METHOD FOR PRODUCING A HEAT EXCHANGER AND RELEVANT HEAT EXCHANGER

摘要

The invention relates to a method for producing a heat exchanger, wherein at least one microchannel, placed within a plate having an upper face and a lower face and precisely arranged between said upper face and lower face is obtained by making a groove on the upper face of the plate, said groove extending between an open extremity facing on the upper face and a blind extremity placed inside the plate, and machining the blind extremity of the groove to create a volume of a suitable size to house a tube inserted in the microchannel, said tube being fixed inside the microchannel by generating an interference between the tube and the microchannel. The invention relates also to a heat exchanger obtained by such method.

1. Method for producing a heat exchanger, comprising the steps of:
making at least one microchannel within a plate having an upper face and a lower face, said microchannel extending inside the plate between the upper face and the lower face, inserting a tube inside the microchannel and generating interference between the tube and the microchannel so as to fix the tube inside the microchannel, wherein the microchannel is made according to the following steps: a) making a groove on the upper face of the plate, said groove extending between an open extremity facing on the upper face and a blind extremity placed inside the plate, b) machining the blind extremity of the groove to create a volume of a suitable size to house the tube.
