Abstract

A fluid heating heater according to one embodiment of the present invention may include a main body in which a flow path through which a fluid flows in and is heated is formed, an inlet that is disposed on one side of the main body and through which the fluid flows in, an outlet that is disposed on the other side of the main body and through which the fluid flows out, and a plurality of flow path protrusions that are provided inside the main body to protrude and are isotropically disposed between the inlet and the outlet.

First claim

What is claimed:

1 . A fluid heating heater comprising:
a main body in which a flow path through which a fluid flows in and is heated is formed; an inlet that is disposed on one side of the main body and through which the fluid flows in; an outlet that is disposed on the other side of the main body and through which the fluid flows out; and a plurality of flow path protrusions that are provided inside the main body to protrude and are isotropically disposed between the inlet and the outlet.

2 . The fluid heating heater of claim 1 , wherein the main body includes:
a main plate including the flow path protrusions on a surface thereof; and a cover coupled to cover an upper portion of the main plate.

3 . The fluid heating heater of claim 2 , wherein the inlet and the outlet are symmetrically disposed on both sides centered on the main plate.

4 . The fluid heating heater of claim 2 , wherein an upper end of the flow path protrusion is formed to be spaced apart from the cover.

5 . The fluid heating heater of claim 2 , wherein the flow path protrusions are disposed in a plurality of columns and rows on the main plate.

6 . The fluid heating heater of claim 5 , wherein the flow path protrusions disposed in the same column and row among the flow path protrusions are disposed at a constant interval.

7 . The fluid heating heater of claim 5 , wherein the flow path protrusion is disposed between the flow path protrusions disposed in a next adjacent row or column.

8 . The fluid heating heater of claim 2 , wherein the flow path protrusion is formed to have a rhombus-shaped cross-section.

9 . The fluid heating heater of claim 8 , wherein the flow path protrusion is disposed so that a rhombus-shaped diagonal line lies in a flow direction of the fluid on the main plate.

10 . The fluid heating heater of claim 2 , wherein the flow path protrusion is formed to have an elliptical cross-section.

11 . The fluid heating heater of claim 2 , wherein the flow path protrusion is formed so that a height thereof increases toward the outlet from the inlet.

12 . The fluid heating heater of claim 2 , wherein a height thereof increases in some sections toward the outlet from the inlet.

13 . The fluid heating heater of claim 2 , wherein a heating element is mounted on a lower surface of the main plate to transfer heat to the main plate.

14 . The fluid heating heater of claim 13 , wherein the heating element is disposed closer to the inlet than the outlet with respect to a flow direction of the fluid.

15 . A fluid heating heater comprising:
a main plate in which a flow path through which a fluid flows in and is heated is formed; an inlet that is disposed on one side of the main plate and through which the fluid flows in; an outlet that is disposed on the other side of the main plate and through which the fluid flows out; and a flow path protrusion that is provided inside the main plate to protrude and is disposed between the inlet and the outlet so that a surface area thereof increases toward the outlet from the inlet.

16 . The fluid heating heater of claim 15 , wherein the flow path protrusion is formed so that a size thereof decreases toward the outlet from the inlet.

17 . The fluid heating heater of claim 15 , wherein the flow path protrusions are disposed so that the number thereof increases toward the outlet from the inlet.

18 . The fluid heating heater of claim 15 , wherein the flow path protrusions are disposed so that an interval therebetween becomes narrower toward the outlet from the inlet.

19 . The fluid heating heater of claim 15 , wherein the flow path protrusion includes:
a first flow path protrusion disposed between the inlet and a central portion of the inlet and the outlet; and a second flow path protrusion disposed between the central portion and the outlet, and the first flow path protrusion is formed to have a larger size than the second flow path protrusion.

20 . The fluid heating heater of claim 19 , wherein the first flow path protrusions are disposed to have a narrower interval than the second flow path protrusions.
