BOX-TYPE HEAT EXCHANGE DEVICE

A box-type heat exchange device, comprising a box body and heat exchange cores mounted in the box body. A heat exchange channel is formed in the box body, and comprises a plurality of first through holes penetrating the heat exchange cores. The box body comprises a first side plate provided with an indoor air supply port and an indoor air return port. One end of each of the first through holes is in communication with the indoor air supply port, and the other end thereof is in communication with the indoor air return port. According to the box-type heat exchange device of the present invention, the indoor air supply port and the indoor air return port are provided in the same side plate of the box body, such that the length of a duct from an indoor space to the box body can be effectively reduced, i.e., reducing the wind resistance of the duct. Therefore, the power consumption of a fan can be reduced. Dispositif d'échange de chaleur du type boîte comprenant un corps de boîte et des noyaux d'échange de chaleur
