Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Central air-conditioning single system dry evaporator, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5；Institute Shell 1 is stated as cylindrical shell, is provided with water inlet 11, water outlet 12, gas vent 13 and osculum 14；The water inlet 11 by Flanged joint is in water inlet pipe, and the water outlet 12 is by flanged joint in outlet pipe, and the gas vent 13 is welded with casing, the casing Air bleeding valve is installed again；The osculum 14 is welded with casing, which installs air bleeding valve again；Shell 1 occupies entire evaporator All spaces, therefore pre-set water and the intake-outlet of medium on shell 1 and can save big quantity space, optimize host Design；Water inlet 11 and water outlet 12 are easy for installation using flanged joint, easy Maintenance and Repair；Gas vent and osculum 14 Frequency of use is not high, and failure rate is very low, so can reduce leakage using welding method.The copper pipe 2 is by the drive end bearing bracket 3 Lower half enters in the shell 1, is turned back again to the drive end bearing bracket 3 in the rear end that the shell 1 is extended in the shell 1 The first half；The internal face and outside wall surface of the copper pipe 2 are screwed surface；The inside and outside wall surface of copper pipe 2 is all screw thread table Face can enhance heat exchange area, so as to improve heat exchange efficiency, reduce energy consumption；The excircle of the drive end bearing bracket 3 is connected to described outer The front end of shell 1, the drive end bearing bracket 3 are provided with medium inlet 31 and media outlet 32, and the medium inlet 31 is located at lower half, institute It states media outlet 32 and is located at the first half；The middle of the inside of the drive end bearing bracket 3 is provided with lagging, and the lagging is by described in The inner space of drive end bearing bracket 3 is divided into the first half and lower half；The first half is the concentration of the medium inlet of the copper pipe 2 Portion, the lower half are in the middle part of the collection of the media outlet of the copper pipe 2；Medium enters also from drive end bearing bracket 3 to go out from drive end bearing bracket 3 It goes, homonymy so that installation manufactures and maintenance is all more easy into the structure that homonymy goes out, and the evaporation that can increase medium is grown Degree has the heat exchange distance of twice of 1 length of shell in the length of a shell 1；
