One end of the heat conduction mechanism is connected to the electrical box, and the other end is connected to the refrigerant pipeline of the air conditioner itself. The low temperature in the refrigerant pipeline is dissipated to the electrical box through the heat conduction mechanism. However, the refrigerant pipeline has a certain vibration due to the operation of the compressor, and the vibration is transmitted to the heat conduction mechanism and even the electrical box, which is easy to affect the reliability of the heat conduction mechanism and the electrical box components.

[0041] In order to solve the problems in the prior art, the present application provides a heat dissipation component and an air conditioner. When the heat dissipation component performs liquid cooling on the electrical box, it can effectively prevent the vibration of the compressor from being transmitted to the heat conduction mechanism and the electrical box, thereby ensuring the reliable operation of the heat conduction mechanism and the electrical box.

[0042] Figure 1 A schematic diagram of a planar structure of a heat dissipation assembly provided in an embodiment of the present application is shown; Figure 2 A schematic diagram showing a heat dissipation component provided in an embodiment of the present application for dissipating heat from an electrical box; Figure 3A schematic diagram showing another heat dissipation component provided in an embodiment of the present application for dissipating heat from an electrical box; Figure 4 A schematic diagram of the structure of a heat dissipation component and a compressor provided in an embodiment of the present application is shown; Figure 5 A schematic diagram of the structure of an air conditioner outdoor unit provided in an embodiment of the present application is shown; Figure 6 An exploded structural block diagram of a heat dissipation component and an electrical box provided in an embodiment of the present application is shown;

[0043] like Figure 1-6 As shown, an embodiment of the present application provides a heat dissipation component for dissipating heat from an electrical box 4 , and the heat dissipation component includes: a heat conduction mechanism 1 , an air-conditioning refrigerant pipeline 2 , and a branch hose 3 .

[0044] The heat conducting mechanism 1 has a heat absorbing end 11 and a heat dissipating end 12 for heat exchange. The heat absorbing end 11 is used to absorb the heat dissipated by the electrical box 4 .

[0045] The air-conditioning refrigerant pipeline 2 is filled with refrigerant.

[0046] The branch hose 3 is connected to the air-conditioning refrigerant pipeline 2 , and the branch hose 3 abuts against the heat dissipation end 12 of the heat conduction mechanism 1 to take away the heat of the heat dissipation end 12 .

[0047] In the present application, the heat generated by the electrical box 4 is absorbed by the heat absorbing end 11 of the heat conducting mechanism 1, and the heat is taken away at the heat dissipating end 12 through the branch hose 3 connected to the air-conditioning refrigerant pipeline 2, so as to realize liquid cooling of the electrical box 4. The branch hose 3 can effectively reduce the vibration transmission of the compressor 5 through the air-conditioning refrigerant pipeline 2 to the heat conducting mechanism 1, thereby effectively preventing the vibration of the compressor 5 from being transmitted to the heat conducting mechanism 1 and the electrical box 4, thereby ensuring the reliability of the heat conducting mechanism 1 and the electrical box 4.

[0048] Specifically, the refrigerant pipe in the air-conditioning refrigerant pipeline 2 circulates regularly, a section of the air-conditioning refrigerant pipeline 2 with a lower temperature is selected, and then the branch hose 3 is connected, so that at least part of the refrigerant in the air-conditioning refrigerant pipeline 2 can flow through the branch hose 3. The branch hose 3 is used to dissipate heat at the heat dissipation end 12 of the heat conduction mechanism 1, and the branch hose 3 is made of flexible material, which can effectively prevent the vibration generated at the compressor 5 from being transmitted to the branch hose 3 through the air-conditioning refrigerant pipeline 2, thereby reducing the impact of the vibration on the heat conduction mechanism 1 and the electrical box 4.

[0049] like Figure 7As shown, in the related art, household air conditioners often use a refrigerant ring solution, and the low-temperature refrigerant substrate 13 is in direct contact with the control device, which is easily damaged by condensation and short circuit. In order to solve the condensation problem, two sets of electronic expansion valve devices are often added before and after the substrate 13 of the refrigerant ring, which is costly. Because of the risk of condensation, the refrigerant heat dissipation method cannot use the system's lowest temperature compressor 5 suction refrigerant pipe, and a throttle valve is used to control the temperature. The system tests that the temperature is greater than 10°C or above the suction pipe.

