Thermal module combination structure

The invention relates to a heat dissipating module assembly structure, in particular to a heat dissipating module assembly structure capable of greatly reducing man-hours and increasing assembly convenience.

In recent years, with the rapid advancement of computer technology, the operation speed of computers has been continuously improved, and the heating power of electronic components inside computer mainframes has continuously increased. In order to prevent the electronic components inside the host computer from overheating, the electronic components are temporarily or permanently disabled, so it is very important to provide sufficient heat dissipation performance to the electronic components inside the computer.

Taking a central processing unit (CPU) as an example, the central processing unit is operating. When the temperature of the central processing unit exceeds its normal operating temperature range, the central processing unit is highly likely to have an operational error, or temporarily Failure, this will cause the computer host to crash. In addition, when the temperature of the central processing unit is far beyond its normal operating temperature range, it is even more likely to damage the internal transistor of the central processing unit chip, thus causing the central processing unit to permanently fail, and thus must be replaced. The central processor can restore the normal operation of the computer.

The conventional heat dissipation module structure mainly comprises a heat sink and a heat dissipation fan, and the heat sink has two heat contact surfaces, and the first heat contact surface is a heat conduction surface between the heat generating electronic component and the bottom of the heat sink, and the second The heat contact surface is a heat convection surface between the heat sink fin of the heat sink and the heat dissipation fan; wherein, in order to maximize the heat conduction, the heat conduction surface between the bottom of the heat sink and the heat generating electronic component must be in a close fitting state; otherwise Regardless of the high efficiency of the heat dissipation module, once there is a gap between the heat conduction surface between the bottom of the heat sink and the heat-generating electronic components, the heat dissipation performance is greatly reduced.

The function of the buckle is to fix the heat-dissipating module firmly on the heat-generating electronic component on the one hand, and to make the heat-transfer maximum performance between the bottom of the heat sink and the heat-generating electronic component on the other hand; Conventional fasteners are not only complex in structure, but all parts and components must be assembled separately. The time and personnel costs involved are very high. In addition, the assembly is complicated, and the user or installer must assemble it. First, the heat dissipating unit (the device) is placed on the heat-generating electronic component, and then the fastener or other components having the holding function are respectively fastened to the heat-dissipating unit, and the heat-dissipating unit is combined with the heat-generating component to be disassembled. At the same time, the operation is reversed in one direction, thus causing substantial inconvenience and trouble in use and assembly.

As mentioned above, the conventional disadvantages have the following disadvantages:

1. Disassembly and assembly is complicated and very inconvenient;
2. Significantly increase assembly hours.

Therefore, how to solve the above problems and problems in the past, that is, the inventors of this case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in order to effectively solve the above problems, the main object of the present invention is to provide a heat dissipating module assembly structure which can greatly reduce the assembly man-hour.

A secondary object of the present invention is to provide a heat dissipation module assembly structure that can greatly increase assembly convenience.

In order to achieve the above object, the present invention provides a heat dissipating device, comprising a heat sink, at least one elastic piece, at least one clamping member and a shaft, the heat sink having a base and a plurality of heat dissipating fins disposed on the base The opposite sides of the base are respectively formed with at least one through hole, and the heat sink is correspondingly disposed on the elastic piece, and the elastic piece is provided with at least one snap post corresponding to the through hole, and the buckle column is slidably Embedded in the clamping member, the clamping member has a first end and a second end. The second end defines a slot, and a cavity is formed in the slot, and a protrusion is formed on the slot. The clamping member is embedded in the accommodating space, the shaft is inserted through the heat sink, and the two ends of the shaft are respectively connected to the buckle column .

Through the design of the foregoing structure, the heat dissipation module further has a substrate, and a heat source is disposed at a center thereof, the heat sink is correspondingly disposed on the elastic piece, and the bottom of the heat sink is in contact with the heat source, when an external force is used for the clip When the first end of the holding member is pulled downward, since the clamping member is slidably embedded on the buckle post, the convex portion passing through the clamping member contacts the buckle post and rotates the clip. After the holding member, the buckle post is pulled up by the convex portion of the clamping member, and at the same time, the elastic piece is pulled up, so that the elastic piece generates an upward action on the heat sink. The force is in contact with the heat sink, so that through the mutual sliding fit of the clamping member and the buckle post, it is necessary to improve the conventional parts to be fixed on the heat dissipation module through complicated parts and The time and cost of the steps, the advantage of the present invention is that the combination of the heat dissipation module can be performed by hand and the utility of the heat dissipation module can be greatly reduced, thereby greatly reducing the man-hour and increasing the assembly convenience.
