With reference to these drawings, the present embodiment differs from the embodiment of FIG. 2 in that the bypass chamber 67 is provided adjacent to the side surface of the heat exchanger 2,
Further, the damper 68 that selectively opens the opening 16a and the opening 67b described later is provided. The bypass chamber 67 has a substantially triangular prism shape, has an opening 67a facing the exhaust side suction port 4A on the lower surface, and an opening 67b communicating with the exhaust fan chamber 14 on the end surface 670.

From the cross section of the main body 1, the area of the end face 670 is
The heat exchanger 2 has a width that is approximately ½ of the remaining portion of the heat exchanger 2 minus the cross section, which is approximately twice the width of the conventional one. Therefore, a very wide area can be secured as the opening 67b formed in the wide end surface 670 and communicating with the exhaust fan chamber 14. As a result, the pressure loss in the bypass air passage E2 can be reduced and the noise can be reduced. There is no need to upsize the main body 1 or narrow the cross section of the heat exchanger 2. Since the bypass chamber 67 is arranged on the side surface of the heat exchanger 2, the length of the main body 1 along the longitudinal direction of the heat exchanger 2 is shortened to further reduce the size of the heat exchange ventilation device A, or The length along the longitudinal direction of the exchanger 2 can be increased to improve the heat exchange capacity.

According to the invention of claim 1, since the bypass chamber provided adjacent to the end surface of the heat exchanger has a wide end surface which is not restricted by the cross section of the heat exchanger, A very large area can be secured as an opening formed in the end surface of the bypass chamber and communicating with the exhaust fan chamber. As a result, it is possible to reduce pressure loss in the bypass air passage and reduce noise. There is no need to upsize the main body or narrow the cross section of the heat exchanger.

According to the second aspect of the present invention, the bypass chamber provided adjacent to the side surface of the heat exchanger has a width substantially equal to the distance between the side surface of the main body and the side surface of the heat exchanger opposite thereto. The end surface has a height substantially equal to the total height of the heat exchanger. The area of this end face is approximately half the size of the remaining portion of the main body cross-section minus the cross section of the heat exchanger, and is approximately twice as wide as the conventional one. Therefore, a very large area can be secured as the opening formed in this wide end face and communicating with the exhaust fan chamber. As a result, it is possible to reduce pressure loss in the bypass air passage and reduce noise. There is no need to upsize the main body or narrow the cross section of the heat exchanger. Since there is no bypass chamber on the end face side of the heat exchanger,
Accordingly, the length of the main body can be shortened to downsize the heat exchange ventilation device, or the length of the heat exchanger can be lengthened to improve the heat exchange capacity.