[0050] In the present application, the air conditioning refrigerant pipeline 2 dissipates heat to the electrical box 4 through the heat conduction mechanism 1, which can avoid condensation damage to the electrical box 4 due to excessive low temperature, and protect the components in the electrical box 4.

[0051] In some embodiments, the air conditioning refrigerant pipeline 2 includes an air intake pipe 21 connected to the air intake end of the compressor 5 , and the branch hose 3 is connected to the air intake pipe 21 .

[0052] In this application, the air intake pipe 21 in the air conditioning refrigerant pipeline 2 is selected because the air intake pipe 21 has a lower temperature, which can make the branch hose 3 connected to the air intake pipe 21 also have a lower temperature, thereby ensuring the heat dissipation effect on the heat conduction mechanism 1 and the electrical box 4; and the air intake pipe 21 is connected to the air intake end of the compressor 5. When the gaseous refrigerant returns to the compressor 5 through the air intake pipe 21, sometimes there will be droplets of a certain component in the gaseous refrigerant, which will cause liquid hammer when returning to the compressor 5, thereby causing vibration of the air intake pipe 21. Connecting the branch hose 3 to the air intake pipe 21 is equivalent to heating the refrigerant in the air intake pipe 21 through the heat conduction mechanism 1, so that some of the droplets in the air intake pipe 21 can be turned into gas again, thereby avoiding liquid hammer when the refrigerant returns to the compressor 5, and further reducing the vibration of the air intake pipe 21.

[0053] In one embodiment, the branch hose 3 is arranged in parallel with the air intake pipe 21 , and the air intake pipe 21 and the branch hose 3 are respectively connected to the liquid storage tank 51 of the compressor 5 .

[0054] In the present application, the branch hose 3 is connected in parallel with the intake pipe 21, so that part of the refrigerant returns to the liquid storage tank 51 of the compressor 5 through the intake pipe 21, and the other part of the refrigerant returns to the liquid storage tank 51 through the branch hose 3. By making the branch hose 3 independent of the outside of the intake pipe 21, the influence of the vibration of the intake pipe 21 on the branch hose 3 can be minimized, and the influence of the vibration on the heat transfer mechanism 1 and the electrical box 4 can be further reduced.

[0055] In some embodiments, a regulating valve 6 is provided on the branch hose 3 or the air intake pipe 21 to regulate the flow rate flowing through the branch hose 3 .

[0056] In the present application, the flow rate in the branch hose 3 can be adjusted by the regulating valve 6, and the heat exchange efficiency of the branch hose 3 to the heat conducting mechanism 1 can be adjusted, thereby adjusting the heat dissipation effect of the electrical box 4.

[0057] In another embodiment, the branch hose 3 is arranged in series with the air intake pipe 21 , and the air intake pipe 21 is connected to the liquid storage tank 51 of the compressor 5 .

[0058] In the present application, the branch hose 3 can also be arranged in series with the intake pipe 21. One end of the intake pipe 21 is connected to the branch hose 3, and the other end is connected to the liquid storage tank 51. This can not only reduce the amount of droplets in the refrigerant entering the intake pipe 21 to prevent liquid hammer, but also effectively prevent the vibration of the compressor 5 from being transmitted to the branch hose 3.

[0059] In some embodiments, the air intake pipe 21 is in communication with the liquid storage tank 51 of the compressor 5 , and a buffer member 7 is provided at the connection between the air intake pipe 21 and the liquid storage tank 51 .

[0060] In the present application, a buffer member 7 is provided at the connection between the air intake pipe 21 and the liquid storage tank 51 . The buffer member 7 may be processed by a rubber process such as a wire drawing, thereby reducing the transmission of the vibration of the compressor 5 to the air intake pipe 21 .

[0061] In some embodiments, the heat dissipation assembly further includes a damping block 8 disposed on the air intake pipe 21 for absorbing vibrations on the air intake pipe 21 .

[0062] In the present application, the damping block 8 fixes the air intake pipe 21, which can further reduce the transmission of stress and thus reduce the transmission of vibration.

