Capsule-type heater device

A capsule-type heater device comprising:

• a first case including a first body having a hollow shape and thus provided with a first heat exchange space formed therein so as to pass a thermal medium including air therethrough, and a first coupling part provided at the center of the inside of the first body and integrated with the inner circumferential surface of the first body by a plurality of first connection parts, first heater mounting grooves being respectively formed in the first connection parts;
• a second case including a second body having a hollow shape and thus provided with a second heat exchange space formed therein so as to pass the thermal medium including air therethrough, and a second coupling part provided at the center of the inside of the second body and integrated with the inner circumferential surface of the second body by a plurality of second connection parts, second heater mounting grooves being respectively formed in the second connection parts, the second case having a symmetrical structure with the first case;
• and
• a heater including a heating part molded to have the same shape as the first and second cases and mounted in the first and second heater mounting grooves, and power connection ends provided at both ends of the heating part, the heater being installed within the first and second cases coupled so that the first and second cases are opposite each other under the condition that the heating part is mounted in the first and second heater mounting grooves,
• wherein, as the thermal medium including air passes through the first and second heat exchange spaces under the condition that the heater is installed between the first and second cases, the thermal medium contacts the heater and the cases heated by the heater and thus executes heat exchange.
