In heat exchanger described in the utility model, the air outlet of the outer circulation of the external circulation air inlet of described heat exchange core correspondence and the heat exchange core that is adjacent is non-conterminous.
In heat exchanger described in the utility model, the plane, inlet and outlet place of described outer circulating air duct is adjacent or relative with described interior plane, circulation air path inlet and outlet place.
In heat exchanger described in the utility model, be provided with dividing plate between the adjacent described outer circulating air duct.
In heat exchanger described in the utility model, described distributary heat exchange core is two, comprises the first distributary heat exchange core and the second distributary heat exchange core.
In heat exchanger described in the utility model, corresponding first outer circulating air duct of the described first distributary heat exchange core, corresponding second outer circulating air duct of the described second distributary heat exchange core.
In heat exchanger described in the utility model, the air inlet of the air outlet of described first outer circulating air duct and second outer circulating air duct is non-conterminous.
In heat exchanger described in the utility model, be provided with dividing plate between described first outer circulating air duct and second outer circulating air duct.
In heat exchanger described in the utility model, also comprise the fan that is arranged in the air channel.
In heat exchanger described in the utility model, described fan is an aerofoil fan.
Implement heat exchanger of the present utility model, has following beneficial effect: because heat exchanger of the present utility model has adopted two and plural distributary heat exchange core and all corresponding independently described interior circulation air path of each described distributary heat exchange core and an independently described outer circulating air duct, the number that is used for powerful heat exchange and only need increases distributary heat exchange core gets final product, and can not cause heat exchange efficiency to reduce because of the excessive increase that distributary heat exchange core piles up the number of plies; Adopt aerofoil fan simultaneously, realize carrying out the requirement of uniform high-efficiency air-flow exchange, have the high advantage of high efficiency, low cost and reliability with electronic equipment internal.
