[0012] Optionally, the inner diameter of the second interface is greater than the inner diameter of the third interface.

[0013] Optionally, the switch assembly further comprises: a first control valve arranged between the second end and the radiator and used for controlling the part of the heat dissipation pipeline between the second end and the radiator to be conducted or disconnected.

[0014] Optionally, the first control valve comprises a first one-way valve, and the conducting direction of the first one-way valve is from the first end to the second end of the heat dissipation pipeline.

[0015] Optionally, the switch assembly further comprises: a second control valve arranged between the first end and the radiator and used for controlling the part of the heat dissipation pipeline between the first end and the radiator to be conducted or disconnected.

[0016] Optionally, the second control valve comprises a second one-way valve, and the conducting direction of the second one-way valve is from the first end to the second end of the heat dissipation pipeline.

[0019] The air conditioning device provided by the embodiment of the present application can achieve the following technical effects:

[0020] In the refrigeration mode, the refrigerant flows into the outdoor heat exchanger through the exhaust port of the compressor, and the refrigerant flowing out of the outdoor heat exchanger flows into the heat dissipation pipeline through the first interface and the second interface.

The refrigerant flowing out of the radiator flows back to the compressor through the indoor heat exchanger.

[0022] In the heating mode, the refrigerant does not flow through the heat dissipation pipeline, and thus does not flow through the radiator. In this way, the temperature of the electronic control element after heat exchange with the radiator can be prevented from being too low due to the temperature of the refrigerant flowing out of the indoor heat exchanger being too low. The temperature of the electronic control element being too low can cause the electronic control element to produce condensation water, which can affect the operation reliability and safety of the electronic control element. Therefore, the application can prevent condensation water from being produced on the surface of the electronic control element, and can improve the stability and reliability of the operation of the electronic control element.

[0023] The liquid distribution structure is provided to balance the resistance of the radiator to the refrigerant flowing into the heat dissipation pipeline, so that the refrigerant can flow into the heat dissipation pipeline through the first interface and the second interface in the refrigeration mode, and the refrigerant can be prevented from flowing into the connecting pipeline through the third interface.

[0040] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0041] In combination with Figure 1 and Figure 2 As shown in the drawings, the present disclosure provides an air conditioning device, which comprises a compressor 30, an outdoor heat exchanger 10, and an indoor heat exchanger 20 connected in sequence through a pipeline, and further comprises a heat dissipation pipeline 105, a heat sink 102, a switch assembly, and a distribution structure 110.

[0042] The pipeline comprises a connecting pipeline 106 connected between the indoor heat exchanger 20 and the outdoor heat exchanger 10.

[0043] As shown in the drawings, Figure 1 The heat dissipation pipeline 105 is connected in parallel with the connecting pipeline 106, and the heat dissipation pipeline 105 comprises a first end 1051 and a second end 1052. In the refrigeration mode, the refrigerant flows from the first end 1051 to the second end 1052.

[0044] The heat sink 102 is arranged in the heat dissipation pipeline 105, and is used for dissipating heat of an electric control element 111 of the air conditioning device.

[0045] The switch assembly is arranged in the heat dissipation pipeline 105, and is used for controlling the heat dissipation pipeline 105 to be turned on in the refrigeration mode, and controlling the heat dissipation pipeline 105 to be turned off in the refrigeration mode.

[0046] The distribution structure 110 is arranged at the first end 1051 and / or the connecting pipeline 106, and comprises a first interface 107, a second interface 108 and a third interface 109. The first interface 107 is in communication with the outdoor heat exchanger 10, the second interface 108 is in communication with the heat dissipation pipeline 105, and the third interface 109 is in communication with the part of the connecting pipeline 106 which is in parallel connection with the heat dissipation pipeline 105. The first interface 107 is selectively in communication with at least one of the second interface 108 and the third interface 109. In the cooling mode, the first interface 107 is in communication with the second interface 108, and in the heating mode, the first interface 107 is in communication with the third interface 109.

[0047] The air conditioning device further comprises a reversing valve 40, which can be a combination of multiple valves or a four-way valve. Taking the four-way valve as an example, the four-way valve comprises a first connecting port 401 to a fourth connecting port 404. The exhaust port of the compressor 30 is in communication with the first connecting port 401, the second connecting port 402 is in communication with one end of the outdoor heat exchanger 10, the third connecting port 403 is in communication with one end of the indoor heat exchanger 20, and the fourth connecting port 404 is in communication with the return port of the compressor 30. The other end of the outdoor heat exchanger 10 is in communication with the other end of the indoor heat exchanger 20 through the connecting pipeline 106.

