Abstract

PURPOSE:To promote radiation of heat from a heat generating member and to unnecessitate constituent parts of a heat exchanger like a motor, by installing a heat exchanging body which is constituted by heat pipes and heat radiating fins coupled together in a unitary manner, such that its heat pipe section is kept in direct contact with the outer surface of the heat generating member. CONSTITUTION:A heat exchanging body 7, which is constituted by heat pipes 8 and heat radiating fins 10 coupled together in a unitary manner, is installed such that its heat pipe section is kept in direct contact with the outer surface of a heat generating member 1. Here, since the lower end portion 13 of each fin 10 is held in contact with the outer surface of the heat generating member 1, heat is transmitted directly to the lower end portions 13 of the fins 10, but heat thus transmitted to the fins 10 is divided by elongated holes 16 and radiated from lower fin sections 18. On the other hand, upper fin sections 17 radiate heat transmitted from upper portions of the heat pipes 8. Thus, the heat of the heat generating member is radiated from two sections of the fins 10 separately. By employing such an arrangement, it is enabled to omit constituent parts of a heat exchanger like a motor and a fan and to save materials and labors required for assembling the apparatus. Further, since heat is radiated not only from the heat pipes but also from the heat generating member directly, radiation of heat by cooling of the heat radiating section can be promoted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchange device that is attached to a heating element that requires cooling heat radiation or partial heat radiation of a power supply rectifier circuit using silicon transistors. As an example of the prior art, Figure 1 shows the cylinder head section of a small refrigerator.
The actual state of cooling heat dissipation is shown. 1 is a cylinder head of a small refrigerator compressor, 2 is a motor 3, a propeller shaft, 7
Number 4 is a fan guard that surrounds the part that cools the cylinder. Reference numeral 5 indicates a motor wiring protection tube, and reference numeral 6 indicates a mounting stay, which is fixed to other equipment so that the heat exchange fan device is located above the cylinder head section 1.

The outer surface of the cylinder head portion 1 becomes hot due to the operation of the compressor. When the propeller fan 4 is rotated to blow air into the high temperature part of the cylinder, heat is radiated from the surface of the cylinder head part 10, and the cylinder head part 1 is cooled. This cylinder head part 1
The entire compressor is moved step by step due to the heat released from the compressor, and the lubricating oil inside the compressor is also cooled, and the viscosity of the lubricating oil is maintained at a level of 3-3 degrees, allowing normal operation of the compressor. ' □However, the conventional type had the disadvantages of having a large number of parts, requiring a lot of management and assembly time, and high cost of materials such as the motor and 7-piece assembly.

The present invention was developed in consideration of the problem of disembarkation, and aims to provide an energy-saving heat exchange device that does not use a motor and reduces materials, processing, and management costs.

In order to achieve the above object, the present invention promotes heat dissipation from the heat generating element by attaching the heat pipe part of the heat exchanger body, which is integrally formed with a heat pipe and heat dissipating fins, to the outer surface of the heat generating element in direct contact with the outer surface of the heat generating element. It has features configured to allow

Hereinafter, the present invention will be explained in detail with reference to an embodiment shown in FIGS. 2 and 3. 7 is a heat exchange device, which includes a plurality of heat pipes 8 connected by U-shaped connecting pipes 9, a large number of aluminum plate fins 10 through which the heat pipes 8 are fixed, and left and right side plates)11. It consists of 12. 13 is the lower end of the aluminum plate fin 10 L
It is bent to the cylinder head part 1 by the mounting plate 14 and plate 15 fixed to the left and right side plates tt and tz so as to contact the outer surface of the cylinder head s1. . Reference numeral 16 is long and large, and is generally cut at an intermediate position between the L-shaped portion of the lower end portion 13 of the aluminum plate fin 10 and the second stage heat pipe group 8a.

A plurality of elongated parts are provided so as to be separated into the upper fin part 17 and the lower fin part 18. Reference numeral 19 denotes a concave protrusion integrally formed on the upper surface of the cylinder head portion 1, into which the heat pipe 8 is inserted. The heat pipe 8 is seated so as to be in contact with the inner wall surface of the recess, and is curved so that heat transfer from the cylinder head 1 is carried out smoothly.

In the heat pipe 8 that is in contact with the heating element Km, the heat medium absorbs heat and evaporates, and in the process of rising toward the heat pipe 8 above, the aluminum plate fin IOK is exposed to the atmosphere. radiates heat. The heat transfer medium that radiated heat gradually condenses and liquefies, flows down another porous passage formed on the inner wall of the heat pipe, returns to the heat pipe 8 part that is in contact with the heating element, and absorbs heat again. and repeat evaporation. Since the lower end 13 of the aluminum plate fin 10 is in contact with the outer surface of the cylinder head 1 of the heating element, there is direct heat transfer, and the heat is separated by the elongated length 16 and transferred to the five lower plate fins 18. Heat is radiated from the On the other hand, the aluminum plate fin/17 in the upper part is divided and has nine functions of dissipating heat by heat transfer from the heat nozzle 8 in the upper part.Since the present invention has the above structure, the motor, 717, etc. No parts are required, reducing materials and assembly man-hours. In addition, for the cooling heat dissipation section, not only heat dissipation by the heat pipe but also direct heat dissipation from the heating element is possible, which promotes cooling heat dissipation.
