Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation, and in particular to a radiator, an electrical box assembly and an air conditioner. Background Art

[0002] With the development of air conditioners, the size of air conditioners is getting smaller and smaller, but the power is getting bigger and bigger. The power components in the electrical box generate serious heat, which causes the temperature rise of the electrical box to be higher and higher, directly affecting the service life of the electrical components.

[0003] At present, the air conditioning industry generally adopts refrigerant heat dissipation technology, such as Figure 1 As shown, Figure 1 It is a structural schematic diagram of a refrigerant radiator in the prior art; the prior refrigerant radiator includes an aluminum block 200 and a copper tube 300 passing through the aluminum block 200, the copper tube 300 is coiled in the aluminum block 200 and refrigerant flows in the copper tube, wherein the aluminum block 200 is in contact with the electrical box, and local heat is dissipated for the IPM module of the electrical box or the components with high heat generation to be dissipated.

[0004] The applicant has found that the prior art has at least the following technical problems:

[0005] 1. Due to the copper tube processing reasons, the existing copper tube radiator usually only forms a coiled flow channel on the aluminum block, and the flow channel formed in the copper tube is difficult to fit completely with the aluminum block, and there is a gap. The heat of the heat dissipation component needs to be transferred to the aluminum block first, and then transferred from the aluminum block to the refrigerant in the copper tube, and the refrigerant takes away the heat; therefore, the heat exchange area between the refrigerant and the heat dissipation component is small and the heat transfer efficiency is low.

[0006] 2. Affected by the internal temperature of the electrical box, other components that cannot directly contact the refrigerant heat dissipation module still generate high temperatures. The usual method is to open the heat dissipation windows of the electrical box to dissipate heat to reduce the temperature of other components. However, the above heat dissipation structure and heat dissipation method destroy the sealing of the electrical box, which has an adverse effect on insect prevention, dust prevention, water prevention and moisture prevention.

DETAILED DESCRIPTION

[0041] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0043] The embodiments of the present invention provide a radiator, an electrical box assembly and an air conditioner which can increase the heat exchange area between the refrigerant in the refrigerant flow channel and the heat element to be cooled and improve the heat exchange efficiency.

[0044] Combine the following Figure 1-Figure 8 The technical solution provided by the present invention is described in more detail.

[0045] Figure 1 It is a schematic diagram of a refrigerant radiator in the prior art; a copper tube is passed through the aluminum block of the existing refrigerant radiator. Due to manufacturing problems, there is a gap between the copper tube 300 and the aluminum block 200, and the refrigerant in the copper tube 300 is difficult to directly contact the heat element 5 to be cooled. The heat exchange area between the refrigerant and the heat element 5 to be cooled is small and the heat exchange efficiency is low.

[0046] like Figure 2-Figure 7 As shown, an embodiment of the present invention provides a radiator, including a main body 100 for contacting a heat dissipation component 5, wherein: a refrigerant inlet 21 and a refrigerant outlet 22 are present on the main body 100, a refrigerant flow channel 4 is constructed inside the main body 100, the number of the refrigerant flow channels 4 is one or more than two, the inlets of all the refrigerant flow channels 4 are connected to the refrigerant inlet 21, and the outlets of all the refrigerant flow channels 4 are connected to the refrigerant outlet 22.

[0047] The radiator of this embodiment directly constructs the refrigerant flow channel 4 on the radiator body 100. There is no gap between the refrigerant flow channel 4 and the body 100, and there is no heat transfer gap, which increases the heat exchange area; and it is convenient to form a larger number of refrigerant flow channels 4 on the body 100 of the same size; when there are more than two refrigerant flow channels 4, the refrigerant can enter through multiple refrigerant flow channels at the same time, which is beneficial to the uniformity of heat exchange; and under the conditions of the same size of the body 100 and the same flow rate of refrigerant, the heat exchange area between the refrigerant in the refrigerant flow channel 4 and the heat element 5 to be cooled can be increased, and the heat exchange efficiency can be improved.

