DETAILED DESCRIPTION

[0036] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0037] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to "inside" and "outside" relative to the corresponding component's own contour. In addition, the terms "first", "second", "third", "fourth", etc. used in the present disclosure are to distinguish one element from another and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0038] The present disclosure provides a heat sink, referring to Figures 1 to 3 As shown in the figure, the radiator includes: a mounting base 1; a heat transfer element 2, fixed to the mounting base 1; a sealing cover 3, which is covered on the heat transfer element 2 and connected to the mounting base 1; a fan 4, mounted on the sealing cover 3; and an air guide shell 5, the air guide shell 5 is formed with an air guide space and an air inlet 52 and an air outlet 53 connected to the air guide space, the air guide shell 5 is arranged on the sealing cover 3 and is connected to the sealing cover 3, and is used for directional outlet of the air flow, and the heat transfer element 2 is located in the enclosed space surrounded by the mounting base 1, the sealing cover 3, the fan 4 and the air guide shell 5.

[0039] Through the above technical scheme, in the radiator provided by the present invention, a sealing cover 3 is provided on the heat transfer element 2, a fan 4 and an air guide shell 5 which is connected with the sealing cover 3 and is used for directionally guiding the wind flow are provided on the sealing cover 3, and an air guide space and an air inlet 52 and an air outlet 53 which are connected with the air guide space are formed on the air guide shell 5, and the heat transfer element 2 is arranged in the surrounding space surrounded by the mounting seat 1, the sealing cover 3, the fan 4 and the air guide shell 5. In this way, when the fan 4 is turned on, the external cold air will be sucked in and the wind flow will be generated through the blades of the fan 4. These wind flows pass through the surrounding space and enter the wind guide space through the air inlet 52 under the action of the air guide shell 5, and are finally discharged from the air outlet 53 on the air guide shell 5. In the above process, since the cold airflow will generate heat exchange with the hot heat transfer element 2 in the enclosed space to reduce the temperature of the heat transfer element 2 and obtain hot airflow, and finally make these hot airflows be discharged in a direction through the exhaust port 53 on the air guide shell 5, therefore, the radiator can not only reduce the temperature of the heat transfer element 2 to achieve the heat dissipation function, but also due to the setting of the air guide shell 5, these hot airflows can be discharged in a direction through the path formed by the air guide shell 5, which also helps to improve the heat dissipation efficiency of the heat transfer element 2.

[0040] It should be noted that, in the above process, in order to further improve the heat dissipation efficiency of the heat transfer element 2, a sealed connection can be set between the mounting base 1, the sealing cover 3, the fan 4 and the air guide shell 5, so that the wind can be more reliably discharged from the exhaust port 53 on the air guide shell 5. Here, the sealed connection between these structures can be achieved in any suitable manner, and the present disclosure is not limited to this. For example, the sealed connection between the above structures can be achieved by tightening bolts in combination with sealant.

[0041] In the exemplary embodiment provided by the present disclosure, the air guide housing 5 and the fan 4 can be arranged in any suitable manner, and the present disclosure does not limit this. Figure 1 As shown in the figure, in order to increase the flow rate of the wind flow so as to improve the heat dissipation efficiency of the heat transfer element 2, the air guide shell 5 and the fan 4 can be arranged opposite to each other. In this way, since the air guide shell 5 is arranged on the opposite side of the fan 4, it is more conducive to the smooth outflow of the wind flow, thereby further improving the heat dissipation efficiency of the heat transfer element 2.

[0042] In the exemplary embodiment provided by the present disclosure, the air outlet 53 and the mounting base 1 can be arranged in any suitable manner, and the present disclosure does not limit this. Figure 1 As shown in the figure, since the part to be cooled (not shown in the figure) is arranged on the side of the mounting base 1 away from the heat transfer part 2, the air flow can be discharged toward the side away from the part to be cooled by arranging the exhaust port 53 relative to the mounting base 1, so as to further improve the heat dissipation efficiency of the radiator.

[0043] In the exemplary embodiments provided in the present disclosure, the air guide housing 5 can be implemented in any suitable manner, and the present disclosure does not limit this. Figure 3 As shown in , the air guide housing 5 may include a first side wall 511, a second side wall 512, a third side wall 513 and a fourth side wall 514, and the first side wall 511, the second side wall 512, the third side wall 513 and the fourth side wall 514 are collectively arranged to form a channel body 51 having a first opening 521 and a second opening 531, wherein the first opening 521 is used as an air inlet 52, and the second opening 531 is used as an air outlet 53. Here, the first side wall 511, the second side wall 512, the third side wall 513 and the fourth side wall 514 may be enclosed into the channel body 51 in any suitable manner, and the present disclosure is not limited thereto. Exemplarily, the first side wall 511, the second side wall 512, the third side wall 513 and the fourth side wall 514 may be sequentially connected to enclose the channel body 51.

