Description

Water cooling head fastener structure

Technical Field

The utility model relates to a fastener structure, especially a water-cooling head fastener structure.

Background

With the rapid development of the electronic industry, the operation speed of the information semiconductor industry chip is continuously increased, and the integration level is also increased, so that a large amount of heat is generated during the operation of the chip and the temperature of the system is increased, thereby affecting the stability of the system. To ensure the system operates properly, a water cooling head is usually mounted on the wafer to dissipate the heat generated by the wafer, and a conventional water cooling head 901 is fixed at the corner by screws 902, so that the heat exchange surface of the water cooling head can be tightly attached to a heat source 909 (as shown in fig. 1A).

However, the downward pressure generated by the four-corner locking method is the strongest at the screw 902 and the second is the edge formed by connecting the two screws 902, so the downward pressure at the center of the water head 901 is the weakest, which tends to generate a gap G between the water head and the heat source 909, and the heat cannot be effectively transferred to the heat exchange surface of the water head 901 (as shown in fig. 1B).

In addition, there is also a fixing structure of a water cooling head at present, wherein screws 903 are arranged on two sides of the water cooling head 901, a pressure rod 904 is arranged on the water cooling head in a spanning manner, and the down pressure intensity of the spring 906 is changed by changing the position of a nut 905, so that the water cooling head can be tightly attached to a heat source (as shown in fig. 1C).

Similarly, although the pressing rod 904 crosses the center of the water cooling head 901, the actual part of the downward pressure is still at the screw 903, the nut 905 and the spring 906, and the downward pressure at the center of the pressing rod 904 is the weakest, which causes the pressing rod 904 to deform, so that the downward pressure at the center of the water cooling head cannot be obtained, and a gap is generated between the water cooling head and the heat source, so that the heat cannot be effectively transmitted to the heat exchange surface of the water cooling head 901 (as shown in fig. 1D).

In addition, in the above structure, when the water cooling head and the heat source are pressed more tightly, each screw (or nut) needs to be screwed in sequence, such adjustment is quite troublesome, and it is impossible to ensure that the pressing force of each screw is the same, which easily causes the problems of uneven contact, generation of gaps between the heat exchange surface and the heat source, and the like, and the problems of poor heat dissipation efficiency due to poor heat conduction, and the like.
