Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The main solution of the embodiment of the invention is as follows: the heat dissipation device comprises a first heat exchange pipeline and a second heat exchange pipeline communicated with the first heat exchange pipeline, wherein the first heat exchange pipeline is in heat conduction connection with the outdoor heat exchanger, and the second heat exchange pipeline is in heat conduction connection with the air conditioner controller; and the condensed water of the indoor unit flows into the first heat exchange pipeline to absorb heat from the outdoor heat exchanger and then flows into the second heat exchange pipeline to dissipate heat of the air conditioner controller.
In the prior art, the temperature of a controller of an air conditioner is abnormally high (generally reaching more than 60 ℃) in a high-temperature environment, so that the air conditioner cannot run at high frequency, and the refrigeration effect of the air conditioner is poor.
The invention provides the solution, and aims to reduce the temperature of the air conditioner controller and improve the refrigeration effect of the air conditioner.
The invention provides a heat dissipation device applied to an air conditioner controller 001. The air conditioner controller 001 may be a controller of the indoor unit 3 or an outdoor unit, and any controller of the air conditioner in a high temperature environment may be used as the air conditioner controller 001.
In this embodiment, when the air conditioner operates in a cooling mode or the like, the outdoor heat exchanger 1 of the air conditioner radiates heat as a condenser, and the controller 001 installed in the outdoor unit is susceptible to the condenser radiation heat and the ambient temperature, and thus the temperature is high, and therefore the air conditioner controller 001 mainly refers to a controller installed in the outdoor unit.
Referring to fig. 1, the air conditioner includes an outdoor heat exchanger 1, an indoor unit 3, and a controller 001. A heat sink is provided. The outdoor heat exchanger 1 is specifically a heat exchanger located in a refrigerant circulation circuit of the air conditioner and located outdoors. When the air conditioner is in an operation mode such as a cooling mode or a dehumidification mode, the outdoor heat exchanger 1 releases heat as a condenser. Wherein arrows of fig. 1 indicate the water flow direction of the condensed water.
Referring to fig. 1, the heat dissipation device of the controller 001 includes the first heat exchange pipeline 21 and a second heat exchange pipeline 22 communicated with the first heat exchange pipeline 21, the first heat exchange pipeline 21 is in heat conduction connection with the outdoor heat exchanger 1, and the second heat exchange pipeline 22 is in heat conduction connection with the air conditioner controller 001; the first heat exchange pipeline 21 is provided with a water inlet communicated with a condensed water outlet of the indoor unit 3 of the air conditioner. And the condensed water of the indoor unit 3 of the air conditioner flows into the first heat exchange pipeline 21 from the water inlet, absorbs heat from the outdoor heat exchanger 1, and then flows into the second heat exchange pipeline 22 to dissipate heat of the air conditioner controller 001. Make the comdenstion water before the heat dissipation of air conditioner controller 001, the comdenstion water passes through the suitable intensification of outdoor heat exchanger 1, because the excessive temperature difference produces the condensation on air conditioner controller 001 surface when avoiding the comdenstion water to carry out the heat exchange with air conditioner controller 001 to guarantee the normal operating of controller 001 simultaneously in the air conditioner controller 001 cooling.
The first heat exchange pipeline 21 and the second heat exchange pipeline 22 may be made of metal or other material with good heat conductivity. Specifically, the outer wall of the first heat exchange pipeline 21 is connected with fins and/or coils of the outdoor heat exchanger 1, and condensed water of the first heat exchange pipeline 21 can be arranged by contacting the outer wall with the outdoor heat exchanger 1, so that heat exchange with the outdoor heat exchanger 1 is realized. Specifically, the outer wall of the second heat exchange pipeline 22 is disposed in contact with a circuit substrate or a housing of the air conditioner controller 001, so as to realize heat exchange with the air conditioner controller 001. In other embodiments, the first heat exchange pipeline 21 and the outdoor heat exchanger 1, and the second heat exchange pipeline 22 and the air conditioner controller 001 may be arranged at intervals, and only the heat exchange between the two is required to be ensured. When the heat exchanger in the indoor air conditioner 3 is an evaporator and the outdoor heat exchanger 1 is a condenser, the condensed water generated by the indoor air conditioner 3 can enter the first heat exchange pipeline 21 from the water inlet and exchange heat with the outdoor heat exchanger 1 in the first heat exchange pipeline 21, and the temperature of the condensed water is low because the outdoor heat exchanger 1 is in a heat release state, so that the condensed water absorbs heat from the outdoor heat exchanger 1. The condensed water after absorbing heat flows from the first heat exchange pipeline 21 to the second heat exchange pipeline 22 communicated with the first heat exchange pipeline, the condensed water in the second heat exchange pipeline 22 exchanges heat with the air conditioner controller 001, and the condensed water absorbs heat from the air conditioner controller 001 due to the fact that the temperature of the condensed water is low and the temperature of the air conditioner controller 001 is high, so that the air conditioner controller 001 is cooled. The end of the second heat exchange pipeline 22 may further be provided with a water outlet, and condensed water after heat exchange with the air conditioner controller 001 may be discharged to the outside from the water outlet.
