Abstract

Proposed is a heat dissipating device using turbulent flow. In the heat dissipating device, a plurality of block flow paths are formed in parallel inside a block body, a first cap and a second cap are mounted on side surfaces of the respective ends of the block body so as to connect the block flow paths, a working fluid flows into the block flow paths, and the working fluid which has passed through the block flow paths is transferred to the outside. Turbulence generators are mounted inside the block flow paths, and finishing end portions on the respective ends of the turbulence generators are supported by the first cap and the second cap and are positioned inside the block flow paths.

First claim

The invention claimed is:

1. A heat dissipating device using turbulent flow, the device comprising:
a block body in which a plurality of block flow paths through which a working fluid flows are formed side by side;
a first cap coupled to a side surface formed at a first end of the block body, and in which a connection flow path connecting between the block flow paths is formed;
a second cap coupled to a side surface formed at a second end of the block body, and in which connection flow path connecting between the block flow paths is formed; and
a turbulence generator installed inside the block flow paths to make a flow of the working fluid turbulent, with finishing end portions formed at opposite ends thereof being supported by the first cap and the second cap.

2. The heat dissipating device using turbulent flow of claim 1 , wherein the first cap and the second cap are provided with inlet/outlet flow paths through which the working fluid enters and exits the block flow paths.

3. The heat dissipating device using turbulent flow of claim 2 , wherein hanging ends at which the finishing end portions of the turbulence generator are supported by the first cap and the second cap function as edge regions of the inlet/outlet flow paths and the connection flow path formed in the first cap, and of the inlet/outlet flow paths and the connection flow paths formed in the second cap.

4. The heat dissipating device using turbulent flow of claim 3 , wherein the turbulence generator has a cylindrical coil spring shape and has an outer diameter smaller than an inner diameter of each of the block flow paths, and an outer diameter of each of the finishing end portions of the turbulence generator is formed to be larger than a diameter of a circular region in which the hanging ends are formed.

5. The heat dissipating device using turbulent flow of claim 4 , wherein a number of turns of the cylindrical coil spring formed at each of the finishing end portions is more than two.

6. The heat dissipating device using turbulent flow of claim 2 , wherein the inlet/outlet flow paths are connected to inlet/outlet connection pipes.

7. The heat dissipating device using turbulent flow of claim 1 , wherein each of the connection flow path formed in the first cap and the connection flow paths formed in the second cap has a curved inner surface.

8. The heat dissipating device using turbulent flow of claim 1 , wherein a seal is positioned between the first cap and the side surface of the block body or the second cap and the side surface of the block body, a seal groove in which the seal is located is formed on either side of the first cap or the side surface of the block body, or on either side of the second cap or the side surface of the block body.