[0044] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 1 As shown in the figure, the third side wall 513 is located on the side of the channel body 51 away from the heat transfer element 2, and at least a portion of the third side wall 513 is constructed as an arc-shaped wall to guide the wind flow toward the exhaust port 53. In this way, since at least a portion of the third side wall 513 is constructed as an arc-shaped wall, when the wind flow passes through the surrounding space and flows into the air guide shell 5, the setting of the arc-shaped wall can reduce the flow resistance of the wind flow, so that the wind flow can flow out smoothly through the channel body 51, thereby further improving the heat dissipation efficiency.

[0045] It should be noted that, in the above embodiment, "at least part of the third side wall 513 is constructed as an arc-shaped wall" means that the third side wall 513 can be entirely constructed as an arc-shaped wall, or part of it can be constructed as an arc-shaped wall, wherein, when a part of the third side wall 513 is constructed as an arc-shaped wall, this part of the side wall constructed as the arc-shaped wall is used to contact the wind flow that has just entered the channel main body 51 through the air inlet 52, so as to guide the wind flow to flow toward the exhaust port 53.

[0046] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 3 As shown in the figure, in order to improve the structural strength of the air guide shell 5, the first side wall 511 and the third side wall 513 can be arranged to face the fan 4, and the radiator also includes a reinforcing rib 6, and the reinforcing rib 6 is connected between the first side wall 511 and the third side wall 513. Here, the number of reinforcing ribs 6 can be flexibly arranged according to actual conditions, and the present disclosure does not limit this. Exemplarily, three reinforcing ribs 6 as shown in the figure can be set, and the three reinforcing ribs 6 are evenly spaced and arranged along the direction perpendicular to the line connecting the first side wall 511 and the third side wall 513.

[0047] In the exemplary embodiments provided by the present disclosure, the radiator can be applied to a variety of scenarios, such as household appliances, vehicles, and industrial equipment. For example, household appliances can be household refrigerators, washing machines, etc., vehicles can be cars, electric vehicles, etc., and industrial equipment can be various types of mechanical processing equipment and other equipment involved in the production process. In addition, the radiator can also be applied to vehicle refrigerators. When the radiator is applied to a vehicle refrigerator in a vehicle, the radiator can be installed on the inner side of the center console of the vehicle, and the air outlet of the center console is opposite to the exhaust port 53 of the radiator, so that the airflow discharged from the exhaust port 53 can be discharged through the air outlet of the center console. Therefore, in order to avoid the presence of a gap between the wall of the center console and the air guide shell 5 during installation, which causes the airflow to flow back into the air guide shell 5 and affect the exhaust effect, and ultimately affect the heat dissipation efficiency, the radiator can be provided to also include a sealing ring 7, reference Figure 3 and Figure 4 As shown in , the sealing ring 7 has a sealing surface 71 and is provided with a sealing groove 711. The sealing groove 711 is recessed from the sealing surface 71 toward the inside of the sealing ring 7. The sealing ring 7 is arranged at the exhaust port 53, and the air guide shell 5 is embedded in the sealing groove 711. In this way, the sealing ring 7 can be used to reliably seal the gap between the wall surface of the center console and the air guide shell 5, thereby ensuring that the airflow can pass through the exhaust port 53 of the radiator and be smoothly discharged from the air outlet of the center console.

[0048] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 and Figure 6 As shown in, the radiator may also include a cooling plate 9 electrically connected to an external power supply, and the cooling plate 9 is used to be arranged between the part to be cooled and the mounting seat 1 and to contact the part to be cooled and the mounting seat 1 respectively, wherein, since the cooling plate 9 utilizes the Peltier effect of the semiconductor material, that is, when direct current passes through an electric couple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the electric couple to achieve the purpose of cooling, therefore, the heat absorbing surface of the cooling plate 9 is in contact with the part to be cooled, and the heat releasing surface is in contact with the mounting seat 1, so as to achieve the cooling operation of the part to be cooled by the heat absorbing effect of the heat absorbing surface, and at the same time, the heat generated in the cooling process is transferred to the heat transfer part 2 through the mounting seat 1 through the heat releasing effect of the heat releasing surface, and finally discharged through the air guide shell 5 on the radiator.

[0050] In the exemplary embodiments provided by the present disclosure, the first mounting portion 83 can be implemented in any suitable manner, and the present disclosure is not limited thereto.

In this way, the flow path of the airflow from the fan 4 is the same as the direction of the gap between two adjacent heat transfer elements 2, which is more conducive to the airflow passing through the gaps between these heat transfer elements 2 and smoothly bringing out the heat.

[0052] The heat transfer element 2 and the mounting seat 1 may be fixed in any suitable manner, and the present disclosure does not limit this. Optionally, in order to facilitate manufacturing and assembly and reduce manufacturing costs, the heat transfer element 2 and the mounting seat 1 may be integrally formed.
