Abstract

A heating element accommodation case, comprising a casing to accommodate a heating element, the casing having a flow channel configured for a liquid to flow through, a portion of the flow channel being formed of a resin; and a heating element accommodation case, comprising a casing to accommodate a heating element and an airflow channel configured for air to flow through.

First claim

1 . A heating element accommodation case, comprising a casing to accommodate a heating element, the casing having a flow channel configured for a liquid to flow through, a portion of the flow channel being formed of a resin.

2 . The heating element accommodation case according to claim 1 , wherein the casing has a metal portion that includes a metal.

3 . The heating element accommodation case according to claim 2 , wherein the metal portion has, at at least a part of a surface of the metal portion, a concave-convex structure that is formed by a roughening process.

4 . The heating element accommodation case according to claim 2 , wherein the casing further has a resin portion that includes a resin, and the metal portion has a concave-convex structure at a portion to be joined to the resin portion.

5 . The heating element accommodation case according to claim 2 , wherein at least a part of the metal portion is disposed at a position configured to contact the heating element.

6 . The heating element accommodation case according to claim 1 , wherein at least a part of a portion surrounding a space through which a liquid flows in the flow channel is formed of a resin.

7 . The heating element accommodation case according to claim 6 , wherein at least a part of a portion surrounding a space through which a liquid flows in the flow channel is formed of a metal.

8 . The heating element accommodation case according to claim 1 , wherein the flow channel is disposed at at least one of a base portion, an upper portion or a side portion of the heating element.

9 . The heating element accommodation case according to claim 8 , wherein the flow channel is disposed at at least an upper portion of the heating element.

10 . The heating element accommodation case according to claim 8 , wherein the flow channel comprises a first flow channel disposed at a base portion of the heating element and a second flow channel disposed at an upper portion of the heating element, and one of the first flow channel or the second flow channel adjusts a temperature of a terminal of the heating element and the other of the first flow channel or the second flow channel adjusts a temperature of a main body of the heating element.

11 . The heating element accommodation case according to claim 8 , wherein the flow channel comprises a first flow channel disposed at a base portion of the heating element and a second flow channel disposed at an upper portion of the heating element, and one of the first flow channel or the second flow channel cools the heating element and the other of the first flow channel or the second flow channel warms the heating element.

12 . The heating element accommodation case according to claim 1 , wherein at least one flow channel is disposed near a high-heating portion of the heating element.

13 . A heating element accommodation case, comprising a casing to accommodate a heating element and an airflow channel configured for air to flow through.

14 . The heating element accommodation case according to claim 13 , wherein the airflow channel is isolated from a space in which the heating element is accommodated.

15 . The heating element accommodation case according to claim 13 , which is installed in a mobile object.

16 . The heating element accommodation case according to claim 13 , wherein the airflow channel is configured for air to flow along a direction in which the mobile object moves.

17 . The heating element accommodation case according to claim 13 , wherein air is caused to flow through the airflow channel by a blower.

18 . The heating element accommodation case according to claim 13 , wherein at least a part of the airflow channel is formed of a metal.

19 . The heating element accommodation case according to claim 18 , wherein at least a portion of the airflow channel that contacts the casing is formed of a metal.

20 . The heating element accommodation case according to claim 19 , wherein the casing has a vent that communicates an inside of the casing with an outside of the casing.

21 . A structure, comprising the heating element accommodation case according to claim 1 , and a heating element that is accommodated in the heating element accommodation case.

22 . The structure according to claim 21 , wherein the heating element is at least one selected from the group consisting of a secondary battery module, an electronic component device, and a power conversion device.
