Abstract

PURPOSE:To make the temperature of a panel uniform and to facilitate the mounting of equipments to the panel, by putting together a plurality of sandwich panel having heat pipes embedded in one direction with the heat pipes being arranged orthogonally. CONSTITUTION:A heat pipe embedded type sandwich panel comprises an upper sandwich panel 3-1 and a lower sandwich panel 3-2 that are put together, and heat pipes 5 are embedded in each of the panels 3-1, 3-2. In this arrangement, the heat pipes 5 in the panels 3-1, 3-2 are orghogonal. Therefore, the temperature of the panels 3-1, 3-2 can be made uniform, and since all the heat pipes 5 are embedded in the sandwich panels 3-1, 3-2, the degrees of freedom of the mounting of equipments 2 can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heat pipe-embedded sandwich panel that performs thermal control using heat pipes.

[Conventional technology]

Conventionally, heat pipe panels are devices that use heat pipes to uniformly distribute the heat generated over the entire surface of the panel and efficiently radiate heat from the radiator surface in order to optimally maintain the temperature of heat generating devices mounted on the panel. In order to increase the efficiency of heat radiation from the radiator surface, it is necessary to equalize the temperature of the panel.

Conventional heat pipe panels have structures as shown in FIGS. 2 to 4. In FIG. 2, the heat pipe panel includes an external heat pipe 1 provided on the surface of a sandwich panel 3 having front and back radiators 4, and a device 2 further provided thereon.

However, according to this method, the temperature difference between the front and back sides of the sandwich panel 3 increases, which deteriorates the heat dissipation efficiency of the radiator surface, and since the heat pipe 1 is placed outside the panel 3, the mounting space for the equipment 2 is restricted. Furthermore, since the heat pipes 1 are arranged in one direction, a temperature distribution occurs on the panel surface in a direction perpendicular to the heat pipes 1, resulting in a problem that the heat dissipation efficiency of the panel deteriorates.

FIG. 3 shows a structure in which the heat pipe 5 is embedded inside the sandwich panel 3. According to this, the second
Compared to the one shown in the figure, equipment mounting has been improved, and the temperature difference between the front and back of the panel 3 can be reduced.

However, as in the case of FIG. 2, since the heat pipe 5 is oriented in one direction, there is a problem in that a temperature distribution occurs in the panel 3.

Figure 4 shows a panel that is an improvement on the panels shown in Figures 2 and 3, in which a heat vibrator 1 is further attached externally to the outside of the panel 3 in which a heat vibrator 5 is embedded, thereby making the panel temperature uniform. I was able to convert it into

[Problems to be solved]

However, even with the configuration shown in FIG. 4, since the heat vibrator 1 is externally attached to the outer surface of the panel 3, there is a problem in that the mounting space for the device 2 is restricted as in the case of FIG. 2.

c. Solution to Problem] The present invention solves the above problem, and consists of a plurality of sandwich panels each having a heat pipe embedded in one direction so that each heat vibrator is orthogonal to each other in a plane. It is constructed by stacking layers.

〔Example〕 Next, an example thereof will be explained with reference to FIG.

FIG. 1 is a perspective view of an embodiment of the sandwich panel with embedded heat pipes according to the present invention, and FIG.
The same parts as in FIG. 3 are given the same reference numerals.

In the figure, the heat pipe embedded type sandwich panel has an upper sandwich panel 3-1 and a lower sandwich panel 3-2 stacked one on top of the other, and each panel 3-1, 3-2.
A heat pipe 5 is embedded in each trench.

In this case, the heat vibrator 5 of each panel 3-1, 3-2
are arranged perpendicular to each other. Therefore, temperature uniformity of the panels 3-1, 3-2 is achieved, and furthermore, the heat vibes 5 are all applied to the sandwich panels 3-1, .
Since it is embedded inside 3-2, the degree of freedom in mounting the device 2 is increased. A panel with such a structure can be applied to a heat pipe panel with high heat transfer characteristics.

〔effect〕

As explained above, the present invention is constructed by stacking a plurality of sandwich panels each having a heat pipe embedded in one direction in such a way that each heat vibrator is orthogonal to each other in a plane. The temperature can be made uniform, equipment can be easily mounted on the panel, and
Several types of unidirectional heat pipe panels are used as standard panels,
By appropriately selecting the combination, heat pipe panels can be standardized, which has the advantage of reducing costs and improving reliability.
