Description

A multi-medium composite camera module heat dissipation structure for nuclear power plants

Technical Field

The utility model relates to the technical field of a heat dissipation structure, in particular to a heat dissipation structure for a nuclear power plant used to reduce the local overheating problem caused by the heat generated when a camera module in a closed and narrow space is running.

Background Art

As a high-density unit integrating optics, mechanics, electricity and computing, the camera module will generate a lot of heat during its operation, especially the computing processing chip in the module. Due to its small size and high power, part of the power loss will be released as heat during use. The heat will not only have an adverse effect on the equipment, but in severe cases it may even damage the computing processing chip, greatly shortening its service life.

Traditional heat dissipation methods include heat sinks, air cooling, water cooling, etc. However, the heat sink has low thermal conductivity, while air cooling and water cooling have high thermal conductivity but require a larger volume. Therefore, traditional heat dissipation methods cannot meet the heat dissipation needs of camera modules in closed and narrow spaces.

The technical solution of the utility model is as follows: a multi-medium composite camera module heat dissipation structure for a nuclear power plant, the heat dissipation structure comprising: a camera module, a fixing device and a heat-conducting structure body;

The heat-conducting structure body is an integral frame, including: a solid heat-conducting gasket, a heat-conducting plate, a heat-conducting connecting plate, an outer heat-conducting plate and a liquid heat sink;

The fixing device has a through hole in the middle and is installed on the outside of the camera module; the top has a groove for installing the camera module so that the camera module is in contact with the side of the heat conducting plate;

The solid thermally conductive pad is installed between the camera module and the fixing device to provide insulation protection for the electronic components of the camera module and make heat conduction faster;

A heat-conducting connecting plate is installed on the top of the heat-conducting plate;

An outer heat-conducting plate is installed on the top of the heat-conducting connecting plate; and

A groove is provided on the top of the outer heat conducting plate, and a layer of liquid heat dissipant is attached in the groove, which can disperse the heat conducted from the camera module, the heat conducting plate, the heat conducting connecting plate and the outer heat conducting plate to the outside air.

Furthermore, the heat conducting plate, the heat conducting connecting plate and the outer heat conducting plate are made of copper plate.

Furthermore, the thermally conductive gasket is made of solid thermally conductive silicone.

Furthermore, the heat-conducting connecting plate is provided with a plurality of hollow circular holes, and rivets for fixing are installed on both sides.

Solid thermally conductive silicone fills the gap between the camera module and the thermal conductive plate, making the contact between the camera module and the thermal conductive plate closer, reducing the adverse effect of air in the gap on heat conduction, making heat conduction smoother and faster, thereby achieving a rapid reduction in the temperature of the camera module. At the same time, it can provide a certain degree of insulation protection for the camera module, effectively improving the safety of the equipment during use.

2. The use of heat-conducting plates, heat-conducting connecting plates and outer heat-conducting plates increases the heat dissipation area and effectively improves the heat dissipation efficiency.

3. Liquid thermal grease efficiently distributes the heat conducted from the camera module through the thermal pad, thermal plate, thermal connection plate and outer thermal plate to the outside air, while making the overall structure seamlessly connected when used with other devices.

4. The hollow circular hole design of the thermal conductive connecting plate effectively reduces the total weight of the heat dissipation structure.
