Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile radiators, in particular to a multi-fin aluminum profile radiator. Background Art

[0002] Aluminum profile heat sink is a heat dissipation device that utilizes the excellent thermal conductivity of aluminum profiles. It has the advantages of light weight and good heat dissipation performance.

[0003] At present, the heat dissipation method of aluminum profiles is mainly fin heat dissipation. The ends of multiple groups of fins are open, and the heat is naturally dissipated to the external environment. The way to increase the heat dissipation efficiency is to accelerate the airflow. The fins with openings on the top have poor ability to restrain the airflow, so the heat dissipation efficiency will decrease accordingly. For this reason, we propose a multi-fin aluminum profile radiator. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a multi-fin aluminum profile radiator. The fins with top openings in the currently used aluminum profile radiator have poor airflow restraint capabilities, so the heat dissipation efficiency is reduced.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a multi-fin aluminum profile radiator, comprising an aluminum profile base, the surface of the aluminum profile base is formed with two groups of symmetrical side components, the two groups of side components are respectively formed with side air ducts and intermediate air ducts in cooperation with the aluminum profile base, a main air duct is formed between the ends of the two groups of side components, and the surfaces of the side components and the main air duct are both formed with cooling fins.

[0006] Preferably, the two groups of side members are arranged obliquely, and the edges of the side air ducts and the intermediate air ducts are both designed to be arc-shaped.

[0007] Preferably, the main air duct is designed to be annular, and both ends of the annular main air duct are connected to form an air duct.

[0008] Preferably, the heat dissipation fins are symmetrically arranged with the center of the aluminum profile base as the symmetry axis, and the ends of the heat dissipation fins are designed to be arc-shaped.

[0009] Preferably, an external fixing groove is formed in the middle of the heat dissipation fin, and the bottom of the external fixing groove is designed to be flat.

[0010] Preferably, two groups of thermal conductive paste fixing seats are formed at the bottom end of the aluminum profile base, and grooves are provided inside the two groups of thermal conductive paste fixing seats.

[0011] Preferably, the two groups of grooves cooperate to form a placement space, and the ends of the grooves are designed to be arc-shaped.

[0012] Preferably, a plurality of groups of downward pressing protrusions are formed on the lower portion of the aluminum profile base, and each group of downward pressing protrusions extends downward into the placement space.

[0013] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0014] 1. In the present invention, the two groups of side members are tilted, the edges of the side air duct and the intermediate air duct are both arc-shaped, the main air duct is annular, and the two ends of the annular main air duct are connected to form an air duct. The side air duct, the intermediate air duct and the main air duct all constitute axial air ducts. In the axial air duct, the unidirectional air flow can quickly take away the heat, thereby accelerating the heat dissipation efficiency;

[0015] 2. The lower part of the aluminum profile base is formed with several groups of downward pressing protrusions, and each group of downward pressing protrusions extends downward into the placement space. The thermal conductive strips arranged in the placement space will be squeezed by the downward pressing protrusions to ensure the stability of the thermal conductive paste fitting state, so that the heat of the electronic components can be stably transferred to the aluminum profile base through the thermal conductive paste.

[0021] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0022] Example:

[0023] See also Figure 1 - Figure 4 A multi-fin aluminum profile radiator includes an aluminum profile base 1, two groups of symmetrical side components 2 are formed on the surface of the aluminum profile base 1, side air ducts 3 and intermediate air ducts 4 are respectively formed in the two groups of side components 2 and the aluminum profile base 1, a main air duct 5 is formed between the ends of the two groups of side components 2, and cooling fins 6 are formed on the surfaces of the side components 2 and the main air duct 5.

[0024] The two groups of side components 2 are arranged at an angle, the edges of the side air duct 3 and the intermediate air duct 4 are both designed in an arc shape, the main air duct 5 is designed in a ring shape, and the two ends of the ring-shaped main air duct 5 are connected to form an air duct, and the side air duct 3, the intermediate air duct 4 and the main air duct 5 all constitute axial air ducts. In the axial air duct, the unidirectional air flow can quickly take away the heat, thereby accelerating the heat dissipation efficiency.

[0025] The heat dissipation fins 6 are symmetrically arranged with the center of the aluminum profile base 1 as the symmetry axis. The symmetrical arrangement enables the heat dissipation fins 6 to dissipate heat evenly, avoiding local overheating and affecting the heat dissipation efficiency. The ends of the heat dissipation fins 6 are designed in an arc shape. The arc-shaped heat dissipation fins 6 can make the heat have an upward dissipation trend during the process of dissipating heat outwards.

[0026] An external fixing groove 7 is formed in the middle of the heat sink fin 6, and the bottom of the external fixing groove 7 is designed to be flat. The external fixing groove 7 provides a placement surface for setting external connection points. Different groups of connection points can be set in the placement surface.

[0027] Two sets of thermal conductive paste fixing sockets 8 are formed at the bottom end of the aluminum profile base 1. Grooves are provided inside the two sets of thermal conductive paste fixing sockets 8. The two sets of grooves cooperate to form a placement space for the thermal conductive paste to be placed. The ends of the grooves are designed to be arc-shaped. The arc-shaped ends of the grooves restrict the ends of the thermal conductive paste after entering and prevent them from falling out.

[0028] A plurality of groups of pressing protrusions 9 are formed at the lower part of the aluminum profile base 1, and each group of pressing protrusions 9 extends downward into the placement space. With the support of the pressing protrusions 9, the thermal conductive strips arranged in the placement space will be squeezed by the pressing protrusions 9, so that when the pressing protrusions 9 come into contact with the electronic components, they will be subjected to continuous and stable downward pressure, thereby ensuring the stability of the fitting state, so that the heat of the electronic components can be stably transferred to the aluminum profile base 1 through the thermal conductive paste.
