Abstract
The utility model relates to a plastic board heat exchanger with indirectly evaporative cooling, which is a heat exchanger for an air conditioner. The utility model is characterized in that a heat exchanger fin core is tightly pressed by a metal frame and adheres the core to the frame along the upper hem and the lower hem of the frame by a leak proof sealing gum; the heat exchange fin core is composed of many heat exchanger fins according to same direction; each heat exchanger fin is compounded by that two plastic plates with taper-shaped protruding objects equably distributed on the plated surfaces are mutually crossed into 90DEG, and then two non-adjacent edges of each plastic plate are folded of pressed by heat along the direction of the protruding objects. The utility model has the advantages of convenient operation, management and maintenance, low initial investment, etc.
Description
Indirect evaporation cooled plastic plate type heat exchanger is a kind of idle call heat exchanger.
In air-conditioning system, having 30～40% energy to be used for handling new wind load approximately reaches with the resh air requirement that guarantees air-conditioning system and is not less than 15% design specification requirement, but for energy-conservation, the new wind of some air-conditioning system is closed for a long time, cause room air pollution serious, in order to solve this contradiction, just must in VMC, set up heat reclamation device, to reclaim the energy that air draft is taken away, thereby just can guarantee to save a large amount of electric energy under the room air sanitary condition, this heat reclamation device has two classes: a class is a rotary type total heat exchanger, its shortcoming is that volume is big, and resistance is also big and initial cost is also high, and another kind of is the heat pipe-type sensible heat exchanger, but its thermal efficiency is low, the inconvenience management, operation and maintenance.In the beginning of this century, in order to solve xeothermic regional cooling problem, someone has proposed a kind of air conditioner refrigerating method of indirect evaporation cooling, spray room air with recirculated water exactly, because a large amount of heat absorptions of evaporation of water all decrease the outside air temperature of air themperature and heat exchanger fin temperature and opposite side, the outdoor air that is cooled is when reducing temperature, its water capacity remains unchanged, enthalpy reduces, just realized refrigeration, though and directly evaporative cooling the temperature of air is reduced, the water capacity of air increases, its enthalpy is constant substantially, so can not freeze, but when specific implementation, because the heat exchanger size was big at that time, fouling blocking pipe in service, material, problems such as equipment do not solve, and the method that this indirect evaporation is cooled off can't practicability.
In order to make the method practicability of indirect evaporation cooling refrigeration, the utility model proposes the board-like indirect evaporation cooled plastic plate type heat exchanger of a kind of air-air.In the heat exchanger, only allow air along passing through in the passage that is not closed on the direction alternate passage sealing, and on other direction, then second half alternate passage sealing, the two-way air is not mixed mutually mutually, at this moment, as long as the moisture film that is constantly flowing on secondary air draft that two passages are sent into once new wind and carried shower water simultaneously secretly just can be by means of the plate face respectively along different directions has been realized the indirect evaporation air conditioner refrigerating.
Heat exchanger generally comprises heat exchanger fin fuse and two parts of outer cover of heat exchanger, of the present utility model being characterised in that: it is a kind of frame-type plastic plate type heat exchanger based on indirect evaporation cooling air conditioner refrigerating principle, its each heat exchanger fin be have two identical, the plastic board of uniform taper turbulent flow protrusion intersects mutually after 90 ° along two non-conterminous limits of protrusion every plastic plate of steering handle up that folding accordingly or hot pressing forms on the plate face.
Facts have proved: this heat exchanger is the efficient height not only, and owing in air-conditioning system, can replace compressor and surface cooler in the vapour compression refrigeration unit with water pump and blower fan, thereby all be very economical on operating cost still from initial cost, and operation, management and maintenance are all very convenient.
, existing that employed accompanying drawing number of the utility model and title brief introduction is as follows for below in conjunction with the embodiments to the more detailed description of the utility model do:
Fig. 1, heat exchanger fin plane;
The A-A profile of Fig. 2, heat exchanger fin;
The B-B profile of Fig. 3, heat exchanger fin;
Fig. 4, taper protrusion enlarged drawing.
Embodiment:
Ask for an interview Fig. 1～4.Thin shaped plastics heat exchanger fin as shown in Figure 1 of method system with the mould of plastics injection moulding.The 1st, heat exchanger fin, the 2nd, taper turbulent flow protrusion, each row is equally distributed to taper turbulent flow protrusion in plate face upper edge, and adjacent two row to compare be that the ratio of bottom width and height of this protrusion of cross-distribution is 1:1, immediate two protrusions half pitch of being separated by between adjacent two row, said here spacing is meant the distance between adjacent two protrusions in each row, four jiaos of strut angles that are square that " └ " or " ┐ " shape are all arranged of each heat exchanger fin are to guarantee the gap between sheet.Each heat exchanger fin is that the plastic board by uniform taper protrusion on two identical, plate faces intersects mutually behind 90 degree that two non-conterminous limits of every block of plate of steering handle are correspondingly folding or hot pressing is synthetic along protrusion up again, and then uses leakproof seal glue bonding fuse and framework along upper and lower respectively four limits of framework after with a metal (also can be plastics) framework the heat exchanger fin fuse of being made up of many heat exchanger fins being compressed again.Above-mentioned this turbulent protrusion also can adopt and be corrugated hemispheric, promptly two identical hemisphere of heaving and recessed hemisphere are connected to corrugated one by one and get final product, and also can be parabolical, if represent its heat exchanger efficiency with ∈, and ∈=(t then
H.i-t

Then experiment records: ∈=0.70-0.85
Can realize refrigeration as long as make once new wind become level to send into from different air ducts with the secondary air draft that clips shower water during use with square crossing ground.
