HEAT RADIATOR FOR PORTABLE ELECTRONIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To make excellent the heat radiating performance of heat radiated from a heating electronic part such as a CPU. SOLUTION: This heat radiator is provided with a heat transferring member 8 arranged in a housing 3a of a personal computer main body 3 and closely connected with a CPU 6 and a radiator plate 9 arranged at a display device 4. The radiator plate 9 is formed of a coupled board 10 constituted of two aluminum boards and provided with a hollow bulged part 11 of a required pattern between the both boards. The hollow bulged part 11 is provided with two short straight line parts 11c opened to the peripheral edge of the coupled board 10. The both edge parts of a pipe 12 is connected so as to be communicated with the openings of the short straight line parts 11c. Operating liquid is sealed into the pipe 12 and the hollow bulged part 11 so that a heat pipe part 13 can be obtained. The pipe 12 is provided with a straight tube part 12a positioned on the opening and closing central axial line of the display device 4 to the personal computer main body 3. The straight tube part 12a is inserted into a tubular part 8b formed at the heat transferring member 8 and positioned on the opening and closing central axial line of the display device 4 to the personal computer main body 3 so as to be freely rotatable and so that heat can be transferred.
