Abstract
The invention relates to a wall air conditioning apparatus for a control panel, with a fan and a lamellar heat exchanger, featuring a box-like housing with an upper inlet opening and a lower outlet opening in the wall that faces the control panel, whereby the fan is arranged behind the inlet opening and the lamellar heat exchanger is arranged under the fan and over the outlet opening at an acute angle to this wall. For improved ventilation and drainage of condensation water, it is provided that the lamellae of the lamellar heat exchanger are at an acute angle to the floor of the housing and drop off toward the wall that faces away from the control cabinet, and that the floor of the housing is provided with a drain for condensate.
Claims6
A cooling apparatus for a control panel comprised of:
- a housing having a first side wall facing toward the control panel, a second side wall facing away from the control panel and upper and lower panels spaced from one another and extending between the first and second side walls;
- an upper inlet opening and a lower outlet opening in the side wall facing the control panel;
- a fan supported by the side wall facing away from the control panel and in registry with the upper inlet opening;
- a condensation drain located in the lower panel;
- and
- a heat exchanger between the fan and the lower outlet opening and having a plurality of lamella, each having a horizontal front edge facing the control panel and a rear edge facing away from the control panel each lamellae of the plurality of lamella being in a plane positioned at an acute angle with respect to the lower panel and extending laterally between the side walls,
- thereby allowing moisture condensing on the lamella to gravity-drain away from the front edge and toward the rear edge of the lamella in the direction of the air flow across the heat exchanger.