[0048] As shown in FIG. 1, Figure 1 In the cooling mode, the refrigerant flows through the exhaust port of the compressor 30, the first connecting port 401 and the second connecting port 402 into the outdoor heat exchanger 10 in sequence. The refrigerant flowing out of the outdoor heat exchanger 10 flows into the heat dissipation pipeline 105 through the first interface 107 and the second interface 108. Under the action of the switch assembly, the heat dissipation pipeline 105 is in an on state. The refrigerant flowing through the first end 1051 of the heat dissipation pipeline 105 flows to the second end 1052. The heat dissipation pipeline 105 exchanges heat with the electronic control element 111 to dissipate heat for the electronic control element 111. The refrigerant flowing out of the heat dissipation pipeline 102 flows back to the return port of the compressor 30 through the indoor heat exchanger 20, the third connecting port 403 and the fourth connecting port 404. In this application, the compressor 30 does not need to be used in the frequency reduction mode, so that the process of cooling the electronic control element 111 will not affect the normal operation of the air conditioning device.

[0049] As shown in FIG. 1, Figure 2 In the heating mode, the refrigerant flows through the exhaust port of the compressor 30, the first connecting port 401 and the third connecting port 403 into the indoor heat exchanger 20 in sequence. The switch assembly controls the heat dissipation pipeline 105 to be disconnected. The first interface 107 is in communication with the third interface 109. The refrigerant flowing out of the indoor heat exchanger 20 flows into the outdoor heat exchanger 10 through the connecting pipeline 106. The refrigerant flowing out of the outdoor heat exchanger 10 flows back to the return port of the compressor 30 through the outdoor heat exchanger 10, the second connecting port 402 and the fourth connecting port 404.

[0050] In the heating mode, the refrigerant does not flow through the heat dissipation pipeline 105, and thus does not flow through the heat sink 102, so that the temperature of the electric control element 111 after heat exchange with the heat sink 102 is prevented from being too low due to the refrigerant flowing out of the indoor heat exchanger 20, and the temperature of the electric control element 111 is prevented from being too low, which causes the electric control element 111 to produce condensation water and affects the operation reliability and safety of the electric control element 111. Therefore, the application can prevent the surface of the electric control element 111 from producing condensation water, and can improve the stability and reliability of the operation of the electric control element 111.

[0051] The distribution structure 110 is arranged, which can balance the resistance of the heat sink 102 to the refrigerant flowing into the heat dissipation pipeline 105, so that the refrigerant can flow into the heat dissipation pipeline 105 through the first interface 107 and the second interface 108 to dissipate heat for the electric control element 111 in the refrigeration mode, and the refrigerant is prevented from flowing into the part of the connection pipeline 106 connected in parallel with the heat dissipation pipeline 105 through the third interface 109.

[0052] Optionally, the distribution structure 110 is a three-way distribution structure 110, which includes a three-way valve.

[0053] The three-way valve includes the first interface 107, the second interface 108, and the third interface 109, which adopts the form of a three-way valve, can meet the flow direction of the refrigerant in the refrigeration and heating modes, and is a mature component with high operation reliability.

[0054] In the refrigeration mode, the first interface 107 is in communication with the second interface 108, and the first interface 107 is not in communication with the third interface 109. The refrigerant flows into the outdoor heat exchanger 10 through the discharge port of the compressor 30 in sequence, and the refrigerant flowing out of the outdoor heat exchanger 10 flows into the heat dissipation pipeline 105 through the first interface 107 and the second interface 108 to dissipate heat for the electric control element 111.

[0055] In the heating mode, the first interface 107 is in communication with the third interface 109, and the first interface 107 is in communication or not in communication with the second interface 108. The refrigerant flows into the indoor heat exchanger 20 through the discharge port of the compressor 30 in sequence, the switch assembly controls the heat dissipation pipeline 105 to be disconnected, the first interface 107 is in communication with the third interface 109, the refrigerant flowing out of the indoor heat exchanger 20 flows into the outdoor heat exchanger 10 through the third interface 109 and the first interface 107, and there is no refrigerant flowing into the heat dissipation pipeline 105.

