Abstract

<P>PROBLEM TO BE SOLVED: To provide a heating container for fluid, improved in heat transfer efficiency. <P>SOLUTION: The material quality and shape of the sides of the heating container and a radiating tool that come into contact with a heat source are changed to cause a difference in heat transferred to the heating container and the radiating tool, thereby accelerating convection in the vicinity of the container and the tool to heighten the heat transfer efficiency. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention relates to a fluid heating container that improves heat transfer efficiency.

In the conventional fluid heating container, the appearance shape mainly focusing on ease of use is emphasized. In some cases, heat is transmitted uniformly (see, for example, Patent Document 1), or a device for increasing the heat transfer area with an object to be heated is provided. (For example, see Patent Document 2)

Japanese Patent No. 2876396 Japanese Patent Publication No. 2003-93235

In the above prior art, since it was not considered to suppress the heat transmitted directly from the heat source to the atmosphere, the efficiency was poor.

The present invention intends to solve the problems of such a conventional configuration.

In the present invention, a convex shape is given to a part of the heat transfer container that is in contact with the object to be heated, or the same shape is placed.

As a second solution, a convex object or a material for promoting convection placed in a container is different from the material of the heated surface.

The action of the first problem solving means is to rectify the convection flow.

The action of the second solving means is to cause a temperature difference on the heated surface.

When the object to be heated is heated, a small amount of heat is required, and when it is intended to dissipate heat, heat can be dissipated in a short time.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

In the figure, 1 is a container for storing an object to be heated, 2 is a plurality of protrusions protruding toward the object to be heated, 3 is a surface that contacts the object to be heated, and 4 is a surface that is in contact with the heat source. 5 represents a state in which the two protrusions penetrate through the surface in contact with the heat source.

The operation of the above configuration will be described below. When the surface 4 is heated from the heat source, a temperature difference is caused by the difference in material and shape between 2 and 3 to promote convection, and the two protrusions adjust the convection flow. Similarly, by promoting convection between the protrusions on the side surface of the container and increasing the heating efficiency, the target temperature can be reached in a short time with a small amount of heat.

Claims (1)

A container having a protrusion, which is made of a material having a specific heat different from that of the material of the heated surface on the heated surface side of the heated surface, penetrates the heated surface or is fixed and placed on the heated object.
