| 摘要 |
The invention relates to a heat exchanger (1) or chiller (2), comprising a heat exchanger block (3) having a first fluid channel (6) for a coolant and a second fluid channel (7) for a refrigerant (5), an expansion valve for controlling a mass flow rate of the refrigerant (5), a connection flange (8) having an inlet channel (9) and an outlet channel (10) for the refrigerant (5), wherein the inlet channel (9) is connected to the second fluid channel (7) in an transition region (11). It is essential to the invention that the expansion valve is designed as an electronic expansion valve (13), that the connection flange (8) has an insertion opening (12), which communicates with the transition region (11) of the inlet channel (9), into which insertion opening the expansion valve (13) is inserted in such a way that the expansion valve controls a mass flow rate of the refrigerant (5) in the transition region (11) and evaporation of the refrigerant (5) first occurs in the second fluid channel (7) of the heat exchanger/chiller (1, 2). |