The heat dissipation device applied to the air conditioner controller 001 provided by the embodiment of the invention is based on an air conditioner comprising an outdoor heat exchanger and an indoor unit, the heat dissipation device comprises a first heat exchange pipeline 21 and a second heat exchange pipeline 22 communicated with the second heat exchange pipeline 22, the first heat exchange pipeline 21 is in heat conduction connection with the outdoor heat exchanger 1, the second heat exchange pipeline 22 is in heat conduction connection with the air conditioner controller 001, and condensed water of the indoor unit 3 of the air conditioner flows into the first heat exchange pipeline 21 to absorb heat from the outdoor heat exchanger 1, then the temperature of the condensed water is raised to an appropriate value, and then the condensed water flows into the second heat exchange pipeline 22 to dissipate heat of the air conditioner controller 001. In such a way, the air conditioner controller 001 is cooled by the condensed water of the air conditioner indoor unit 3, so that the temperature of the air conditioner controller 001 is reduced, and the refrigeration effect of the air conditioner is improved. Wherein, the comdenstion water is before the heat dissipation of air conditioner controller 001, and the comdenstion water passes through the suitable intensification of outdoor heat exchanger 1, because the great condensation that produces on air conditioner controller 001 surface of the temperature difference when avoiding the comdenstion water to carry out the heat exchange with air conditioner controller 001, avoids the condensation to lead to automatically controlled components and parts to damage or short circuit to lead to the trouble, consequently adopts above-mentioned mode to guarantee the normal operating of controller 001 simultaneously to air conditioner controller 001 cooling. Besides, in the scheme of the embodiment, the heat of the outdoor heat exchanger 1 is dissipated synchronously in addition to the heat dissipation of the air conditioner controller 001, so that the overall temperature of the outdoor unit is reduced, and the normal operation of each component in the outdoor unit is ensured.
Further, in this embodiment, referring to fig. 1, the heat dissipation device further includes a first switch device 02, and the first switch device 02 is disposed between the condensed water outlet and the water inlet. A first switch device 02 may be provided in the condensate drain opening, in the water inlet opening and/or at any position between the condensate drain opening and the water inlet opening except for two openings. The first switching device 02 is specifically a water flow switch, and when the first switching device 02 is turned on, condensed water in the indoor unit 3 can sequentially pass through the first heat exchange pipeline 21 and the second heat exchange pipeline 22 to dissipate heat of the air conditioner controller 001; when the first switch device 02 is turned off, the condensed water part of the indoor unit 3 can enter the heat dissipation device to dissipate heat of the air conditioner controller 001. In this implementation, through the setting of first switching device 02 to realize that the comdenstion water can carry out accurate control to air conditioner controller 001 heat dissipation as required, for example, just open first switching device 02 and dispel the heat to it at air conditioner controller 001 higher temperature, air conditioner controller 001 temperature is lower then does not open first switching device 02 and dispel the heat to it, thereby guarantees the normal operating of air conditioner. The first switching device 02 is embodied as a valve.
