Problems solved by technology

However, in the water cooling method, a circulation system and a pump for circulating the water, and a radiator and a fan for dissipating heat to the outside air are required, which complicates the structure and increases the size of the device.
The cost and power consumption of the device increase, which is unfavorable to the economy
[0009] The cooling method using a Peltier element requires a Peltier element, a heat sink, and a fan, and the power consumption of the Peltier element is also large, so it is not economical

Embodiment 1

[0087] for figure 1 For the heat sink in the shape shown, an aluminum heat sink body (in the figure 1 Among them, a=100mm, b=100mm, c=40mm, d=30mm, e=2mm, f=5mm) by electroplating heat sink coated with Zn, Cr, Ni, Cu, coated with methyl methacrylate - ethyl acrylate The heat sink obtained after ester-styrene copolymer, and the same heat sink made of aluminum without any treatment (hereinafter referred to as fin). Table 1 shows the film thickness of each coating layer.

[0088] Such as Figure 4 As shown, it is formed as an aluminum plate for temperature measurement with a plate made of phenolic plastic (referred to as symbol 4 in the figure, the same below), a heater 5, a thickness of 10 mm, a length of 50 mm, and a width of 50 mm, and a hole 7 for temperature measurement is opened in the transverse direction. 6. As for the configuration of the heat sink 1, the heat sink 1 and the plate 4 made of phenolic plastic are fastened with bolts so that they are in close contact wit...

Embodiment 2

[0094] Same as in Example 1, prepare a heat sink body coated with Zn, Cr, Ni, and Cu by electroplating on an aluminum heat sink body made of aluminum with a height of 100 mm and a width of 100 mm, a fin height of 30 mm, a fin thickness of 2 mm and a height of 5 mm, and a weight of 480 g. sheet, a heat sink obtained after coating methyl methacrylate-ethyl acrylate-styrene copolymer, and the same heat sink made of aluminum without any treatment. Table 2 shows the film thickness of each coating layer.

[0095] Such as Figure 5 As shown, it is formed to successively overlap a plate 4 made of phenolic plastic, a heater 5, an aluminum plate 6 for temperature measurement with a thickness of 10 mm, a length of 50 mm, and a width of 50 mm, and a hole 7 for temperature measurement along the transverse direction, and a heat sink 1. The heat sink 1 and the plate 4 made of phenolic plastic were fastened with bolts so as to be in close contact with each other, and this was used as a test ...

Embodiment 3

[0101] In the same manner as in Example 2, the heat sink body made of aluminum was coated with Zn, Cr, Ni, Cu, and MM, and the same heat sink made of aluminum without any treatment was prepared. Table 3 shows the film thickness of each coating layer.

[0102] A test device in which the plate 4 made of phenolic plastic, the heater 5 , the aluminum plate 6 for temperature measurement, and the heat sink 1 were stacked in the same order as in Example 2 was fabricated. The heat sink and the phenolic plastic plate 4 are fastened with bolts so as to be in close contact, and the phenolic plastic plate 4 is placed on the lower side above the foamed styrene plate 8 . The same cooling fan 9 as in Example 2 (80 mm in length and 80 mm in width; manufactured by Sanyo Denki Co., Ltd.) was attached to the upper portion of the heat sink.

[0103] The heater 5 uses a 100V, 150W heater, does not change the external electric power of 84.75W (75V, 1.13A), and changes the speed of the fan 9 to 180...

Abstract

A radiating method using radiating fins, comprising the steps of stacking a coated metal layer (3) of a metallic material with an ionization tendency larger than that of silver on the surface of a radiating fin body (2) by plating, and radiating a heat from the coated layer (3) by allowing air as cooling fluid to come into contact therewith.

Description

technical field [0001] The present invention relates to a heat sink for heating elements such as electric products and electronic equipment, and more specifically, to a heat sink with a further improved heat dissipation effect and a heat dissipation method using the heat sink. Background technique [0002] Various radiators are used as heat sinks in order to prevent malfunctions and functional degradation due to heat generation in electrical products and electronic equipment such as televisions, computers, and motors, motor vehicle engines, radiators, and various mechanical devices. (heat sink). As a constituent material of the heat sink, metal materials such as aluminum and copper having good thermal conductivity are generally used. [0003] Various proposals have been made in the past as methods for improving the heat dissipation effect of such a heat sink. For example, as a method of increasing its heat dissipation area, there are aluminum anodized processing and shot b...
