Abstract
Disclosed is 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 the evaporator. The 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 the evaporation chambers. An injector (495) is provided in at least one of the evaporation chambers, the injector comprises a channel, the channel is connected at one end with the common inlet of the evaporation chamber and is connected at the other end with an expanded outlet which opens to the evaporation chamber, the channel is much narrower than the common inlet so as to form a jet flow when the first medium flows through the channel, and a hole (180, 480) is formed at the intersecting point between the channel and the expanded outlet or formed on the channel near the intersecting point between the channel and the expanded outlet. With the technical solution of the invention, the efficiency of the evaporator and thus the heat exchanger can be improved, and the wear of a compressor…