[0056] Optionally, in the refrigeration mode, the first interface 107 is in communication with the second interface 108 and the third interface 109.

[0057] In the refrigeration mode, the first interface 107 is communicated with the second interface 108, and the first interface 107 is communicated with the third interface 109, and the refrigerant flows into the outdoor heat exchanger 10 in sequence through the exhaust port of the compressor 30, and the refrigerant flowing out of the outdoor heat exchanger 10 is divided into two paths, one path flows into the heat dissipation pipeline 105 through the first interface 107 and the second interface 108 to dissipate heat for the electric control element 111, and the other path flows into the connecting pipeline 106 through the first interface 107 and the third interface 109 to the part in parallel with the heat dissipation pipeline 105, so as to avoid that all the refrigerant flows through the heat dissipation pipeline 105 to cause the temperature of the electric control element 111 to be too low.

[0058] In the heating mode, the first interface 107 is communicated with the third interface 109, and under the action of the switch assembly, the heat dissipation pipeline 105 is disconnected, so that the first interface 107 can be communicated or not communicated with the second interface 108, and neither of them can cause the refrigerant to flow through the heat dissipation pipeline 105. Since the refrigerant does not flow through the heat dissipation pipeline 105 nor the radiator 102, the temperature of the refrigerant flowing out of the indoor heat exchanger 20 is prevented from being too low to cause the temperature of the electric control element 111 after heat exchange with the radiator 102 to be too low, and the temperature of the electric control element 111 being too low can cause the electric control element 111 to produce condensation water to affect the operation reliability and safety of the electric control element 111, thereby affecting the normal use of the electric control element 111 and reducing the service life.

[0059] Optionally, the inner diameter of the second interface 108 is greater than the inner diameter of the third interface 109, so that the resistance of the refrigerant flowing through the second interface 108 is smaller than the resistance of the refrigerant flowing through the third interface 109, so that in the refrigeration mode, under the condition that the third interface 109 is conducted, the refrigerant can still flow into the second interface 108 to balance the resistance of the radiator 102 and the switch assembly.

[0060] Optionally, the switch assembly further comprises a first control valve 103, and the first control valve 103 is arranged between the second end 1052 and the radiator 102 to control the opening and closing of the part of the heat dissipation pipeline 105 between the second end 1052 and the radiator 102.

[0061] The first control valve 103 is arranged between the second end 1052 of the heat dissipation pipeline 105 and the radiator 102, in the refrigeration mode, the first control valve 103 is opened, the part of the heat dissipation pipeline 105 between the second end 1052 and the radiator 102 is conducted, the refrigerant flowing through the radiator 102 passes through the first control valve 103 and the second end 1052 to flow into the indoor heat exchanger 20, and the refrigerant flowing back through the indoor heat exchanger 20 flows into the gas inlet of the compressor 30; in the heating mode, the first control valve 103 is closed, the part of the heat dissipation pipeline 105 between the second end 1052 and the radiator 102 is disconnected, which can prevent the refrigerant from flowing into the heat dissipation pipeline 105 through the second end 1052, thereby avoiding the electric control element 111 from producing condensation water.

[0062] Optionally, the first control valve 103 comprises a first one-way valve, and the first one-way valve is in a conducting direction from the first end 1051 to the second end 1052 of the heat dissipation pipeline 105.

[0063] The first one-way valve is a valve allowing only one-way flow. The one-way valve can prevent the reverse flow of the refrigerant and can be used to control the flow direction of the refrigerant. In the cooling mode, the first one-way valve is in a conducting state, and the part of the heat dissipation pipeline 105 between the radiator 102 and the second end 1052 is in a conducting state. The refrigerant flowing out of the outdoor heat exchanger 10 flows through the radiator 102 and the first one-way valve into the indoor heat exchanger 20. In the heating mode, the first one-way valve is in a closed state, and the part of the heat dissipation pipeline 105 between the radiator 102 and the second end 1052 is disconnected, and the refrigerant cannot flow through the first one-way valve. The first one-way valve can realize the opening or closing of the heat dissipation pipeline 105 by its own properties, without the need for a controller to control, so that the structure of the air conditioning device is simplified.

[0064] Optionally, the first control valve 103 comprises a first electromagnetic valve.

