Abstract
The utility model relates to an air convection heat exchanger, wherein a cooling retainer is composed of a plurality of groups of right retainer pieces and left retainer pieces; each two adjacent pieces are misplaced and are in lap joint together mutually from upper side and lower side and from front side and back side. The air convection heat exchanger mainly solves the technical problems that the cooling retainer has the disadvantages of difficult processing and forming, material waste and easy deformation. The cooling retainer can adopt different shapes according to different machine types. The utility model has the advantages of simple manufacturing process, convenient processing, low cost, etc.
Description
Affiliated technical field
The utility model relates to a kind of cross-ventilation heat exchanger, and is particularly a kind of by cold air and hot-air lower the temperature in heat exchanger the convection current of passage separately on the barrier and the cross-ventilation heat exchanger of heat exchange.
Background technology
In the communications industry, the radiating and cooling problem of rack is a very critical technical problems of base station in the base station, though air-conditioning temperature-reducing good cooling effect, but power consumption is high, easy break-down, poor reliability, therefore power consumption is few, is able to extensive use in the radiating and cooling of the heat exchanger of reliable operation rack in the base station of the communications industry.The cross-ventilation heat exchanger that the utility model relates to, it guarantees when can make the cooling machine cabinet cooling that rack inside seals fully, and moisture is avoided in protection rack inside, and the infringement of dust increases the service life.
In the prior art, the cross-ventilation heat exchanger that uses, cooling barrier shape in the radiator has multiple, but the cooling barrier all is after adopting monolithic molding, and upper and lower edge is welded or presses together, and the shortcoming of prior art is cooling barrier difficult forming, waste material, increase manufacturing cost, and cooling barrier poor rigidity, yielding, cooling barrier shaped design is subjected to certain limitation.
Summary of the invention
For overcoming in the prior art, the cooling barrier difficult forming that the cross-ventilation heat exchanger exists, waste material, technological deficiencies such as manufacturing cost is high and yielding, the utility model designs a kind of cross-ventilation heat exchanger cooling barrier structure, cooling barrier that the utility model relates to adopts by the left fence plate of one group of independent processing and the edge interlock of right fence plate or the structure that welds together, owing to adopt said structure, the junction, edge of left side fence plate and right fence plate, play the effect of reinforcement, and the cooling barrier area of the whole processing of fence plate area dwindles greatly, make that processing becomes easily, simply, overcome the deficiency that prior art exists.
The technical scheme in the invention for solving the technical problem is: the cross-ventilation heat exchanger, include: heat exchanger shell, induced draft fan and cooling barrier, the cooling barrier is made up of left fence plate and right fence plate, left side fence plate and right fence plate edge overlap mutually and are interlocked, on the panel of left side fence plate and right fence plate, correspondence is provided with spacing preiection, every adjacent two of left side barrier and right barrier, the cooling barrier above and below, the front and back dislocation overlaps mutually, and constituting lowers the temperature communicates with the front above the barrier, with the air duct that communicates later, left fence plate and right fence plate edge correspondence mutually weld or bond together below.
The beneficial effects of the utility model are, because the cooling barrier in the cross-ventilation heat exchanger adopts the burst combining structure, make every fence plate machine-shaping easy, save material, reduce manufacturing cost, and fence plate can be designed to difformity, louvre edges all mutually towers be connected together, the fence plate edge strength is improved greatly, reach the effect that the fence plate edge is provided with reinforcement.
Description of drawings
Accompanying drawing 1 is the utility model schematic diagram
Fig. 2 is Figure 1B-B generalized section
Fig. 3 is the local enlarged diagram of cooling barrier A
Among the figure, the barrier of 1. lowering the temperature; 2. left fence plate; 3. right fence plate; 4. spacing preiection; 5. radiator casing; 6. cold air induced draft fan; 7. hot-air induced draft fan; 8; . cool air inlet; 9. hot air outlet; 10. hot air inlet; 11. cold-air vent.
Embodiment, referring to accompanying drawing, the cross-ventilation heat exchanger, include: radiator casing 5, cold air induced draft fan 6, hot-air induced draft fan 7 and cooling barrier 1, cooling barrier 1 is made up of left fence plate 2 and right fence plate 3, and left fence plate 2 and right fence plate 3 edges overlap mutually and are interlocked, on the panel of left fence plate 2 and right fence plate 3, correspondence is provided with spacing preiection 4, a left side barrier 2 and right barrier 3 every adjacent two, on cooling barrier 1 and below, the front and back dislocation overlaps mutually, communicate with the front above constituting cooling barrier 1, below with the air duct that communicates later
During work, outdoor cold air is discharged from cold-air vent 11 through cooling barrier 1 cold air channel because 6 effects of cold air induced draft fan enter from cool air inlet 8.Make 1 cooling of cooling barrier.Indoor hot-air is owing to 7 effects of hot-air induced draft fan enter from hot air inlet 10, discharge from hot air outlet 9 through cooling barrier 1 hot-air channel, the hot-air that makes the cooling barrier 1 of flowing through reaches under the situation of sealing air is cooled off being lowered the temperature under cooling barrier 1 effect of chilled air cools.
Before 5 pairs of coolings of heat exchanger shell barrier 1, rear enclosed only flows out hot air outlet 9 and cold-air vent 11.
Because the cross-ventilation heat exchanger adopts above-mentioned operation principle, when cold air and hot-air flow velocity and pressure are big, cooling barrier 1 easily deforms, the utility model cooling barrier 1 adopts said structure, left side fence plate 2 and right fence plate 3 edge strengths improve greatly, reach the effect that the fence plate edge is provided with reinforcement.And left fence plate 2 and 3 machine-shapings of right fence plate are easy.On the panel of left side fence plate 2 and right fence plate 3, the spacing preiection 4 of setting interacts, and keeps the gap between left fence plate 2 and the right fence plate 3 constant, and cooling barrier 1 does not deform.According to different processing needs left side fence plate 2 and right fence plate 3 edges adopting mutual corresponding welding or bond together.
