Abstract

PROBLEM TO BE SOLVED: To make a radiator small in size by a method wherein a screw-shaped fin plate or a fin plate formed of a flat plate is disposed inside a main body and a passage is constructed by the fin plate. SOLUTION: Inside a main body 1 formed of a bottomed pipe, a communication passage 2 is provided in the bottom part and a screw-shaped fin 3 is inserted. The outer periphery of the fin 3 is brought into close contact with the inner wall of the main body 1 by subjecting the main body 1 to drawing and the inside of the main body 1 is so divided that passages (a) and (b) are formed. One passage (a) out of them is made to communicate with an inlet pipe 4 and the other passage (b) with an outlet pipe 5 and the upper end part of the main body 1 is sealed hermetically with a cap 6 so that a medium sent in from the inlet pipe 4 be made to flow through the passage (a) of the main body and made to run from the communication passage 2 to the outlet pipe 5 through the passage (b). The medium is subjected to heat exchange to be cooled down, by the fin plate 3 and the main body 1, while it flows through the main body 1. According to this constitution, a pitch of the passage can be lessened and a radiator can be made small in size.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator for cooling and heating by heat exchange using a medium such as a cooling device and a heating device.

[0002]

2. Description of the Related Art A heat exchange radiator conventionally used in a cooling device or the like uses a single thin tube and bends and bends this thin tube to form a pipe-like fin. They are arranged at intervals, and a medium is flowed through a thin pipe that is piped to perform heat exchange and cooling.

[0003]

In order to bend and meander a thin tube in the cooling device, a constant radius is required to bend the thin tube in order to bend and bend the thin tube alternately, and this radius must be the same. For example, the flow of the medium will be adversely affected. Therefore, there is a drawback in that the pipes are made with a constant pitch, and the size is increased.

[0004]

In view of such circumstances, the present invention addresses the above-mentioned problems by providing a communication passage at the bottom of a main body composed of a bottomed tube and inscribed with a fin plate. An inlet pipe for feeding the medium and an outlet pipe for the other are connected to one of the divided chambers and sealed by a cap so that the medium sent from the inlet pipe exchanges heat with the fin plate and the main body. To provide a radiator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a radiator according to the present invention. In the first embodiment of FIGS. Is provided with a communication passage 2 at the bottom, and a screw-shaped fin plate 3 is inserted and the main body 1 is drawn to bring the outer periphery of the fin plate 3 into close contact with the inner wall of the main body 1 to divide the inside of the main body 1. To form passages a and b.

One of the passages a and b is connected to the inlet pipe 4,
The other passage b is communicated with the outlet pipe 5, respectively, and the medium sent from the inlet pipe 4 flows through the passage a of the main body 1 and flows from the communication passage 2 through the passage b to the outlet pipe 5 by the cap 6. Part is sealed. Therefore, heat is exchanged between the fin plate 3 and the main body 1 while flowing through the main body 1 to be cooled.

FIG. 3 shows an embodiment in which another fin plate 3 is changed from a screw-shaped one to a flat plate-shaped one, and this fin plate 3'is inserted in the central portion so that both edges are formed into a main body. The main body 1 is in close contact with the inner wall of 1, and the main body is divided into two parts to form passages a and b.

[0008]

As described above, according to the present invention, the pitch can be reduced unlike the prior art by disposing the screw-shaped fin plate or the fin plate made of a flat plate in the main body and forming the passage by the fin plate. Therefore, the size can be reduced. Also, just insert the fin plate in the main body,
The structure is simple and can be inexpensive.
