The equipment investment is less, the maintenance cost is low, all investment can be recovered within two to three years, and the cost performance is good.
Preferably, a secondary refrigerant throttle expansion valve 31 and a secondary air conditioning compressor 32 are disposed at the secondary air-cooled evaporator 30, and a circulating cooling water pump 92, a cooling water inlet valve 93, a drain valve 94 and a cooling water outlet valve 95 are disposed on a loop of the primary air-cooled evaporator 20 and the spray cooling evaporator 50. Whole device compact structure, novel structure, design benefit, the suitability is strong, the facilitate promotion.
Referring to fig. 8, a structural diagram of an embodiment integrally configured with a heat sink is shown, which is different from the first embodiment: a re-cooling source is provided. Referring to fig. 9, a structure diagram of an embodiment of a split type cooling device is shown, which is different from the embodiment: the device is provided with a re-cooling source and adopts a split type, and the split structures are connected by an external connecting pipe.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
