Abstract

Provided are a cooling flow channel module for a power conversion device, in which a structure of a cooling flow channel for cooling a power conversion device including an inverter or an LDC is simplified to facilitate manufacturing and assembling, and a power conversion device including the same. The cooling flow channel module includes an intake flow channel, a discharge flow channel disposed to be parallel to the intake flow channel, and a cooling pipe configured to connect the intake flow channel and the discharge flow channel and cool the heating element disposed thereabove or therebelow, wherein a plurality of cooling pipes are provided and connect a side portion of the intake flow channel and a side portion of the discharge flow channel disposed to be parallel to each other.

First claim

What is claimed is:

1 . A cooling flow channel module installed in a power conversion device to cool a heating element constituting the power conversion device, the cooling flow channel comprising:
an intake flow channel; a discharge flow channel disposed to be parallel to the intake flow channel; and a cooling pipe configured to connect the intake flow channel and the discharge flow channel and cool the heating element disposed thereabove or therebelow, wherein a plurality of cooling pipes are provided and connect a side portion of the intake flow channel and a side portion of the discharge flow channel disposed to be parallel to each other.

2 . The cooling flow channel module of claim 1 , further comprising:
a cooling plate disposed between the intake flow channel and the discharge flow channel, wherein the cooling pipes are disposed above and below the cooling plate.

3 . The cooling flow channel module of claim 2 , wherein the cooling plate includes installation recesses allowing the cooling pipes to be installed therein.

4 . The cooling flow channel module of claim 3 , wherein after the cooling pipes are inserted into the installation recesses, the cooling pipes are pressed to have a cross-sectional shape corresponding to the installation recesses.

5 . The cooling flow channel module of claim 4 , wherein the installation recesses have a quadrangular recess shape, and surfaces of the cooling pipes installed in the installation recesses, opposing the cooling plate and facing the heating element, are shaped to be flat.

6 . The cooling flow channel module of claim 1 , wherein the cooling pipes are welded to the intake flow channel and the discharge channel.

7 . A power conversion device including a cooling flow channel module, the power conversion device comprising:
an inverter unit configured to include a heating element; a converter unit configured to be disposed above or below the inverter unit and include a heating element; and a cooling flow channel module configured to be disposed between the inverter unit and the converter unit, wherein the cooling flow channel module includes: an intake flow channel; a discharge flow channel disposed to be parallel to the intake flow channel; and a cooling pipe configured to connect the intake flow channel and the discharge flow channel and cool the heating element disposed thereabove or therebelow, wherein a plurality of cooling pipes are provided and connect a side portion of the intake flow channel and a side portion of the discharge flow channel disposed to be parallel to each other.

8 . The power conversion device of claim 7 , further comprising:
a main housing; a first cover configured to cover any one of an upper portion and a lower portion of the main housing; and a second cover configured to cover the other of the upper portion and the lower portion of the main housing, wherein the main housing and the first cover form the inverter unit, the main housing and the second cover form the converter unit, and the cooling flow channel module is coupled to the main housing between the first cover and the second cover.

9 . The power conversion device of claim 8 , wherein
a through hole is formed in the main housing, the cooling flow channel module is coupled to the main housing in an upper portion of the through hole, and the heating element is disposed to be in contact with the cooling pipe above and below the cooling pipe.

10 . The power conversion device of claim 8 , wherein
the cooling flow channel module further includes a cooling plate disposed between the intake flow channel and the discharge flow channel, the cooling pipes are disposed above and below the cooling plate, and the cooling plate is coupled to the main housing.
