It is different from the prior art, present invention discloses a kind of traction locomotive pumps to drive evaporation-cooled device, specific work
It is as follows to make principle:
On the one hand, the outlet of the import connection fluid reservoir 1 of working medium pump 2, is responsible for extracting the liquid refrigerant in fluid reservoir 1, its is defeated
It send to microchannel cold plates 6, since microchannel cold plates 6 are close to the heating module in traction locomotive, so that heating module
Heat the working medium in microchannel cold plates 6 is evaporated so that working medium becomes gaseous state from liquid, temperature is remained unchanged, absorb
The heat of heating module；The outlet of microchannel cold plates 6 is connected with the import of condenser 7, and gaseous working medium enters in condenser 7,
So that the gaseous working medium of high temperature, which liquefies, becomes the liquid refrigerant of low temperature again, heat release is carried out, then pass through the condensation fan in condenser 7
Heat is distributed into atmosphere, and the liquid refrigerant formed that liquefies is stored in circulating reflux fluid reservoir 1 again.
On the other hand, temperature transmitter 4, pressure transmitter 5 are installed at the import and export of microchannel cold plates 6, pass through temperature
Transmitter 4 and pressure transmitter 5 monitor the temperature and pressures of the inlet and outlet of microchannel cold plates 6, then when PLC control system is logical
When excess temperature transmitter 4 detects that 6 outlet temperature of microchannel cold plates is excessively high, then the revolving speed of working medium pump 2 is improved, to increase liquid
The internal circulating load of working medium, to guarantee refrigerating capacity；When PLC control system detects that microchannel cold plates 6 export by temperature transmitter 4
