[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0037] The heat dissipation assembly provided in the embodiments of the present application is suitable for dissipating heat of an electric control heating element in a device (for example, an air-cooled water chiller) which has a wind channel structure by itself, and is especially suitable for dissipating heat of a water chiller which comprises a fan and a heat exchanger. The heat exchanger has a heat exchange wind channel, and the fan is located at an air outlet of the heat exchange wind channel. When the fan is started, a negative pressure can be formed in the heat exchange wind channel to introduce air flow with a lower temperature into the heat exchange wind channel and take away heat of a heat exchange medium inside the heat exchanger, so as to realize heat exchange of the heat exchanger. For the convenience of understanding, the heat dissipation assembly provided in the embodiments of the present application will be exemplarily described below by taking the water chiller which comprises the fan and the heat exchanger as an example:

[0038] As shown in FIG. 1, the heat dissipation assembly comprises an electric control heating element 4, an electric control heat dissipation element 5, a flow guide 6, and an electric control box 3. Figures 1-5As shown, the heat dissipation assembly in the embodiment of the present application includes a flow guide 6 for forming a heat dissipation air duct, which is a structural member capable of guiding gas, and can be an additional plate-shaped member or block-shaped member. The flow guide 6 is arranged around an electric control heat dissipation member 5 of the air-cooled chiller, and the electric control heat dissipation member 5 is in heat conduction connection with an electric control heat generating element 4 (such as a frequency converter, etc.) of the air-cooled chiller. It should be noted that the heat dissipation air duct can be entirely formed by the flow guide 6, or can be formed by the flow guide 6 in cooperation with other structural members (such as the electric control box 3) in the chiller. The heat dissipation air duct includes an air inlet 7 and an air outlet 8, wherein the air outlet 8 is in communication with the heat exchange air duct of the heat exchanger 1, that is, the heat dissipation air duct is in communication with the heat exchange air duct of the heat exchanger 1. The specific implementation manner of the communication can be that the heat dissipation air duct formed by the flow guide 6 directly communicates with the heat exchange air duct, that is, the part of the flow guide 6 surrounding the air outlet 8 directly communicates with the part of the heat exchange air duct surrounding the inlet 101 (the inlet 101 in the embodiment of the present application specifically refers to the opening in the heat exchange air duct for communicating with the heat dissipation air duct, and the same below). The heat dissipation airflow (which refers to the airflow for dissipating heat of the electric control heat generating element 4) flowing from the air inlet 7 to the air outlet 8 flows through the electric control heat dissipation member 5, that is, in the flow direction of the heat dissipation airflow, the electric control heat dissipation member 5 is at least partially located between the air inlet 7 and the air outlet 8.

[0039] During the operation of the chiller using the above heat dissipation assembly, the fan 2 will form a negative pressure in the heat exchange air duct of the heat exchanger 1, thereby forming a driving force to make the heat dissipation airflow flow through the air inlet 7 of the heat dissipation air duct to the air outlet 8 and then flow into the heat exchange air duct. Since the heat in the electric control heat generating element 4 will flow to the electric control heat dissipation member 5, and the heat dissipation airflow flowing from the air inlet 7 to the air outlet 8 will flow through the electric control heat generating element 4, in the above process, the heat dissipation airflow can timely take away the heat generated in the electric control heat generating element 4, thereby achieving the purpose of dissipating heat of the electric control heat generating element 4. As described above, the heat dissipation assembly in the present application does not provide a separate heat dissipation fan, but forms a heat dissipation air duct communicating with the heat exchange air duct of the chiller itself by providing the flow guide 6, so as to achieve the heat dissipation of the electric control heat generating element 4. Such a configuration not only reduces the cost, but also effectively avoids the influence of the additional heat dissipation fan on the noise of the chiller as a whole. In addition, under the condition that the heat exchange air duct has the same negative pressure, the arrangement of the flow guide 6 restricts the path of the heat dissipation airflow flowing into the heat exchange air duct, and makes the flow area of the heat dissipation airflow smaller and the flow velocity faster when flowing through the electric control heat dissipation member 5, thereby effectively improving the heat dissipation efficiency.

