Description

Technical Field

[0001] The utility model relates to the field of radiators, in particular to a reinforced liquid-cooled radiator. Background Art

[0002] At present, there are many heat-generating components in electrical appliances, and the heat of these heat-generating components needs to be dissipated in a timely and effective manner. If it cannot be dissipated in a timely and effective manner, it will affect the use effect and service life of the electrical appliances. For example, in the field of electronic devices, in order to control the temperature of electronic components within a suitable temperature range, a radiator is usually fixed on the surface of the electronic components, and the fins on the radiator are used to diffuse the heat outward, thereby reducing the temperature of the electronic components. Or in the field of air conditioners, the frequency converter module plays a role of power conversion and amplification in the entire frequency converter. Due to switching losses and the resistance of the module itself, heat will be generated during its operation, and the larger the corresponding unit power of the frequency converter, the greater the heat generation. If these heats are not dissipated in time, it will affect the module performance and even burn out the module.

[0003] The applicant previously submitted a patent application with a publication number of "CN109640601A" and an invention title of "A Radiator Cooled by a Medium, and an Air Conditioner Frequency Converter and an Electronic Device Having the Radiator"; in the solution, a medium heat exchange channel is directly formed inside the radiator housing, and together with the cooling medium inlet and the cooling medium outlet, the entire heat exchange medium path is formed. When in use, the cooling medium flows into the above heat exchange medium heat exchange channel to take out the heat from the radiator. Compared with the traditional solution of using copper pipes to form the medium channel, this solution omits the copper pipes and the necessary thermal conductive silicone, reducing the cost. And, in contrast, the medium heat exchange channels formed in this solution can be evenly distributed inside the entire radiator housing, and do not need to be limited by the number of copper pipe circuits, so that the entire heat exchange area can be comprehensively covered, improving the heat exchange effect and ensuring uniform heat exchange. However, it is found in practice that the above-mentioned previous application still has room for improvement. Specifically, as the technical solution described in Embodiment 2 of the previous application refers to Figures 7 and 8, the medium heat exchange channel between the cooling medium inlet and the cooling medium outlet is divided into multiple meandering channel segments by a second partition plate, thereby increasing the travel length and travel time of the medium in the medium heat exchange channel, and the heat exchange is more sufficient. However, relatively speaking, there is a temperature stratification phenomenon of the cooling medium in the meandering channel segments, which is not conducive to promoting the heat exchange efficiency. Summary of the Invention

[0004] In order to solve the above problems, the purpose of the utility model is to provide a reinforced liquid-cooled radiator. In this solution, multiple rows of heat exchange fins are used to construct the medium flow chamber into a turbulent flow chamber, so that the cooling medium forms turbulent flow and eddy current, disrupting the temperature stratification of the cooling medium and improving the heat exchange effect.

[0005] To achieve the above object, the present utility model adopts the following technical solutions:

[0006] An enhanced liquid cooling radiator, comprising a radiator core for contacting a heat source for heat exchange; a medium flow chamber is constructed in the radiator core, and a medium inlet and a medium outlet communicating with the medium flow chamber; characterized in that: along the fluid direction from the medium inlet to the medium outlet, multiple rows of heat exchange fins are arranged in a staggered manner in the medium flow chamber, and the heat exchange fins in the following row are arranged between two adjacent heat exchange fins in the upper row or outside the outermost heat exchange fin in the upper row.

[0007] The present utility model adopts the above technical solution, which relates to a liquid cooling radiator. The inside of the radiator core directly forms a medium heat exchange channel, and together with the medium inlet and the medium outlet, forms the entire heat exchange medium path. During use, the cooling medium flows into the above heat exchange medium channel to take out the heat from the radiator.

[0008] On this basis, multiple rows of heat exchange fins are arranged in a staggered manner in the medium flow chamber. Here, the staggered arrangement refers to an arrangement method similar to a matrix arrangement but with a staggered relationship between adjacent two rows. Specifically in this case, the heat exchange fins in the following row are arranged between two adjacent heat exchange fins in the upper row or outside the outermost heat exchange fin in the upper row. In this way, the multiple rows of heat exchange fins construct the medium flow chamber into a turbulent flow chamber, causing the cooling medium to form turbulent flow and eddy current, disrupting the temperature stratification of the cooling medium, and improving the heat exchange effect.

[0009] In a specific implementation, the multiple rows of heat exchange fins include a first fin group row and a second fin group row; along the fluid direction, the first fin group row and the second fin group row are alternately arranged in a staggered manner, and the second fins in the second fin group row are located between two adjacent first fins in the first fin group row in front of it; the first fins in the first fin group row are located between two adjacent second fins in the second fin group row in front of it or outside the outermost second fin.

[0010] In one implementation, the medium flow chamber in the radiator core is a straight chamber, and the medium inlet and the medium outlet are respectively located at both ends of the radiator core.

[0011] In another implementation shown in the figure, the medium flow chamber in the radiator core is a meandering chamber, and the medium flow chamber includes at least two straight chambers and a baffle chamber connecting one end of adjacent two straight chambers; the medium inlet and the medium outlet are respectively located at both ends of the radiator core or on the same side and in different straight chambers; multiple rows of heat exchange fins are arranged in a staggered manner along the fluid direction in each straight chamber. In this solution, the meandering chamber can increase the travel length and travel time of the cooling medium in the medium flow chamber, and the heat exchange is more sufficient.

[0012] Preferably, the baffle chamber is a flow channel directly formed inside the radiator core.

