Abstract: A heat exchange device includes: a case, a fan provided inside the case and having a fan air outlet and a fan air inlet, a heat exchange element provided inside the case, a case air port formed in the case, and an adapter connected to the case air port at one end thereof, the adapter including more than one pipe connecting portions with different diameters, the pipe connecting portion closest to the case air port being a first pipe connecting portion, the pipe connecting portion farthest from case air port being a second pipe connecting portion; the diameter of the first pipe connecting portion is larger than the diameter of the second pipe connecting portion, and a thermal insulation component is provided in the adapter and has an air passage therein for passing air therethrough. The disclosure is advantageous in preventing occurrence of condensation and improving product safety.

Abstract: A ventilating device includes a frame forming an outer contour, an airflow path formed by a flowing of air inside the frame, and a plurality of orifices configured to measure a static pressure in a chamber where the airflow path is located, wherein at least one orifice of the plurality of orifices is further configured to drain water out of the frame. In the present disclosure, the orifice for static pressure measurement is provided in the air supply path and/or the air discharge path at a position where the dew is dominantly accumulated, the drainage function and the function of measuring the static pressure may be realized simultaneously, reducing the cost and ensuring air tightness.

Abstract: A filter mounting structure, includes a casing including upper, lower, front, back, left and right side panels and a filter unit. The filter unit includes a filter, a first support frame located at a front end of the filter, and a second support frame located at a side of the filter. The filter is mounted on the first and second support frames. A first mounting port is provided in the front side panel and a second mounting port is provided in any one of the left and right side panels. A mounting space is included in the casing and extends toward the first and second mounting ports respectively. The first support frame is mounted on the front side panel of the casing through the first mounting port and the second support frame is mounted on the left or right side panel of the casing through the second mounting port.

Abstract: A wire detachment-preventing structure includes: a circuit board box, a housing provided with a wiring outlet and constituting the circuit board box, a terminal block for connecting a wire and provided on the circuit board box and provided with a wiring inlet; the circuit board box is provided with a wire detachment-preventing rib, the wiring inlet and the wiring outlet are provided on one same side of the wire detachment-preventing rib, a first passageway is formed between the wiring outlet and the wire detachment-preventing rib, a second passageway is formed between the wire detachment-preventing rib and the housing, and the wire from the wiring outlet bypasses the wire detachment-preventing rib through the second passageway and leads to the wiring inlet through the first passageway so as to form a U shape. By use of the wire detachment-preventing rib, the wire is not easily detached from the wiring inlet.
