Abstract

The invention belongs to the field of heat dissipation equipment, and specifically discloses a heat dissipation apparatus. The heat dissipation apparatus comprises a heat dissipation panel and a heat dissipation pipe, wherein a groove body is formed in the heat dissipation panel; the heat dissipation pipe is mounted on the heat dissipation panel through the groove body; at least one part of the outer wall of the heat dissipation pipe is provided with concave parts which surround the periphery of the heat dissipation pipe; and the concave parts and the inner wall of the groove body are connected through a wedding filling material. Compared with the prior art, the concave parts are annularly arranged on the surface of the heat dissipation pipe; the welding filling material is arranged between the concave parts and the inner wall of the groove body; and the welding filling material can smoothly enter the gap between the concave parts and the inner wall of the groove body through the concave parts to fill the gap so as to enable the concave parts and the inner wall of the groove body to be tightly connected, so that the contact area between the heat dissipation pipe and the heat dissipation panel is enlarged, the heat resistance is lowered consequently, the thermal conductivity of the heat dissipation pipe and the heat dissipation panel is improved, and the heat dissipation effect of the heat dissipation apparatus is improved. The invention also provides a manufacturing method for the heat dissipation apparatus; and the manufacturing method is simple in process and easy to operate.

Description

technical field [0001] The invention belongs to the field of heat dissipation equipment, in particular to a heat dissipation device and a manufacturing method thereof.

Heat sinks are generally divided into three types: air-cooled heat dissipation, metal heat conduction, and water-cooled heat dissipation. [0003] Among them, although the heat dissipation effect of air-cooled heat dissipation is obvious, because there may be corrosive gas in the working environment of the cooled equipment, the corrosive gas will be brought into the equipment during air-cooled heat dissipation, thereby accelerating the corrosion of its internal circuit and shortening its temperature.

Problems solved by technology

[0003] Among them, although the heat dissipation effect of air-cooled heat dissipation is obvious, because there may be corrosive gas in the working environment of the cooled equipment, the corrosive gas will be brought into the equipment during air-cooled heat dissipation, thereby accelerating the corrosion of its internal circuit and shortening its temperature. Lifespan: Although the heat dissipation effect of metal heat conduction is good, when the heat output of the equipment to be cooled is large, more metal heat conduction sheets are required, which takes up a large space and increases the weight of the equipment to be cooled. If aluminum heat conduction sheets are used, the weight is Reduced, but because the aluminum heat conduction sheet is easily corroded by alkaline substances, it needs anti-corrosion treatment, which increases the cost; the heat dissipation effect of water-cooled heat dissipation is good, and the heat dissipation efficiency is high. However, when the existing heat dissipation pipe and heat dissipation plate are matched, they will be affected by factors such as the flatness and roughness of the surface of the heat dissipation pipe. Therefore, there will be a phenomenon that the heat dissipation pipe and the heat dissipation plate are not tightly fitted. When the fit of the part is not tight, it will seriously affect the heat dissipation of the heating element and affect the heat dissipation effect
