Converter
A converter comprises: a housing; a plurality of heat generating elements arranged at one surface of the housing; and a fluid channel arranged at the other surface of the housing, wherein the fluid channel includes an inlet and an outlet which connect and pass through an outside and an inside of the housing, is formed by a single line from the inlet to the outlet, has a constant cross-sectional area, and is arranged at a position where the fluid channel overlaps the plurality of heat generating elements in a vertical direction.
1. A converter comprising:
a housing;
a plurality of heat generating elements disposed in the housing; and
a pipe disposed in the housing and including an inlet and an outlet,
wherein the pipe is formed in a tube shape with a constant cross-sectional area in a vertical direction from the inlet to the outlet,
wherein the pipe is disposed at a position overlapping with the plurality of heat generating elements in a vertical direction,
wherein the housing includes a fluid channel in which the pipe is disposed,
wherein the pipe is surrounded by the fluid channel except for the inlet and the outlet,
wherein the converter comprises a cover surrounding the fluid channel, and
wherein the housing includes a stepped portion formed corresponding to the shape of the fluid channel.
2. The converter according to claim 1 , wherein the pipe comprises:
a first straight portion extending horizontally from the inlet;
a first bent portion bent inwardly from an end portion of the first straight portion; and
a second straight portion extending horizontally from the end of the first bent portion.
3. The converter according to claim 2 , wherein
both ends of the pipe are exposed towards the outside of the housing from the inlet and the outlet.
4. The converter according to claim 2 , wherein
the pipe and the housing are integrally formed by an insert injection molding method.
5. The converter according to claim 1 , wherein
the cover is formed integrally with the housing and is the same material as the housing.
6. The converter according to claim 1 , wherein
a surface facing the heat generating elements of an inner circumferential surface of the fluid channel is a planar surface.
7. The converter according to claim 1 , wherein
the pipe has a plurality of linear portions and a plurality of bending portions connecting the linear portions, wherein
the flow rate of the refrigerant flowing through the linear portions is constant.
8. The converter according to claim 7 , wherein
the bent portions are arranged opposite to a region facing the heat generating elements.
9. The converter according to claim 1 , wherein the pipe includes a flat portion and a curved portion, and
the flat portion is disposed on an outer surface of the pipe facing the heat generating element.
10. The converter according to claim 1 , wherein the plurality of heat generating elements include a transformer and an inductor.
11. The converter according to claim 1 , wherein a heat dissipation fin is disposed on a side of the housing.
12. The converter according to claim 1 , wherein through-holes are formed on side surfaces of the housing to protrude both ends of the pipe.
13. The converter according to claim 1 , wherein the housing includes a plurality of heat dissipation fins protruding from an area other than the stepped portion.
14. A converter comprising:
a housing;
a plurality of heat generating elements disposed in the housing; and
a pipe disposed in the housing and including an inlet and an outlet,
wherein the pipe is formed in a tube shape with a constant cross-sectional area in a vertical direction from the inlet to the outlet,
wherein the housing includes a fluid channel in which the pipe is disposed,
wherein the pipe is surrounded by the fluid channel except for the inlet and the outlet, and
wherein the pipe and the housing are integrally formed by an insert injection molding method.
15. The converter according to claim 14 , wherein the pipe is exposed to the outside of the housing at the inlet and the outlet.
16. The converter according to claim 14 , wherein
the housing includes a stepped portion formed corresponding to the shape of the fluid channel.
17. The converter according to claim 16 , wherein the housing includes a plurality of heat dissipation fins protruding from an area other than the stepped portion.
