害要因となるものである。Problems to be Solved by the Invention This conventional device has a blowing function and a heat exchange function in the blade portion, but the air flow is
It is sucked in in the axial direction of the impeller, then flows along the blade portion, is changed direction at the outer circumferential portion, and is discharged in the axial direction. Since the direction of the flow is changed in this way, the blowing loss is large, and therefore the heat exchange efficiency on both sides of the blade portion becomes insufficient. Furthermore, since the air is sucked in and discharged in the axial direction, the discharged fluid may be sucked in, which adversely affects the heat exchange function. Furthermore, considering the part where this conventional blower is incorporated into equipment, air is sucked in axially and discharged axially, so a gap must be created in the axial direction between the impeller and the casing in order for air to be discharged. This is an impediment to making the device thinner and smaller.

のである。Effects of the Invention As is clear from the above embodiments, the heat exchange type blower of the present invention is particularly advantageous in that the blade portion of the impeller is formed into a wave shape having radial grooves that serve as air passages on both sides, and In the thickness direction, the area between the inner support part and the outer support part and from both support parts to the corner part at the end of the inner and outer circumference of the groove was airtightly closed with the closing member, so that the area near the center of both sides of the impeller The air sucked into the blade flows through the grooves on both sides of the blade, exchanging heat, and then being discharged toward the outer periphery, resulting in smooth air flow, less air loss, and higher efficiency. Heat exchange is often carried out. In addition, unlike the conventional method, when the exhaust air is sucked in, the heat exchange efficiency is extremely high. Since the exhaust is directed toward the outer periphery, there is no need for a gap in the axial direction when the device is installed in equipment, which is the case in the past, and this greatly contributes to making the equipment thinner and smaller.

るものである。 Furthermore, although the impeller does not have a closed shape on the entire inner and outer periphery of the blade, the corners of the blade are airtightly closed with a closing member, so the impeller is strongly supported and prevents deformation of the blade. It can sufficiently perform the functions of air prevention, ventilation, and heat exchange.
