Freezing type drier anhydrates minute by reducing compressed-air actuated temperature, analysing, and then compressed air is heated near original temperature.Traditional freezing type drier is the split-type structural with fan, and with two heat exchangers, power consumption is larger, and operating efficiency is lower.Simultaneously, use two heat exchangers, volume is large, and cost is high, safeguards inconvenience.
The utility model content
Based on this, being necessary provides the second heat exchange integral machine that is used for freezing type drier that a kind of power consumption is lower, operating efficiency is higher for the problem that traditional split-type structural freezing type drier power consumption is large, efficient is lower.
A kind of second heat exchange integral machine comprises heat exchanger and secondary heat exchanger, and described secondary heat exchanger is installed in heat exchanger, and described secondary heat exchanger comprises heat pipe and fin, and described fin is sheathed on described heat pipe.
In a preferred embodiment, a described heat exchanger comprises heat exchanger tube and support, described heat exchanger tube is installed on support, described heat exchanger middle part is provided with cavity, the one end sealing of described cavity, described secondary heat exchanger is installed in the described cavity by the other end of a described heat exchanger.
In a preferred embodiment, the surface of described heat exchanger tube structure in the shape of a spiral.
In a preferred embodiment, a described heat exchanger also comprises blade, and described blade axially arranges along described heat exchanger tube.
In a preferred embodiment, also comprise shell, described casing is located at a described heat exchanger, and described shell is provided with air inlet and gas outlet.
Above-mentioned second heat exchange integral machine, compressed air at first carries out heat exchange through a heat exchanger, then enter that cold medium carries out heat exchange in secondary heat exchanger and the heat pipe, reduce compressed-air actuated temperature, condensate moisture in the compressed air, in to compressed-air actuated dry run, power consumption is lower, and efficient is higher.

Fig. 2 is the stereogram of secondary heat exchanger among Fig. 1;
Fig. 3 is the stereogram of a heat exchanger among Fig. 2.
The specific embodiment
In order to solve the problem that traditional split-type structural freezing type drier power consumption is large, efficient is lower, provide the second heat exchange integral machine that is used for freezing type drier that a kind of power consumption is lower, operating efficiency is higher.
Such as Fig. 1, Fig. 2 and shown in Figure 3, the second heat exchange integral machine of an embodiment comprises heat exchanger 120 and secondary heat exchanger 110.Secondary heat exchanger 110 is installed in heat exchanger 120, and secondary heat exchanger 110 comprises heat pipe 112 and fin 114, and fin 114 is sheathed on heat pipe 112.Heat pipe 112 is used for passing into cold medium, and fin 114 can increase the compressed air resistance that flows and the contact area that increases heat exchange.
Above-mentioned second heat exchange integral machine, compressed air at first carries out heat exchange through a heat exchanger 120, then enter that cold medium carries out heat exchange in secondary heat exchanger 110 and the heat pipe 112, reduce compressed-air actuated temperature, condensate moisture in the compressed air, in to compressed-air actuated dry run, power consumption is lower, and efficient is higher.
In the present embodiment, a heat exchanger 120 comprises heat exchanger tube 122 and support 124.Heat exchanger tube 122 is installed on support 124.No. one time heat exchanger 120 middle parts are provided with cavity 126, the end sealing of cavity, and secondary heat exchanger 110 is installed in the cavity 126 by the other end of a heat exchanger 120.Usually, secondary heat exchanger 110 is packed into behind heat exchanger 120, sealed at both ends, leak to prevent compressed air.
In the present embodiment, the surface of heat exchanger tube 122 is structure in the shape of a spiral, to increase the contact area of heat exchange.No. one time heat exchanger 120 also comprises blade 128, and blade 124 axially arranges along heat exchanger tube 122.The setting of blade can be that compressed air enters heat exchanger 120 and flows towards a plurality of directions when flowing in a heat exchanger 120.
Usually, the second heat exchange integral machine also comprises shell 130.Shell 130 is sheathed on heat exchanger 120 No. one time, and shell 130 is provided with air inlet and gas outlet.
Above-mentioned second heat exchange integral machine, employed two heat exchangers of relatively traditional freezing type drier, power consumption is lower, efficient is higher, and simultaneously, small volume has reduced cost and maintenance cost.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
