Description

Technical Field

[0001] The utility model relates to the technical field of heat sinks, in particular to a new type of power box heat sink. Background Art

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in an electrical appliance. It is mostly made of aluminum alloy, brass or bronze. For example, a large heat sink is required for the CPU (Central Processing Unit) in a computer, and heat sinks are also required for the power tubes, line output tubes in a TV set, and power amplifier tubes in a power amplifier. Generally, a layer of thermal grease needs to be applied on the contact surface between the electronic component and the heat sink during use, so that the heat generated by the component can be more effectively conducted to the heat sink and then dissipated into the surrounding air through the heat sink.

[0003] Currently, most of the heat dissipation plates used for power box heat dissipation on the market are usually an integrated structure composed of multiple flat plates. Most users can only replace the heat sink as a whole, which increases the user's usage cost. During installation, after long-term operation, the heat sink will be covered with dust, resulting in a reduction in heat dissipation effect. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problem that the heat dissipation effect of the existing heat sink is reduced after long-term operation, and provide

[0005] A new type of power box heat sink, including

[0006] A connecting plate, on which a plurality of unit heat dissipation plates are uniformly arranged; V-shaped grooves are uniformly formed on the surface of the unit heat dissipation plates;

[0007] A contact space is arranged at one corner of the unit heat dissipation plate for contacting with the radiator main body;

[0008] Insertion protrusions are integrally arranged at the bottom of the unit heat dissipation plate and the lower edge of the contact space, and a contact strip is integrally arranged at the side edge of the contact space.

[0009] Further, an installation notch is formed in the middle of the unit heat dissipation plate, and the installation notch is located in the middle of the side edge of the contact space.

[0010] Further, the connecting plate is arranged in a long strip shape, and a slot is formed in the connecting plate along the length direction; the installation notch is connected to the slot.

[0011] Further, after the connecting plate is inserted, the height of the end part is the same as the height of the side wall edge of the contact space.

[0012] The beneficial effects of the present utility model are as follows: By providing V-shaped grooves on the surface of the flat plate body, the contact area between the plate surface and the outside world is increased, improving the heat dissipation performance. At the same time, combined with a detachable connection method, the unit heat sink contaminated with dust can be replaced and cleaned in a timely manner to ensure the heat conduction effect.

[0019] Embodiment 1

[0020] As Figures 1 to 3 shown, a new type of power box heat sink includes a connecting plate 2. The connecting plate 2 is arranged in a long strip shape, and a slot 21 is provided along the length direction of the connecting plate 2. In this solution, the slot 21 is used to insert the unit heat dissipation plate 1. During use, according to the heat dissipation requirements, different numbers of unit heat dissipation plates 1 and the distances between the unit heat dissipation plates 1 can be set. An installation notch 10 is provided in the middle of the unit heat dissipation plate 1, and the installation notch 10 is located in the middle of the side edge of the contact space 100. The installation notch 10 is connected to the slot 21. After the connecting plate 2 is inserted, the height of the end part is the same as the height of the side wall edge of the contact space 100.

[0021] A plurality of unit heat dissipation plates 1 are uniformly arranged on the connecting plate 2; V-shaped grooves 13 are uniformly formed on the surface of the unit heat dissipation plate 1; by providing the V-shaped grooves 13, the surface area of the unit heat dissipation plate 1 is increased, and the heat dissipation performance of the unit heat dissipation plate 1 can be effectively improved.

[0022] In order to enable this heat sink to stably contact the heating element, a contact space 100 is provided at one corner of the unit heat dissipation plate 1 for contacting the radiator main body; specifically, the contact space 100 is set to be rectangular, and when in use, it can be buckled on two adjacent sides of the heating element.

[0023] Insertion protrusions 12 are integrally provided at the bottom of the unit heat dissipation plate 1 and the lower edge of the contact space 100. In this solution, the insertion protrusions 12 are used to integrally mount the heat sink on the outer surface of the heating element. Specifically, a groove corresponding to it is provided on the outer surface of the heating element. Contact strips 11 are integrally provided at the side edges of the contact space 100, and the contact strips 11 are used to increase the contact area between the unit heat sink 1 and the outer surface of the heating element and improve the heat transfer efficiency.

[0024] By providing V-shaped grooves on the flat plate surface, the contact area between the plate surface and the outside is increased, and the heat dissipation performance is improved. At the same time, combined with the detachable connection method, the unit heat sink contaminated with dust can be replaced and cleaned in time to ensure the heat conduction effect.

[0025] The above embodiments only represent the specific implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
