Abstract: An integrated liquid cooling device comprises a housing, a first liquid reservoir, a second liquid reservoir, at least one first liquid channel for heat dissipation, a second liquid channel appressed to a heat source device, at least one third liquid channel for heat dissipation and a liquid transfer cycle driver; the first liquid reservoir is connected to the second liquid channel through the first liquid channel; the second liquid channel is connected to the second liquid reservoir through the third liquid channel; the first liquid reservoir and the second liquid reservoir are independent to each other and connected through the liquid transfer cycle driver; the liquid transfer cycle driver transfers the liquid in the second liquid reservoir to the first liquid reservoir. The invention saves the space and reducing the risk of leakage.

Abstract: A cooling system of a light emitting diode (LED) lamp includes: a circulatory pipe, a pump, an LED cooling module and a power source cooling module, wherein the LED cooling module is a fluid cooling mechanism for an LED lamp, the power source cooling module is a fluid cooling mechanism for an LED lamp power source module, the circulatory pipe is connected to the LED cooling module and the power source cooling module, the pump is assembled to the circulatory pipe, causing a fluid in the circulatory pipe to flow through the LED cooling module and the power source cooling module and form a circulatory flow, thereby achieving a cooling and temperature reducing function of the LED lamp and the power source module at the same time.
