Abstract:
1. A heat exchanger of a plate type comprising an evaporator having at least one inlet and at least one outlet allowing a first medium to enter into and exit from said evaporator, wherein said evaporator comprises a plurality of interconnected evaporation chambers disposed in parallel, having at least one common inlet and at least one common outlet allowing the first medium to enter into and exit from said evaporation chambers, wherein an injector is provided in at least one of the evaporation chambers, said injector comprising a channel, a first opening at one end of the channel being fluidly connected with the common inlet of the evaporation chamber and a second opening at the other end of the channel being fluidly connected with an expanded outlet which opens to the evaporation chamber, the channel being much narrower than the common inlet so as to form a jet flow when the first medium flows through the channel, and a hole being formed on a sidewall of the channel at the intersecting point between the channel and the expanded outlet or formed on the sidewall of the channel near the intersecting point between the channel and the expanded outlet, wherein the evaporator is formed by a plurality of interacting alternating plates that are stacked together to form the plurality of interconnected evaporation chambers between the plurality of interacting alternating plates, and wherein at least two adjacent interacting alternating plates each have formed thereon at least one of a mating groove or a recess pattern configured to form the injector in at least one of the evaporation chambers when the at least two adjacent interacting alternating plates are mated together.