[0048] As an alternative embodiment, see Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the body 100 includes a first plate body 1 and a second plate body 2 connected to each other, and a groove 32 is configured on the first plate body 1 and / or the second plate body 2. The groove 32 on one of the first plate body 1 or the second plate body 2 is sealed with the plate surface or the groove 32 on the other plate body to form a refrigerant flow channel 4. In other words, the refrigerant flow channel 4 is formed by splicing two grooves 32 arranged on the first plate body 1 and the second plate body 2, or by sealing the groove 32 on one plate body with the plate surface on the other plate body. Preferably, see Figure 3-Figure 5 As shown, the first plate body 1 and the second plate body 2 are configured with grooves 32 , and the grooves 32 located on the two plates are sealed to form the above-mentioned refrigerant flow channel 4 .

[0049] The refrigerant flow channel 4 is formed by splicing the grooves 32 on the first plate body 1 and the second plate body 2. Compared with the structure in which the grooves 32 and the plate surface are spliced ​​to form the refrigerant flow channel 4, the refrigerant flow resistance can be reduced, so that the refrigerant in the refrigerant flow channel 4 flows more smoothly.

[0050] As an alternative embodiment, see Figure 6 and Figure 7 As shown, in this embodiment, there is a connecting plane 36 between adjacent grooves 32, and the connecting planes 36 on the first plate body 1 and the second plate body 2 are fitted and fixed so that the corresponding grooves 32 on the two plates are sealed to form the refrigerant flow channel 4. Preferably, in this embodiment, the grooves 32 on the first plate body 1 and the second plate body 2 have the same structure, and all the refrigerant flow channels 4 are evenly spaced, and the connecting planes 36 on the two plates are fixed by welding to ensure the sealing performance of the refrigerant flow channel 4.

[0051] As an optional embodiment, a plane on one side of the main body 100 is used to contact the heat element to be cooled 5, and a first pipe joint 23 for connecting to the refrigerant inlet pipe and a second pipe joint 24 for connecting to the refrigerant outlet pipe are installed on a plane on the other side of the main body 100; specifically, one side of the plane of the first plate body 1 is used to contact the heat element to be cooled 5, and one side of the plane of the second plate body 2 is installed with the above-mentioned first pipe joint 23 and second pipe joint 24; the first pipe joint 23 is connected to the refrigerant inlet 21, and the second pipe joint 24 is connected to the refrigerant outlet 22.

[0052] In the above structure, the heat dissipation element 5 and all the pipe joints connected to the system refrigerant pipeline are distributed on both sides of the body 100, so as to prevent the refrigerant pipeline connection from affecting the installation of the heat dissipation element 5, and ensure that there is sufficient heat exchange position for the heat dissipation element 5 on the body 100. The first pipe joint 23 and the second pipe joint 24 are arranged on the body 100, so as to facilitate the connection with the refrigerant pipeline in the air-conditioning system, facilitate installation, and allow the refrigerant to flow smoothly in the radiator body 100 to exchange heat with the heat dissipation element 5 in the air-conditioning system.

[0053] See also Figure 1-Figure 5As shown, the radiator body 100 of this embodiment is a rectangular plate structure, and the refrigerant flow channel 4 extends along the length direction of the body 100 and is evenly arranged along the width direction of the body 100, or the refrigerant flow channel 4 extends along the width direction of the body 100 and is evenly arranged along the length direction of the body 100; so that the refrigerant flow channel 4 is evenly distributed on the entire body 100, the area of ​​the body 100 is fully utilized, the heat exchange area between the refrigerant and the heat dissipation component 5 is increased, and the refrigerant passes through the radiator evenly.

[0054] In order to make the structure compact and facilitate the connection between the refrigerant inlet pipe and the refrigerant outlet pipe, as an optional implementation, see Figure 2 , Figure 3 and Figure 5 As shown, the first pipe joint 23 and the second pipe joint 24 are located at the same end of the body 100, that is, the refrigerant inlet 21 and the refrigerant outlet 22 are located at the same end of the body 100. The above structure can reduce the span between the refrigerant inlet pipe and the refrigerant outlet pipe, and facilitate the connection between the corresponding pipe joint and the system refrigerant pipeline.