[0040] As Figure 2As shown, the electrically controlled heat-dissipating member 5 can be a fin-type electrically controlled heat-dissipating member or a phase-change electrically controlled heat-dissipating member, etc., and the type of the electrically controlled heat-dissipating member 5 can be adaptively designed according to the needs in the specific implementation, which is not specifically limited in the present application. The heat-conducting connection between the electrically controlled heat-dissipating member 5 and the electrically controlled heat-generating element 4 can be connected through a heat-conducting member, that is, the part of the electrically controlled heat-generating element 4 dissipating heat is in heat-conducting connection with the heat-conducting member, and at the same time, the part of the electrically controlled heat-dissipating member 5 for absorbing heat is also in heat-conducting connection with the heat-conducting member, so as to indirectly realize the heat-conducting connection between the electrically controlled heat-dissipating member 5 and the electrically controlled heat-generating element 4. In this arrangement, the shape of the heat-conducting member, etc. can be adaptively designed according to the needs, which is more conducive to the layout of the electrically controlled heat-dissipating member 5 and the electrically controlled heat-generating element 4; or the heat-conducting connection between the electrically controlled heat-dissipating member 5 and the electrically controlled heat-generating element 4 can also be realized through the direct connection between the electrically controlled heat-dissipating member 5 and the electrically controlled heat-generating element 4, that is, the part of the electrically controlled heat-dissipating member 5 for absorbing heat is directly in heat-conducting connection with the part of the electrically controlled heat-generating element 4 dissipating heat. In this way, since the heat transfer path is shorter, it is more conducive to the rapid transfer of the heat generated in the electrically controlled heat-generating element 4 to the electrically controlled heat-dissipating member 5, thereby improving the heat dissipation efficiency.

[0041] Further, in some embodiments, the flow guide member 6 is made of a heat-conducting material (such as metal materials such as copper, aluminum, etc., or ceramic materials such as aluminum nitride, aluminum oxide, etc.), and the flow guide member 6 is in heat-conducting connection with the electrically controlled heat-generating element 4 and the heat exchanger 1, that is, the electrically controlled heat-generating element 4 can also transfer heat to the heat exchanger 1 through the flow guide member 6 to improve the heat dissipation efficiency.

[0042] In addition, in some optional embodiments, the electrically controlled heat dissipation member 5 comprises a plurality of heat dissipation fins, which are used to increase the heat dissipation surface (i.e. the surface in the heat dissipation assembly that can dissipate heat) and thus effectively improve the heat dissipation efficiency. The shape, number and size of the heat dissipation fins can be adaptively designed according to the needs in the specific implementation, for example, the shape of the heat dissipation fins can be set as a wave shape or a straight plate shape, etc., the number of the heat dissipation fins can be 10, 12, etc., and the size of the heat dissipation fins can be set as the maximum size allowed by the heat dissipation air duct or slightly smaller. In addition, the adjacent heat dissipation fins can be arranged in parallel or at an angle (e.g. in a figure-eight shape), which is not specifically limited in the embodiments of the present application. However, it is necessary to ensure that the heat dissipation fins of the electrically controlled heat dissipation member 5 cannot block the heat dissipation air duct. In a preferred embodiment, the adjacent heat dissipation fins form a flow channel that guides the heat dissipation airflow from the air inlet 7 to the air outlet 8, i.e. the heat dissipation airflow entering the heat dissipation air duct through the air inlet 7 will enter the gap between the adjacent heat dissipation fins, and under the guidance of the flow channel formed by the gap, flow to the air outlet 8. In this arrangement, on the one hand, the flow of the heat dissipation airflow can be ensured; on the other hand, the heat dissipation airflow can fully contact the heat dissipation surface (i.e. the surface of the heat dissipation fin used for dissipating heat) of each heat dissipation fin during the process of flowing from the air inlet 7 to the air outlet 8, thus helping to improve the heat dissipation efficiency and the uniformity of heat dissipation. Further preferably, the extension direction of the flow channel formed by the adjacent heat dissipation fins is parallel to the direction of the line connecting the air inlet 7 and the air outlet 8. In this way, the flow resistance of the heat dissipation airflow in the heat dissipation air duct is small, which can improve the flow of the heat dissipation airflow and to some extent, help to improve the heat dissipation efficiency.

