Abstract
This utility model discloses a end plate new structure of plate type heat exchanger. Upper end plate and down plate are arranged at the said structure's top end and bottom end separately. Upper end plate which located at the Basal portion of upper inlet and outlet is arranged a upper annular shoulder on which set a pad, the thickness of pad is larger than the depth of upper annular shoulder, and the opening of topmost heat exchange fin is sealed; Down end plate which located at the Basal portion of down inlet and outlet is arranged a down annular shoulder on which set a pad, the thickness of pad is larger than the depth of down annular shoulder, and the opening of downmost heat exchange fin is sealed. Hence, heat exchange water will not flow through the space between the upper end plate and the topmost heat exchange fin and the space between the down end plate and the downmost heat exchange fin, and it's impossibe for the end plate being corroded ,therefore, end plate may be made of ordinary material so as to save raw material, reduce production costs.
Description
Technical field
The utility model relates to a kind of end plate new structure of plate type heat exchanger, especially relates to a kind of improvement to tip plate configurations.
Background technology
In the prior art, plate type heat exchanger up and down end plate and therebetween the heat exchanger fin group at two ends is the same material making.But in actual the use, heat exchange water just circulates between end plate and heat exchanger fin group heat exchanger fin up and down, prevent that just heat exchange water just is designed to end plate the material the same with the heat exchanger fin group to the corrosion of end plate, seldom play the effect of heat exchange, and the material cost valency of heat exchanger fin is higher, so just waste raw material, increased manufacturing cost.
Summary of the invention
In order to solve above-mentioned existing problem of the prior art, the utility model provides a kind of end plate new structure of plate type heat exchanger.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of end plate new structure of plate type heat exchanger, comprise upper head plate and bottom plate, be provided with the heat exchanger fin group that some plate-type heat-exchange sheets constitute up and down between the end plate, described upper head plate is provided with water inlet and upper water-out mouth, and respectively is provided with annular shoulder on the upper head plate of last water inlet and upper water-out mouth base portion; Described bottom plate is provided with down water inlet and lower outlet, and respectively is provided with a following annular shoulder on the bottom plate of following water inlet and lower outlet base portion; The described annular shoulder of going up projects upwards, and described annular shoulder down is outstanding downwards, and is provided with Upper gasket in last annular shoulder, is being provided with lower gasket in the annular shoulder down.
The thickness of described Upper gasket and lower gasket is slightly larger than the degree of depth in annular shoulder and the following annular shoulder respectively.Described Upper gasket and heat exchanger fin group be the opening phase configuration of a slice heat exchanger fin topmost; The opening phase configuration of the bottom a slice heat exchanger fin of described lower gasket and heat exchanger fin group.By Upper gasket the opening of upper head plate with heat exchanger fin group the top a slice heat exchanger fin sealed mutually, the opening of bottom plate with the bottom a slice heat exchanger fin of heat exchanger fin group sealed mutually by lower gasket.
Adopt technique scheme, in upper head plate and heat exchanger fin group topmost between a slice heat exchanger fin, all isolated by gasket seal between bottom plate and the heat exchanger fin group bottom a slice heat exchanger fin, heat exchange water therebetween no longer circulates, therefore upper head plate and bottom plate can adopt the common material manufacturing, to save material, reduce production costs.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model plate type heat exchanger;
Accompanying drawing 2 is cross section structure schematic diagrames of the utility model A-A and B-B.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1 and Fig. 2, the utility model be on heat exchanger fin group 3 and below be respectively equipped with upper head plate 1 and bottom plate 2, and be provided with water inlet 5 and upper water-out mouth 7 in the side on the upper head plate 1, opposite side on the upper head plate 1 is provided with the import 4 and the outlet 6 of cold-producing medium, side on bottom plate 2 be provided with down water inlet 5 ' and lower outlet 7 ', the opposite side on the bottom plate 2 be provided with the import 4 of cold-producing medium ' and outlet 6 '.
The upper head plate 1 of wherein going up water inlet 5 and upper water-out mouth 7 base portions is provided with annular shoulder 11, in last annular shoulder 11, be provided with pad 13, the thickness of pad 13 is slightly larger than the degree of depth of annular shoulder 11, and with the opening sealing of the top a slice heat exchanger fin 31 of heat exchanger fin group 3;
Following water inlet 5 ' and the bottom plate 2 of lower outlet 7 ' base portion be provided with down annular shoulder 21, be provided with pad 23 in the annular shoulder 21 down, the thickness of pad 23 is slightly larger than down the degree of depth of annular shoulder 21, and with the opening sealing of bottom a slice heat exchanger fin 32 of heat exchanger fin group 3.
Like this, at the heat exchange water that all no longer circulates between upper head plate and the heat exchanger fin group the top a slice heat exchanger fin, between bottom plate and the bottom a slice heat exchanger fin of heat exchanger fin group, with regard to the possibility that does not exist end plate to be corroded, therefore end plate can adopt the common material manufacturing, to save material, reduce production costs.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
