In practical application, the evaporation part 10 is arranged close to the heating element, and the heat transfer working medium flows in the heat transfer working medium pipeline of the evaporation part 10, so that the heat generated by the heating element can be absorbed and changed into a gaseous state.

The heat transfer working medium pipeline comprises a first pipe group 31, a connecting pipe 32 and a second pipe group 33 which are communicated in sequence, and the flow direction of the heat transfer working medium flows from the first pipeline to the connecting pipe 32 and from the connecting pipe 32 to the second pipe group 33. The first tube group 31 comprises a fluid inlet tube 310 and a first shunt tube which are arranged in series, and the heat transfer working medium enters from the fluid inlet tube 310, then flows to the first shunt tube to be shunted, and flows out from the first shunt tube to enter the connecting tube 32 for confluence. Like this, heat transfer working medium can fully absorb the heat that heating element produced through reposition of redundant personnel and confluence, promotes the radiating effect.

Optionally, the heat transfer working fluid is a phase change working fluid that is phase changeable. Optionally, the heat transfer working fluid is an electronic fluorinated liquid.

For example, in a high-temperature external environment, the temperature of the frequency conversion module rises faster, and the heat sink provided by the embodiment of the disclosure has the capability of dissipating heat of the frequency conversion module in the high-temperature environment.

As shown in connection with fig. 1, 2 or 3, optionally, the fluid inlet tube 310 is partially inside the base body and partially extends to the outside of the substrate 20. In this way, the fluid inlet pipe 310 can communicate with the condensation portion 40 of the heat sink at one end outside the base plate 20 and with the first shunt pipe at one end inside the base body, so that the heat transfer medium can flow between the evaporation portion 10 and the condensation portion 40.

As shown in fig. 1, the first shunt tube is optionally bent with respect to the fluid inlet tube 310. The first shunt pipe is bent relative to the fluid, and the flow direction of the heat transfer working medium is changed when the heat transfer working medium flows to the first shunt pipe from the fluid inlet pipe 310, so that the turbulent effect of the heat transfer working medium can be enhanced, the heat exchange area between the heat transfer working medium pipeline and the outside is increased, and the heat absorption effect of the heat transfer working medium is enhanced. Optionally, the connecting tube 32 is bent with respect to the first shunt tube.

As shown in connection with fig. 1, optionally, the fluid outlet pipe 330 includes a bent pipe section disposed at an outer periphery of the second branch pipe and the connection pipe 32. The outer periphery of the second shunt tube and the connection tube 32 means that the second shunt tube and the connection tube 32 are located on the same plane in the substrate 20, and the outer periphery is the outer periphery of the region where the second shunt tube and the connection tube 32 are located. The bending pipe section surrounds the periphery of the second shunt pipe and the connecting pipe 32, can extend to more areas in the base plate 20 as far as possible, increases the heat exchange area with the heating element, improves the temperature uniformity of the base plate 20, and enhances the heat absorption effect of the heat transfer working medium. Moreover, the fluid outlet pipe 330 is extended to the side of the substrate 20 extending out of the fluid inlet pipe 310, so that the structure of the evaporation part 10 is more compact and reasonable, and the installation of the heat sink is facilitated.

Optionally, the second heat transfer medium circuit includes one or more capillary segments 70. The arrangement of the capillary tube section 70 increases the pressure in the heat transfer working medium circulation loop on one hand, is beneficial to the circulation flow of the heat transfer working medium in the heat transfer working medium circulation loop, improves the fluidity and the flow rate of the heat transfer working medium in the heat transfer working medium circulation loop, and improves the heat dissipation efficiency of the radiator. For example, under the non-vacuum condition of the heat transfer working medium circulation loop, the self-circulation flow of the heat transfer working medium in the heat transfer working medium circulation loop can be realized; or, under the condition that the evaporation part 10 and the condensation part 40 are positioned at the same horizontal plane, the self-circulation flow of the heat transfer working medium in the heat transfer working medium circulation loop can be realized; in the second aspect, the capillary segment 70 has the function of reducing temperature and pressure, and can reduce the temperature of the heat transfer medium for the second time, thereby improving the heat dissipation effect of the heat sink.

