Benefits of technology

The invention is a heat exchanger for a ventilation apparatus that improves the strength of the combined elements. It is also easy and fast to insert into the housing of the ventilation apparatus.

Problems solved by technology

Furthermore, it is also inconvenient for the heat exchanger 92 to be disposed into the housing 91 in manufacture of the conventional ventilation apparatus 9 because the assembled heat exchanger 92 can be loose again before a combination between the housing 91 and the heat exchanger 92 is secured.

Embodiment Construction

[0038]Referring to FIGS. 2 and 3, a preferable embodiment of a heat exchanger of ventilation apparatus includes two positioning disks 1, a fixing module 2 for fixing the relative positions of the two positioning disks 1, and a plurality of guiding pipes 3 extending between the positioning disks 1.

[0039]Each of the two positioning disks 1 has a fixing portion 11 and a plurality of positioning portions 12, with the fixing portion 11 of one of the positioning disks 1 aligning with the fixing portion 11 of the other positioning disk 1, and with the positioning portions 12 of one of the positioning disks 1 respectively aligning with the positioning portions 12 of the other positioning disk 1. Besides, there can also be other fixing portions 11 in each positioning disk 1 if an enhanced structural strength is necessary. The fixing portion 11 is in a form for coupling with the fixing module 2, such as a groove, a pin, a fixing hole or a blind hole. Similarly, each positioning portion 12 is ...

Abstract

A heat exchanger of a ventilation apparatus including a first positioning disk, a second positioning disk, a fixing module and a plurality of guiding pipes is disclosed. The first positioning disk has a first fixing portion and a plurality of first positioning portions. The second positioning disk has a second fixing portion and a plurality of second positioning portions. The fixing module connects with the first and second fixing portions of the first and second positioning disks to separate the first and second positioning disks by a distance. The plurality of guiding pipes is arranged between the first and second positioning disks. A first end of each guiding pipe couples with a respective one of the first positioning portions of the first positioning disk, and a second end of each guiding pipe couples with a respective one of the second positioning portions of the second positioning disk.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to a heat exchanger of a ventilation apparatus and, more particularly, it relates to a heat exchanger able to be conveniently and firmly assembled inside the ventilation apparatus.[0003]2. Description of the Related Art[0004]Referring to FIG. 1, a United Kingdom patent, entitled as “Heat Recovery Ventilation Device,” with patent number of GB2452927B is shown. The patent discloses a conventional ventilation apparatus 9 which includes a housing 91, a heat exchanger 92, an air guiding lid 93, and a fan 94. The heat exchanger 92 is received inside the housing 91, which has two end disks 921 and a plurality of pipes 922 connecting to said two end disks 921, wherein each of the two end disks 921 has a plurality of positioning holes 923 for respective ends of the pipes 922 to be inserted therein. The air guiding lid 93 and fan 94 are mounted on an end of the housing 91. Therefore, with a...
