Embodiment Construction

[0037] A liquid cooling system according to a first embodiment of the present invention is described. figure 1 is a perspective view showing a part of the internal structure of a projector in which the liquid cooling system of the present invention is installed. exist figure 1 In , the case is omitted to show the internal structure.

[0038] The projector according to this embodiment includes an imaging unit 1 , three LED (Light Emitting Diode) light source units 2 arranged around the imaging unit 1 , a projection lens 3 for projecting an image formed by the imaging unit 1 , and a liquid cooling system 4 .

[0039] The three LED light source units 2 respectively include a red light source unit 2R that generates red light, a green light source unit 2G that generates green light, and a blue light source unit 2B that generates blue light. Such as figure 2 As shown, each light source unit 2 includes: at least one pair of holders 11 (LED 10 is mounted in each bracket 11); a coo...

Abstract

Disclosed is a liquid-cooling system mounted on an electronic apparatus. The liquid-cooling system has a flow channel (20) wherein a cooling medium is circulated, and a pump (21) and a reserve tank (22) which are disposed on the flow channel (20). A part of the side surface of the reserve tank (22) is set back to the vicinity of the center of the reserve tank (22) and forms a recessed section (40), and at the center on the front surface of the recessed section (40), a flow out port (42) from which the cooling medium flows out is formed.

Description

technical field [0001] The present invention relates to liquid cooling systems mounted on electronic equipment. Background technique [0002] Electronic equipment such as personal computers or projectors include elements or light sources that generate heat during operation. Electronic devices also include components or elements that are heated by heat generated from the element or light source. For example, a CPU (Central Processing Unit) included in a personal computer or a discharge lamp or LED (Light Emitting Diode) included in a projector generates heat during its operation. Also, a memory or a hard disk included in a personal computer is heated by heat generated by the CPU. An imaging element (liquid crystal panel or DMD (Digital Micromirror Device)) included in a projector or a mirror, lens, or polarizing plate arranged on an optical path is heated by heat generated by a light source (heat of light output from the light source). This requires cooling of the element,...
