Abstract
The utility model relates to a corrugated plate of a plate-type heat exchanger. A continuous row of W-shaped corrugated bodies are punched in a thin stainless steel plate and in the shape of waves in the horizontal direction and a direction perpendicular to a plate face. The trend of each corrugated body is W-shaped corrugated. Wave crests and wave troughs of all corrugated bodies share the same direction. Compactly arranged W-shaped corrugated bodies and cross sections of corrugated body gaps between W-shaped corrugated bodies form continuous wave shapes. Each W-shaped corrugated body is provided with a first wave crest, a wave trough and a second wave crest from left to right. An included inner angle becomes gradually larger level by level. The width of a corrugated body gap between two corrugated bodies becomes gradually larger from left to right. As the inner angles of corrugated bodies between two corrugated plates and gaps between corrugated bodies change, corrugated plates are overlapped in reversed mode and form fluid channels by being brazed. And the cross sections of the fluid channels are arranged from small to large and correspondingly, the fluid channel changes from small to large or otherwise. Thus, the fluid channels are in line with the rule that cool fluid gets larger after absorbing heat and hot fluid gets smaller after losing heat so that heat transmission rate of the fluid does not reduce. The above characteristic is the key to improve efficiency of heat transmission in the corrugated plate of the plate-type heat exchanger.
Description
Technical field
The utility model relates to the heat-exchange apparatus field, specifically refers to a kind of corrugated plating of plate type heat exchanger.
Background technology
Plate type heat exchanger is usually used in the engineerings such as heating, condensation and UTILIZATION OF VESIDUAL HEAT IN of material in industrial production.Its function is the heat transferred one other fluid with a kind of fluid.Therefore the efficient of transmitting in order to improve heat makes every effort to accomplish that two kinds of fluids are across heat exchanger plates heat-shift fully, so whether most important the structure of heat exchanger plates is rationally.The corrugated plating of present most of plate type heat exchanger, its bellows-shaped is " people " font, namely stamp out continuously arranged " people " font ripple (seeing Fig. 2) at a stainless sheet steel, then two ripple lags are oppositely superimposed up and down, with copper brazing technique all contact points are welded again, form some not connected fluid passages.In different passages, lead to people's cold fluid and hot fluid when installing and using, thereby realize the purpose of exchange heat.But through carefully analyzing, the corrugated plating of this " people " font is after oppositely superimposed, herringbone is cross-contact up and down, but the wall scroll ripple contact point in two heat exchanger plates only has 2 points up and down, so the passage number of separating after soldering is not a lot, that is to say that the area of two kinds of flow baffle heat exchange in unit are is limited.Therefore want to segment passage at plate face of the same area, make every effort to realize the maximization of fluid heat transfer area, improve with regard to decorative pattern shape, the structure that must exchange hot plate.
The utility model content
The purpose of this utility model is; Heat exchanger plates decorative pattern to existing plate type heat exchanger improves, and increases up and down two heat exchanger plates contact solder joint as far as possible, and number of channels is increased, and in the same traffic situation fluid is segmented, thereby improves heat exchange efficiency.
The scheme of the utility model technical solution problem is: a kind of corrugated plating of plate type heat exchanger, to stamp out continuously arranged some W shape corrugated bodies at a stainless sheet steel, the horizontal direction of described W shape corrugated body and with the equal undulate of plate face vertical direction: namely every corrugated body trend is W shape waveform, and the crest of described all corrugated bodies is consistent with the trough direction; Some compact arranged W shape corrugated bodies and between the corrugated body clearance cross section consist of continuous waveform.
The interior angle that described every W shape corrugated body has the first trough, crest and the second trough, described the first trough, crest and the second trough from left to right becomes large step by step.
The corrugated body gap width gradually changes from left to right from narrow to wide between the described adjacent corrugations body.
What the corrugated plating of above-mentioned design was useful is, owing to the crack of asking between two corrugated plating ripple interior angles and the corrugated body changes, also therefore form from small to large arrangement in reverse superimposed cross section by soldering formation fluid passage, the fluid passage is from small to large corresponding or variation from big to small also.Make volume increase hot fluid because losing the Changing Pattern of heat volume-diminished so the fluid passage that forms meets cold fluid because obtaining heat, the speed that the fluid heat conducts can not decayed, the key of Here it is the utility model raising heat exchange efficiency.

Fig. 2 is former herringbone corrugated plating floor map;
Fig. 3 is the schematic diagram of adjacent corrugations body cross section;
Each title and numbering among the figure: 1-corrugated body, 2-the first trough, 3-crest, 4-the second trough, 5-corrugated body gap.
The specific embodiment
As shown in figures 1 and 3, a kind of corrugated plating of plate type heat exchanger, to stamp out continuously arranged W shape ripple at a stainless sheet steel, described W shape ripple is at plate face level and the equal undulate of the both direction vertical with the plate face: namely every ripple itself is W shape waveform, and the corrugated body cross section of some arrangements forms continuous waveform.Described every W shape ripple has two troughs and crest, the trough of described every ripple and the interior angle of crest change from small to large, and namely the interior angle of the first trough interior angle, crest interior angle, the second trough becomes large step by step from left to right.The crest of described adjacent two ripples is put to consistent with trough, and the trough width that forms between the described adjacent corrugations body changes from left to right from narrow to wide.Because the variation of two corrugated plating ripples, in the oppositely superimposed also from small to large arrangement of cross section that forms the fluid passage by soldering, so meeting cold fluid, the fluid passage that forms make volume increase hot fluid lose the Changing Pattern that heat makes volume-diminished because obtaining heat, the fluid passage is from small to large corresponding or Changing Pattern from big to small also, the speed of fluid heat conduction can not decayed, the key of Here it is the utility model improves heat exchange efficiency.
W shape corrugated plating has been compared very large difference with former herringbone corrugated plating: at first be that contact point increases, thereby the port number of fluid is increased greatly, reach the heat exchange area when segmenting river rising in Ningxia and flowing into central Shaanxi stream in the same traffic situation, increasing two kinds of cold fluid and hot fluids, make heat exchange abundant; To be that channel cross-section is ascending or descending gradually change for next, meet the rule that fluid expands with heat and contract with cold, make fluid be close to all the time vias inner walls and flow, the speed of fluid heat conduction can not decay, and experimental results show that the utility model product is significant to improving heat exchange efficiency.