[0055] In order to reduce the flow resistance of the refrigerant in the refrigerant flow channel 4, as an optional embodiment, the radial cross section of the refrigerant flow channel 4 is semicircular and / or circular and / or elliptical. Figure 7 As shown, the radial cross-section of the groove formed on the first plate body 1 and the second plate body 2 is semicircular, and the grooves on both sides are spliced ​​to form a refrigerant flow channel 4 with a circular radial cross-section, which can reduce flow dead angles and make the refrigerant flow more smoothly in the refrigerant flow channel 4.

[0056] In order to further improve the uniformity of refrigerant distribution, so that the refrigerant passes through the radiator evenly and the heat exchange at each part of the radiator is more uniform, as an optional implementation method, see Figure 4 and Figure 5 As shown, the main body 100 also has a refrigerant diversion area 31 and / or a refrigerant confluence area 35 with an internal cavity structure, wherein: the refrigerant diversion area 31 connects the refrigerant inlet 21 and the inlets of all refrigerant flow channels 4, and the refrigerant confluence area 35 connects the outlets of all refrigerant flow channels 4 and the refrigerant outlet 22.

[0057] The refrigerant entering the refrigerant inlet 21 first flows into the refrigerant diversion area 31, and then is distributed to all refrigerant pipelines by the refrigerant diversion area 31, so that the refrigerant flow rate entering each refrigerant flow channel 4 is more uniform, the refrigerant distribution is more uniform, and the heat exchange between the radiator and the heat dissipation element 5 is more uniform. Similarly, the refrigerant in all refrigerant flow channels 4 first flows into the refrigerant confluence area 35 and then flows back to the system refrigerant pipeline together, which is also beneficial to the uniformity of heat exchange of the system refrigerant.

[0058] The refrigerant inlet 21 may be located on the refrigerant diversion area 31, or may not be located on the refrigerant diversion area 31. Figure 5 As shown, the refrigerant inlet 21 is located on the refrigerant diversion area 31, the refrigerant diversion area 31 has a curved side wall, and the inlets of all refrigerant flow channels 4 are connected to the same curved side wall of the refrigerant diversion area 31; and / or, the refrigerant outlet 22 is located on the refrigerant confluence area 35, the refrigerant confluence area 35 has a curved side wall, and the outlets of all refrigerant flow channels 4 are connected to the same curved side wall of the refrigerant confluence area 35.

[0059] In this embodiment, the refrigerant diversion area 31 and the refrigerant confluence area 35 have the same structure, and both have the above-mentioned arc-shaped side walls. The above-mentioned structure enables the refrigerant entering the refrigerant diversion area 31 to be radially distributed to each refrigerant flow channel 4 without flow dead corners, making the refrigerant distribution more uniform. Similarly, the refrigerant flowing out of the refrigerant flow channel 4 can be smoothly converged to the refrigerant outlet 22 in the refrigerant confluence area 35 to prevent the generation of flow dead corners; the distance of the refrigerant flow channel 4 is relatively uniform, the refrigerant distribution is more uniform, the refrigerant flow is more uniform, the heat exchange at various parts of the radiator is more uniform, and the heat dissipation effect is better.

[0060] As an optional implementation, the radial cross-section of the refrigerant diversion area 31 and / or the refrigerant confluence area 35 is one or more of a fan-shaped, fan-shaped ring, and a circle.

[0061] like Figure 4 and Figure 5 The figure shows a refrigerant diversion area 31 and a refrigerant confluence area 35 with a fan-shaped radial cross section, which makes the refrigerant path relatively uniform, facilitates the uniform distribution of the refrigerant entering the body 100, and makes the flow more uniform. The refrigerant diversion area 31 and the refrigerant confluence area 35 of this embodiment are both formed by sealing and splicing the fan-shaped grooves on the first plate body 1 and the second plate body 2. When the first plate body 1 and the second plate body 2 are spliced ​​to form the refrigerant flow channel 4, the fan-shaped grooves on both sides are also spliced ​​to form the above-mentioned refrigerant diversion area 31 and the refrigerant confluence area 35, which is convenient for manufacturing and installation.

