Description
Technical field
The utility model relates to a kind of vaporising device for quick freezing and defrosting in refrigeration industry, and especially a kind of multichannel evaporation is dull and stereotyped.
Background technology
The evaporation flat board of refrigeration industry is the common heat-exchanging part (genus evaporimeter) of a kind of routine, common evaporation plate work principle is that refrigerant liquid enters in evaporation flat board after reducing pressure by regulating flow, ebullition, gasification becomes steam, absorb the heat of scars on evaporation planar surface, realize the object that scars cool.By multi-disc evaporate flat board from bottom to top hierarchal arrangement just constitute plate freezer.
The evaporation of applying in the market is dull and stereotyped, its internal structure is mainly veneer single channels structure (as shown in Figure 1), it mainly through in the heat-conducting planar that is spliced at polylith hollow heat conduction flat board 1 by dividing plate 2 and be arranged at the dull and stereotyped two ends of every block hollow heat conduction and form the transmission channel of a unique continuous print serpentine pathway 301 as cold-producing medium by arranging block 10 in feed flow end end socket 401 and air return end end socket 501 in the inside of heat-conducting planar, the initiating terminal of serpentine pathway 301 is connected with refrigerant feed liquid end by bend pipe flange 8.Owing to being veneer single channels version, cold-producing medium must be made to need to flow through the path in hollow heat conduction flat board 1 successively, thus cause cold-producing medium circulation flow path line length in evaporation is dull and stereotyped, resistance is large, it is long that flow of refrigerant leads to the time of freezing to evaporate dull and stereotyped end, then freeze-off time is long; In heat release defrosting process, easily occur that head temperature is too high and the time is long, end does not also reach defrosting temperature, and overall defrost time is longer, causes defrosting uneven, scars are easily melted.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, heat exchanger time is short, and the evaporation of heat transfer effect uniform multichannel is dull and stereotyped.
The utility model solves the technical scheme that prior art problem adopts: a kind of multichannel evaporation is dull and stereotyped, comprise by the heat-conducting planar of polylith hollow heat conduction flat plate splicing, be provided with dividing plate in the internal cavities of every block hollow heat conduction flat board, the interior separation of hollow heat conduction flat board is become the snakelike transmission channel of continuous print by described dividing plate; The two ends of heat-conducting planar are respectively equipped with feed flow end end socket and air return end end socket, and described feed flow end end socket and air return end end socket are closed hollow structure; Described feed flow end end socket offers the refrigerant inlet be connected with the initiating terminal of snakelike transmission channel in every block hollow heat-conducting plate on madial wall, the madial wall of described air return end end socket offers the cold-producing medium be connected with the end of snakelike transmission channel in every block hollow heat-conducting plate and evaporates and export; Described feed flow end end socket is connected with refrigerant feed liquid end and cold-producing medium return-air transmission pipeline respectively by bend pipe flange with air return end end socket.
The two ends up and down of the two ends of splicing seams between adjacent hollow heat conduction flat board, feed flow end end socket and air return end end socket are equipped with plugging block.
The beneficial effects of the utility model are: the utility model structure is simple, by single-pass configuration form dull and stereotyped for existing evaporation is improved to multi-channel structure form, effectively alleviate because of cold-producing medium circulation flow path line length in evaporation is dull and stereotyped, resistance is the defect that heat exchanger time is long and heat exchange is uneven produced greatly.Experiment proves, the utility model can make freeze-off time shorten 10%, and defrost time shortens 50%, improves scars yield rates, enhances productivity, and reduces energy consumption thus effectively improves the efficiency of heat exchange.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described:
As in Figure 2-4.A kind of multichannel evaporation is dull and stereotyped, comprise the heat-conducting planar be spliced by polylith hollow heat conduction flat board 1, be provided with dividing plate 2 in the internal cavities of every block hollow heat conduction flat board 1, the interior separation of each hollow heat conduction flat board 1 is become a snakelike transmission channel 3 of continuous print by dividing plate 2.During actual fabrication, on the sidewall that one end of dividing plate 2 can be fixed on hollow heat conduction flat board 1, the other end is unsettled, thus in every block hollow heat conduction flat board 1, forms a snakelike transmission channel 3(of continuous print as shown in Figure 4); Feed flow end end socket 4 and air return end end socket 5 is fixed with respectively at the two ends of hollow heat-conducting planar 1.Feed flow end end socket 4 and air return end end socket 5 are closed hollow structure; Feed flow end end socket 4 offers the refrigerant inlet 6 be connected with the initiating terminal of the snakelike transmission channel 3 in every block hollow heat-conducting plate 1 on madial wall; The madial wall of air return end end socket 5 offers the cold-producing medium be connected with the end of the snakelike transmission channel 3 in every block hollow heat-conducting plate 1 and evaporates outlet 7; Feed flow end end socket 6 is connected with refrigerant feed liquid end and cold-producing medium return-air transmission pipeline respectively by bend pipe flange 8 with air return end end socket 7.In order to ensure good inner sealing, the guarantee heat exchanger effectiveness of high degree, between adjacent hollow heat conduction flat board 1, the two ends up and down of the two ends of splicing seams, feed flow end end socket 6 and air return end end socket 7 are equipped with plugging block 9.
Figure 3 shows that internal structure schematic diagram of the present utility model.When the bend pipe flange 8 by feed flow end end socket 6 inputs cold-producing medium in the utility model, cold-producing medium can be entered into each snakelike transmission channel 3 of each hollow heat conduction flat board 1 respectively by each refrigerant inlet 6 that feed flow end end socket 6 madial wall is offered, the steam that cold-producing medium is formed in snakelike transmission channel 3 and by the end of each snakelike transmission channel 3 by cold-producing medium is evaporated outlet 7 through the cryogen corresponding with the end of each snakelike transmission channel 3 and discharged by the bend pipe flange 8 of air return end end socket 7 end.In this course, the snakelike transmission channel 3 that cold-producing medium flows through in every block hollow heat conduction flat board 1 simultaneously carries out reduction vaporization, i.e. circulation heat exchange in the snakelike transmission channel 3 of respective hollow heat conduction flat board 1, effectively shorten length and the resistance of cold-producing medium circulation, namely shorten the currency of cold-producing medium in evaporation flat board.Improve the heat exchanger effectiveness that evaporation is dull and stereotyped.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
