Abstract: An evaporator is fabricated from metal pipes bundled together by cooling fins. The pipes have their ends embedded in a curable plastic securing them to a plastic collecting box. The collecting box has a distributing section with a plurality of injection orifices and return orifices flowing respectively into injection chambers and return flow chambers. The injection chambers merge into an injection collecting chamber and the return flow chambers merge into a return collecting chamber. A plastic connecting section has an integral injection pipe and return pipe and is connected to the distributor pipe by a tongue and groove connection sealably secured together by a curable plastic. The injection pipe and return flow pipe are in fluid communication with the injection collecting chamber and return collecting chamber respectively.
