HEAT EXCHANGER WITH LAMINARIZER
The invention relates to a heat exchanger which enables an efficient and uniform cooling and/or heating of liquids, in particular of blood. This exchanger is intended namely for use in medicine. The heat exchanger comprises an elongated, substantially cylindrical, housing (1), a plurality of capillaries (2), which are fastened inside the housing (1) by means of partitions (5) so that they are substantially parallel with the longitudinal axis of the housing (1) and mutually placed in defined distances from, while the housing (1) contains an inlet (4a) and an outlet (4b) of the cooling/heating liquid and a finishing element (9) at each end, the element containing an input (12a), or output (12b) of the cooled/heated liquid characterised in that it comprises inside the housing (1) at least one laminarizer (6) in the form of a partition with a plurality of openings (10), always one opening (10) for each capillary (2), the diameter of the opening (10) being bigger than the outer diameter of the capillary (2), and laminarizer (6) is placed so that capillaries (2) go through the centre of the opening (10) in the laminarizer (6). Preferably, the heat exchanger according to the invention comprises two laminarizers (6). The heat exchanger according to the invention is preferably made whole of plastics. Preferably, the exchanger according to the invention is further provided with a temperature sensor at the input (12a) and/or output (12b) of the cooled/heated liquid.