[0013] On this basis, the first opening where the end of the upstream straight chamber communicates with the baffle chamber is constructed to have a gradually decreasing diameter along the fluid direction, and the first opening serves the functions of confluence and collection. The second opening where the beginning of the downstream straight chamber communicates with the baffle chamber is constructed to have a gradually increasing diameter along the fluid direction, and this second opening serves the function of distribution.

[0014] Preferably, the radiator core is constructed by docking two unit plates, and the medium flow chamber is formed on at least one unit plate; a fin plate is arranged inside the medium flow chamber, and multiple rows of heat exchange fins are formed on the fin plate. In this solution, the two unit plates of the radiator core are docked to form the medium flow chamber, and a fin plate is arranged between the two unit plates, and the fin plate is installed in the medium flow chamber. The fin plate in this solution can be separately processed with multiple rows of heat exchange fins arranged in a staggered manner, and the process is simple.

[0015] Preferably, openings or reinforcing ribs are arranged on the heat exchange fins to further improve the heat exchange performance. Description of the Drawings

[0023] As Figure 1 and 2 shown, this embodiment relates to a strengthened liquid-cooled radiator, which includes a radiator core 1 for contacting a heat source for heat exchange. A medium flow chamber 10 is constructed inside the radiator core 1, and a medium inlet 11 and a medium outlet 12 that are in communication with the medium flow chamber 10. The inside of the radiator core 1 directly forms a medium heat exchange chamber, and together with the medium inlet 11 and the medium outlet 12, it constitutes the entire heat exchange medium path. During use, the cooling medium flows into the above-mentioned heat exchange medium chamber to take out the heat from the radiator.

[0024] On this basis, along the fluid direction from the medium inlet 11 to the medium outlet 12, there are multiple rows of heat exchange fins arranged in a staggered manner within the medium flow chamber 10. The heat exchange fins in the following row are arranged between two adjacent heat exchange fins in the upper row or outside the outermost heat exchange fin in the upper row. In this solution, multiple rows of heat exchange fins are arranged in a staggered manner within the medium flow chamber 10. Here, the staggered arrangement refers to an arrangement method similar to a matrix layout but with a staggered relationship between adjacent two rows. Specifically in this case, the heat exchange fins in the following row are arranged between two adjacent heat exchange fins in the upper row or outside the outermost heat exchange fin in the upper row. In this way, the multiple rows of heat exchange fins construct the medium flow chamber 10 into a turbulent flow chamber, causing the cooling medium to form turbulent flow and eddy current, disrupting the temperature stratification of the cooling medium, and enhancing the heat exchange effect.

[0025] In Figure 1 In the specific implementation shown, the multiple rows of heat exchange fins include a first fin group row 21 and a second fin group row 22. Along the fluid direction, the first fin group row 21 and the second fin group row 22 are arranged alternately in a staggered manner. The second fin 220 in the second fin group row 22 is located between two adjacent first fins 210 in the first fin group row 21 in front of it. The first fin 210 in the first fin group row 21 is located between two adjacent second fins 220 in the second fin group row 22 in front of it or outside the outermost second fin 220.

[0026] In an implementation shown in a schematic diagram (not shown), the medium flow chamber 10 in the radiator core 1 is a straight chamber, and the medium inlet 11 and the medium outlet 12 are respectively located at both ends of the radiator core 1.

[0027] In Figure 1 In another implementation shown in [reference], the medium flow chamber 10 in the radiator core 1 is a meandering chamber. The medium flow chamber 10 includes at least two straight chambers 100 and a baffle chamber 101 connecting one end of two adjacent straight chambers 100. The baffle chamber 101 is a flow channel directly formed inside the radiator core 1. The medium inlet 11 and the medium outlet 12 are respectively located at both ends of the radiator core 1 or on the same side and in different straight chambers 100. Each straight chamber 100 has multiple rows of heat exchange fins arranged in a staggered manner along the fluid direction. In this solution, the use of a meandering chamber can increase the travel length and travel time of the cooling medium within the medium flow chamber 10, and the heat exchange is more sufficient. On this basis, the first opening 102 where the end of the upstream straight chamber 100 communicates with the baffle chamber 101 is constructed to gradually decrease in diameter along the fluid direction, and the first opening 102 has the functions of converging and collecting. The second opening 103 where the beginning of the downstream straight chamber 100 communicates with the baffle chamber 101 is constructed to gradually increase in diameter along the fluid direction, and this second opening 103 has the function of distribution.

[0028] In addition, openings or ribs may be provided on the heat exchange fins to further improve the heat exchange performance.

[0029] In the above solution, the radiator core 1 is constructed by docking two unit plates, and the medium flow chamber 10 is formed on at least one unit plate. A fin plate 2 is arranged in the medium flow chamber 10, and multiple rows of heat exchange fins are formed on the fin plate 2. In this solution, the two unit plates of the radiator core 1 are butted to form the medium flow chamber 10, and a fin plate 2 is arranged between the two unit plates. The fin plate 2 is installed in the medium flow chamber 10. In this solution, the fin plate 2 can be separately processed into multiple rows of heat exchange fins arranged in a staggered manner, and the process is simple.

[0030] When the above enhanced liquid-cooled radiator operates, the cooling medium flows into the medium flow chamber 10 from the medium inlet 11 and flows out from the medium outlet 12 after passing through multiple rows of heat exchange fins arranged in a staggered manner. During this process, the multiple rows of heat exchange fins arranged in a staggered manner cause the cooling medium to form turbulence and eddy current, disrupt the temperature stratification of the cooling medium, and improve the heat exchange effect.
