Will be. Therefore, it is not necessary to provide a special partition for controlling the flow of the heat medium in the flow path 3 or to perform special processing on the heating wire heater 4.
- the opening size of the passage portion 43 and the cutout portion 41B on the inlet 13 side which is easy to flow due to the flow of the heat medium, is larger than the passage portion 42 and the cutout portion 41A on the outlet port 14 side. It is possible to make the flow of the heat medium in the passage 3 uniform, and to efficiently perform heat exchange between each heating wire heater 4 and the heat medium. As a result, the surface temperature of the heating wire heater 4 can be prevented from rising locally, and the life of the heating wire heater 4 can be extended. Further, in this embodiment, each heating wire heater 4 is disposed in each housing portion 6, 7, but since the gasket 8 is located between each heating wire heater 4, there is no problem between the housing portions 6, 7. It is also possible to realize control of the flow of the heat medium.
- the wall portion 9 of the gasket 8 is positioned in the flow path 3, that is, the flow path 3 is temporarily moved to the first housing portion 6 side and the second housing portion 7 side by the wall portion 9. Partitions, passage portions 11, 12, 15, 41 to 43 through which the heat medium passes are formed in the wall portion 9, and the flow of the heat medium is controlled by their opening size and shape.
- a part of the wall portion 9 of the gasket 8 may be positioned so as to protrude from the end surfaces of the housing portions 6 and 7 into the flow path 3. In that case, a portion other than a portion of the wall portion 9 of the overhanging gasket 8 serves as a passage portion.
- the projecting part may be inclined with respect to the flow direction of the heat medium so as to control the ease of flow. That is, the shape of the passage portion includes an inclination of a part of the wall portion 9 of the gasket 8 and the like.
- the number of heating wire heaters 4 and the number and shape of each passage portion of the gasket 8 are not limited to the above embodiments, and heating elements other than the heating wire heaters of the embodiments are applied as heating elements. It is also possible to use a fluid other than water as the heat medium. However, by using an inexpensive general-purpose heating wire heater 4, it is possible to reduce the manufacturing cost of the heating device 1 and to improve its reliability.
- the heating device 1 of the present invention into a vehicle air conditioner for a hybrid vehicle or an electric vehicle, it is possible to improve the performance of the air conditioner provided with the cooling water circuit and the vehicle in which the cooling water circuit is mounted. Needless to say, the heating device 1 can be used as a heat source for applications other than the vehicle air conditioner.
