Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As depicted in figs. 1 and 2, the full welded plate heat exchangers of the utility model, comprise by two piece of first clamping plate 6, the housing that two piece of second clamping plate 7 and two end sockets 1 are formed, plate bundle 2 is provided with in this housing, the plate 8 of the rectangle that plate bundle 2 is vertically arranged by polylith forms, passage is formed between adjacent plate 8, top and the bottom of all plates 8 are welded with closure plate 4 respectively, plate bundle 2 is welded with dividing plate 3 respectively towards the two ends of end socket 1, dividing plate 3 is comb teeth-shaped towards one end of plate bundle 2, adjacent two boards sheet 8 to snap on dividing plate 3 between adjacent two comb, the profile of dividing plate 3 and the inner wall section shape of end socket 1 suitable, dividing plate 3 welds with plate bundle 2 and end socket 1 respectively, the cavity that end socket 1 and plate bundle 2 surround is divided into two not connected cavitys by dividing plate 3.The part that same passage is positioned at above a dividing plate 3 is open-minded, what then this passage was positioned at below this dividing plate 3 is partially enclosed, so, it is partially enclosed that this passage is positioned at above another dividing plate 3, the part that this passage is positioned at below another dividing plate 3 is open-minded, and the opening of the passage adjacent with this passage, the opening of closed state and this passage, closed state are contrary.The cavity connects opened above end and a dividing plate 3 of a passage, then another of this passage opens the cavity connects below end and another dividing plate 3; Otherwise the cavity connects opened below end and a dividing plate 3 of a passage, then another of this passage opens the cavity connects above end and another dividing plate 3.
For strengthening heat transfer and improving bearing capacity, plate 8 surface can be pressed into the ripple of various shape according to heat transfer requirement, or arranges spacing column or fin between adjacent plate 8.
The sealed end of passage be adjacent two plates 8 through roll-welding side two long weld seams 5 or be welded with sealing strip.
Seal form all in the utility model heat exchanger is welded seal.
In the full welded plate heat exchangers of the utility model, adjacent two passages are not connected cold journey and hot journey, and the complete adverse current of cold and hot fluid flows to.The cold fluid and hot fluid that dividing plate 3 makes to enter in cavity that end socket 1 and plate bundle 2 surround flows respectively in respective passage, carries out heat exchange.As: thermal medium enters the manifold of heat exchanger lower left quarter from lower left quarter import, and as shown in Figure 3, thermal medium enters the openend of the passage be communicated with this manifold, and this passage is called A channel, and the passage adjacent with A channel is called channel B; Thermal medium flows from left to right in A channel, and the A channel of right lower quadrant is obstructed, and channel B is opening; The A channel of upper right quarter manifold is opening, and channel B is obstructed, and the channel B of upper left quarter manifold is opening, and A channel is obstructed, so thermal medium enters into the manifold of upper right quarter from A channel, is finally arranged outward by the thermal medium outlet of upper right quarter; Equally, cold medium enters the manifold of right lower quadrant from the import of heat exchanger right lower quadrant, the channel B of right lower quadrant is opening, and A channel is obstructed, cold medium is right-to-left flowing in channel B, the channel B of lower left quarter is obstructed, A road is opening, and the channel B of upper left quarter manifold is opening, A channel is obstructed, and the A channel of upper right quarter manifold is opening, and channel B is obstructed, so cold medium enters into the manifold of upper left quarter from channel B, finally arranged outward by the cold media outlet of upper left quarter.
The utility model also can realize multi-pass configuration, be four flowage structures wherein, and the structural principle of each flow process is identical with above-mentioned single-pass configuration shown in Fig. 4 and Fig. 5.In plate bundle 2 one end towards end socket 1, weld four pieces of dividing plates 3 successively from top to bottom, the cavity that end socket 1 and plate bundle 2 surround is divided into five not connected cavitys by these four pieces of dividing plates 3, demarcation strip has been horizontally disposed with between adjacent two pieces of dividing plates 3, plate bundle 2 is divided into four not connected parts by these three pieces of demarcation strips, adjacent two parts are communicated with by the cavity between adjacent two dividing plates 3, after making the medium entered in end socket 1 flow through four flow processs, flow out from heat exchanger, the two media flow regime entering this multi-pass configuration heat exchanger is still consistent, remain the complete adverse current of high heat transfer efficiency, and two media realizes many journeys simultaneously.
The utility model heat exchanger, rational in infrastructure, channel design is unique, can realize countercurrent flow completely, heat transfer efficiency is high, and plate bundle load performance is good, can be applicable to the general operating mode such as food, chemical industry, oil, metallurgy, electric power, manufacturing processing technic is simple, is applicable to batch production and promotes the use of.