[0062] In order to further improve the uniformity of refrigerant distribution, so that the refrigerant passes through the radiator evenly and the heat exchange at each part of the radiator is more uniform, as an optional implementation method, see Figure 4 and Figure 5 As shown, the main body 100 also has a converging and diverting area 33 , which is connected to all the refrigerant flow channels 4 , and is located on the flow path of the refrigerant in all the refrigerant flow channels 4 , and is located between the refrigerant inlet 21 and the refrigerant outlet 22 .

[0063] The refrigerant in the refrigerant flow channel 4 flows into the confluence and diversion area 33 and converges in this area, and then is redistributed to the refrigerant flow channel 4, so that the refrigerant passes through the radiator evenly, and the refrigerant temperature in each refrigerant flow channel 4 is more uniform, thereby improving the uniformity of heat exchange with the heat dissipation element 5 to be cooled, and preventing uneven heat exchange effects in different places due to uneven cooling due to different heat exchange environments during the flow of the refrigerant in each refrigerant flow channel 4.

[0064] As an alternative embodiment, see Figure 4 and Figure 5 As shown, the above-mentioned converging and diverting area 33 is an arc-shaped flow channel, and all the refrigerant flow channels 4 are connected to the same arc-shaped side wall of the converging and diverting area 33; it can prevent the generation of flow dead corners and uneven flow in the process of the refrigerant flowing into or out of the converging and diverting area 33, resulting in uneven heat exchange with the heat dissipation component 5.

[0065] As an alternative embodiment, see Figure 4 and Figure 5 As shown, the converging and diverting area 33 is an arc-shaped flow channel with equal width everywhere; it is convenient to improve the uniformity of the refrigerant redistribution in the converging and diverting area 33, which is beneficial to improve the uniformity of heat exchange between the refrigerant and the heat dissipation element 5 to be cooled, and improve the heat dissipation effect of the radiator.

[0066] As an alternative embodiment, see Figure 4 and Figure 5 As shown, the refrigerant inlet 21 and the refrigerant outlet 22 are located at the first end of the main body 100, and the confluence and diversion area 33 is located at the second end of the main body 100; at this time, the refrigerant flow channel 4 through which the internal refrigerant flows into the confluence and diversion area 33 and the refrigerant flow channel 4 through which the internal refrigerant flows out of the confluence and diversion area 33 are arranged along the width direction of the main body 100; the confluence and diversion area 33 is located in the middle position of the refrigerant flow path, which is convenient for the uniformity of refrigerant distribution and redistribution, and makes the refrigerant outlet 22 and the refrigerant inlet 21 located at the same end of the main body 100, preventing the span between the refrigerant inlet pipe and the refrigerant outlet pipe from being too large. Alternatively, the refrigerant inlet 21 and the refrigerant outlet 22 are respectively located at the two ends of the main body 100. At this time, the confluence and diversion area 33 is located in the middle position of the main body 100, and the refrigerant flow channel 4 through which the internal refrigerant flows into the confluence and diversion area 33 and the refrigerant flow channel 4 through which the internal refrigerant flows out of the confluence and diversion area 33 are arranged along the length direction of the main body 100. At this time, the refrigerant inlet 21 and the refrigerant outlet 22 are respectively located at the two ends of the main body 100.

[0067] In order to further improve the uniformity of refrigerant distribution, as an optional implementation, see Figure 4 and Figure 5As shown, all refrigerant flow channels 4 for the internal refrigerant to flow into the converging and diverging area 33 have the same structure and are evenly distributed along the width or length direction of the body 100; and / or, all refrigerant flow channels 4 for the internal refrigerant to flow out of the converging and diverging area 33 have the same structure and are evenly distributed along the width or length direction of the body 100. In this embodiment, all refrigerant flow channels 4 have the same structure and are evenly distributed, ensuring the uniformity of refrigerant distribution and refrigerant flow.

