[0002] The ultra-thin uniform temperature plate (hereinafter referred to as uniform temperature plate) is also called ultra-thin VC plate, which is commonly used for heat dissipation of electronic devices such as mobile phones or notebook computers. The existing uniform temperature plate needs to inject water into the uniform temperature plate by using a injection needle during manufacturing, and the water evaporation and the movement of water vapor from the hot end to the cold end are used to realize the heat dissipation. However, due to the small internal space of the ultra-thin uniform temperature plate, the internal capillary water absorption is slow, and the liquid stays in the water injection pipe orifice during liquid injection, which is easy to cause liquid overflow, resulting in inaccurate internal storage amount of the uniform temperature plate product, and leading to product failure. The existing patent CN111220013A provides an ultra-thin uniform temperature plate and a manufacturing process thereof. The invention provides an ultra-thin uniform temperature plate suitable for large and thin, which can ensure to increase 30-50% of the saturated steam flow space when the total thickness of the product is less than 0.4mm, and the overall heat dissipation performance will be improved by more than 30%.
