Plastic heat exchanger

摘要

A heat exchanger (10) comprises a plurality of plastic cooling tubes (16) extending between a first end plate (12) and a second end plate (14) and a baffle (24) arranged in the heat exchanger (10) and extending at least partially between the first end plate (12) and the second end plate (14). The baffle (24) comprises a plurality of first openings (26) for receiving a respective plastic cooling tube (16), the baffle (24) further comprising a plurality of second openings (28) arranged between the first openings (26). The second openings (28) permit air to flow through the heat exchanger (10) whilst creating turbulence in the air flow which increase the thermal transfer between the air and the tubes (16) increasing the efficiency of the heat exchanger (10).