Further, referring to fig. 1, in this embodiment, the first heat exchange pipeline 21 includes a first heat exchange sub-pipeline 211 and a second heat exchange sub-pipeline 212, an end of the first heat exchange sub-pipeline 211, which is far away from the second heat exchange sub-pipeline 212, is provided with a water inlet of the first heat exchange pipeline 21, the water inlet is communicated with a condensed water outlet of the indoor air conditioner 3, and a water outlet of the second heat exchange sub-pipeline 212 is communicated with a water inlet of the second heat exchange sub-pipeline 22; the heat sink further comprises a bypass pipe 24 and a first flow direction switching device 23, a water outlet of the bypass pipe 24 is connected with a water inlet of the second heat exchange pipeline 22, a water outlet of the first sub heat exchange pipe 211, a water inlet of the second sub heat exchange pipe 212, and a water inlet of the bypass pipe 24 are all connected with the first flow direction switching device 23; the first flow direction switching device 23 can switch the flow direction of the condensed water, the first flow direction switching device 23 is in a first state and a second state, when the first flow direction switching device 23 is in the first state, the condensed water flows from the first heat exchange sub-tube 211 to the second heat exchange sub-tube 212, and when the first flow direction switching device 23 is in the second state, the condensed water flows from the first heat exchange sub-tube 211 to the bypass tube 24. In the present embodiment, the arrangement of the first flow direction switching device 23 and the bypass pipe 24 realizes the control of the heat absorption amount of the condensed water flowing into the first heat exchange pipeline 21 from the outdoor heat exchanger 1, so as to regulate and control the temperature of the condensed water flowing into the second heat exchange pipeline 22. If the temperature of the condensed water flowing into the first heat exchange pipeline 21 is low, the first flow direction switching device 23 can be in the first state, so that the condensed water can absorb large heat from the outdoor heat exchanger 1 to be properly heated through the first heat exchange sub-pipe 211 and the second heat exchange sub-pipe 212 in sequence; if the temperature of the condensed water flowing into the first heat exchange pipeline 21 is high, the first flow direction switching device 23 may be in the second state, so that the condensed water can extract less heat from the outdoor heat exchanger 1 through the first sub heat exchange pipe 211 to be properly warmed. By the above manner, the temperature of the condensed water entering the second heat exchange pipeline 22 can be ensured not to be too high, and the heat dissipation efficiency of the air conditioner controller 001 can be ensured; meanwhile, the temperature of the condensate water entering the second heat exchange pipeline 22 is not too low, so that the problem that the condensate water on the surface of the air conditioner fails due to the fact that the temperature difference between the condensate water and the air conditioner controller 001 is too large is avoided, and the normal operation of the air conditioner controller 001 can be further guaranteed while the air conditioner controller 001 dissipates heat.

Based on the air conditioner of the embodiment, the invention further provides a control method of the air conditioner. The air conditioner comprises an indoor unit 3, a controller 001, an outdoor heat exchanger 1 and a heat dissipation device, wherein the heat dissipation device comprises a first heat exchange pipeline 21 and a second heat exchange pipeline 22 communicated with the first heat exchange pipeline 21, the first heat exchange pipeline is in heat conduction connection with the outdoor heat exchanger, and the second heat exchange pipeline is in heat conduction connection with the controller.
Referring to fig. 3, there is provided a first embodiment of a control method of an air conditioner of the present invention, including:
step S10, if the air conditioner is in a refrigeration state, acquiring the outdoor environment temperature;
specifically, in the air-conditioning refrigeration operation or the dehumidification operation, the outdoor heat exchanger 1 is in a heat release state as a condenser, and the outdoor ambient temperature can be detected specifically by a temperature sensor provided outdoors.
Step S20, if the outdoor ambient temperature is greater than or equal to the temperature threshold, controlling the condensed water of the indoor unit 3 to flow into the first heat exchange pipeline 21 to absorb heat from the outdoor heat exchanger 1, and then to flow into the second heat exchange pipeline 22 to dissipate heat of the air conditioner controller 001.
The temperature threshold value can be set according to actual requirements, and is set comprehensively according to the temperature relation between the outdoor environment temperature and the temperature of the air conditioner controller 001 and the influence of the indoor heat exchanger on the temperature of the air conditioner controller 001. Specifically, the ambient temperature corresponding to the maximum temperature value of the air conditioner controller 001 when the cooling capacity of the air conditioner controller 001 is greater than or equal to the preset value in the heat release state of the outdoor heat exchanger 1 may be used as the temperature threshold value. For example, 35 ℃ may be used as the temperature threshold for the outdoor ambient temperature. When the outdoor environment temperature is greater than or equal to the temperature threshold, the temperature of the air conditioner controller 001 is higher, and the temperature needs to be reduced to ensure the air conditioner refrigerating capacity; if the outdoor environment temperature is less than the temperature threshold, it indicates that the temperature of the air conditioner controller 001 is normal, and the temperature does not need to be reduced.
