A kind of hollow cooler
Technical field
The invention belongs to cooler technical fields, are related to a kind of hollow cooler.
Background technique
With the development of motor technology, generator capacity is increasing, and calorific value is also higher and higher, therefore, in generator
When power generation, needs to configure corresponding cooling device and be used to cool down generator, prevent generator from breaking down, extend
The service life of generator.
Existing cooling device, for example, Chinese patent literature data disclose a kind of air-cooled cooler [application number:
201020514119.8;Authorization Notice No.: CN201794757U] comprising wind gathering circle, cooling blower, wind scooper and wind scooper
The cooling unit of lower section installation, cooling unit is made of at least one level single layer cooler, single layer cooler include intake pipe and
Lower inlet duct connects one group of cooling tube being connected to them, the both ends difference of lower inlet duct between intake pipe and lower inlet duct
It is connected with inlet suction port and air outlet adapter;Be respectively equipped with 1-3 partition in intake pipe and lower inlet duct, intake pipe under into
Endotracheal partition formation is staggered, and one group of cooling tube is divided into and is contacted by upper and lower air inlet pipe by staggered partition
Cooling tube group.
The air-cooled cooler of this kind of structure includes cooling tube, is entered in cooling tube by the cold air that cooling blower generates
Cool down cooling tube to compressed air.But the air-cooled cooler of this kind of structure, it is carried out when to lower-powered generator
When cooling, the negligible amounts of cooling tube, when cooling down to the biggish generator of power, the quantity of cooling tube is more, this is just
The position of intake pipe, lower inlet duct and connection frame etc. is caused to require to make corresponding adjustment, to make the wind of this kind of structure
The size of cold cooler needs to redesign when can be cooled down for different generators, and the outer dimension of cooler changes greatly,
Consistency is poor, and needs design iterations, design trouble.
Summary of the invention
The purpose of the present invention is being directed to the above-mentioned problems in the prior art, a kind of hollow cooler is proposed, is solved
The technical issues of be how to reduce the trouble of hollow cooler design iterations.
Object of the invention can be realized by the following technical scheme: a kind of hollow cooler, including vent cabinet, centrifugation wind
Machine and axial flow blower, which is characterized in that upper perforated plate is fixed at the top of the vent cabinet, bottom is fixed with lower perforated plate, described logical
It is equipped with partition in wind cabinet, there are vent passages between the bottom and lower perforated plate of the partition, the partition is by the sky in vent cabinet
Chamber is divided into the vented cavity and installation cavity of left and right settings, is provided with multiple heat exchanger tubes, Duo Gehuan along the vertical direction in the installation cavity
The both ends of heat pipe are fixedly connected with upper perforated plate and lower perforated plate respectively, and the bottom of multiple heat exchanger tubes has cold wind import, multiple heat exchanger tubes
Top exported with cold wind, the axial flow blower is located at cold wind exit, the top of the vent cabinet side wall be provided with hot wind into
Mouthful, it is also provided with hot-blast outlet on the vent cabinet, the hot wind inlet is gone out by installation cavity, vent passages and vented cavity and hot wind
Mouth is connected, and the centrifugal blower is located at hot-blast outlet.
Vent cabinet is divided into the vented cavity and installation cavity of left and right settings by partition, and installation cavity is used to install heat exchanger tube, axis stream wind
Machine drives extraneous cold air to enter in heat exchanger tube from cold wind import and exports discharge from cold wind again, and centrifugal blower will be in generator
Hot-air be drawn into installation cavity from hot wind inlet, the cold air in installation cavity in hot-air and heat exchanger tube carries out hot friendship
It changes, to reduce the temperature of hot-air, the hot-air after being cooled down enters vented cavity from vent passages, then passes through centrifugation wind
Machine re-enters into generator, cools down to generator, and the air themperature carried out after heat exchange with generator increases again,
Entering in installation cavity again by hot wind inlet and carrying out heat exchange, cycle heat exchange, and cold air is under in vent cabinet