[0068] In order to further improve the uniformity of refrigerant distribution and make the refrigerant uniformly pass through the entire radiator body 100, as an optional implementation, the number of refrigerant flow channels 4 where the internal refrigerant flows into the confluence and diversion area 33 is equal to the number of refrigerant flow channels 4 where the internal refrigerant flows out of the confluence and diversion area 33. This structure can make the heat exchange area corresponding to the refrigerant flow channel 4 where the internal refrigerant flows into the confluence and diversion area 33 and the heat exchange area corresponding to the refrigerant flow channel 4 where the internal refrigerant flows out of the confluence and diversion area 33 have relatively more uniform cooling capacity, so that the cooling capacity distribution of the entire radiator body 100 is relatively more uniform, which is convenient for uniform heat dissipation.

[0069] For the heat dissipation component 5 with a large heat generation, the refrigerant flow path can be shortened by adjusting the position of the converging and diverting area 33 so as to improve the uniformity of heat exchange.

[0070] For details, see Figure 3-Figure 7 As shown, the first plate body 1 and the second plate body 2 in this embodiment are separated from the refrigerant diversion area 31 and the refrigerant confluence area 35, and the upper refrigerant flow channel 4 and the lower refrigerant flow channel 4 by the intermediate barrier part 34; after passing through the refrigerant diversion area 31, the refrigerant can pass through the upper refrigerant flow channel 4 evenly, and then the upper refrigerant is collected by the arc-shaped confluence and diversion area 33 and then evenly distributed to the refrigerant channel in the lower part, after two distribution processes, it is finally collected in the refrigerant confluence area 35, and participates in the refrigerant circulation through the refrigerant lead-out pipe, and simultaneously takes away the heat, further ensuring that the refrigerant can pass through the radiator body 100 evenly, so that the temperature of each part on the body 100 is uniform, thereby improving the heat dissipation effect.

[0071] In order to ensure that the refrigerant reduces the flow resistance in each refrigerant flow channel 4 and ensures the uniformity of the cooling capacity in each refrigerant flow channel 4, as an optional implementation, see Figure 3-Figure 5 As shown, all the refrigerant flow channels 4 of this embodiment are linear flow channels.

[0072] As an optional embodiment, the lengths of all refrigerant flow channels 4 are equal; the equal-length refrigerant flow channels 4 structure makes the refrigerant resistance along the way consistent, allowing the refrigerant to pass through the radiator body 100 more evenly, facilitating the uniformity of the radiator's heat exchange and improving the heat dissipation effect.

[0073] The present invention also provides an electrical box assembly, see Figure 8As shown, including the above-mentioned heat sink, one or more heat dissipation components 5 are mounted on the main body 100 .

[0074] For example, the high-power heat-generating components on the PCB are closely attached to the mounting surface (the plane side of the first plate body 1) of the radiator body 100 through the heat dissipation grease, and the refrigerant flowing in the refrigerant flow channel 4 can directly contact the heat dissipation component 5 to be dissipated, and there is no heat exchange gap. The refrigerant directly takes away the heat of the components, ensuring that the components work reliably at a reasonable temperature. The heat of other components in the electrical box is radiated into the electrical box, and the radiator then absorbs the heat of the electrical box and takes it away through the flowing refrigerant, achieving the purpose of cooling the entire electrical box.

[0075] The electrical box assembly and air conditioner having the above-mentioned radiator can also increase the heat exchange area between the heat dissipation element 5 on the electrical box and the refrigerant, ensure the sealing of the electrical box, and improve the reliability of the overall components.

[0076] An embodiment of the present invention further provides an air conditioner, comprising the above-mentioned radiator.

[0077] The air conditioner with the above radiator can also dissipate heat from components inside the air conditioner, thus ensuring the reliability of the air conditioner operation.

[0078] In the description of this specification, specific features, structures or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0079] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
