchange efficiency between the two.

In practical applications, the heat dissipation pipeline 302 and the condensed water pipeline 40 may be simultaneously installed in the heat exchanger 20, or simultaneously wound outside the heat exchanger 20, or the heat dissipation pipeline 302 is installed in the heat exchanger 20 and the condensed water pipeline 40 is wound outside the heat exchanger 20, or the heat dissipation pipeline 302 is wound outside the heat exchanger 20 and the condensed water pipeline 40 is installed in the heat exchanger 20. The specific connection structure between the heat dissipation pipeline 302 and the condensate pipeline 40 and the heat exchanger 20 can be determined according to actual conditions. For example, consideration may be given to heat exchange efficiency, assembly efficiency, cost, and the like.

Optionally, in the heat exchanger 20, the flow direction of the condensed water in the condensed water line 40 is opposite to the flow direction of the heat transfer medium in the heat dissipation line 302.

In the heat exchanger 20, the flow direction of the condensed water in the condensed water pipeline 40 is opposite to the flow direction of the heat transfer medium in the heat dissipation pipeline 302, so that a form of convection can be formed, the flow rate of the condensed water exchanging heat with the heat transfer medium is increased under the condition of a certain flow distance, the heat exchange efficiency between the heat transfer medium and the condensed water is improved, and the heat dissipation and cooling effects of the heat transfer medium in the heat dissipation pipeline 302 in the heat exchanger 20 are further improved.

Optionally, the condensed water pipeline 40 is in heat conduction contact with the air return pipeline 60 of the outdoor unit of the air conditioner, so that the condensed water in the condensed water pipeline 40 exchanges heat with the low-temperature refrigerant in the air return pipeline 60 to reduce the temperature of the condensed water.

In the cooling condition, the return line 60 communicates the indoor heat exchanger 20 and the compressor of the outdoor unit, and the low-temperature and low-pressure refrigerant flows through the return line 60, and the low-temperature and low-pressure refrigerant in the return line 60 flows from the indoor heat exchanger 20 to the compressor of the outdoor unit.

The condensed water pipe 40 is in heat-conductive contact with the return pipe 60 of the outdoor unit of the air conditioner before the heat exchanger 20 is heat-conductive connected, and the temperature of the condensed water in the condensed water pipe 40 can be further reduced by the low-temperature refrigerant in the return pipe 60. Particularly, when the air conditioner starts to perform a cooling operation, the indoor unit has no condensed water or has a small content of condensed water, and the lower temperature condensed water is helpful for reducing the temperature of the heat exchanger 20 and the heat transfer medium flowing through the heat dissipation pipeline 302 of the heat exchanger 20, so as to ensure the heat dissipation efficiency of the heat sink 30 and the heat dissipation effect of the electronic control module.

Optionally, the heat dissipation pipe 302 is provided with a pump body 303 to drive the flow of the heat transfer medium in the heat dissipation pipe 302.

The pump body 303 can accelerate the circulation flow of the heat transfer medium in the heat dissipation pipeline 302, so that the time of heat dissipation circulation of the heat transfer medium in the heat dissipation pipeline 302 is shortened, and the heat dissipation effect of the electronic control module is further improved.

In particular, when the heat medium in the heat radiation pipe 302 cannot naturally circulate by using advantageous conditions such as gravity, the pump 303 can contribute to the circulation of the heat medium. It can be seen that, by providing the pump body 303 on the heat dissipation pipeline 302, the limitation of the location of the heat dissipation pipeline 302 between the heat sink 30 and the heat exchanger 20 can be overcome, and the heat dissipation pipeline 302 can be provided as required.

Optionally, a heat dissipation pipe 302 extends through the casing 10 and is connected to the heat exchanger 20. The heat exchanger 20 is attached to the outer wall of the casing 10, and therefore the pump 303 is arranged in the casing 10, so that interference between the pump 303 and the casing 10 can be avoided, the length of the heat dissipation pipeline 302 exposed out of the casing 10 can be shortened, and leakage of heat transfer media caused by damage can be avoided.

The heat sink 301 has a certain thickness, which can facilitate the heat dissipation pipe 302 to be disposed inside the heat sink 301 or to be embedded in the surface of the heat sink 301. In addition, as much contact area as possible between the heat sink 301 and the heat dissipation pipe 302 is ensured, thereby improving heat transfer efficiency between the heat sink 301 and the heat dissipation pipe 302.

The heat sink 301 has a sheet structure, which not only facilitates laying of the heat sink pipeline 302, but also facilitates installation with the electronic control module.

It should be noted that "the heat dissipation pipeline 302 is wound around the outside of the heat dissipation fin 301" may be understood that the heat dissipation pipeline 302 is sleeved around the outside of the heat dissipation fin 301, or the heat dissipation pipeline 302 is only attached to a part of the surface of the heat dissipation fin 301. In practical application, the heat sink 301 is connected to the electronic control module in a heat conducting manner, and the connection surface between the heat sink 301 and the electronic control module is flat, which facilitates heat transfer between the heat sink 301 and the electronic control module.

Under the condition that the heat dissipation pipeline 302 is arranged inside the heat dissipation fin 301, the path for transferring heat from the electronic control module to the heat dissipation pipeline 302 is facilitated to be shortened, so that the heat circulation efficiency of the heat transfer medium in the heat dissipation pipeline 302 is improved, and the heat dissipation effect of the electronic control module is further improved.

In the case that the heat dissipation pipe 302 is embedded on the surface of the heat sink 301, on one hand, the heat dissipation pipe 302 is facilitated to be fixed, on the other hand, the contact area between the heat dissipation pipe 302 and the heat sink 301 can be enlarged, and the heat transfer area between the heat dissipation pipe 302 and the heat sink 301 is increased, so that the heat transfer efficiency between the heat dissipation pipe 302 and the heat sink 301 is increased.
