Liquid-cooling type thermal module

Abstract

A liquid-cooling type thermal module includes a liquid cooling unit and at least one heat pipe. The heat pipe has a heat-absorbing end and a heat-dissipating end. The heat-absorbing end is connected to at least one heat-producing element. The heat-producing element is located inside a system while the liquid cooling unit is located outside the system. The heat pipe connects the heat-producing element to the liquid cooling unit. Heat produced by the heat-producing element is absorbed by the heat-absorbing end and transferred to the remote liquid cooling unit via the heat-dissipating end to be dissipated. With the heat pipe being used as a medium for conducting heat, the problem of fluid leak can be eliminated, and the heat produced by the heat-producing element can be effectively carried away from the system without stagnating around the heat-producing element, enabling the thermal module to provide excellent heat dissipating effect.
