[0017] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0018] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0019] like Figure 1 and Figure 2As shown, a specific embodiment of the utility model provides a high temperature resistant chip module, which has a high temperature resistance function to ensure the stability of operation in a high temperature environment, and specifically includes a chip body 100 and an installed heat dissipation mechanism; the installed heat dissipation mechanism includes a fixed plate 200, and an installation position 210 connected to the chip body 100 signal is provided at the upper end of the fixed plate 200, and a heat sink 300 capable of surface contact with the chip body 100 is provided above the installation position 210, and a fixing column 310 passing through the fixing plate 200 is provided at the edge of the heat sink 300, and a heat dissipation fan 400 is fixed on the side of the heat sink 300 away from the chip body, and spaced heat dissipation fins are provided on the side of the heat sink 300 opposite to the heat dissipation fan 400.

[0020] like Figure 1 and Figure 2 As shown, through the above settings, the fixing plate 200 in this embodiment is used to install the chip body 100. After the chip body 100 is embedded in the mounting position 210, the heat sink 300 is fixed on the outer surface of the chip body 100. The heat generated when the chip is running is conducted out by the heat sink 300. Since the surface of the heat sink 300 has heat dissipation fins, the heat dissipation area can be increased. At the same time, the heat dissipation fan is used to dissipate the heat in the heat dissipation fins and the thermal conductive coating, which can effectively improve the heat dissipation efficiency of the chip body 100. When the chip is running at high temperature, the heat can be dissipated in time to ensure the stability of the chip running at high temperature. In addition, in order to ensure the stability of the chip body 100 installed on the fixing plate 200, the fixing buckles 600 for fixing the chip body 100 are provided on both sides of the mounting position 210 in this embodiment, and the two fixing buckles 600 are arranged symmetrically. When the chip body 100 is inserted into the mounting position 210, the fixing buckles 600 are fixed to prevent the chip body 100 structure from falling off.

[0021] like Figure 1 and Figure 2 As shown, in order to improve the heat dissipation efficiency of the heat sink 300 to the chip body 100, this embodiment is provided with a hollow heat conducting sheet 500 between the heat sink 300 and the chip body 100, and the heat conducting sheet 500 is coated with heat dissipation silicone grease. In this way, the heat generated by the operation of the chip body 100 is quickly discharged from the chip body 100 by the heat dissipation silicone grease on the heat conducting sheet 500, further improving the heat dissipation efficiency.

[0022] As mentioned above, the heat dissipation fan 400 for dissipating the heat of the chip is installed on the outside of the heat dissipation plate 300. In order to install the heat dissipation fan 400 structure, a mounting plate 700 is hinged on the upper end of the fixed plate 200 in this embodiment. The mounting plate 700 is provided with a guide port. The heat dissipation fan 400 is fixed inside the guide port. The mounting plate 700 is provided with a torsion spring at the hinged end of the fixing plate 200. The other end of the mounting plate 700 is provided with a clamping and fixing with the edge of the fixing plate 200. In this way, the mounting plate 700 can install the heat dissipation fan 400 inside the guide port. After the mounting plate 700 is fixed on the fixing plate 200, the torsion spring accumulates elastic force. When the mounting plate 700 is opened, it automatically rotates outward, which is convenient for opening the mounting plate 700 to repair the internal heat dissipation structure. In order to avoid the mounting plate 700 from affecting the heat dissipation plate 300, the mounting plate 700 in this embodiment is hollowed out, and the inner side of the mounting plate 700 is provided with reinforcing ribs arranged outward along the guide port. The hollow layout ensures heat dissipation efficiency.

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, the fixing plate 200 and the heat sink 300 are fixed by plug-in cooperation. In this embodiment, a fixing hole 220 for the fixing column 310 to pass through is provided on the outer side of the fixing plate 200 corresponding to the mounting position 210, and a fixing screw screwed with the fixing hole 220 is provided in the fixing hole 220. In this way, when the fixing column 310 of the heat sink 300 is inserted into the fixing hole 220, the heat sink 300 is fixed by the fixing screw; after the chip is assembled on the control board, it needs to be connected with the circuit for control. In this embodiment, a connection terminal 800 electrically connected to the mounting position 210 is provided on the outer side of the fixing plate 200. The connection terminal 800 can be installed by welding.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