[0043] Further, in the arrangement direction of the plurality of heat dissipation fins, the size of the first opening of the communication heat dissipation air duct and the heat exchange air duct is greater than or equal to the size of the electrically controlled heat dissipation member 5. The first opening of the communication heat dissipation air duct and the heat exchange air duct mentioned above refers to the unsealed part allowing the heat dissipation airflow to pass, which is formed by the cooperation of the air outlet 8 of the heat dissipation air duct and the inlet 101 of the heat exchange air duct in the assembled state of the flow guide member 6, i.e. the communication state of the heat dissipation air duct and the heat exchange air duct; in some scenarios, when the size of the air outlet 8 of the heat dissipation air duct is equal to the size of the inlet 101 of the heat exchange air duct, and they are arranged opposite to each other, the size of the first opening is equal to the size of the air outlet 8 (or the size of the inlet 101); in other application scenarios, when the air outlet 8 of the heat dissipation air duct is arranged staggered compared to the inlet 101 of the heat exchange air duct, the size of the first opening is smaller than the size of the air outlet 8, and smaller than the size of the inlet 101. In the embodiment, the size of the first opening of the communication heat dissipation air duct and the heat exchange air duct is greater than or equal to the size of the electrically controlled heat dissipation member 5, so that the consistency of the flow resistance of the heat dissipation airflow in any flow channel formed by the adjacent heat dissipation fins is stronger, thereby improving the consistency of the flow rate of the heat dissipation airflow in any flow channel formed by the adjacent heat dissipation fins, and improving the uniformity of heat dissipation. Of course, in some embodiments, when the problem of heat dissipation uniformity caused by the above-mentioned influence does not need to be considered, or when the heat dissipation fins are far away from the air outlet 8 of the heat dissipation air duct, resulting in that the size of the above-mentioned first opening does not affect the flow resistance of the heat dissipation airflow, in the arrangement direction of the plurality of heat dissipation fins, the size of the first opening of the communication heat dissipation air duct and the heat exchange air duct can also be smaller than the size of the electrically controlled heat dissipation member 5.

[0044] Optionally, in some embodiments, the electrically controlled heating element 4 is in thermal conduction connection with the flow guide 6 through the electrically controlled heat dissipation member 5, and in this case, the heat in the electrically controlled heating element 4 can be transferred to the flow guide 6 in the form of heat conduction through the electrically controlled heat dissipation member 5. In an exemplary implementation, the electrically controlled heat dissipation member 5 includes a heat conduction plate and a heat dissipation fin. The heat conduction plate includes a first heat conduction surface and a second heat conduction surface, which are two opposite surfaces of the heat conduction plate. The first heat conduction surface is in thermal conduction connection with the electrically controlled heating element 4, that is, the part of the electrically controlled heating element 4 that can dissipate heat and conduct heat is in abutment with the first heat conduction surface, so that the heat in the electrically controlled heating element 4 can be transferred to the heat conduction plate in the form of heat conduction. The heat dissipation fin is in thermal conduction connection with the second heat conduction surface, so that the heat in the heat conduction plate is transferred to the heat dissipation fin, thereby increasing the heat dissipation area and improving the heat dissipation efficiency. For ease of description, one end of the heat dissipation fin close to the electrically controlled heating element 4 is referred to as the first end, and the other end away from the electrically controlled heating element 4 is referred to as the second end, that is, the end of the heat dissipation fin connected with the second heat conduction surface is the first end, and the end of the heat dissipation fin opposite to the first end is the second end. In this embodiment, the second end of the heat dissipation fin is in thermal conduction connection with the flow guide 6, so that the electrically controlled heat dissipation member 5 is in thermal conduction connection with the flow guide 6, and the flow guide 6 is in thermal conduction connection with the electrically controlled heating element 4.

[0045] Optionally, in some other embodiments, the electrically controlled heating element 4 can also be in thermal conduction connection with the flow guide 6 through a specially designed heat conduction structure (such as a heat conduction plate), or can be directly in thermal conduction connection with the flow guide 6, that is, the part of the electrically controlled heating element 4 that can dissipate heat is directly in abutment with the flow guide 6.

[0046] As shown in Figure 3 In some embodiments, the flow guide 6 includes a body 601 and a connecting portion 602. The body 601 is a main structure of the flow guide 6 that encloses a heat dissipation air duct. The body 601 has a second opening that can form the air inlet 7 and a third opening that can form the air outlet 8. The connecting portion 602 protrudes from the body 601 and is arranged around the third opening to form the air outlet 8. The end of the connecting portion 602 away from the body 601 is in thermal conduction connection with the heat exchanger 1 to realize the connection between the body 601 and the heat exchanger 1. In this arrangement, only the end of the connecting portion 602 away from the body 601 is in abutment with the heat exchanger 1, and the abutment area is small, which is more conducive to ensuring the sealing performance of the connection position.

