Abstract
A fluid-heating device for heating fluid with a heater includes: a heating portion that is molded so as to cover the surrounding of the heater; and a support body integrally cast into the heating portion, the heating portion being molded in a state in which the heater is supported by the support body in a die for molding the heating portion.
Claims16
A fluid-heating device for heating fluid with an electrically-powered heater having a helical-shaped heat generating part, the fluid-heating device comprising:
- a heating cover portion that is molded so as to cover the surrounding of the electrically-powered heater, the heating cover portion includes an outer wall portion configured to perform heat exchange with the heating fluid, the heater being integrally die-cast molded into the heating cover portion;
- and
- a support body integrally cast into the heating cover portion while supporting the helical-shaped heat generating part, the heating cover portion being integrally die-cast molded using a die in which the heater is supported by the support body,
- the support body including a first side and a second side opposite the first side, the first side contacting the helical-shaped heat generating part, and the second side including a pin hole extending into the second side, the second side being configured to perform heat exchange with the heating fluid.
A fluid-heating device for heating fluid with an electrically-powered heater, the fluid-heating device comprising:
- the electrically-powered heater including a helical-shaped heat generating part;
- a heating cover portion configured to surround the heater, the heating cover portion includes an outer wall portion configured to perform heat exchange with the heating fluid;
- and
- a support body configured to support the helical-shaped heat generating part,
- wherein the heater and the support body are integrally die-cast molded east into the heating cover portion while the support body supports the helical-shaped heat generating part,
- the support body contacting the helical-shaped heat generating part on a first side of the support body, and having a pin hole extending into a second side of the support body opposite to the first side, the second side being configured to perform heat exchange with the heating fluid.
