The utility model relates to a snap-fit radiator module, in particular to a snap-fit radiator module in which a buckle is combined with a radiator in a buckle connection manner

Background technique

The use of electronic information products (such as: computers, etc.) is becoming more and more popular and widely used. Due to the rapid development of electronic information industry technology driven by demand, electronic information is developing towards the trend of increasing computing speed and increasing access capacity. Components in information products generate high heat during high-speed operation.

Taking a computer mainframe as an example, the heat generated by its internal central processing unit (CPU) accounts for the majority. In addition, when the heat accumulation of the central processing unit exceeds its allowable limit, it will cause the computer to crash; and, in order to solve the problem of electromagnetic radiation The problem is that the computer mainframe is usually enclosed by a casing, so that how to quickly extract the heat energy of the central processing unit and other heat dissipation components (or components) has become an important issue.

The way that the central processing unit solves the problem of heat dissipation is to set up a radiator (heatsink) roughly above it, and one side of the radiator is distributed with several fins, and the other side of the radiator (without fins) is in contact with the radiator. The central processing unit conducts the heat energy to the above-mentioned fin ends, and dissipates the heat energy rapidly by radiation or by adding a fan.

In the combination of traditional heat sink and central processing unit, it is necessary to combine the heat sink with the fastener first, and then use the fastener to assist the heat sink to be fixed on the substrate, so that the heat sink can be connected with the central processing unit for heat dissipation. Most commonly, the tool is fixed to the heat sink in a locking manner through screws or other fixing elements.

In addition, heat sinks with a general stack-fin design are manufactured by welding. The bottom plate and fasteners on the heat sink are used to provide spring screws or PUSH-PIN installation positions. This design needs to use solder paste to weld the fins on the base plate, which requires a lot of solder paste consumption, and when the base plate and fins are made of aluminum, it needs to be treated with electroless nickel plating to make the two parts solderable. It can be combined. The main disadvantage of this type of design is that it cannot be used in non-welded designs, because the non-welded bottom plate cannot use spring screws or PUSH-PINs to combine with CPU or GPU for heat dissipation; so the existing technology has the following disadvantages:

1. High cost;

2. The assembly time is longer;

3. The assembly method is limited;

4. Environmental issues.
