Liquid cooling heat dissipation device and liquid cooling heat dissipation temperature control method

Abstract

A liquid-cooling heat dissipation device is used for implementing a liquid-cooling heat dissipation temperature control method to pump a cooling liquid to cool a heat source. The liquid-cooled heat dissipation temperature control method includes contacting a heat source with a liquid cooling head to absorb the heat generated by the heat source, and allowing the cooling liquid to pass through for heat exchange; connecting a heat sink to the liquid cooling head to form a cooling liquid circulation Flowing circulation pipeline; detect the temperature of the heat source, the inlet liquid temperature of the heat sink, and the liquid outlet temperature of the heat sink; judge whether the temperature of the heat source is greater than a high temperature warning value, and calculate the temperature between the liquid outlet temperature and the liquid inlet temperature Difference. When the temperature of the heat source is not greater than the high temperature warning value, the method adjusts the forced cooling efficiency of the radiator or the flow rate of the pumped cooling liquid according to the temperature difference, so as to meet the temperature control requirements and noise control.

Description

technical field [0001] The invention relates to liquid cooling technology, in particular to a liquid cooling device and a liquid cooling control method applied to computer devices. Background technique [0002] A water-cooling heat dissipation device for a computer mainframe usually includes a radiator connected to a pump and a water-cooling head, and a fan is used to strongly cool the radiator. Under the aforementioned structure, the main noise of the water-cooled heat sink comes from the operation of the pump, the flow of the coolant, and the rotation of the fan. [0003] The water cooling device is usually set to operate in two modes: low power mode and high power mode. The above two modes only detect the temperature of the heat source (such as CPU, graphics chip). When the temperature exceeds the warning value, the fan and the pump will run at full speed at the same time; when the temperature is lower than the warning value, the fan and the pump will reduce the operatio...

AI Technical Summary

Problems solved by technology

The above two modes only detect the temperature of the heat source (such as CPU, graphics chip). When the temperature exceeds the warning value, the fan and the pump will run at full speed at the same time; when the temperature is lower than the warning value, the fan and the pump will reduce the operation power

[0004] However, in common water cooling devices, the user cannot adjust the operating power of the fan and the pump, only in two low-power modes and high-power modes

In the low power mode, although the fan and the pump reduce the operating power, individual users have different feelings about the noise level of the fan and the pump, and the computer case itself may amplify the noise of either the fan or the pump due to resonance

[0005] However, if the user is directly involved in the fan or pump speed switching, the heat dissipation efficiency may be poor or the coolant flow may be insufficient, and the operating state may be quickly switched to a high power mode.
