Summary of the invention
Problem to be solved in the utility model provides a kind of communication cabinet that improves the heat exchanger of heat exchange property in the rack and use this heat exchanger.
The technical scheme that the utility model adopted is: heat exchanger, comprise the heat exchanging core in heat exchanger shell and the heat exchanger shell, heat exchanging core and heat exchanger shell form the interior circulation air path and the outer circulating air duct of mutual isolation, interior circulation air path and outer circulating air duct are equipped with air inlet and air outlet, the air inlet place is equipped with interior circulating fan in the interior circulation air path, the air inlet place is equipped with the outer circulation fan in the outer circulating air duct, the interior circulating fan that install at the air inlet place in the circulation air path in described is an aerofoil fan, circulation air path air inlet and interior circulation axis flow fan are obliquely installed in described, thereby circulation air inlet position and equipment frame top are substantially in one plane in making, and inner circulating air enters heat exchange core body by directly turning to after the interior circulating fan of placing by certain angle.
In the such scheme, the outer circulation fan that install at the air inlet place in the described outer circulating air duct is a centrifugal fan, and it is 0 °～90 ° that described interior circulation axis flow fan and core body air intake plane inclination are placed angle.
The technical scheme that communication cabinet adopted that the utility model is used this heat exchanger is: communication cabinet comprises the heat exchanger cabin, equipment compartment and supporting cabin, heat exchanger is provided with heat exchanger in the cabin, described heat exchanger comprises the heat exchanging core in heat exchanger shell and the heat exchanger shell, heat exchanging core and heat exchanger shell form the interior circulation air path and the outer circulating air duct of mutual isolation, interior circulation air path and outer circulating air duct are equipped with air inlet and air outlet, the air inlet place is equipped with interior circulating fan in the interior circulation air path, the air inlet place is equipped with the outer circulation fan in the outer circulating air duct, the interior circulating fan that install at the air inlet place in the circulation air path in described is an aerofoil fan, and the circulation axis flow fan was obliquely installed in described interior circulation air path air inlet reached.
In the such scheme, the outer circulation fan that install at the air inlet place in the described outer circulating air duct is a centrifugal fan, and it is 0 °～90 ° that described interior circulation axis flow fan and core body air intake plane inclination are placed angle.
The beneficial effects of the utility model are: circulation air path adopts aerofoil fan in the utility model, be obliquely installed with interior circulation air inlet simultaneously, thereby eliminated the narrow and small zone on the interior circulation air path, reduced the inner circulating air flow resistance, inner circulating air enters heat exchange core body by directly turning to after the interior circulating fan of placing by certain angle, has improved the heat exchange property of heat exchanger.
