Heat Dissipation Apparatus, Heat Dissipation Control Method, and Controller

摘要

A heat dissipation controller is connected to a sensor and a water pump such that the controller correspondingly adjusts the water pump according to the current pressure difference and a preset pressure difference, to control a flow capacity of coolant flowing into a branch water pipe, until an absolute value of a difference between the current pressure difference and the preset pressure difference is less than or equal to a preset error amount. The controller can adjust the flow capacity of the coolant flowing into the branch water pipe to effectively ensure that flow capacities of coolant in all branch water pipes are distributed evenly, and to effectively improve stability of the heat dissipation apparatus.

1. A heat dissipation apparatus, comprising:
a main water pipe; a branch water pipe; a water pump; a sensor; and a controller, wherein the branch water pipe is connected to the main water pipe, wherein the branch water pipe is configured to cool a board mounted on the branch water pipe, wherein the water pump is disposed on the main water pipe, wherein the sensor is disposed on the main water pipe or the branch water pipe, wherein the sensor is configured to obtain inflow pressure of coolant flowing into the branch water pipe and outflow pressure of coolant flowing out of the branch water pipe, wherein the controller is connected to the sensor such that the controller determines a current pressure difference between the inflow pressure and the outflow pressure, wherein the controller is further connected to the water pump such that the controller correspondingly adjusts the water pump according to the current pressure difference and a preset pressure difference, to control a flow capacity of the coolant flowing into the branch water pipe, until an absolute value of a difference between the current pressure difference and the preset pressure difference is less than or equal to a preset error amount, wherein an initial pressure difference is a pressure difference required for ensuring that each component on the board runs without derating, and wherein the preset pressure difference is a maximum value of the initial pressure differences of every two boards of the multiple boards.