As shown in fig. 2, optionally, the lower surface of the base plate 20 is provided with a first fin 21. The first fins 21 can release part of the heat of the evaporation portion 10, and enhance the heat radiation effect. Alternatively, the number of the first fins 21 is plural and arranged at intervals. The first fins 21 arranged at intervals can effectively improve the heat dissipation effect. Alternatively, the upper surface of the base plate 20 is provided with a high-step portion and a low-step portion, the low-step portion is provided with a pipe-inserting groove 22, and the fluid inlet pipe 310 and the fluid outlet pipe 330 are inserted into the pipe-inserting groove 22 and extend into the high-step portion. The pipe-inserting groove 22 is used for inserting the fluid inlet pipe 310 and the fluid outlet pipe 330, and the fluid inlet pipe 310 and the fluid outlet pipe 330 can be kept firm and stable.

As shown in fig. 5, optionally, the outdoor unit of the air conditioner further includes an electronic control box 80, and the base plate 20 is disposed at the electronic control box 80. In this way, the evaporation portion 10 can dissipate heat of the electric control elements in the electric control box 80.

As shown in connection with fig. 1, in some embodiments, the second tube set 33 includes a second shunt tube and a fluid outlet tube 330, the second shunt tube being in communication with the connection tube 32 and including a plurality of second sub-tubes 331 arranged in parallel; the fluid outlet pipe 330 communicates with the second shunt pipe. The heat transfer working medium flows out of the connecting pipe 32 and then enters the second shunt pipe, the second shunt pipe comprises a plurality of second sub-pipes 331 which are arranged in parallel, the heat transfer working medium is shunted and enters the second sub-pipes 331, external heat is fully absorbed, and the heat dissipation effect of the radiator is improved. The plurality of second sub-tubes 331 are arranged in parallel, and the region where the plurality of second sub-tubes 331 are located can efficiently absorb heat. The heat transfer working medium flows out from the second shunt pipe, then joins the fluid outlet pipe 330, flows along the fluid outlet pipe 330 to continuously absorb heat, and finally flows out of the evaporation part 10 from the fluid outlet pipe 330.

Through the embodiment, the heat transfer working medium is shunted in the first shunt pipe, is converged at the connecting pipe 32, is shunted again in the second shunt pipe, is converged again in the fluid outlet pipe 330, and fully absorbs the heat outside the evaporation part 10 after continuous shunting and converging, thereby improving the heat dissipation efficiency of the radiator. Especially for the mainboard with a plurality of chips, when the radiator radiates heat, the heat transfer working medium is shunted and converged for many times in the substrate 20, and the temperature uniformity of the substrate 20 of the radiator can be improved. As shown in fig. 3, in the inverter module having a plurality of chips 81, the heat flux density of each chip 81 is different, and the positions of the first sub-pipe 311 and a part of the second sub-pipe 331 of the heat sink correspond to the areas where the chips having smaller heat flux densities are located. Therefore, the position of part of the second sub-tube 331 corresponds to the area where the chip with higher heat flux density is located, and the heat transfer working medium flows through the first sub-tube 311, the connecting tube 32 and the second sub-tube 331 in sequence, so that the heat of the chip with lower heat flux density can be firstly dissipated, and then the chip with higher heat flux density can be dissipated. Like this, can avoid giving the less chip of heat flux density with the great chip heat of heat flux density retransmission, promote the radiating effect to a plurality of chips.

The continuous bending prolongs the flow path of the heat transfer working medium and enhances the absorption of heat.

In some embodiments, the fluid outlet tube 330 is at a higher level than the fluid inlet tube 310. According to the heat dissipation principle of heat transfer from bottom to top, the heat transfer working medium absorbs heat and turns into a gaseous state, and then the gaseous state tends to flow upwards. The horizontal height of the fluid outlet pipe 330 is higher than that of the fluid inlet pipe 310, and the liquid heat transfer working medium absorbs heat and gradually changes into a gas state and flows upwards after entering from the fluid inlet pipe 310, so that the heat transfer working medium flows out from the fluid outlet pipe 330, the flowing power of the heat transfer working medium is increased, and the circulating flow of the heat transfer working medium is promoted. Optionally, the connection line between the fluid outlet pipe 330 and the fluid inlet pipe 310 forms an angle of 1 ° with the horizontal line. Therefore, the gaseous heat transfer working medium can be effectively promoted to be discharged from the fluid outlet pipe 330, and the circulating flow of the heat transfer working medium is promoted.

