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 connected to and co-operating with the evaporator can be reduced.

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, anda 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, andwherein 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. 2. The heat exchanger according to claim 1, wherein the expanded outlet is a trumpet outlet. 3. The heat exchanger according to claim 1, wherein the injector is provided in each of the evaporation chambers. 4. The heat exchanger according to claim 1, wherein an additional hole is provided through which the evaporation chambers communicate with each other. 5. The heat exchanger according to claim 1, wherein the heat exchanger is formed of interacting alternating plates having a groove pattern forming at least two separate duct loop systems allowing the first medium (I) to circulate in the first of said duct loop systems under heat exchange with a second medium (II) circulating in the second of said duct loop systems, wherein said first duct loop system comprises a part forming said plurality of interconnected evaporation chambers. 6. The heat exchanger according to claim 5, wherein said interacting plates form a third duct loop system in which a third medium (III) circulates under heat exchange with at least said first medium (I). 7. The heat exchanger according to claim 6, wherein said evaporation chambers have one delimited zone (B″) defined, and the outlet of said evaporation chambers is connected, via a compressor, to a part of said first duct loop system forming a condenser chamber having a substantially vertical channel (C″) piloting said first medium (I) from said chamber's lower part up into another delimited defined zone (A″), wherein said first medium (I) can circulate in said two delimited zones (A″, B″) under heat exchange with itself. 8. The heat exchanger according to claim 1, wherein the heat exchanger comprises: a first duct chamber having an inlet and an outlet allowing a second medium (II) to enter said first duct chamber through said inlet to be piloted through said first duct chamber under heat exchange with said first medium (I), and to leave said first duct chamber through said outlet,said plurality of interconnected evaporation chambers having one delimited zone (B″), allowing said first medium (I) to enter through said common inlet to be piloted through said evaporation chambers under heat exchange with said second medium (II) and further through said delimited zone (B″) under heat exchange with itself, and to leave said evaporation chambers through said common outlet, and,a compressor and a condenser chamber having an inlet and an outlet, said condenser chamber further having another delimited zone (A″) and a substantially vertical channel (C″) leading to said another delimited zone (A″) from said condenser chamber's lower part, and said compressor being connected to said common outlet and said inlet, allowing said first medium (I) to be piloted from said common outlet into said condenser chamber through said inlet via said compressor and further piloted through said condenser chamber under heat exchange with a third medium (III), and further piloted up through said channel (C″) into and through said other zone (A″) through which said first medium (I) is allowed to be piloted under heat exchange with itself and thereafter to leave said condenser chamber through said outlet, and,an expansion valve connected to said outlet and said common inlet allowing said first medium (I) to be piloted from said condenser chamber into said evaporation chambers through said common inlet via said expansion valve, and,a second duct chamber having an inlet and an outlet allowing said third medium (III) to enter into said second duct chamber through said inlet and to be piloted through said second duct chamber under heat exchange with said first medium (I) and allowing said third medium (III) to leave said second duct chamber through said outlet. 9. A heat pump system, wherein the heat pump system comprises a heat exchanger according to claim 1. 10. An air condition system, wherein the air condition system comprises a heat exchanger according to claim 1.
