Abstract:
A cooling apparatus for cooling a plurality of boards having electronic components mounted thereon, the boards being arranged in a row, wherein the apparatus comprises:a plate fin type air-cooled or liquid-cooled radiator; and a plate type meandering capillary tube heat pipe that transfers heat between end faces of the boards and the radiator; wherein the plate type meandering capillary tube heat pipe comprises a first part that is a sidewall of the electronic component cooling apparatus, and a second part that is bent at an end of the sidewall and that is connected along the radiator; and wherein: (i) the plate type meandering capillary tube heat pipe comprises a capillary that is sealed off from the outside; (ii) one part of the capillary acts as a heat radiating portion and another part of the capillary acts as a heat receiving portion; (iii) the heat receiving portion and the heat radiating portion are alternately arranged, and the capillary meanders between the heat receiving portion and the heat radiating portion; (iv) a two-phase condensable working fluid is sealed inside the capillary; and (v) the capillary has a diameter less than a maximum diameter which allows the two-phase condensable working fluid to circulate and move while being sealed inside the capillary.
