Abstract
The utility model relates to a high-efficiency heat exchanger, which belongs to the technical field of air exchangers of communication equipment, and comprises a machine body shell and an air current crossed heat exchanger core provided with an inner air current path and an outer air current path which are mutually vertical and completely and independently separated. The high-efficiency heat exchanger is characterized in that centrifugal fans are arranged on the upper side and the lower side of the core; an internal circulation system and an external circulation system are respectively closed and partitioned by a partition board; the partition board is designed to cover one part of turbine scroll shapes of the centrifugal fans; a core central shaft and the machine body shell form an inclined angle of 45 degrees; and the outlet air direction of the centrifugal fans is parallel to the outlet and inlet direction of the core air current. In the utility model, the placing position of the core is rotated by 45 degrees and matched with the internal and external centrifugal fans to obtain the maximum air current value and reduce the wind resistance to maximum extent, thereby improving the overall efficiency of the centrifugal fans and the heat exchanger; and through the comparison, the efficiency is improved by 20 to 30 percent.
Description
Technical field
The utility model belongs to the brethaid technical field of communication apparatus, is specifically related to a kind of crosscurrent heat exchanger.
Background technology
Air heat exchanger is widely used in industries such as communication room external equipment, medical treatment, food industry.Heat exchanger generally is made up of critical pieces such as centrifugal blower, heat exchanger core, housings.The air channel design of heat exchanger, integral layout will directly have influence on the efficient of heat exchanger.
At present, because the housing of heat exchanger product generally processes by sheet metal part, external form is based on Founder (as shown in Figure 1), each surperficial right angle intersection.And blower fan is generally over against the heat exchange movement.Such version causes the gas channel abrupt change of cross-section that enters heat exchanger inside, thereby has increased gas-flow resistance, reduced air velocity, and then influences the whole heat exchange efficiency of equipment.
Summary of the invention
The utility model purpose is to have maximum heat transfer ability, air path crosscurrent heat exchanger smoothly in order to overcome the defective of above-mentioned prior art, to provide.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of efficient heat exchanger, comprise body shell, air-flow staggered form heat exchanger movement with interior air flow path orthogonal, that independently separated fully and outer air flow path, it is characterized in that movement is provided with centrifugal blower in both sides up and down, by dividing plate internal circulation system and external circulating system sealing are separated, described baffle design is the part of the scroll shape of covering centrifugal blower, movement central shaft and body shell are 45 degree angles, and described centrifugal blower exports into wind direction parallel with movement air-flow gateway direction.
Movement of the present utility model can adopt aluminium sheet formula heat exchanger movement, and the placement angle of movement and body shell are 45 degree angles, and has made full use of the effect that centrifugal blower uses as air blast after covering volute, so that reaches high as far as possible drafting efficiency.
Heat exchanger compared to existing technology, the beneficial effects of the utility model are behind movement placement location rotation 45 degree, cooperate with inside and outside centrifugal fan to obtain maximum air flow value, efficiency optimizationization, have maximum thermal heat transfer capability, rational deployment is done overall volume more compact simultaneously.In the convenience that both guarantees panel beating, at utmost windage is reduced; Thereby improved the whole efficiency of blower fan and even heat exchanger.Through contrast, raise the efficiency 20%-30%.

Description of reference numerals: plate type regenerator core 1, casing 2, interior circulating fan 3, outer circulation blower fan 4, upper spacer 5, lower clapboard 6.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The decussate gas of heat exchanger is by adjacent two fin intersectings and two groups of opposite side hermetic seal cooperations respectively to gas total-heat exchanger movement 1 as depicted in figs. 1 and 2, forms two groups of air channels that isolate mutually between the fin.It is stacked that adjacent two fin turn over turnback, and two inside and outside circulatory systems are strictly separated, so that keep the closure of inside and outside circulation, avoids the air in two passages to mix.When the hot-air in the cabinet passes through the inner cycle channel of radiator, also there is cold relatively air to pass through in the outer circulation passage, heat will pass through fin conductive like this, and blow out casing with cold relatively air, form crosscurrent, and then when in a single day cabinet temperature surpasses environment temperature, just spread heat is fallen, find out movement heat exchanger fin and body shell 2 sidewall vertical direction settings as Fig. 1 and 2.
The utility model shown in Figure 2 is with the heat exchange movement of Founder, install after rotating 45 °, movement is provided with centrifugal blower in both sides up and down, top is interior circulating fan 3, the bottom is an outer circulation blower fan 4, circulating fan 3 is communicated with the working space of regulator cubicle sealing in the assembling back, and the moving air of regulator cubicle is delivered to heat in the rack the interior air flow path of movement.Outer circulation blower fan 4 is communicated with the outer air flow path of movement, and with external environment connect, inside and outside air flow path is made by the thin good aluminium foil of heat conductivility, and the heat of interior air flow path is delivered to outer air flow path very soon, realizes heat exchange.
In casing, by upper spacer 5, lower clapboard 6 internal circulation system and external circulating system sealing are separated, described baffle design is the part of the scroll shape of covering centrifugal blower.Behind movement placement location rotation 45 degree, air stream outlet and dividing plate join, and make air more smooth.
The inside and outside centrifugal fan of the utility model heat exchanger can guarantee maximum air flow value, and offsets the hyperbar resistance in intensive electronic component rack in Cabinet is used, thereby has improved the whole efficiency of blower fan and even heat exchanger.The cyclic space can protect closed equipment to avoid the heat under various hostile environments and the influence of airborne pollutant in enclosed, so that an environment that closed equipment is worked under optimum temperature is provided.
