Embodiment Construction

[0030] figure 2A first embodiment of the evaporator according to the invention is shown, here the evaporator is divided into a total of three collecting tanks 4 , 5 , 6 for the refrigerant. The division of the flow channel 1 into separate header boxes 4, 5, 6 is achieved by a special plate 7, wherein at least one of the openings 1a and 1b is replaced by a baffle 7a. The baffle 7a can prevent all refrigerant from flowing through the vertical inlet and outlet. Since the baffle plate 7 is vertically offset, a reverse direction 8 is formed at the end of the first header box and the end of the second header box, so the refrigerant first flows from the inlet parallel to the length direction in the first header box 1a flows to the outlet 1b side, then turns 180 degrees, then flows through the evaporator in the second header parallel to the length direction in the opposite direction to the first header, and then reverses again, in the third header The tank flows through the evapora...

Abstract

The invention provides an evaporator used for a motor vehicle, comprising a plurality of plates, runners of the first kind and runners of the second kind, wherein the plates are stacked in parallel in the vertical direction and are provided with openings which are aligned with each other and are used for the supply and the backflow of first fluid and second fluid; the first fluid is refrigerating fluid; the runners of the first kind are shaped between the two adjacent plates and are used for conveying the first fluid; the runners of the second kind are alternately arranged and are used for conveying the second fluid; the heat exchange areas of the plates have the length of the refrigerating fluid flowing direction and the width being vertical to the refrigerating fluid flowing direction, wherein the ratio of the length to the width is 1.3; the refrigerating fluid flows past the first flow collection boxes of one or more runners of the first kind, and the refrigerating fluid reversely flows past the second flow collection boxes of one or more runners of the first kind after flowing past the first flow collection boxes.

Description

technical field [0001] The present invention generally relates to an evaporator, in particular an evaporator for a motor vehicle. The invention also relates to a device for cooling a heat source in a motor vehicle. Background technique [0002] DE102004036951A1, corresponding U.S. Patent Application Publication No. 20070107890, the entire content of which is referenced in this application, it is proposed to use a heat exchanger composed of a plurality of parallel plates connected together, this design is also known as laminated plate Heat exchanger as evaporator of the cooling circuit of a motor vehicle. In this design, heat can be absorbed from the coolant flowing through the heat exchanger during the evaporation of the refrigerant. [0003] In existing heat exchangers used as evaporators, it is necessary to make the length of the plate element long enough in the refrigerant flow direction to ensure sufficient evaporation, in particular, to ensure sufficient superheating ...
