Description

Technical Field

[0001] The utility model relates to the field of radiators, in particular to a 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 greater the power of the corresponding unit 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 creation name of "A Radiator Cooled by a Medium, and an Air Conditioner Frequency Converter and an Electronic Device with the Radiator"; in its 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. In this way, the entire heat exchange area can be fully covered, improving the heat exchange effect and ensuring uniform heat exchange. However, it is found in practice that the above-mentioned prior application still has room for improvement. Specifically, in the technical solution described in Embodiment 2 of the prior application, the medium heat exchange channel between the cooling medium inlet and the cooling medium outlet is divided into multiple circuitous channel segments by the 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 circuitous 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 liquid-cooled radiator. This solution increases the fluid turbulence through the rib strips arranged in an array, improves the heat exchange performance, and minimizes the fluid resistance increased by setting the rib strips.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A liquid cooling radiator includes 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: ribs are arranged in an array in the medium flow chamber, and the ribs are arranged on both sides of the axis of the medium inlet and the axis of the medium outlet; along the fluid direction, the ribs are inclined at an acute angle with respect to the axis of the medium inlet and the axis of the medium outlet.

[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, it constitutes 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, ribs are arranged in an array in the medium flow chamber of this solution. The arrayed ribs can increase fluid turbulence when the cooling fluid passes through, thereby improving the heat exchange performance. And, in this solution, the ribs are arranged on both sides of the axis of the medium inlet and the axis of the medium outlet, and their directions are inclined at an acute angle with respect to the above axes. In this way, the fluid resistance can be reduced when the cooling fluid passes through. That is, this solution increases fluid turbulence through the arrayed ribs, improves the heat exchange performance, and minimizes the fluid resistance increased by setting the ribs.

[0009] On this basis, the ribs are constructed in a trapezoidal shape with a larger width at the lower end and a smaller width at the upper end. In this solution, trapezoidal ribs are adopted. On the one hand, it is convenient for material stamping, and on the other hand, the trapezoidal side wall can promote the generation of turbulence of the fluid in the height direction of the chamber.

[0010] In a further embodiment, at least one of the two side walls of the rib is constructed with fins protruding in the width direction. The setting of the fins can, on the one hand, increase the heat exchange area, and on the other hand, further increase the fluid turbulence.

[0011] In one of the embodiments, the medium flow chamber in the radiator core is a straight chamber, the medium inlet and the medium outlet are respectively located at both ends of the radiator core, and the axes of the medium inlet and the medium outlet coincide; the arrayed ribs are on both sides of the axis.

[0012] In another embodiment, the medium flow chamber in the radiator core is a meandering chamber. The medium flow chamber includes at least two straight chambers and a baffle chamber connecting one end of adjacent straight chambers. The medium inlet and the medium outlet are respectively at both ends or on the same side of the radiator core and are in different straight chambers. In each straight chamber, the ribs are arranged on both sides of the axis of the medium inlet and the axis of the medium outlet. In this solution, the use of a 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.

[0013] On this basis, the baffle chamber is a flow channel directly formed inside the radiator core.

[0014] On this basis, the first opening connecting the end of the upstream straight chamber and the baffle chamber is constructed to gradually decrease in diameter along the fluid direction. The first opening has the functions of confluence and collection. The second opening connecting the beginning of the downstream straight chamber and the baffle chamber is constructed to gradually increase in diameter along the fluid direction. This second opening has the function of distribution.

[0015] Preferably, the radiator core is constructed by butting two unit sheets. The ribs are integrally formed on one or two unit sheets in contact with the heat source. In this solution, the radiator core is formed by butting two unit sheets, which is convenient to manufacture. Integrally forming the ribs on one or two unit sheets in contact with the heat source can directly participate in heat exchange through the ribs, increasing the heat exchange area.

[0016] In a specific embodiment, the unit sheet is stamped inward to obtain ribs protruding into the medium flow chamber. Description of the Drawings

[0024] Such as Figure 1 and 2As shown, this embodiment relates to a liquid-cooled radiator, including a radiator core 1 for contacting a heat source for heat exchange. A medium flow chamber 10 is constructed inside the radiator core 1, as well as a medium inlet 11 and a medium outlet 12 that communicate with the medium flow chamber 10. Ribs 2 are arranged in an array inside the medium flow chamber 10, and the ribs 2 are arranged on both sides of the axes of the medium inlet 11 and the medium outlet 12. Along the fluid direction, the ribs 2 are inclined at an acute angle with respect to the axes of the medium inlet 11 and the medium outlet 12. The inside of the radiator core 1 directly forms a medium heat exchange channel, which together with the medium inlet 11 and the medium outlet 12 constitutes the entire heat exchange medium path. During use, the cooling medium flows into the above-mentioned heat exchange medium channel to carry out the heat out of the radiator.

[0025] On this basis, in this solution, ribs 2 are arranged in an array inside the medium flow chamber 10. By the ribs 2 arranged in an array, the fluid turbulence can be increased when the cooling fluid passes through, improving the heat exchange performance. Moreover, in this solution, the ribs 2 are arranged on both sides of the axes of the medium inlet 11 and the medium outlet 12, and their directions are inclined at an acute angle with respect to the above axes. In this way, the fluid resistance can be reduced when the cooling fluid passes through. That is, this solution increases the fluid turbulence through the ribs 2 arranged in an array, improves the heat exchange performance, and minimizes the fluid resistance increased by setting the ribs 2.

[0026] As Figure 2 shown, the ribs 2 are constructed in a trapezoidal shape with a larger width at the lower end and a smaller width at the upper end. In this solution, the trapezoidal-shaped ribs 2 are adopted. On the one hand, it is convenient for material stamping, and on the other hand, the trapezoidal side wall surface can promote the generation of fluid turbulence in the height direction of the chamber. In a further embodiment, at least one of the two side walls of the ribs 2 is constructed with fins 3 protruding in the width direction. The setting of the fins 3 can, on the one hand, increase the heat exchange area, and on the other hand, further increase the fluid turbulence.

The medium inlet 11 and the medium outlet 12 are respectively at both ends or on the same side of the radiator core 1 and are in different straight chambers 100. In each straight chamber 100, the rib strips 2 are arranged on both sides of the axes of the medium inlet 11 and the medium outlet 12. In this solution, the use of a meandering chamber can increase the travel length and travel time of the cooling medium in the medium flow chamber 10, and the heat exchange is more sufficient. On this basis, the baffle chamber 101 is a flow channel directly formed inside the radiator core 1. The first opening 103 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 103 has the functions of converging and collecting. The second opening 104 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 104 has the function of distribution.
