Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically a heat dissipation module with multiple radiators. Background Technology

[0002] A radiator is a device that dissipates the heat generated by equipment during operation into the surrounding environment through heat conduction, convection, or radiation. Radiators play a role in reducing equipment temperature and maintaining stable operation, and are widely used in electronics, automobiles, machinery and other fields.

[0003] Chinese Patent Publication CN 204119718 U discloses a heat dissipation module (1), which is a multi-layer sandwich structure. The heat dissipation module (1) has at least one layer of graphite heat dissipation sheet (2) in the middle. The graphite heat dissipation sheet (2) has a first side and a second side. The first side of the heat dissipation module (1) has a single-sided thermally conductive tape (100) or at least one double-sided thermally conductive tape (101). The second side of the graphite heat dissipation sheet (2) has at least one double-sided thermally conductive tape (101).

[0004] The aforementioned heat dissipation module uses a single heat sink. Although the heat dissipation effect is improved by using a different material for the heat sink, the heat dissipation capacity of a single heat sink is relatively low. Furthermore, the heat source being concentrated on a single heat sink can lead to excessively high local temperatures. This not only fails to achieve rapid cooling but also easily causes components near the heat sink to be damaged by high temperatures. Utility Model Content

[0005] The purpose of this utility model is to provide a heat dissipation module with multiple heat sinks. By setting multiple heat sinks, the heat can be distributed and the local temperature can be prevented from being too high. In addition, a cooling fan can be installed to further improve the heat dissipation effect, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat dissipation module with multiple heat sinks includes a first heat sink, a second heat sink is provided above the first heat sink for heat dissipation, and both the first heat sink and the second heat sink are located inside the heat exchange plate.

[0008] The first radiator and the second radiator have the same structure; the first radiator includes an outer frame, on the inner side of which a plurality of vertically arranged heat dissipation fins are uniformly and integrally provided, and the plurality of heat dissipation fins are of the same length; a connecting groove is provided in the middle of the side of the outer frame away from the heat dissipation fins.

[0010] As a further technical solution of this utility model, a third heat sink is provided on the outer side of the plate away from the first heat sink, and the third heat sink has the same structure as the first heat sink; an external protrusion is also integrally provided on the side of the plate that is in contact with the third heat sink.

[0011] As a further technical solution of this utility model, the two inner protrusions are respectively located in the connecting grooves of the first radiator and the second radiator; the outer protrusion is located in the connecting groove of the third radiator.

[0012] As a further technical solution of this utility model, a cooling fan is installed on one outer side of the plate and a mounting base is installed on the other outer side; multiple mounting holes are symmetrically provided at both ends of the plate.

[0013] As a further technical solution of this utility model, the cooling fan includes a fan, which corresponds to the position of the first heat sink and the second heat sink.

[0014] As a further technical solution of this utility model, a protective frame is provided on the outside of the fan, and a base frame is fixedly connected to the bottom of the protective frame, and the bottom of the base frame is in contact with the plate.

[0015] As a further technical solution of this utility model, the base frame is provided with a slot in the middle of both sides, and the two slots are respectively engaged with two connecting brackets, and the ends of the two connecting brackets away from the slots are respectively fixedly connected to the plurality of mounting holes.
