Embodiment
Supply air system as shown in Figure 1, including cold accumulation cold source 11, heat pipe evaporator 12 and blower fan 13.
Water is become ice by refrigeration modes and converts electrical energy into cold storage by cold accumulation cold source 11.The composition of cold accumulation cold source can
Be by refrigeration modes such as compression-type refrigeration, semiconductor refrigerating, absorption refrigerations, by electric energy carry out be converted into cold.Pass through
Heat exchange, is absorbed to cold by the material (such as water or other solids) of cold-storage, is changed into its sensible heat or latent heat
Store, constitute cold accumulation cold source.Cold accumulation cold source needs certain heat insulating effect, places the cold of storage and the external world
Environment occurs heat exchange and produces energy loss.
By heat pipe 14 and therewith, close-fitting fin 15 is constituted heat pipe evaporator 12, and heat pipe adopts the cold of cold accumulation cold source
The transmission of cold is carried out with solid heat transfer mode, and solid heat transfer is carried out by fin closely coupled thereto, whole heat pipe is formed
The uniform temperature field of evaporator.
It is internal between the heat pipe of each in heat pipe evaporator that the circulatory mediator for being used for transmitting cold is not present, simply by heat pipe Lai
Heat transfer.A heat pipe part for heat pipe evaporator is stretched into cold accumulation cold source, the material (such as water or other solids) with cold accumulation cold source
Good contact is formed, is easy to the cold of cold accumulation cold source to pass to heat pipe.In order to realize good heat transfer effect, Ke Yizeng
The quantity of heating tube, the length for stretching into cold accumulation cold source, the shape of heat pipe and fin etc. increase contact of the heat pipe with cold accumulation cold source
Area.
Heat pipe evaporator such as when making except, using techniques such as tubes, making fin be in close contact with heat pipe, reducing heat transfer
Outside thermal resistance, heat transfer area can be increased using multigroup fin.
Heat pipe evaporator simultaneously can also using it is parallel it is multigroup by the way of, according to the size progress of required transmission cold
Match somebody with somebody, for needing pipeline UNICOM using circulatory mediator in traditional sense, can quickly realize the Rapid matching of heat exchange area.
Blower fan 13 is by the cold for the homogeneous temperature field for being formed heat pipe evaporator and sky by the way of forced convertion
Heat is swapped in gas, and one side air absorbs the cold of heat pipe evaporator, realizes temperature reduction；Another aspect heat pipe steams
Hair device absorbs the heat in air, is constantly exchanged heat with the cold of cold accumulation cold source by solid heat transfer, so that
Cold accumulation cold source is realized to exchange with the cold and hot of air.
The rotating speed of blower fan is can to carry out, across level or stepless speed regulation, thus producing different air quantity, the size of air quantity is not
Together, the degree of air themperature reduction is different, then different from the cold wind air themperature formed after surrounding air mixing, the cold wind of generation
Wind speed and thus bring effect just different.If cold accumulation cold source is mixture of ice and water, then heat pipe evaporator surface temperature base
This is at 0 DEG C, if circulated using forced convertion, and the cold wind produced by boasting can come low than the cold wind temperature of air-conditioning in traditional sense
Many, the comfort given people is poor.If now the cold wind of the hot air temperature reduction of reduction wind speed or introducing surrounding is carried out
Mixing, the temperature of cold wind can have been raised, and the comfort given people will improve.
Supply air system realizes suitable matching, Jiu Huiying in heat pipe evaporator heat exchange surface area and blower fan wind speed (air quantity)
Make a suitable or required air-supply effect.The power supply of supply air system can also use battery, to realize the shifting of air-conditioning
It is dynamic to use.

The groove 6 that bar coordinates；It is corresponding, the fitting recess of setting-in flexible sealing strip 5 is provided with grid shell 3, is easy to flexible sealing strip 5
Installation fix.
In the present embodiment, grid shell 3 is made by plastics such as HIPS, ABS or PP rather than with metal material, so as to lattice
In grid shell 3 space of insulation (need) (environment) does not form cold bridge outside, carry out heat transfer.Grid wall is relatively thin, inner hollow,
To fill heat-barrier material 4；The heat-barrier material can be that EPS foamings foamed plastics can also fill grid shell with PU,
Form good heat-insulating property.Grid shell 3 can be integral extrusion shaping, can also make to be spelled in the way of snap-fastener by two parts
Conjunction is formed, and is easily installed.Grid shell makes each grid shell not interference structure in rotation, while in closure, grid
There is good sealing between grid；When opening, grid rotates inclination and had a certain degree, and can send out cold wind.
In the present embodiment, flexible sealing strip 5 is T-shaped sealing strip, and flexible sealing strip is arranged on grid shell, is turned in grid
During dynamic closure, extruding force is formed between grid and grid, flexible sealing strip is deformed, so as to prevent in grid shell (to need to protect
The space of temperature) (environment) air outside flowing, place heat exchange type into the loss of energy.
Grid end cap is used for the end for covering on grid shell, on the one hand can prevent when heat-barrier material is filled, heat-insulated material
Material is excessive；The moving components such as another aspect grid end cap and grille frame or stepper motor are connected, realize the motion of grid with
Upset.
In the present embodiment, gear, the gear and motor linkage of one of rotating shaft, phase are installed in the rotating shaft of each grid
The synchronized V belt translation of gear of adjacent two grids.Grille frame is the matrix that grid is installed, the moving component such as it is with stepper motor
It is connected, realizes the motion and upset of grid.Shell installation site of the grille frame again with product of blowing mutually is fixed simultaneously, so that shape
Match into a part with air-supply product.
Preferable implementation example of the present utility model is the foregoing is only, the utility model is not limited to, it is all in this reality
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
