An electronic component cooling apparatus includes an air-cooled or water-cooled heat radiating portion and a meandering capillary tube heat pipe which carry out heat transfer between a board having electronic components mounted thereon and the heat radiating portion. The heat radiating portion comprises a plate fin type radiator 21 with an outer-shape of a substantially flat plate. The meandering capillary tube heat pipe is a plate type heat pipe 13 with an outer-shape of a substantially flat plate. The meandering capillary 13c is connected along a surface of the heat radiating portion. Since the meandering capillary tube heat pipe has a very large heat transfer capacity and is able to transfer heat over a long distance with low thermal resistance, it is possible to separate the board apart from the heat radiating portion. Accordingly, flexibility in arrangement of the electronic components or the heat radiating portion is so improved that various shaped apparatus can be designed and manufactured.

1. 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.
