It changes, flows to supplementary heat exchanger 74 after so that heat exchange oil is cooled down in water cooling heat exchanger 72.Supplementary heat exchanger 74 is radiated to surrounding air
Cold source discharges the cold source that heat exchange oil keeper carries by supplementary heat exchanger 74, and then the heating of heat exchange oil reenters water cooling heat exchanger 72
It is cooled down.That is, heat exchange oil flows between water cooling heat exchanger 72 and supplementary heat exchanger 74, by the cold source in water cooling heat exchanger 72
It brings into supplementary heat exchanger 74, cools down to the second accommodating chamber 13.Specifically, heat exchange oil is thermally conductive good and non-conductive, it is assumed that heat exchange
Oil is revealed in the second accommodating chamber 13, will not generate security implication to the second electric appliance mould group 90.
Further, cold source transfer unit 73 further includes second circulation blower 76, and the electronic auxiliary of second circulation blower 76 is changed
Cold air stream around hot device 74 quickly takes the cold air around supplementary heat exchanger 74 to second electricity to the second electric appliance mould group 90
Near device mould group 90, is quickly and effectively cooled down to the second electric appliance mould group 90, cooling capacity is avoided to concentrate on around supplementary heat exchanger 74,
And keep the cooling response speed of the second electric appliance mould group 90 slack-off.
Specifically, cold source transfer unit 73 further includes the second air duct 78, and the second electric appliance mould group 90 is set in the second air duct 78,
Second circulation blower 76 drives air to be flowed by supplementary heat exchanger 74 between the first electric appliance mould group 50 and supplementary heat exchanger 74
To the second electric appliance mould group 90, the cold air around supplementary heat exchanger 74 is driven to the second electric appliance mould group 90, to the second electricity
Device mould group 90 cools down.Meanwhile air-flow is assembled by the second air duct 78, make more the second electric appliance of air flow direction mould groups
90, improve heat dissipation effect.In second accommodating chamber 13, air-flow is flowed in the second air duct 78 by 78 periphery of the second air duct, then again from
The outflow of second air duct 78, is circulated, and is guaranteed the mobility of air in the second accommodating chamber 13, is made in the second accommodating chamber 13
Temperature is more uniform.
Further, the first air duct 36 and the second air duct 78 are respectively for first circulation blower 34 and second circulation blower 76
One end be in horn-like setting, to introduce more air-flows.
In some embodiments, the first accommodating chamber 11 and the second accommodating chamber 13 are closed chamber, and shell 10 is thermal insulator, the
One accommodating chamber 11 and the second accommodating chamber 13 are isolated from the outside world heat transfer.Firstly, shell 10 is thermal insulator, the first accommodating chamber 11
It is closed chamber with the second accommodating chamber 13, prevents the first accommodating chamber 11 and the second accommodating chamber 13 inside shell 10 and exchange heat with the external world
There is condensation after avoiding 10 outer surface of shell from being influenced cooling by internal temperature in amount.And, it is assumed that refrigerant phase transformation absorbs amount of heat
When to the first 11 sub-cooled of accommodating chamber, because the first accommodating chamber 11 is closed chamber, flowed into the first accommodating chamber 11 without new air,
Radiator 32 and 50 surface of the first electric appliance mould group are not in lasting dew condensation phenomenon, and a period of time is persistently subcooled in radiator 32
Afterwards, it further reduced the temperature of air in the first accommodating chamber 11, and the temperature of air and radiator 32 in the first accommodating chamber 11
The temperature difference of surface temperature gradually decreases, and dew condensation phenomenon will disappear.
Further, shell 10 includes inner casing 12, shell 14 and heat-barrier material 16, and inner casing 12 and the interval of shell 14 are arranged,
Heat-barrier material 16 is filled between shell 14 and inner casing 12, is prevented 12 internal environment of inner casing with the external world and is exchanged heat.Optionally, every
Hot material 16 is the blown rubber filled using foam process.Specifically, there is accommodating chamber in inner casing 12, is arranged in inner casing 12
Accommodating chamber is divided into the first accommodating chamber 11 and the second accommodating chamber 13 by partition.
In above-mentioned inverter 100, the first different electric appliance mould group 50 of calorific value and the second electric appliance mould group 90 are respectively set
It is individually right by refrigerant cooling component 30 and cooling by water component 70 in the first accommodating chamber 11 and the second accommodating chamber 13, and respectively
The two is cooled down.The first electric appliance mould group 50 higher for calorific value, can provide lower cooling temperature using refrigerant, can
So that the temperature of the first electric appliance mould group 50 is reduced within the scope of reasonable temperature, the first electric appliance mould group 50 is available effectively cold
But.The second electric appliance mould group 90 less for calorific value, the cooling temperature generated using cooling water is higher, will not be to the second electric appliance
Mould group 90 generates supercooling, avoid the second electric appliance mould group 90 because cooling temperature is too low and there is condensation in surface, guarantee electronic device
Safety.So guarantee cooling effect, while electronic device surface being avoided condensation occur.