In some embodiments, optionally, the ratio of the diameter of the second sub-tube 331 to the connecting tube 32 is 1.2 to 1. Therefore, the flow of the heat transfer working medium in the pipe is facilitated, and the flow resistance of the heat transfer working medium is reduced. Alternatively, the diameter ratio of the second sub-pipe 331 to the connecting pipe 32 is 1.2, the pipe diameter of the connecting pipe 32 is the same as that of the first sub-pipe 311, and the pipe diameter of the fluid inlet pipe 310 is the same as that of the first sub-pipe 311. Therefore, the flow of the heat transfer working medium in the pipe can be further promoted, and the flow resistance of the heat transfer working medium is reduced. Alternatively, the fluid inlet pipe 310, the first sub-pipe 311 and the connecting pipe 32 all have a pipe diameter of 5mm, and the second sub-pipe 331 has a pipe diameter of 6mm. The heat transfer medium flow can be promoted by manufacturing the pipelines according to the size.

In some embodiments, the plane formed by the first tube group 31, the connection tube 32, and the second tube group 33 is inclined with respect to the horizontal plane, and the height of the second tube group 33 is higher than the height of the first tube group 31. Thus, the heat transfer medium line is inclined as a whole, and the height gradually increases from the first tube group 31 to the second tube group 33, so that the flow of the heat transfer medium from the first tube group 31 to the second tube group 33 is promoted, and the outflow of the gaseous heat transfer medium from the fluid outlet is facilitated.

With reference to fig. 6, an embodiment of the present disclosure further provides a method for adjusting an outdoor unit of an air conditioner provided in any one of the foregoing embodiments, where the outdoor unit further includes a first fan, a condensing portion of the heat sink is disposed on an air supply path of the first fan, and the method includes:

The rotating speed of the first fan is adjusted according to the heat transfer working medium flow of the condensation part, so that the heat dissipation effect of the condensation part of the heat sink is improved, and the heat dissipation efficiency of the heat sink is integrally improved. The detection of the heat transfer working medium flow can be realized by arranging a liquid flow meter on the heat transfer working medium pipeline of the condensation part.

The heat transfer working medium carries heat to flow into the heat transfer working medium pipeline of the condensation part 40 to be released, the condensation part 40 is arranged on the air supply path of the first fan 51, so that the air flow formed by the first fan 51 passes through the condensation part 40, and the heat dissipation efficiency of the condensation part 40 can be effectively improved. The condensing unit 40 is located on the air blowing path of the first fan 51, and the rotational speed of the first fan 51 is adjusted according to the flow rate of the heat transfer medium in the condensing unit 40, so that the adjustment can be more accurate.

Thus, the air flow outside the casing 60 is introduced from the inlet 61 by the rotation of the first fan 51, and the air flow passes through the first fan 51 and the condenser 40 and then flows out from the outlet 62. The casing 60 and the first fan 51 are arranged, the first fan 51 can be specially used for radiating the condensation part 40, air flow generated by the first fan 51 penetrates through the radiating cavity 63, sufficient heat radiation of the condensation part 40 is guaranteed, interference of the second fan 52 used for radiating heat of the heat exchanger in the air conditioner outdoor unit on the air flow of the first fan 51 is avoided, and further the heat radiation effect on the condensation part 40 is influenced.

Alternatively, the outdoor unit of the air conditioner includes a receiving space for receiving the second fan 52, and the casing 60, the first fan 51 and the condensing part 40 are disposed above the receiving space. The second fan 52 is used for heat dissipation of the heat exchanger, and the housing 60, the first fan 51 and the condensing portion 40 are disposed above the accommodating space, so that the airflow path of the second fan 52 can be prevented from being affected.

Alternatively, the air inlet 61 and the air outlet 62 are both in a grid shape. Thus, the air flow can flow in and out regularly. Alternatively, the first fan 51 is a small crossflow fan. The small cross flow fan can reduce the space occupation of the air conditioner outdoor unit as much as possible, and can effectively radiate the condensation part 40 of the radiator. The first fan 51 is not a fan for radiating heat from a heat exchanger in the outdoor unit of the air conditioner, but is provided exclusively as a fan for radiating heat from the radiator condensation unit 40.
