Description
Technical Field

The fully reinforced computer is deployed in severe environments and needs to have the capability of adapting to various complex severe environments, such as rain protection, salt spray, mould and the like. Along with the development of informatization construction, the requirements on the functions and the performances of the fully-reinforced computer are higher and higher, so that the power consumption of the fully-reinforced computer is greatly increased, the original natural heat dissipation can not meet the heat dissipation requirement of the fully-reinforced computer, and the forced air cooling heat dissipation technology is needed.
The heat dissipation system of the fully reinforced computer is mostly composed of a heat pipe assembly and a fan, and the heat of heat dissipation devices such as a CPU (Central processing Unit), a GPU (graphics processing Unit) and the like is guided to an air outlet through the heat pipe assembly, so that the heat is rapidly dissipated into the air. The fan needs to be arranged outside the machine body, the functional circuit board such as the main board and the like needs to be arranged inside the closed machine body, and therefore the contact part of the heat pipe component and the radiating device is arranged inside the closed machine body, and the contact part of the heat pipe component and the fan is arranged on the machine body, so that the heat pipe component needs to be subjected to sealing design.
In the present day, heat pipe assembly sealing is typically performed at the point of contact with the heat sink. If the heat pipe assembly is externally arranged, an independent cavity is additionally arranged on the back of the machine body and used for placing the heat pipe assembly and the fan, and a layer of cover plate is covered on the outer layer. The method not only leads to the weight increase of the fully-reinforced computer, but also is unfavorable for the light and thin development of equipment; meanwhile, due to multiple assembly, the cover plate cannot be in good contact with the heat pipe assembly, so that the contact thermal resistance of the cover plate and the heat pipe assembly is increased, and the heat dissipation capacity of the fully-reinforced computer is reduced. If the heat pipe assembly is arranged in the air inlet, the heat pipe assembly is sealed by glue filling at the air outlet. The glue filling is usually carried out in a manual glue dispensing mode, but the manual glue dispensing often leads to uncontrollable glue dispensing quantity and poor operation consistency. If the dispensing amount is small, the periphery of the perforation of the heat pipe assembly is not completely sealed, so that the air tightness is invalid; if the dispensing amount is too large, the sealant is accumulated around the perforation of the heat pipe assembly and overflows, and the attractive appearance is poor.
