Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit board heat sinks, in particular to a PCBA board heat sink component. Background Art

[0002] Printed circuit boards, also known as printed circuit boards, often abbreviated as PCB, are important electronic components. They are the support for electronic components and the provider of circuit connections for electronic components. There are many electronic components distributed on printed circuit boards, which will generate a lot of heat during use and require timely heat dissipation treatment.

[0003] The existing announcement number is CN216820498U, and its name is a heat dissipation structure for PCBA boards, which includes a base plate, a conductive sheet fixedly mounted on the top of the base plate, connecting columns located at the four corners of the conductive sheet fixedly mounted on the top of the base plate, a conductive seat fixedly mounted on the top of the conductive sheet, a heat exchange copper tube fixedly mounted on the top of the conductive seat, a circulation copper tube fixedly mounted on the top of the heat exchange copper tube, a small circulation pump connected to the interior of the circulation copper tube, a circulation fan fixedly mounted on the top of the circulation copper tube, a fixing assembly fixedly mounted on the top of the connecting column, two liquid inlet pipes connected to the top of the conduction seat, and a sealing cap threadedly connected to the outer side of the liquid inlet pipe. The heat dissipation structure has the advantages of conveniently dissipating heat through a liquid conductive medium while having a better heat dissipation effect, and solves the problem that most existing heat dissipation mechanisms for PCBA boards have the advantage of being easy to install, but for the conductive medium at the cooling part, a colloidal medium is usually required, otherwise it is easy to cause the flow of the heat conductive medium to cause a short circuit in the PCB board, and thus cannot be used when a better liquid heat conductive medium is required.

[0004] However, when the PCBA board is dissipated heat, a heat dissipation component is arranged on the upper part of the substrate. This heat dissipation method can only dissipate heat on one side of the PCBA board. The heat dissipation amount on one side is limited, and it is impossible to form double-sided heat dissipation for the PCBA board, which affects the heat dissipation effect of the PCBA board. Utility Model Content

[0005] The utility model solves the problems in the related art and proposes a PCBA board heat dissipation component.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions: a PCBA board heat dissipation component, including a mounting part and a circulation part, two mounting parts are horizontally symmetrically arranged, the mounting part includes a mounting box, a support frame is horizontally fixed on the side of the inner wall of the mounting box close to the open end, and an intake fan is horizontally passed through and fixed at both ends of the mounting box, a PCBA board is horizontally arranged between the support frames between the two mounting parts, and cooling parts are respectively passed through and fixed at both ends of the mounting box, the cooling part includes a cooling frame box, the vertical end faces of the cooling frame box are symmetrically opened on both sides, and one end of the cooling frame box is passed through and fixed on the outer end face of the mounting box, and the interior of the cooling frame box is symmetrically passed through and a liquid distribution box is fixed on the front and rear end faces, the circulation part includes a liquid separation box, and two liquid separation boxes are symmetrically arranged, and the outer walls of the two liquid separation boxes are connected and fixed with circulation pipes, and the circulation pipes on the two liquid separation boxes are respectively connected and fixed in the liquid distribution boxes of the two mounting parts, and a circulation pump is connected and fixed on the circulation pipe.

[0007] As a preferred solution, a plurality of liquid separation tubes are horizontally connected and fixed between the two liquid separation boxes, and a plurality of heat conducting sheets are horizontally connected and fixed on the plurality of liquid separation tubes.

[0008] As a preferred solution, bottom plates are horizontally fixed on the bottom surfaces of the two liquid separation boxes, and a cooling fan is fixed through the bottom plates.

[0009] As a preferred solution, screw hole plates are horizontally fixed to both the front and rear sides of the installation box, and the screw hole plates adjacent to the installation box in the two mounting parts of the screw hole plates are fixed and assembled by bolts.

[0010] As a preferred solution, a plurality of liquid distribution pipes are fixedly connected horizontally between the liquid distribution boxes on the front and rear sides of the cooling frame, and a plurality of cooling plates are fixedly passed through the plurality of liquid distribution pipes.

[0011] As a preferred solution, a filter is fixed to the other open end of the cooling frame.

[0012] As a preferred solution, exhaust grooves are provided on both the front and rear sides of the bottom of the installation box, and meshes are fixed in the exhaust grooves of the installation box.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: during use, the PCBA board is horizontally installed between the mounting boxes of the two mounting parts. When the PCBA board is subjected to heat dissipation treatment, the air intake fans at both ends of the mounting box are started to drive external air into the cooling frame from one end. The air contacts the liquid distribution pipes between the liquid distribution boxes, and the incoming air is cooled. The air then enters the mounting box and directly contacts the PCBA board, while cooling both sides of the PCBA board, effectively ensuring the cooling effect of the PCBA board.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0023] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
