Abstract

PURPOSE:To permit the carrying and accumulation of heat in a lengthwise direction substantially and uniformly in a long heat pipe by arranging heat accumulating material along the lengthwise direction of a heat pipe container. CONSTITUTION:An outer pipe 3, whose both ends are connected to the outer peripheral surface of an outer heat pipe container 2 sealingly excluding a heat absorbing and evaporating section A and a heat dissipating and condensing section B, is provided at the outside of the outer heat pipe container 2 and heat accumulating material 4 is sealed into the outer pipe 3. A temperature keeping layer 5, formed of vinyl chloride, polyethylene or the formed layer of these materials, is provided on the outer periphery of the outer pipe 3. The heat pipe container is formed so as to be double and, therefore, temperature reduction may be prevented in the heat transfer of a long distance and excellent heat transfer efficiency may be obtained. When heat pipe is utilized as the same to cope with a long distance and intermittent heat source or load, it may be very effective.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a particularly long heat pipe in which a heat pipe container has a double structure and a steaming material is provided on the outside of the heat pipe container.

(Prior Art and Problems to be Solved) Conventional heat pipes simply transfer heat, and when heat storage is required, a separate heat storage tank is provided. Therefore, if there is a change in the heat capacity (load) or temperature of the heat absorption or heat radiation part of the heat pipe, the change immediately affects the other end.

Additionally, in general, if the heat supply power is large and the heat dissipation load is small, the heat on the supply side is wasted, and it is particularly difficult to handle peak loads with long heat pipes.

Furthermore, in cases where the heat reception time is intermittent, such as in solar systems, and where heat is desired to be as stable as possible, heat pipes alone cannot be used unless a separate heat storage tank is installed.

(Means for Solving the Problems) The present invention provides a heat pipe that solves the above-mentioned problems and is particularly suitable for long-distance heat transfer, having a heat storage capacity. An outer heat pipe container is provided on the outside of the main heat pipe container, the end of which is hermetically connected to the outer peripheral surface of the main heat pipe container, and the inner space of which is filled with a working liquid. An outer pipe is provided with both ends sealed and connected to the outer circumferential surface of the outer heat pipe container, except for the heat dissipation and condensation part.
It is a heat pipe that has a heat storage material sealed inside it.

(Example) FIG. 1 is an explanatory diagram showing a vertical cross section of a specific example of the heat pipe of the present invention.

In the drawings, (1) is a main heat pipe container consisting of a sealed pipe made of copper, stainless steel, etc. with a working liquid such as water or methanol sealed in the internal space, and (2) is a main heat pipe container with the end section attached to the outside of the main heat pipe container. This is an outer heat pipe container made of the same metal material as the main heat pipe container (1), which is hermetically connected to the outer peripheral surface of the heat pipe and has a working liquid such as water or methanol sealed in the internal space, and (A)
(B) is an endothermic evaporation section, and (B) is a heat dissipation condensation section.

On the outside of the outer heat pipe container (2), an outer pipe (excluding the endothermic evaporation section (A) and the heat dissipation condensation section (B)) whose both ends are hermetically connected to the outer peripheral surface of the outer heat pipe container (2) is provided. 3), and inside it there is a heat storage material (4).
is included. On the outer periphery of the outer pipe (3),
A heat insulating layer (5) made of vinyl chloride, polyethylene, or a foamed layer of these is provided.

As the heat storage material, sensible heat storage materials such as water and gravel, and latent heat storage materials such as calcium chloride hexahydrate, sodium sulfate 1O hydrate, and high-density polyethylene are used.

(Effects of the Invention) As explained above, according to the heat pipe of the present invention,
Since the heat storage material is arranged in the longitudinal direction of the heat pipe container, it is possible to transport and store heat in the longitudinal direction, almost like a long heat pipe, and it does not take up much space, allowing efficient use of the heat storage material. .

Additionally, it has a smoothing effect against varying heat sources or loads, and can always respond to peak loads.

Furthermore, since the heat pipe container is double-layered, it prevents the temperature from decreasing during long-distance heat transfer.
Good heat transfer efficiency is obtained.

Therefore, the heat pipe of the present invention is extremely effective when used as a long-distance and intermittent heat source or as a heat pipe that can handle a load.
