Description of the Invention: [Technical Field] The present invention relates to a heat dissipation module, and more particularly to a detachable heat dissipation module. [Prior Art] In recent years, the rapid advancement of the computer technology has led to an increase in the speed of operation of the computer, and the heat generation rate of electronic components inside the computer mainframe has continued to rise. In order to prevent the electronic components inside the computer from overheating, which causes temporary or permanent failure of the electronic components, it is very important to provide sufficient heat dissipation performance to the electronic components inside the computer. Taking the central processing unit 7L (CPU) as an example, the towel processing unit under the high-speed operation 'when the temperature of the towel processing unit itself exceeds its working temperature, the towel processing unit Mistakes or temporary failures will cause the computer to crash. In addition, when the temperature of the central processing soap 70 itself is far beyond its normal operating temperature range, it is highly likely that the central processing unit will be damaged, resulting in permanent failure of the central processing unit. ^曰体' In addition, as far as the server is concerned, because of the long distance and the large amount of data processing, the household _ server is equipped with 2 days of guards. • The shell is then determined by another = by / fixed = : 1313800 TW95077GB 22350twf.doc/e Servo, when the fan of the fan body is used for a long time, the damage will be broken due to excessive temperature.

The conventional heat dissipation module has a casing and two fan bodies. Under normal normality, only one of the two fan bodies operates to dissipate heat. When the fan of one of the two fan bodies is damaged due to long-term use, the fan of the other fan body will be able to operate immediately for heat dissipation, so that the server will not crash due to excessive temperature. However, when the repairman replaces the damaged fan body, the repairman must turn off the servo for a period of time to unscrew the fixing screws of the damaged fan body, and then put the new fan body into the screw body and screw it to the housing. Inside. It can be seen from the above that the maintenance step of another conventional heat dissipation module is cumbersome and must be repaired while the server is turned off, thereby causing inconvenience to the user.

Referring to FIG. 2, FIG. 3 and FIG. 4, after the housing (10) is fixed in the main body (not shown) (for example, by turning a plurality of screws), the user can use each of the fan bodies 230 by two The second sliding portions 242 of the connecting portion 24 and the first sliding portions 222 of the first connecting portions 22 are slidably disposed to each other and disposed in the casing 21 〇β. Then, each of the wind bodies 230 is fixed to the casing by the mutual engagement of the second fastening portions 2 of the two second connecting portions 24 and the first fastening portions 224 of the two first connecting portions 220. Within 210. In this embodiment, each of the first sliding portions 222 is a sliding handle, and each of the second sliding portions 242 is a slider. However, as long as the function of the fan body 230 sliding in the housing 21 is not affected, the designer can design each of the first sliding portions 222 as a slider according to the requirements of the setting, and each second sliding The portion 242 is a slide rail, but the above situation is not shown in the drawing. In addition, when the fan modules 230 are disposed and fixed in the housing 21, the second connectors 236 are respectively inserted into the first connectors 218, so that the fan bodies 230 can be connected to the host. The power supply transmitted by the first connector 218 of the 131313800 TW95077GB 22350 twf.doc/e is used to drive the fan 232 to achieve the purpose of dissipating heat from the heat sink module 2 to the host (not shown). . It should be noted that the heat dissipation module 200 generally only operates one fan body 230 to dissipate heat. When the fan body 23 is damaged, the other fan body 230 that is spared can be replaced immediately to continue the heat dissipation function. It should be emphasized that the maintenance personnel can press the two fourth fastening portions 246 disposed on the damaged fan body 230 in the direction of the fan body 230 in the case of a host (not shown). The fourth fastening portions 246 are no longer buckled by the first fastening portions 224 to pull the damaged fan body 230 away from the housing 21 . In other words, the heat dissipation module of this embodiment has a hot-plug function. In summary, the heat dissipation module of the present invention has at least the following advantages: 1. The fan body of the heat dissipation module of the present invention is fixed by the sliding connection and the buckle of the second connection portion and the first connection portion. In the casing, it is easy to assemble or disassemble the fan body of the present invention to the casing as compared with the conventional technique. 2. Since the heat dissipation module of the present invention can have a plurality of fan bodies, when one of the fan bodies is damaged, the other of the fan bodies can be operated in time to dissipate heat, thereby maintaining the normal operation of the host. .
