Abstract

The utility model discloses an evaporative condenser with high heat exchange efficiency and belongs to the technical field of refrigeration, and the evaporative condenser is used for solving the problems that heat exchange area of a heat exchange coil is small, heat exchange efficiency is low and the heat exchange coil is easy to scale and corrode in the prior art. The evaporative condenser comprises a shell and a circulating water pump, wherein the inner bottom of the shell is provided with a water collection tank, the upper part of the water collection tank is provided with a heat exchange chamber, a heat exchange coil is arranged inside the heat exchange chamber, watering devices are arranged on the upper part of the heat exchange coil and communicated with the circulating water pump, a cold air machine is fixedly arranged on the upper end of the exterior of the shell, and the heat exchange coil is a stainless steel wave node pipe. In the evaporative condenser with high heat exchange efficiency disclosed by the utility model, the heat exchange area of the heat exchange coil is effectively increased under the condition that the heat exchange coil volume is not increased, so that the heat transmission coefficient is improved; meanwhile, since expansion coefficients of the metal heat exchange pipe and a scale layer are different, when change of alternate heat and cold happened, a strong pulling-out force between the metal heat exchange pipe and the scale layer will be generated, so as to rupture and drop the scale layer, and a strong self-cleaning effect is provided; and in addition, the wave node pipe is made of stainless steel materials and difficult to corrode, and is long in service life.

Description

The evaporative condenser of high heat exchange efficiency
Technical field
The utility model relates to a kind of condenser, particularly a kind of evaporative condenser take the stainless steel wave pipe joint as heat exchange coil.
Background technology
Evaporative condenser is the heat of the interior high-temperature gas cold-producing medium of absorption heat-exchange coil pipe when utilizing the outer shower water of heat exchange coil to evaporate, thereby makes the cold-producing medium in the pipe be cooled to liquid state by gaseous state gradually.Its heat transfer relies on the heat exchange coil surface fully, and normal humid air enters from the evaporative condenser bottom all around with low speed, and to discharge from evaporative condenser top at a high speed, makes the backflow of saturated Hot wet air heating reduce to minimum.
The evaporative condenser that high heat exchange efficiency is arranged in the prior art, comprise housing and water circulating pump, the housing inner bottom part is provided with water leg, water leg top is provided with heat-exchanging chamber, be provided with heat exchange coil in the heat-exchanging chamber, heat exchange coil top is provided with the watering device that is connected with water circulating pump, and air-cooler fixedly is equipped with in the outer upper end of housing.The general heat exchange coil kind that is used for this evaporative condenser has light pipe and finned tube, and tubular have common pipe, elliptical tube and an alternating curved bellows.Light pipe is because inside and outside tube wall is smooth surface, cold-producing medium is laminar condition in tube bank, and generation boundary layer, thermograde namely appears from the tube hub to the tube wall, the appearance in boundary layer greatly reduces the heat transfer coefficient of heat exchange coil, in addition, and under the equal volume, the heat exchange area of the heat exchange coil of this smooth surface is little, and heat exchange efficiency is poor.And with respect to light pipe, though the finned tube of equal volume has increased heat transfer area, be conducive to conduct heat, fin is the device of attached light pipe, need to additionally assemble, safeguards, checks and clean; Elliptical tube has increased heat transfer area and has improved heat-transfer effect, but can't form the Secondary Flow of outer fluid in the pipe, and the convection cell less turbulence increases limited, and the heat exchanging area is used and be insufficient; Alternating curved bellows evaporative condenser make the wetting heat exchange coil of shower water energy maximum area surperficial, thereby heat exchange area increases, make the fluid layer attenuation, increase heat exchange coefficient, but the cold-producing medium turbulent extent in its pipe is still insufficient, so heat exchange effect is also not ideal enough.In addition, various tubular scale problems all are not well solved, and maintenance workload is larger, and service condition still is subject to more restriction.
The utility model content
For overcoming deficiency of the prior art, of the present utility modelly provide the evaporative condenser that the heat exchange coil heat exchange area is larger under a kind of equal volume, heat exchange efficiency is higher and less scaling.
The purpose of this utility model is achieved in that the evaporative condenser of high heat exchange efficiency, comprise housing and water circulating pump, the housing inner bottom part is provided with water leg, water leg top is provided with heat-exchanging chamber, be provided with heat exchange coil in the heat-exchanging chamber, heat exchange coil top is provided with the watering device that is connected with water circulating pump, and air-cooler fixedly is equipped with in the outer upper end of housing, and described heat exchange coil is the stainless steel wave pipe joint.
As further improvement of the utility model, described bellows tube is made of wall thickness identical arc section and straight length.
As further improvement of the utility model, the entrance point of described bellows tube and the port of export are arranged on the same side of heat-exchanging chamber.
In the utility model when work,, water circulating pump is delivered to watering device and spray to bellows tube with the cooling water pressure of water leg, in the entrance point ascending pipe of superheated refrigerant by bellows tube, and detours along pipeline; Normal humid air enters heat-exchanging chamber all around with low speed from the evaporative condenser bottom, fully occur to be converted to saturated Hot wet air heating after the heat exchange with bellows tube, utilizes air-cooler to discharge from evaporative condenser top at a high speed; The superheated refrigerant heat release is converted into liquid state by gaseous state gradually, is discharged by the port of export of bellows tube at last.
Compared with prior art, the beneficial effects of the utility model are: in bellows tube, cold-producing medium is subject to the impact of vortex centrifugal power, so that the cold-producing medium retention layer attenuation of close inside pipe wall, increased the cold-producing medium turbulent extent, the tube wall of bellows tube own is thinner in addition, can significantly strengthen heat transfer coefficient; Outside bellows tube, because the special planform of bellows tube under the equal volume, has larger heat exchange area than other shape heat exchanger tubes, the distinctive crest of bellows tube and trough structure also form turbulence so that be attached to the moisture film on bellows tube surface simultaneously, further enhancing heat transfer; Because bellows tube surfaces externally and internally curvature is large, fluid can produce when flowing that low frequency is little to shake inside and outside bellows tube, destroyed the dirt formation condition, and is less scaling; Even the pipe table forms the dirt layer after long-time the use, because the stainless steel wave pipe joint is different from the coefficient of expansion of dirt layer, when changing when colding and heat succeed each other, will produce larger pulling-out force between the two, can make the dirt layer break, come off, have stronger self-cleaning action, and have the thermal stress automatic compensation function; The stainless steel material corrosion resistance is strong, effectively prolongs the service life of heat exchange coil.