[0047] In addition, it should be noted that the body 601 and the connecting portion 602 can be integrally formed, or the body 601 and the connecting portion 602 can be two independent structures that are sealingly connected. The present application does not make a specific limitation on this.

[0048] Further, as shown in Figure 3As shown, the air inlet 7 and the air outlet 8 are located on opposite sides of the electrically controlled heating element 4 in a direction parallel to the flow direction of the heat dissipation airflow. That is, the electrically controlled heating element 4 is located between the air inlet 7 and the air outlet 8 in the direction parallel to the flow direction of the heat dissipation airflow. In this way, the heat dissipation airflow flows through a larger area of the surface of the electrically controlled heating element 4 and / or the surface of the electrically controlled heat dissipation member 5 during the process of flowing from the air inlet 7 to the air outlet 8, thereby more favorably improving the heat dissipation efficiency.

[0049] In addition, the number of air inlets 7 and air outlets 8 is not specifically limited in the specific implementation of the present application. For example, the number of air inlets 7 can be one, two, or three, and / or the number of air outlets 8 can be one, two, or three. In addition, the flow area of the heat dissipation airflow at the air inlet 7 and the air outlet 8 can be adaptively designed according to actual needs, provided that the heat dissipation airflow flowing through the heat dissipation air duct can effectively reduce the temperature of the electrically controlled heating element 4, and at the same time, it is necessary to ensure that it will not have a great impact on the heat exchange of the heat exchanger 1.

[0050] Based on the above heat dissipation assembly, the present application further provides a water chiller, which comprises the electrically controlled heating element 4, the above heat dissipation assembly, the heat exchanger 1, and the fan 2. It should be noted that since the water chiller has the above heat dissipation assembly, the beneficial effects of the water chiller brought by the heat dissipation assembly are described above and will not be repeated here.

[0051] Further, the heat exchanger 1 has a heat exchange air duct, and an opening (which is the inlet 101 of the heat exchange air duct described above) is arranged on the side wall of the heat exchanger 1 to communicate with the heat dissipation air duct in the heat dissipation assembly, and the fan 2 is arranged at the air outlet 8 of the heat exchange air duct. During use of the water chiller, the fan 2 is started to form a negative pressure in the heat exchange air duct of the heat exchanger 1, thereby introducing the gas with a lower temperature outside into the heat exchange air duct. During this process, since the heat exchange air duct is communicated with the heat dissipation air duct, the heat dissipation air duct becomes a path for the gas with a lower temperature outside to enter the heat exchange air duct. The airflow can carry away the heat in the heat dissipation member during the process of flowing through the electrically controlled heating element 4, thereby achieving the cooling of the electrically controlled heating element 4.

[0052] Further, in some embodiments, the water chiller comprises an electric control box 3, and the electrically controlled heating element 4 in the water chiller is a frequency converter, the frequency converter is electrically connected with the electric control box 3 and is arranged between the electric control box 3 and the heat exchanger 1, and the side wall of the electric control box 3 close to the frequency converter cooperates with the flow guide 6 in the heat dissipation assembly to form the heat dissipation air duct. Specifically, as shown in FIG. 6, the electric control box 3 is arranged on the side wall of the heat exchanger 1, and the frequency converter is arranged in the electric control box 3. Figure 3As shown, in this embodiment, the flow guide 6 comprises a body 601 and a connecting portion 602, wherein the body 601 is a groove formed by bending a plate-shaped member, one end of the groove opposite to the bottom wall is connected to the side wall of the electric control box 3, one side wall of the groove is opened to form the air inlet 7, the bottom wall of the groove is opened away from the air inlet 7, and the connecting portion 602 is fixed to the body 601 around the opening to form the air outlet 8, and the connecting portion 602 protrudes the body 601 away from the electric control box 3 to facilitate connection with the side wall of the heat exchanger 1.

[0053] Further, the heat dissipation assembly is arranged on the side of the heat exchanger 1, so that the heat dissipation air duct in the heat dissipation assembly is more convenient to communicate with the heat exchange air duct in the heat exchanger 1.