When the heat dissipation device further includes a first switch device 02, the first switch device 02 is disposed between the condensed water outlet of the indoor unit 3 and the water inlet of the first heat exchange pipeline 21, and the step of controlling the condensed water of the indoor unit 3 to flow into the first heat exchange pipeline 21 to absorb heat from the outdoor heat exchanger 1, and then flow into the second heat exchange pipeline 22 to dissipate heat of the controller 001 includes: and controlling the first switching device 02 to be turned on, so that the condensed water of the indoor unit 3 flows into the first heat exchange pipeline 21 to absorb heat from the outdoor heat exchanger 1, and then flows into the second heat exchange pipeline 22 to dissipate heat of the controller 001. The first switching device 02 is embodied as a solenoid valve. When the outdoor environment temperature is greater than or equal to the temperature threshold value, the first switching device 02 is turned on, condensed water of the indoor unit 3 of the air conditioner flows into the first heat exchange pipeline 21, and the condensed water absorbs heat from the outdoor heat exchanger 1 in the first heat exchange pipeline 21 and is properly heated and then flows into the second heat exchange pipeline 22 to dissipate heat of the air conditioner controller 001. When the outdoor environment temperature is less than the temperature threshold, the air conditioner controller 001 may turn off the first switching device 02 without cooling.
In this embodiment, when the air conditioner is in a cooling state and the outdoor ambient temperature is too high, the first switch device 02 may be turned on, so that the condensed water in the indoor unit 3 of the air conditioner flows into the first heat exchange pipeline 21 to absorb heat from the outdoor heat exchanger 1, and then flows into the second heat exchange pipeline 22 to dissipate heat of the air conditioner controller 001. In such a way, the air conditioner controller 001 is cooled by the condensed water of the air conditioner indoor unit 3, so that the temperature of the air conditioner controller 001 is reduced, and the refrigeration effect of the air conditioner is improved. Wherein, the comdenstion water is before the heat dissipation of air conditioner controller 001, and the comdenstion water passes through the suitable intensification of outdoor heat exchanger 1, because the great condensation that produces of the difference in temperature when avoiding the comdenstion water to carry out the heat exchange with air conditioner controller 001, avoids the condensation to lead to automatically controlled components and parts to damage or short circuit to lead to the trouble, consequently adopts above-mentioned mode to guarantee the normal operating of controller simultaneously to air conditioner controller 001 cooling. Besides, in the scheme of the embodiment, the heat of the outdoor heat exchanger 1 is dissipated synchronously in addition to the heat dissipation of the air conditioner controller 001, so that the overall temperature of the outdoor unit is reduced, and the normal operation of each component in the outdoor unit is ensured.
Further, when the heat dissipation apparatus further includes a water tank 4, the water tank 4 has a first water discharge opening and a second water discharge opening, the first switch device 02 is disposed at the first water discharge opening, and the second water discharge opening is provided with a second switch device 41, after the step of obtaining the outdoor environment temperature when the outdoor heat exchanger 1 is in the heat release state, the method further includes: and when the outdoor environment temperature is lower than the temperature threshold, closing the first switch device 02, and opening the second switch device 41, so that the condensed water of the indoor unit 3 of the air conditioner is discharged through the second water outlet. The outdoor ambient temperature is less than or equal to the temperature threshold, indicating that the air conditioner controller 001 does not need to dissipate heat, so the first switching device 02 is turned off while the second switching device 41 is turned on, and the condensed water is discharged, thereby preventing the condensed water from being retained in the air conditioner.

