Background technology
General heat exchanger all has refrigerant and two heat exchanger channels of heating agent at present, and the cross-sectional area of these two heat exchanger channels all equates, the identical heat exchanger channels in this middle section is at processing and fabricating and installed multiple benefit, the medium that at the same time, interior two heat exchanger channels pass through is identical volume substantially, is convenient to control.But in the inconsistent situation of the specific heat capacity of coolant media and thermal medium, the heat that the cold and hot medium of equal volume carries is inconsistent, and adopts the identical heat exchanger channels in cross section to tend to produce refrigerant and the inadequate situation appearance of heating agent heat exchange.
Summary of the invention
The inadequate defective of heat exchange easily occurs in order to make up above-mentioned refrigerant heating agent in the inconsistent situation of specific heat capacity, the utility model proposes a kind of plate type heat exchanger with various heat exchange channel cross-section with different cross-sectional.
The technical scheme that realizes above-mentioned beneficial effect is, a kind of plate type heat exchanger with various heat exchange channel cross-section, comprise casing, be fixed on heat exchanger plates bundle and the wide medium import and export that is connected with the heat exchanger plates bundle and narrow medium import and export in casing, described heat exchanger plates bundle comprises a plurality of heat exchanger plates, a plurality of heat exchanger plates are fixed together and form wide heat exchanger channels and narrow heat exchanger channels, and wide heat exchanger channels two ends are connected with wide medium import and export, and narrow medium channel two ends are connected with narrow medium import and export.In the technical program, heat exchanger channels comprises two kinds of heat exchanger channels of width, and the rank street area of two heat exchanger channels is inconsistent, select respectively wide or narrow heat exchanger channels to pass into heat transferring medium according to the size of Media Ratio thermal capacitance when the Media Ratio thermal capacitance at heat exchanger two ends is inconsistent, the heat that guarantees heat transferring medium carries out full and uniform exchange, improves efficiency of heat exchanger.
On described heat exchanger plates respectively punching press have raised corrugations and the depression ripple, the cross-sectional area of raised corrugations greater than the depression ripple the rank street area.In the technical program, heat exchanger plates is convenient to production easy to process by the impact style moulding.
Described casing comprises left box body and right case, and wide medium inlet and narrow media outlet and left box body are secured together, and wide media outlet and narrow medium inlet and right case are secured together, and are communicated to together by connecting box between left and right casing.In the technical program, the mode that adopts casing to connect can increase or reduce casing according to actual needs, has completed the use of heat exchanger, and is convenient, flexible.
Between wide medium inlet and heat exchanger plates bundle, be connected with respectively the dielectric distribution device between narrow medium inlet and heat exchanger plates bundle.In the technical program, adopt the dielectric distribution device to guarantee medium being evenly distributed after entering heat exchanger, make the heat exchanger channels that enters of its uniform and stable, improved utilization ratio.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of a kind of embodiment of the present utility model;
Fig. 2 is the structural representation of a kind of embodiment of heat exchanger plates of the present utility model;
In figure, 1, casing; 11, left box body; 12, right case; 13, connecting box; 2, heat exchanger plates bundle; 3, heat exchanger plates; 4, heat exchanger channels; 41, wide medium import; 42, wide media outlet; 5, narrow heat exchanger channels; 51, narrow medium import; 52, narrow media outlet; 6, dielectric distribution device.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
In conjunction with Fig. 1, a kind of plate type heat exchanger with various heat exchange channel cross-section, comprise casing 1, be fixed on the interior heat exchanger plates bundle 2 of casing and the wide medium import 41 that is connected with the heat exchanger plates bundle, wide media outlet 42 and narrow medium import 51, narrow media outlet 52, described heat exchanger plates bundle comprises a plurality of heat exchanger plates 3, a plurality of heat exchanger plates are fixed together and form wide heat exchanger channels 4 and narrow heat exchanger channels 5, wide heat exchanger channels two ends are connected with wide medium import and export, and narrow medium channel two ends are connected with narrow medium import and export.In the present embodiment, on described heat exchanger plates respectively punching press raised corrugations 31 and depression ripple 32 are arranged, the cross-sectional area of raised corrugations is greater than the rank street area of depression ripple.Described casing comprises left box body 11 and right case 12, and wide medium inlet and narrow media outlet and left box body are secured together, and wide media outlet and narrow medium inlet and right case are secured together, and are communicated to together by connecting box 13 between left and right casing.Between wide medium inlet and heat exchanger plates bundle, be connected with respectively dielectric distribution device 6 between narrow medium inlet and heat exchanger plates bundle.
For general full-welding plate-type heat exchanger, the medium entrance sleeve is generally less, and a plurality of plates form plate area of beam is very large, if medium directly enters the heat exchange cross section of plate bundle, medium can produce the skewness phenomenon, the flow of nearly adapter passage is large, and the flow of far taking over runner is little, affects heat exchange efficiency.The utility model has increased the dielectric distribution device in the import of media of both sides, has realized that medium flows each interchannel is uniform, directly flow through in having avoided again taking over come the erosion corrosion that causes of medium frontal impact plate.The profile that it should be noted that the dielectric distribution device is decided by medium import cross section.The material of distributor and thickness are pressed medium physical property and media operation pressure and operating temperature and are decided, and pressure is large, the high distributor of temperature thickness is thick.
This patent product can easily can be realized according to the size of heat exchange area one, two or several tandem compounds, no matter being several, heat exchanger is used in combination, fat pipe flow process number average is single process, and narrow passage flow process number is consistent with the number of units of combination, and namely several are combined as several flow processs.
The above; be general case study on implementation of the present utility model; be not that the utility model is imposed any restrictions; every any simple modification, change and equivalent structure of above embodiment being done according to the utility model technical spirit changes, and all still belongs in the protection domain of technical solutions of the utility model.
