Heat-exchange device

Abstract

The invention discloses a heat-exchange device which comprises a shell, a heat exchanger, an external wind supply fan and an internal wind circulating fan, wherein the heat exchanger is mounted in the shell, and an internal wind channel, an external wind channel and a communication channel are formed in the shell; an external wind heat exchange runner, a first internal wind heat exchange runner and a second internal wind heat exchange runner are formed on the heat exchanger; the external wind channel comprises an external wind inlet channel and an external wind outlet channel, and the external wind inlet channel is communicated with the external wind outlet channel through the external wind heat exchange runner; the internal wind channel comprises an internal wind inlet channel and an internal wind outlet channel, and the internal wind inlet channel is communicated with the wind inlet end of the communication channel through the first internal wind heat exchange runner; the internal wind channel is mutually isolated from the external wind channel. The heat-exchange device can avoid the mixing of external wind and internal wind, therefore can avoid impurities and foreign matters in the external wind to be mixed in the internal wind so as to ensure the cleanliness of the internal wind, and therefore the failure of cooled equipment can be reduced.

Description

Technical field [0001] The invention relates to a heat exchange device. Background technique [0002] Various equipment such as motors are prone to generate heat during operation, and the heat generated by them is often taken away by using internal wind to ensure that various equipment such as motors can work normally. Since the internal air takes away the heat of the equipment, the temperature will increase. In order to make the internal air recyclable, the heat exchange device generally exchanges heat with the external cold air flowing into it, so that the high-temperature internal air can be cooled. In order to facilitate the cooling of the internal air after cooling down into various equipment such as motors. Existing heat exchange devices generally include shells and heat exchangers, but in the working process, the phenomenon of mixing of internal air and external air is easy to occur, and because the external air is often mixed with impurities and foreign matter, which aff...
