The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing:
As shown in the figure, this heat-exchange system mainly is made up of heat exchanger and air-conditioning, and wherein heat exchanger is made up of outer air channel blast pipe 1, shell 2, interior air channel air inlet 3, exogenous wind road discharge pipe 4, blower fan 5, heat exchanger core 6 and interior air channel discharge pipe 7; Wherein heat exchanger core 6 is key technologies, heat exchanger core 6 is made up of fin (square plate) 61 and corner fittings 62 that several layers has 4 flangings, in four flangings of fin, upwards folding (upper hem 611) of two corresponding sides is arranged, two corresponding sides folding (lower hem 612) downwards then in addition, the direction of four of Dui Jie fin flangings is opposite with it, promptly two boards not in the same way the flanging butt joint fix through corner fittings 62 again and just formed the two kinds of air channels that can change mutually, air channel in a kind of, another kind of outer air channel.
Operation principle
The operation principle of native system is sufficiently and reasonably to utilize the temperature difference of base station/machine room indoor and outdoor, forms the mutual transmission of heat.Hot blast in the blower fan suction chamber at first interior air channel; during by heat exchanger core; heat is delivered to air or other mobile objects of coming in outer air channel; wind or other mobile objects by outer air channel takes the external world to again; thereby realized under the prerequisite in having completely cut off outdoor dust inlet chamber fully; reached outdoor and indoor cold and hot exchange; reduce the purpose of machine room internal temperature effectively; thereby under the prerequisite of guaranteeing the normal operation of machine room internal unit; reduce the service time of air-conditioning as far as possible; reach the purpose of saves energy, can prolong the service life of air-conditioning simultaneously at double, reduce or cancel standby air-conditioning configuration.
Blower fan is brought into the outer circulation passage of layered laminate with the cold air in the external world, cools off heated fin, goes out hot blast from another section of outer circulation.In interior circulation, blower fan is brought into the hot blast of confined space in the interior circulation of layered laminate, is cooled by by the fin of the cold wind of outer circulation cooling the time, cold wind is sent in the confined space, thereby arrived effect to the confined space heat radiation.In this core body, inside and outside circulation canal is the layered laminate of each interval, can arrive high radiating efficiency, and the characteristics that do not interfere with each other are arranged again.
For example, heat exchanger starts when detecting temperature greater than 25 ℃, and heat exchanger cuts out when starting the back temperature less than 20 ℃; Air-conditioning 1 starts when detecting temperature greater than 30 ℃, and air-conditioning 1 is closed when starting the back temperature less than 25 ℃; Air-conditioning 2 (standby) starts when detecting temperature greater than 35 ℃, and air-conditioning 2 is closed when starting the back temperature less than 31 ℃.The protection temperature control is greater than 35 ℃ of closures, less than the Kick type temperature control of 33 ℃ of disconnections, guarantees to start air-conditioning 1 and air-conditioning 2 during greater than 35 ℃ in temperature when environmental monitoring is out of order.
