Abstract

The invention discloses an over-temperature regulating device and method suitable for a heating tube of a Stirling engine, comprising a pipeline and a heat collecting cavity, the pipeline is arranged on the inner wall of the heat collecting cavity, and the pipeline communicates with a cooling water source. When the temperature of the pipe wall of the heating pipe exceeds the preset threshold, the controller controls to open the solenoid valve used to control the on-off of the water in the pipe, so that the water inside the pipe flows, the temperature of the inner wall of the heat collecting chamber drops rapidly, and the temperature of the inner wall of the heat collecting chamber The decrease of the heat collection chamber will increase the radiation heat transfer between the inner wall of the heat collecting chamber and the heating tube, thereby reducing the temperature of the heating tube. It can be seen that when the temperature of the heating tube wall exceeds the temperature, it is not necessary to cut off the light spot and suspend the operation of the power generation device. It makes the operation more stable, does not interrupt the power generation, and ensures stable power output.

Description

technical field

[0001] The invention belongs to the technical field of Stirling engines, and in particular relates to an over-temperature regulating device and method suitable for heating tubes of Stirling engines. Background technique

[0002] When the dish-type Stirling power generation device is operating in the field, when the light intensity exceeds the design value, the pressure may have reached the upper limit at this time, which may cause the heating pipe or heat-absorbing parts to overheat. The measures taken can only ensure the safety and reliability of the power generation device by removing the light spot. However, the removal of the light spot will not only reduce the power generation of the power generation device instantaneously, causing fluctuations to the power grid, but also make the solar energy during the time of cutting the light spot unusable, resulting in a decrease in efficiency.
