Heat exchanger for use in housing i.e. switching cabinet, has nozzles via which partial air stream is directed, where partial air stream has flow rate higher than that of air flow directed in longitudinal direction of flow channel

摘要

The heat exchanger has a heat exchanging element (12.1) including heat-emitting and heat-absorbing sides. A flow channel (25) is formed by a channel cover (20) at the sides. Air flow is directed in a longitudinal direction of the flow channel. Nozzles (21) open out into the flow channel, where a partial air stream is directed via the nozzles. Flow direction of the partial air stream runs with respect to the nozzles, at an angle to flow direction of the air flow. The partial air stream has flow rate higher than that of the air flow.