[0065] The first control valve 103 comprises a first electromagnetic valve. In the cooling mode, the first electromagnetic valve is in an open state, and in the heating mode, the first electromagnetic valve is in a closed state.

[0066] When the first control valve 103 is an electromagnetic valve, the on-off of the first electromagnetic valve can be controlled according to the heat dissipation requirement of the electric control element 111. In the cooling mode, when the electric control element 111 needs to be cooled, the first electromagnetic valve is controlled to be open, and when the electric control element 111 does not need to be cooled, the first electromagnetic valve is controlled to be closed, further improving the intelligent degree of the control of the air conditioning device.

[0067] Optionally, the switch assembly further comprises a second control valve 104, and the second control valve 104 is arranged between the first end 1051 and the radiator 102 and is used to control the on-off of the part of the heat dissipation pipeline 105 between the first end 1051 and the radiator 102.

[0068] The second control valve 104 is arranged between the first end 1051 of the heat dissipation pipeline 105 and the radiator 102. In the cooling mode, the second control valve 104 is opened, the part of the heat dissipation pipeline 105 between the first end 1051 and the radiator 102 is conducted, the refrigerant flows into the radiator 102 through the outdoor heat exchanger 10, the first interface 107 and the second interface 108, the second control valve 104, and the indoor heat exchanger 20 through the first control valve 103, and then flows back to the gas inlet of the compressor 30 through the indoor heat exchanger 20; in the heating mode, the second control valve 104 is closed, the part of the heat dissipation pipeline 105 between the first end 1051 and the radiator 102 is disconnected, which can prevent the refrigerant from flowing into the heat dissipation pipeline 105, so that the refrigerant temperature is not too low to cause the electric control element 111 to produce condensate water, thereby affecting the operation reliability and safety of the electric control element 111, and the stability and reliability of the electric control element 111 are improved, and the refrigerant flowing out of the indoor heat exchanger 20 flows into the outdoor heat exchanger 10 through the connecting pipeline 106.

[0069] Optionally, the second control valve 104 comprises a second one-way valve, and the conducting direction of the second one-way valve is from the first end 1051 to the second end 1052 of the heat dissipation pipeline 105, that is, the conducting direction of the second one-way valve is the same as that of the first one-way valve.

[0070] The second one-way valve is a valve that allows only one-way flow. The arrangement of the one-way valve can prevent the refrigerant from flowing in the opposite direction, and can be used to control the flow direction of the refrigerant. In the cooling mode, the second one-way valve is conducted, the part of the heat dissipation pipeline 105 between the radiator 102 and the first end 1051 is conducted, the refrigerant flowing out of the outdoor heat exchanger 10 flows into the second one-way valve through the first interface 107 and the second interface 108, and then flows into the radiator 102 through the second one-way valve, and then flows into the indoor heat exchanger 20 through the first one-way valve; in the heating mode, the second one-way valve is closed, the heat dissipation pipeline 105 is disconnected, and the refrigerant flows into the outdoor heat exchanger 10 through the connecting pipeline 106.

[0071] The second one-way valve can realize the closing or opening of the heat dissipation pipeline 105 by itself, without the need for a controller to control, so that the structure of the air conditioning device is simplified.

[0072] The refrigerant pressure at the first end 1051 is P2, and the refrigerant pressure at the second end 1052 is P1. In the cooling mode, P2>P1, the first one-way valve and the second one-way valve are opened, a part of the liquid refrigerant flows into the heat dissipation pipeline 105, and another part flows into the part of the connecting pipeline 106 connected in parallel with the heat dissipation pipeline 105; in the heating mode, the first one-way valve is reversely not conducted, P1=P2, and the second one-way valve does not reach the opening pressure difference condition and is not conducted.

[0073] Optionally, the second control valve 104 can also be a second electromagnetic valve.

[0074] In the cooling mode, the second electromagnetic valve is in the open state, and in the heating mode, the second electromagnetic valve is in the closed state.

[0075] And when the second control valve 104 is an electromagnetic valve, the on-off of the second electromagnetic valve can be controlled according to the heat dissipation requirement of the electric control element 111. In the cooling mode, when the electric control element 111 needs to be cooled, the second electromagnetic valve is controlled to be open, and when the electric control element 111 does not need to be cooled, the second electromagnetic valve is controlled to be closed, further improving the intelligent degree of the air conditioning equipment control.

