Cooling apparatus and power converter

Abstract

This invention provides a cooling apparatus which has high strength and good heat dissipation. The cooling apparatus comprises a heat exchanger (1). The heat exchanger (1) is joined to an evaporator (14) disposed below the heat exchanger (1) in a face-to-face manner. The heat exchanger (1) in its receiving part (3) has a heat exchanger high-temperature liquid delivery port (7) and has a two-phasefluid intromission port (6) at its joint to the evaporator (14). The heat exchanger (1) in its outlet header (4) has an intermediate liquid delivery port (8) at its joint to the evaporator (14). The evaporator (14) has, at its joint to the heat exchanger (1), a two-phase fluid delivery port (42) opposed to the two-phase fluid intromission port (6) in the receiving part (3) and has, at its joint to the heat exchanger (1), an intermediate liquid intromission port (41) opposed to the intermediate liquid delivery port (8) in the outlet header (3).

Description

Technical field [0001] The present invention involves the heat transmitter, a cooling device that involves the heat of the cooling hair, and the power transformation device using the cooling device. Background technique [0002] In recent years, a large number of electronic instruments have been used in important equipment for energy supply equipment, information and communication equipment, and transportation equipment.These electronic instruments must be able to move stable and reliable, and need to effectively release the heat of electronic instruments.Although there are various ways to heat up, as one of the high -reliability of heat -saving, environmental protection with high reliability, there are cooling devices (for example, referring to patent literature 1).In this cooling device, it is composed of the density difference in circulating solutions generated by the circulating solution of the circulating solution (buoyancy generated by the density difference) in the circula...

AI Technical Summary

Problems solved by technology

[0005] The conventional cooling device as above has a problem of low strength because the gas-liquid two-phase fluid feeding pipe for feeding and sending out the circulating solution for heat exchange to and from the heating heat exchanger is composed of piping.
