Claim 10:
11. The temperature control system for an etching workbench according to claim 10, wherein the temperature adjustment loop comprises a throttle valve, a compressor and an evaporator pipe section; wherein an input terminal of the compressor is connected to an output terminal of the evaporator pipe section, an output terminal of the compressor is connected to an input terminal of the throttle valve, an output terminal of the throttle valve is connected to an input terminal of the evaporator pipe section, the throttle valve is electrically connected to the controller;
the compressor is configured to drive a temperature control medium in the temperature adjustment loop to flow;
the throttle valve is configured to receive the temperature control instruction from the controller to control a flow of the temperature control medium; and
the temperature control medium flowing through the evaporator pipe section transfers heat with the temperature control fluid in the workbench temperature control fluid loop by the evaporator, so that the target operating temperature of the etching workbench is stabilized within the preset range.
