Abstract
A drum type heat exchanger for effectively ventilating and purifying room air of a factory, a building or a house and the like is described. The drum type heat exchanger has heat transfer means with a drum shape and thus an entire size is reduced as much as possible and become compact, such that a handling and an installation is easy, a thermal efficiency to an installation space of the heat transfer means is maximized, and overall maintenance and repair such as a check or exchange of the heat transfer means are easy. Additionally, the drum type heat exchanger uses a drum with a short radius of rotation so that an entire operation cycle time is shortened and a heat transfer area is sufficiently secured in order to keep the thermal efficiency high.
Claims5
A drum type heat exchanger comprising:
- a main body having an outer air outlet and an inner air inlet formed at a front panel thereof and an outer air inlet and an inner air outlet formed at both side panel respectively, the main body having an outer air chamber and an inner air chamber defined by dividing an inner space thereof with a blocking plate disposed in a length direction so as to enable indoor air and outdoor air to flow out of and flow into the room;
- a heat transfer drum disposed over both chambers along a length direction thereof in the main body and rotatable with both ends thereof being supported by a plurality of rollers, the heat transfer drum performing heat exchange between the indoor and outdoor air by traveling both chambers during rotation;
- a driving motor located at one side in the main body and rotating the heat transfer drum connected therewith by a belt wherein the heat transfer drum comprising:
- a drum body having roller guide surfaces formed continuously along circumferences of both ends thereof and a pulley formed at a middle portion thereof, the drum body formed to be a porous meshed cylinder;
- a heat transfer medium attached to an entire circumferential surface of the drum body with a fixed thickness and performing the heat exchange with the air.
