Abstract
The utility model relates to the main heat exchanger that a kind of plate bundle local thickeies, and comprises thickening plate; Described thickening plate is arranged on the surrounding outermost of plate bundle, and the inner side of thickening plate is also provided with process layer; Described thickening plate decreases more than two layers process layers in end socket welding under constant, still can reach the effect identical with existing structure, thus reduces the main cost changed.The utility model alleviates master and changes weight, reduces production cost.
Description
Technical field
The utility model relates to plate fin type heat exchanger apparatus field in cryogenic air separation equipment, refers in particular to one and alleviates and main change weight, the main heat exchanger that a kind of plate bundle local reducing production cost thickeies.
Background technology
In existing plate-fin heat exchanger, the each passage of plate bundle body mixes suitable end socket, form a complete heat exchanger, the head thickness of each passage is determined by the design pressure of each passage, the design pressure of hot fluid is high compared with the design pressure of cold fluid under normal circumstances, therefore the thickness of the end socket of hot fluid is also comparatively thick, in high pressure heat exchanger, the pressure of hot fluid can reach about 6.0MPa especially, the thickness of such end socket can reach more than 30mm, ensure end socket and the welding of plate bundle body, normally adopted more than three layers process layers in the past, as shown in Figure 1, to ensure the welding distance of end socket, because this increasing the weight of heat exchanger, also the heat exchanger cost increased, for this reason, we have developed one and alleviate and main change weight, the main heat exchanger that a kind of plate bundle local reducing production cost thickeies.
Utility model content
The utility model object provides one to alleviate main to change weight, the main heat exchanger that a kind of plate bundle local reducing production cost thickeies to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: the main heat exchanger that a kind of plate bundle local thickeies, and comprises thickening plate; Described thickening plate is arranged on the surrounding outermost of plate bundle, and the inner side of thickening plate is also provided with process layer.
Preferably, the length of described thickening plate is greater than the width 50mm of end socket, and the width of thickening plate is 200mm, and the thickness of thickening plate is that head thickness deducts 21mm, and the material of described thickening plate is aluminium sheet.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The main heat exchanger that plate bundle local described in the utility model thickeies is provided with thickening plate by plate Shu Sizhou, decreases the processing number of times of process layer, thus reduces main weight of changing, and reduces production cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the main heat exchanger described in prior art;
Accompanying drawing 2 is the general structure schematic diagram of the main heat exchanger that plate bundle described in the utility model local thickeies;
Wherein: 1, process layer; 2, low-pressure channel; 3, high-pressure channel; 4, thickening plate; 5, plate bundle.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 2 is the main heat exchanger that plate bundle described in the utility model local thickeies, and comprises thickening plate 4; Described thickening plate 4 is arranged on the surrounding outermost of plate bundle 5, and the inner side of thickening plate 4 is also provided with process layer; The length of described thickening plate 4 is greater than the width 50mm of end socket, and the width of thickening plate 4 is 200mm, and the thickness of thickening plate 4 is that head thickness deducts 21mm, and the material of described thickening plate 4 is aluminium sheet.
In use: described thickening plate 4 decreases more than two layers process layers in end socket welding under constant, still can reach the effect identical with existing structure, thus reduces the cost led and change.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The main heat exchanger that plate bundle local described in the utility model thickeies is provided with thickening plate by plate Shu Sizhou, decreases the processing number of times of process layer, thus reduces main weight of changing, and reduces production cost.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