In the second embodiment, the first heat exchange pipeline 21 is provided with a water inlet, the first heat exchange pipeline 21 comprises a first heat exchange sub-pipe 211 and a second heat exchange sub-pipe 212, one end of the first heat exchange sub-pipe 211, which is far away from the second heat exchange sub-pipe 212, is provided with a water inlet, a water outlet of the second heat exchange sub-pipe 212 is communicated with a water inlet of the second heat exchange pipeline 22, and the water inlet is communicated with a condensed water outlet of the indoor unit 3; the heat sink 24 further comprises a bypass pipe 24 and a first flow direction switching device 23, a water outlet of the bypass pipe 24 is connected with a water inlet of the second heat exchange pipe 22, and a water outlet of the first sub heat exchange pipe 211, a water inlet of the second sub heat exchange pipe 212, and a water inlet of the bypass pipe 24 are all connected with the first flow direction switching device 23; the first flow direction switching device 23 has a first state and a second state, when the first flow direction switching device 23 is in the first state, the condensed water flows from the first sub heat exchange tube 211 to the second sub heat exchange tube 212, and when the first flow direction switching device 23 is in the second state, the condensed water flows from the first sub heat exchange tube 211 to the bypass tube 24; referring to fig. 4, the step S20 includes:
step S30, obtaining a first outlet water temperature of the first sub heat exchange tube 211;

The first outlet water temperature is detected by a temperature sensor arranged at the water outlet of the first sub heat exchange tube 211. The first outlet water temperature is lower than the temperature threshold value, which indicates that after the condensed water absorbs heat through the first heat exchange sub-tube 211, the temperature of the condensed water is still lower, and the temperature difference between the condensed water and the air conditioner controller 001 is larger, and the condensed water cannot be directly used for heat dissipation of the air conditioner controller 001, so that the first flow direction switching device 23 needs to be controlled to be switched to the first state, and the condensed water flowing out of the first heat exchange sub-tube 211 flows into the second heat exchange sub-tube 212 to continuously absorb heat from the outdoor heat exchanger 1; the first outlet water temperature is greater than or equal to the temperature threshold value, which indicates that the first outlet water temperature is increased to the preset temperature range, and the first outlet water temperature can be directly used for radiating the air conditioner controller 001, so that the first flow direction switching device 23 can be controlled to be switched to the second state, and the condensed water flowing out of the first heat exchange sub-tube 211 directly flows into the second heat exchange tube 22 from the bypass tube 24 to radiate the air conditioner controller 001. Wherein, when the temperature of comdenstion water was located and predetermines the temperature range, the temperature that can think the comdenstion water is less than air conditioner controller 001's temperature, nevertheless can not too big with air conditioner controller 001's the difference in temperature, can not make air conditioner controller 001 produce the condensation, guarantees air conditioner controller 001 normal use, and the difference in temperature is enough big simultaneously to guarantee the heat transfer effect of comdenstion water to air conditioner controller 001. Therefore, this embodiment realizes the regulation and control to the comdenstion water temperature through above-mentioned mode, guarantees air conditioner controller 001's normal operating when the effective heat transfer of air conditioner controller 001.
Specifically, in the second embodiment, if the first outlet water temperature is greater than or equal to the temperature threshold, before executing step S32, the method further includes: determining a temperature difference value between the first outlet water temperature and the outdoor environment temperature as a first temperature difference value; if the first temperature difference value is less than or equal to a first threshold value, executing the step of controlling the first flow direction switching device 23 to switch to the second state; if the first temperature difference value is greater than the first threshold value, the step of controlling the first flow direction switching device 23 to switch to the first state is performed. The first threshold value may be set according to the actual situation, for example, 2 ℃. Since the higher the indoor environment temperature is, the higher the temperature of the air conditioner controller 001 is, the first temperature difference value is less than or equal to the first threshold value, and the difference between the temperature of the condensed water and the temperature of the air conditioner controller 001 is not too large, the condensed water can directly flow into the second heat exchange pipeline 22 to dissipate heat of the air conditioner controller 001; the first temperature difference value is larger than the first threshold value, which indicates that the temperature difference between the condensed water and the temperature of the air conditioner controller 001 is too large, and the temperature needs to be further increased through the outdoor heat exchanger 1. Therefore, through comparison of the first temperature difference value and the first threshold value, the air conditioner controller 001 can be further guaranteed to be adaptive to the current environment, and normal operation of the air conditioner controller 001 can be guaranteed while the air conditioner controller 001 can effectively dissipate heat through condensed water.
