Abstract
The utility model discloses a plate type heat exchanger, including the body, set up slab in the body in the middle of, set up at hot -fluid inlet tube, the cold flow body drain pipe on body upper portion and set up cold flow body inlet tube and the hot -fluid drain pipe in the body lower part, setting valve pipeline on the cold flow body drain pipe, manually -operated valve pass through the valve pipeline and arrange water piping connection with the cold flow body, the stack of slab from the top down is in the same place, and lower floor's slab is mirror symmetry with adjacent upper slab, leaves the interval between the adjacent slab, the surface of every slab sets up convex part and recess, forms heat transfer media channel and water passageway between the adjacent slab. The beneficial effects of the utility model are that, set up the structure into mirror symmetry through setting up convex part and recess and adjacent slab with every slab surface, can improve heat exchange efficiency, simultaneously, through setting up manual valve, effectively avoided the machine damage of the heat exchanger that abnormal conditions result in to appear.
Description
Technical field
The utility model relates to field of heat exchangers, especially a kind of plate type heat exchanger.
Background technology
At present, plate-type heat exchanger slab common structure is herringbone wave, and this structure Problems existing is fluid Contact limited area, and heat exchange efficiency is not high, simultaneously, when running into abnormal conditions in use procedure, heat exchanger possibly cannot obtain water pump conveying water, in the maintenance period, water water temperature after heat exchanger raises rapidly, heat exchanger inside is in high-temperature high-pressure state, very easily causes the damage of machine, affects service life.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of plate type heat exchanger.
For achieving the above object, the utility model adopts following technical proposals:
A kind of plate type heat exchanger, comprises body, is arranged at the middle plate of body, the hot fluid water inlet pipe being arranged on body upper part, cold fluid drainpipe and is arranged on cold fluid water inlet pipe and the hot fluid drainpipe of body lower part; Cold fluid drainpipe arranges valve pipe, and manually-operated gate is connected with cold fluid drainpipe by valve pipe.
Plate is superimposed together from top to bottom, and lower floor's plate and adjacent upper plate are specular, leave spacing between adjacent plate; The surface of each plate is recessed, bottom surface evagination and form multiple protuberance and groove respectively, heat exchanging medium passage is formed between the surface of a plate and the bottom surface of adjacent front plate, aquaporin is formed between the bottom surface of this plate and adjacent rear sheet surface, heat exchanging medium passage and aquaporin all arrange multiple, and multiple heat exchanging medium passage and aquaporin are arranged alternately; The both sides of adjacent plate arrange heat-preservation cotton, and the surface periphery of each plate arranges sealing gasket, and sealing gasket is located between adjacent plate, form sealing and abut.
The beneficial effects of the utility model are, be set to mirror image by each sheet surface is arranged protuberance and groove and adjacent plate, can heat exchange efficiency be improved, simultaneously, by arranging hand-operated valve, effectively prevent the damage that the heat exchanger that abnormal conditions cause appears in machine.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is plate schematic cross-section;
Wherein 1. bodies, 2. plate, 3. hot fluid water inlet pipe, 4. cold fluid drainpipe, 5. valve pipe, 6. hand-operated valve, 7. cold fluid water inlet pipe, 8. hot fluid drainpipe, 9. heat-preservation cotton, 10. sealing gasket, 11. protuberances, 12. grooves, 13. heat exchanging medium passages, 14. aquaporins.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of plate type heat exchanger, comprises body 1, is arranged at the middle plate 2 of body 1, the hot fluid water inlet pipe 3 being arranged on body 1 top, cold fluid drainpipe 4 and is arranged on cold fluid water inlet pipe 7 and the hot fluid drainpipe 8 of body 1 bottom; Cold fluid drainpipe 4 is arranged valve pipe 5, manually-operated gate 6 is connected with cold fluid drainpipe 4 by valve pipe 5.
As shown in Figure 2, plate is superimposed together from top to bottom, and lower floor's plate and adjacent upper plate are specular, leave spacing between adjacent plate; The surface of each plate is recessed, bottom surface evagination and form multiple protuberance 11 and groove 12 respectively, heat exchanging medium passage 13 is formed between the surface of a plate and the bottom surface of adjacent front plate, aquaporin 14 is formed between the bottom surface of this plate and adjacent rear sheet surface, heat exchanging medium passage 13 and aquaporin 14 all arrange multiple, and multiple heat exchanging medium passage and aquaporin are arranged alternately; The both sides of adjacent plate arrange heat-preservation cotton 9, and the surface periphery of each plate arranges sealing gasket 10, and sealing gasket 10 is located between adjacent plate, form sealing and abut.
The course of work is as follows:
Heat transferring medium enters plate 2 from hot fluid water inlet pipe 3, flow into heat exchanging medium passage 13, water enters plate 2 from cold fluid water inlet pipe 7, flow into aquaporin 14, water is flowing through in aquaporin 14 process, heat is delivered in water by plate by heat transferring medium, water absorbs thermal temperature and raises, owing to becoming specular between plate, compared with designing with existing herringbone wave, within the unit interval heat transferring medium in heat exchanging medium passage specific heat capacity higher than the specific heat capacity of heat transferring medium between herringbone wave plate, improve heat exchange heat, improve heat transfer efficiency, enhance heat transfer effect,
When running into abnormal conditions in the heat exchanger course of work, heat exchanger internal temperature rises fast, forms vapor injection, open hand-operated valve 6, steam is discharged along valve pipe 5, avoids occurring that heat exchanger inside is in high-temperature high-pressure state, and causes the situation of the damage of machine.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