[0077] The connecting section 1061 is connected between the first end 1051 of the heat dissipation pipeline 105 and the outdoor heat exchanger 10. In the cooling mode, the refrigerant flows through the outdoor heat exchanger 10 and the throttling element 101 to the first interface 107, and at least part of the refrigerant flows into the heat dissipation pipeline 105 through the first interface 107 and the second interface 108. Specifically, part of the refrigerant flows into the connecting pipeline and flows into the indoor heat exchanger 20, part of the refrigerant flows into the indoor heat exchanger 20 through the heat dissipation pipeline 105, or all the refrigerant flows into the indoor heat exchanger 20 through the heat dissipation pipeline 105. In the heating mode, the heat dissipation pipeline 105 is disconnected, the refrigerant flows through the connecting pipeline and the connecting section 1061, and flows into the outdoor heat exchanger 10 through the third interface 109 and the first interface 107.

[0078] The throttling element 101 is arranged in the connecting section 1061. In the cooling mode, the refrigerant first flows through the throttling element 101 and then flows through the radiator 102, thereby reducing the temperature of the electric control element 111, improving the performance of the electric control element 111, avoiding excessive cooling of the electric control element 111, preventing the radiator 102 from producing condensate water, and thereby ensuring the reliability of the electric control element 111.

[0079] Optionally, as shown in Figure 1 and Figure 2 The air conditioning equipment further comprises a connecting section 1061, the connecting section 1061 being connected between the second end 1052 and the indoor heat exchanger 20; the air conditioning equipment further comprises a throttling element 101, the throttling element 101 being arranged in the connecting section 1061.

[0080] The connecting section 1061 is connected between the second end 1052 of the heat dissipation pipeline 105 and the indoor heat exchanger 20, and the connecting pipeline is connected in parallel with the heat dissipation pipeline 105. In the cooling mode, at least part of the refrigerant flowing out of the outdoor heat exchanger 10 flows through the heat dissipation pipeline 105, flows into the connecting section 1061 through the second end 1052, and flows into the indoor heat exchanger 20. Specifically, part of the refrigerant flows into the indoor heat exchanger 20 through the heat dissipation pipeline 105, part of the refrigerant flows into the indoor heat exchanger 20 through the connecting pipeline, or all of the refrigerant flows into the indoor heat exchanger 20 through the heat dissipation pipeline 105; in the heating mode, the heat dissipation pipeline 105 is disconnected, the refrigerant flows through the connecting section 1061 and the connecting pipeline, flows into the outdoor heat exchanger 10 through the third interface 109 and the first interface 107.

[0081] The throttling element 101 is arranged in the connecting section 1061. In the cooling mode, the refrigerant flowing through the heat dissipation pipeline 105 flows into the heat sink 102 and then flows through the throttling element 101, so that the temperature of the refrigerant in the heat sink 102 is appropriate, preventing the temperature of the refrigerant from being lowered below the ambient dew point temperature after flowing through the throttling element 101, so that the temperature of the refrigerant is too low, causing condensed water to be generated on the surface of the electronic control element 111, ensuring the service life and safety of use of the electronic control element 111. Moreover, since the refrigerant flows through the heat sink 102 first and then flows through the throttling element, the refrigerant in the heat sink 102 has a large cold energy density, and the heat dissipation effect on the electronic control element 111 is better.

[0082] Optionally, the electronic control element 111 is arranged outdoors, and the heat sink 102 is arranged correspondingly to the electronic control element 111.

[0083] The heat sink 102 is provided with a flow pipeline for the refrigerant to pass through, and the refrigerant flow path is connected in series on the heat dissipation pipeline. The surface of the heat sink 102 is also provided with a fin structure. The air conditioning device includes an outdoor unit, and the outdoor unit is provided with a fan arranged correspondingly to the outdoor heat exchanger 10, which is used to drive air to flow through the outdoor heat exchanger 10 to exchange heat with the outdoor heat exchanger 10. The air driven by the fan can also flow through the fin structure to cool the heat sink 102, thereby cooling the electronic control element 111.

[0084] In the heating mode, the refrigerant does not flow through the heat dissipation pipeline 105, and the fan is used to cool the electronic control element 111.

[0085] The air conditioning device can be an air conditioner or a heat pump unit.
