Heat exchanger and ventilator having the same

摘要

A heat exchanger usable with a ventilator, the heat exchanger having an improved structure so that air passing through the heat exchanger may be prevented from leaking. The heat exchanger of the general inventive concept includes a heat-exchanging element having a plurality of liners stacked in a uniformly spaced state and a plurality of spacers disposed between the liners to define air passages, and corner guides respectively coupled to corners of the heat-exchanging element. Each of the corner guides includes a guide channel forming a space to receive the corner of the heat-exchanging element so that the corner guides securely come into close contact with the heat-exchanging element, and to minimize a loosening of the corner guide due to an adhesive applied between the heat-exchanging element and the corner guide.

主权项

1. A heat exchanger, comprising:
a heat-exchanging element having a plurality of liners and a plurality of spacers disposed between the liners; covers respectively disposed at opposite ends of the heat-exchanging element; and corner guides respectively coupled to corners of the heat-exchanging element, wherein each of the corner guides comprises a guide channel forming a space between each corner of the heat-exchanging element and an inner surface of each corner guide, and contacts extended from both ends of the guide channel to contact adjacent sides of each corner of the heat-exchanging element, wherein the guide channel comprises a corner receiving portion into which each corner of the heat-exchanging element is inserted, and a fixing portion having a cylindrical space between the corner receiving portion and the inner surface of each corner guide to insert a fastener to secure each cover, the cylindrical space having a portion which is open to the corner receiving portion, and wherein each cover comprises flanges which cover outer sides of the corner guides so as to bring the corner guides into contact with the heat-exchanging element, and the contacts include, at outer surfaces thereof, stepped surfaces respectively formed so that the flanges can be mounted to the stepped surfaces respectively.
