Description
Technical field
The utility model belongs to heat energy development technique field, relates to a kind of plate-fin heat exchanger.
Background technology
Heat pump is that one can obtain low grade heat energy from natural air, water or soil, through electric power acting, exports the equipment of the high-grade heat energy of energy.Present China mainly utilizes three kinds of heat pump techniques, is water resource heat pump respectively, earth source heat pump, and air source heat pump.
Conventional shell-and-tube heat exchanger, complex structure, bulky, is inconvenient to be applied to indoor grade in minienvironment.
Utility model content
The purpose of this utility model is to provide a kind of plate type heat exchanger, solves existing gas heat-exchanger complicated, is only applicable to gas heater, and is not easy the problem of maintenance.
The technical scheme that the utility model adopts is between two pieces of parallel metal sheets, sandwich some metal fins, metal sheet both sides seal with side slat respectively, the first end socket is provided with above metal fin, the top of metal fin side is provided with the second end socket, below is provided with the 3rd end socket, and the first end socket, the second end socket and the 3rd end socket are provided with stream socket.
Further, described metal fin is straight texture fin, sawtooth texture fin, perforated fin, ripple fin.
Further, described metal fin be arranged as the arrangement of evenly distributed, class interval.
Further, described metal fin is aluminum alloy materials.
The beneficial effects of the utility model are that structure is simple, applied widely, are easy to safeguard.
Accompanying drawing explanation
Fig. 1 is the utility model heat exchanger structure schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model as shown in Figure 1, between two pieces of parallel metal sheets 1, sandwich some metal fins 2, metal sheet 1 both sides seal with side slat 3 respectively, the first end socket 4 is provided with above metal fin 2, the top of metal fin 2 side is provided with the second end socket 5, below is provided with the 3rd end socket 6, first end socket 4, second end socket 5 and the 3rd end socket 6 is provided with stream socket 7.Metal fin 2 is straight texture fin, sawtooth texture fin, perforated fin, ripple fin.Being arranged as of metal fin 2 is evenly distributed, class interval arrangement.Metal fin 2 is aluminum alloy materials.
The heat exchanger that heat transfer element of the present utility model is made up of metal sheet 1 and metal fin 2.Advantage of the present utility model has:
(1) heat transfer efficiency is high, because the disturbance of metal fin 2 pairs of fluids makes boundary layer constantly break, thus has the larger coefficient of heat transfer; Simultaneously due to metal sheet 1 and metal fin 2 very thin, there is high-termal conductivity, so very high efficiency can be reached.
(2) compact, because plate-fin heat exchanger has the secondary surface of expansion, make its specific area can reach 1000 ㎡/m3.
(3) light and handy, reason is compact and mostly is aluminium alloy manufacture.
(4) strong adaptability, plate-fin heat exchanger is applicable to: the phase-change heat-exchange of the heat exchange between gas-gas, solution-air, liquid-liquid, various fluid and the change of generation collection state.Can be adapted to by the layout of runner and combination: the heat-exchanging state that adverse current, cross-flow, multiple flow, multipass flow etc. are different.The heat exchange needs of main equipment can be met by series, parallel between unit, series-parallel combination.Industrially can to shape, to produce in batches to reduce costs, expand interchangeability by building block system combination.
The field that the utility model can be applied has:
For the heat exchanger of air separation plant; The ethylene unit of petrochemical industry, synthetic ammonia installation, natural gas liquefaction and in the device such as being separated; For in the hydrogen of profound hypothermia, helium, refrigeration, liquefaction device; For refrigeration and field of air conditioning; For automobile and aircraft industry; Be worth proposing, at present in departments such as engineering machinery, universal machine, diesel locomotives, plate-fin heat exchanger is widely used in various Oil, Water, Gas body cooler.
The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