[0063] In some embodiments, the heat conduction mechanism 1 includes a substrate 13 and a heat conduction pipe 14 arranged on the substrate 13. The substrate 13 includes a heat dissipation module 132 and a heat absorption module 131. The heat dissipation module 132 and the heat absorption module 131 exchange heat through the heat conduction pipe 14, and the heat absorption module 131 abuts against the electrical box 4.

[0064] In the present application, the heat absorption module 131 and the heat dissipation module 132 of the substrate 13 exchange heat through the heat pipe 14, the heat absorption module 131 exchanges heat with the components, and the heat dissipation module 132 exchanges heat with the refrigerant pipe, thereby realizing the heat dissipation of the components. By separating the heat absorption module 131 and the heat dissipation module 132, condensed water can be prevented from flowing onto the components, further protecting the components and ensuring that the temperature at the heat absorption module 131 is not too low to cause condensation on the components.

[0065] In some embodiments, the heat absorption module 131 and the heat dissipation module 132 are spaced apart from each other, and a gap is left between the heat absorption module 131 and the heat dissipation module 132 .

[0066] In the present application, the heat absorption module 131 and the heat dissipation module 132 of the substrate 13 exchange heat through the heat pipe 14, the heat absorption module 131 exchanges heat with the components, and the heat dissipation module 132 exchanges heat with the refrigerant pipe, thereby realizing the heat dissipation of the components. By separating the heat absorption module 131 and the heat dissipation module 132, condensed water can be prevented from flowing onto the components, further protecting the components and ensuring that the temperature at the heat absorption module 131 is not too low to cause condensation on the components.

[0067] In one embodiment, the substrate 13 adopts an integral structure, and the heat absorption module 131 and the heat dissipation module 132 are separated by a heat insulation module, so that there can be a temperature difference between the heat absorption module 131 and the heat dissipation module 132 to avoid condensation due to the temperature of the heat absorption module 131 being too low.

[0068] In another embodiment, the heat absorption module 131 and the heat dissipation module 132 are separately provided so as to achieve that there is no direct heat exchange between the heat absorption module 131 and the heat exchange module, thereby ensuring that there can be a temperature difference between the heat absorption module 131 and the heat dissipation module 132, thereby avoiding the phenomenon of condensation due to the temperature of the heat absorption module 131 being too low.

[0069] In some embodiments, the heat pipe 14 has a first end 141 that is attached to the heat absorption module 131 and a second end 142 that is attached to the heat dissipation module 132; the heat absorption module 131 and / or the first end 141 form the heat absorption end 11 of the heat conduction mechanism 1; the heat dissipation module 132 and / or the second end 142 form the heat dissipation end 12 of the heat conduction mechanism 1.

[0070] In the present application, the first end 141 of the heat pipe 14 is attached to the heat absorption module 131 to exchange heat with the heat absorption module 131 , and the second end 142 of the heat pipe 14 is attached to the heat dissipation module 132 to exchange heat with the heat dissipation module 132 .

[0071] In one embodiment, the heat absorption module 131 of the substrate 13 is bonded to the components and serves as the heat absorption end 11 for absorbing the heat emitted by the components. The temperature of the heat absorption module 131 of the substrate 13 is not too low, so that condensation will not occur on the components. In another embodiment, the first end 141 of the heat pipe 14 is bonded to the components and serves as the heat absorption end 11 for absorbing the heat emitted by the components, so that the components can be cooled more directly. In yet another embodiment, the heat absorption module 131 of the substrate 13 and the first end 141 of the heat pipe 14 together serve as the heat absorption end 11 for absorbing the heat emitted by the components.

[0072] In one embodiment, the heat dissipation module 132 of the substrate 13 is bonded to the refrigerant tube and serves as a heat dissipation end 12 for transferring heat to the refrigerant tube; in another embodiment, the second end 142 of the heat pipe 14 is bonded to the refrigerant tube and serves as a heat dissipation end 12 for transferring heat to the refrigerant tube. The temperature of the second end 142 of the heat pipe 14 is higher than that of the heat dissipation module 132. The heat dissipation effect can be ensured by directly bonding the second end 142 of the heat pipe 14 to the refrigerant tube; in yet another embodiment, the second end 142 of the heat pipe 14 and the heat dissipation module 132 are used together as the heat dissipation end 12 and bonded to the refrigerant tube to transfer heat to the refrigerant tube, which can further improve the heat dissipation effect.

