Description

Fixed structure of radiator

technical field

The utility model relates to a fixing structure, in particular to a fixing structure of a radiator.

Background technique

When using internal devices in personal computers and notebook computers, such as motherboards, central processing units and integrated circuit components, etc., heat-generating components will generate high heat during operation. The faster the processing speed, the higher the relative heat energy generated. It will result in a reduction in execution speed or even affect the service life of components. At this time, dissipating heat energy in a timely manner is a necessary solution.

In order to improve the above problems, the most common way in the prior art is to directly install a radiator on the heating component to assist the heating component to dissipate heat. The radiator is composed of a heat dissipation pipe, a heat dissipation plate, a heat dissipation fin or a fan. In addition, in order to ensure that the radiator can be installed stably, a fixing frame is usually used to fix the position of the radiator and the heating element, so that the radiator does not slide easily and can maintain a better heat dissipation effect.

However, the assembly holes for assembling the heat sink on the heat-generating components will change due to the shape and size of the heat-generating components. For example, depending on the CPU chip manufacturer, there are at least a distinction between rectangular and square-sized assembly holes. As a result, the size of the CPU chip with the same specification is different, so that the size of the assembly holes of the same specification will also change. So many changes in the assembly holes make it impossible for the manufacturer of the radiator to pre-judge the cooling frame that needs to be used. In turn, many radiator fixing frames of different specifications will be attached to the radiator packaging box sold in the market, so that consumers can choose to assemble the radiator by themselves, but this relatively leads to an increase in the cost of the product.

Therefore, how to solve the above problems becomes the improved goal of the present invention.
