Abstract
The utility model relates to a double wall plate type heat exchanger in which heat exchange media do not directly and mutually contact. The utility model is formed by the assembly of heat exchange plates with double wall plates, gland bushes between the plates and a framework, wherein, the pore diameters of two plate sheet angle pores of the heat exchange plates with double wall plates are respectively large and small, and the overlapped part of the large and the small pores is in the sealing range of the gland bushes of the angle pores. The utility model has the advantages of simple structure, no weld, easy fabrication, reliable work, time and labor saving, low fabrication cost, and convenient, flexible and fast plate sheet wash and replacement.
Description
The utility model relates to a kind of double-walled plate heat exchange unit that heat exchange medium does not directly contact in the device.
Definitely prevent the heat exchange occasion that two media mixes at need, adopt the double-walled sheet heat exchanger more.It mainly is made of the sealing gasket between double-walled plate heat exchanger plates, plate and several most of assemblings of framework.The pore size unanimity in the hole, two plate angles of double-walled plate heat exchanger plates in the present double-walled sheet heat exchanger, in order to prevent that fluid from spilling between the plate aperture of double-walled plate runner, need the aperture of two plates is welded together, forms sealing ring, promptly with the sealing between welding realization plate aperture, the seal washer at place, hole, angle only is used for the sealing between the heat exchanger plates.The deficiencies in the prior art part mainly is: guarantee sealing between the plate aperture by welding, and complex structure, specification requirement height, not only time-consuming, and be unfavorable for cleaning replacing with plate.
The purpose of this utility model is to avoid weak point of the prior art, and a kind of simple structure is provided, and has not only saved time to save trouble, but also be beneficial to and clean and double-walled plate plate type heat exchanger product that plate is changed.
Can take following technical scheme to realize purpose.Double-walled plate plate type heat exchanger, still constitute by the sealing gasket between double-walled plate heat exchanger plates, plate and several most of assemblings of framework, but small one and large one is made in the aperture in hole, two plate angles of double-walled plate heat exchanger plates, and the overlapping position of macropore and aperture is within the sealing range of hole, angle seal washer.Make unjointed double-walled plate plate type heat exchanger product.Angle Kong Chu
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
Fig. 1 is the front view of a kind of structure of double-walled plate heat exchanger plates in the double-walled plate plate type heat exchanger;
Fig. 2 is the K--K cutaway view of a kind of structure of Fig. 1;
Fig. 3 is the K--K cutaway view of the another kind of structure of Fig. 1.
This double-walled plate plate type heat exchanger, only one in the aperture in hole, two plate angles of double-walled plate heat exchanger plates big one little, and the position that is overlapping of macropore and aperture is within the sealing range of hole, angle seal washer, be that macropore and the aperture sealing position between the sheet group overlaps, so just can make the seal washer at hole, two plate group angles place not only be used for sealing, simultaneously but also be used for sealing between the plate of heat exchanger plates between the heat exchanger plates, kill two birds with one stone.Big, which plate of which plate of aperture in hole, two plate angles of double-walled plate heat exchanger plates little to not influence of serviceability, promptly has same effect.Concrete structure as for other position of other member or member in the double-walled plate plate type heat exchanger, as the sealing gasket between double-walled plate heat exchanger plates, plate and the shape of framework, size etc. can be same as the prior art, also can adopt other version, be that they all can be taken the circumstances into consideration to set according to using needs.
Double-walled plate heat exchanger plates in the plate type heat exchanger of double-walled plate shown in the accompanying drawing 2 example is that the aperture in upper sheet space (1) hole, angle is big, the aperture in lower sheet space (2) hole, angle is little, and the overlapping position of macropore and aperture is in the structure within the sealing range of hole, angle seal washer.
Double-walled plate heat exchanger plates in the plate type heat exchanger of double-walled plate shown in the accompanying drawing 3 example is that aperture little, lower sheet space (2) hole, angle, the aperture in upper sheet space (1) hole, angle is big, and the overlapping position of macropore and aperture is in the structure within the sealing range of hole, angle seal washer.
The result of use of these two kinds of embodiment is all preferable, does not have difference on the performance.
The relative prior art of the technical program has following advantage and effect:
Simple structure need not welding, makes easily reliable operation; Saving of work and time falls Low manufacturing expense; It is convenient, flexible to clean and change plate, quick.
Claims (3)
1, a kind of double-walled plate plate type heat exchanger, constitute by sealing gasket between double-walled plate heat exchanger plates, plate and framework assembling, it is characterized in that: the aperture in hole, two plate angles of double-walled plate heat exchanger plates small one and large one, and the overlapping position of macropore and aperture is within the sealing range of hole, angle seal washer.
2, double-walled plate plate type heat exchanger as claimed in claim 1, it is characterized in that: double-walled plate heat exchanger plates is that the aperture in upper sheet space (1) hole, angle is big, the aperture in lower sheet space (2) hole, angle is little, and the overlapping position of macropore and aperture is in the structure within the sealing range of hole, angle seal washer.
3, double-walled plate plate type heat exchanger as claimed in claim 1, it is characterized in that: double-walled plate heat exchanger plates is that the aperture in upper sheet space (1) hole, angle is little, the aperture in lower sheet space (2) hole, angle is big, and the overlapping position of macropore and aperture is in the structure within the sealing range of hole, angle seal washer.