[0073] Preferably, the present application selects the heat absorption module 131 of the substrate 13 as the heat absorption end 11. The heat absorption module 131 is bonded to the components to absorb the heat generated by the components, which can avoid the phenomenon of condensation of the components caused by the overcooled heat pipe 14 directly contacting the components, thereby protecting the components; the heat dissipation module 132 of the substrate 13 and the second end 142 of the heat pipe 14 are jointly used as the heat dissipation end 12 to contact the refrigerant pipe, thereby ensuring the heat exchange efficiency between the heat dissipation end 12 and the refrigerant pipe.

[0074] In some embodiments, the heat pipe 14 is filled with cooling liquid, which is vaporized into gas phase at the first end 141 and flows to the second end 142 , and condensed into liquid phase at the second end 142 and flows to the first end 141 .

[0075] In the present application, the interior of the heat pipe 14 is filled with a coolant, and the coolant is in a two-phase form. The coolant is in a liquid state at the first end 141, and becomes a gas after absorbing heat and flows to the second end 142, thereby carrying the heat to the second end 142. After dissipating heat at the second end 142, it becomes a liquid state and returns to the first end 141 again. Heat conduction through the two-phase coolant has a better heat conduction effect than direct heat conduction through a conductor, and a certain temperature difference can be made between the first end 141 and the second end 142 of the heat pipe 14. The temperature of the first end 141 is higher than the temperature of the second end 142, and the heat absorption module 131 and components can also be protected.

[0076] Optionally, the heat pipe 14 may also be made of a material with good thermal conductivity, such as copper, aluminum, etc.

[0077] In some embodiments, a height of the first end 141 is lower than a height of the second end 142 .

[0078] In the present application, by making the height of the first end 141 of the heat pipe 14 lower than the height of the second end 142, because the second end 142 is in direct contact with the refrigerant pipe and has a lower temperature, it is used for condensing the coolant in the heat pipe 14, and it is more convenient for the cooling water condensed at the second end 142 to return to the first end 141, and the gas generated by the first end 141 due to heating flows upward and naturally flows to the second end 142. In the vertical direction, the heat pipe 14 has the gas above the working fluid inside the heat pipe 14 being cooled and turned into liquid and flowing downward, and the liquid below being evaporated by the heat source and turned into gas and floats up, so that the coolant forms a circulation in the heat pipe 14, further improving the heat exchange effect and heat exchange efficiency of the heat pipe 14.

[0079] The heat dissipation component absorbs the heat generated by the electrical box 4 through the heat absorption end 11 of the heat conduction mechanism 1, and takes away the heat at the heat dissipation end 12 through the branch hose 3 connected to the air-conditioning refrigerant pipeline 2, thereby realizing liquid cooling of the electrical box 4. The branch hose 3 can effectively reduce the vibration transmission of the compressor 5 through the air-conditioning refrigerant pipeline 2 to the heat conduction mechanism 1, thereby effectively preventing the vibration of the compressor 5 from being transmitted to the heat conduction mechanism 1 and the electrical box 4, thereby ensuring the reliability of the heat conduction mechanism 1 and the electrical box 4.

[0080] An embodiment of the present application provides an air conditioner, comprising: a casing 9; an electrical box 4, disposed in the casing 9; a compressor 5, disposed in the casing 9; and the above-mentioned heat dissipation component, wherein the heat conduction mechanism 1 of the heat dissipation component is used for heat dissipation of the electrical box 4, and the air conditioning refrigerant pipeline 2 of the heat dissipation component is connected to the compressor 5.

[0081] In the present application, the air-conditioning refrigerant pipeline 2 of the heat dissipation component is externally connected to the branch hose 3, and the heat transfer mechanism 1 is heat-exchanged through the branch hose 3, and the heat transfer mechanism 1 dissipates heat to the electrical box 4, thereby realizing liquid cooling of the internal components of the electrical box 4. At the same time, when the vibration generated by the compressor 5 is transmitted to the branch hose 3, since the branch hose 3 is a flexible tube, the conduction of the vibration can be effectively reduced, thereby reducing the impact of the vibration on the heat transfer mechanism 1 and the electrical box 4.
