The specific embodiment
The energy-saving heat-exchange equipment that is used for air-conditioning system that the present invention proposes is described as follows in conjunction with the accompanying drawings and embodiments.
As shown in Figure 1, the energy-conservation heat-exchanger rig that is used for air-conditioning system provided by the invention mainly comprises: thermal insulation board 1, the cavity of this heat-exchanger rig in the air-conditioning is divided into two chambers independent of each other up and down, be respectively outdoor heat exchange chamber 4 and indoor heat exchange chamber 5, thermal insulation board 1 is represented outdoor heat exchange chamber 4 with top among the figure, be located at the exterior space during installation, thermal insulation board 1 is represented indoor heat exchange chamber 5 with the lower part, be located at the interior space during installation, as shown in Figure 3, the cabinet shell 9 of air-conditioning is pressed close to the metope of both sides, and fixes with the mounting plane of the level of both sides by the mounting flange 10 of both sides; Some heat-transfer pipes 2, every heat-transfer pipe 2 one ends stretch into outdoor heat exchange chamber 4, the other end stretches into indoor heat exchange chamber 5 by thermal insulation board 1, be injected into refrigeration working medium in the heat-transfer pipe 2, like this, each root heat-transfer pipe 2 couples together outdoor heat exchange chamber 4 and indoor heat exchange chamber 5, and refrigeration working medium just can circulate for 2 li at each root heat-transfer pipe, and loop direction is as shown in Figure 2 under the gravity effect for refrigeration working medium; Communicating pipe 3 is communicated with an end of the every heat-transfer pipe 2 that is positioned at outdoor heat exchange chamber 4, and the end of communicating pipe 3 is provided with opens shutoff device, can be in the opening and closing two states; After air-conditioning equipment installs, by communicating pipe 3 pairs of heat-transfer pipes 2 vacuumize, other medium in the heat-transfer pipe 2 is drained only, then by communicating pipe 3 pairs of heat-transfer pipes, the 2 interior liquid refrigeration working medium that fill, guarantee to have only in the heat-transfer pipe 2 a kind of medium of refrigeration working medium, as adopt refrigeration working medium F-22 (R22), and closed after communicating pipes 3, inlet added refrigeration working medium, make heat-transfer pipe 2 be in closed state.
Heat-transfer pipe 2 employing U type pipes in the present embodiment in the present embodiment, as shown in Figure 4, communicating pipe 3 is to be connected together by several less U type pipes of outside and heat-transfer pipe 2 to constitute, and heat-transfer pipe 2 is connected together by communicating pipe 3 in the outside.
In the present embodiment, be set with outdoor heat exchange fin 6 on the heat-transfer pipe 2 in outdoor heat exchange chamber 5, on the heat-transfer pipe 2 of indoor heat exchange chamber 4, be set with indoor heat exchange fin 7, because each heat-transfer pipe 2 stretches in outdoor heat exchange chamber 4 and the indoor heat exchange chamber 5 simultaneously, make indoor heat exchange chamber 5 and outdoor heat exchange chamber 4 shared each root heat-transfer pipe 2, the cold working medium of work schedule is carried out closed circulation up and down in every heat-transfer pipe 2, make every heat-transfer pipe 2 respectively as fluid collection tube and gas collecting pipe.
The next door of outdoor heat exchange chamber 4 and/or indoor heat exchange chamber 5 is equipped with blower fan 8, and the blower fan of being installed 8 is axial flow blower or centrifugal blower.Blower fan 8 is installed at indoor heat exchange chamber 4 places, is used for accelerating the circulation rate of indoor (as the base station) interior air, thereby accelerates the process of refrigerastion of indoor temperature and the heat transfer efficiency of raising heat exchanger; Simultaneously, because after blower fan 8 is installed, has quickened process of refrigerastion, improved the heat transfer efficiency of heat exchanger, so can dwindle the complete machine size of air-conditioning equipment, this is very important for the narrow and small relatively communication base station in space.In addition, for outdoor heat exchange chamber 4, for dwindling the volume of complete machine, reach better heat-transfer effect, the blower fan 8 of forcing heat transfer also can be installed, this blower fan 8 is generally selected axial fan for use.
Adopted the design of minor diameter communicating pipe in the present embodiment, can adopt the cross section is circular communicating pipe, and the general diameter range that adopts is 3～4.5mm, it is little that the diameter of communicating pipe 3 designs, make air-conditioning heat exchanger tube coil pipe diminish, improve the unit are heat output, the space is saved in the machine integral installation.
The above-mentioned energy-conservation heat-exchanger rig that is provided in the present embodiment adopts indoor heat exchange chamber 5 and outdoor heat exchange chamber 4 to be integral type, separate by heat-insulating shield 1 in the middle of the two, be installed in the air-conditioning system, be fit to air-conditioning is installed in big indoor of communication base station or other heat dissipation capacity.
Communication base station is generally a confined space for consideration such as dustproof, rainproof, antitheft, and draught capacity is very poor in other words, in addition because a large amount of electronic devices and components work heat radiation, so if communication base station does not adopt the refrigeration measure, temperature often is higher than outside air temperature far away in it.Therefore present embodiment adopts refrigeration working medium circularly cooling in heat-transfer pipe 2 according to these characteristics of base station.With reference to figure 2, the arrow that makes progress among Fig. 2 is represented vaporized gas, downward arrow is represented the liquid of condensation, when indoor hot gas under the effect of blower fan 8, hot-air is during by indoor heat exchange chamber 5, simultaneously carry out heat exchange with the liquid refrigerating working medium that is positioned at indoor heat exchange chamber 5 heat-transfer pipes 2, liquid refrigerating working medium is evaporated to gas refrigeration working medium after absorbing heat, and enter into heat-transfer pipe 2 in the outdoor heat exchange chamber 4 from bottom to top, carry out exchange heat by outdoor heat exchange chamber 4 and outdoor cold air, release heat, liquefaction is liquid, liquid refrigerating working medium be easy to from top to down pass through outdoor heat exchange chamber 4, because the installation site of outdoor heat exchange chamber 4 is than the installation site height of indoor heat exchange chamber 5, under the effect of gravity, liquid refrigerating working medium flows to the heat-transfer pipe 2 that is positioned at indoor heat exchange chamber 5 by the heat-transfer pipe 2 that is positioned at outdoor heat exchange chamber 4, thereby circulates.By the process that refrigeration working medium circulates in heat-transfer pipe 2, therefore the hot-air in the communication base station has reached the purpose to the communication base station cooling owing to the heat absorption of refrigeration working medium is lowered the temperature.
As can be seen from the above embodiments, evaporation and the condensation of present embodiment by refrigeration working medium is delivered to the heat in the communication base station outdoor, reaches the purpose of communication base station room temperature lowering.Because present embodiment is to utilize the cooling that circulates of the natural quality of refrigeration working medium, except that blower fan 8, do not need other energy, so have energy-conservation characteristics, in addition, have cooling and be not subjected to the restriction of time, guaranteed to communication base station for a long time, cooling efficiently, and keep the indoor cleaning in base station.
Above embodiment only is used to illustrate the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the spirit and scope of the present invention; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
