Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Water cooler single system dry type heat exchanger, including shell 1, copper pipe 2, drive end bearing bracket 3, rear end cap 4 and spoiler 5；Institute
Stating shell 1 is cylindrical shell, is provided with water inlet 11, water outlet 12, gas vent 13 and drainage hole 14；The water inlet 11 by
It is threadedly connected to water inlet pipe, the water outlet 12 is threaded with casing by being threadedly connected to outlet pipe, the gas vent 13, should
Casing installs exhaust valve again；The drainage hole 14 is threaded with casing, which installs exhaust valve again；Shell 1 occupies whole
All spaces of a evaporator, therefore preset water and the intake-outlet of medium on shell 1 and can save big quantity space, it is excellent
The design of host is changed；Water inlet 11, water outlet 12, gas vent and drainage hole 14 are all made of threaded connection, easy for installation, and
And it is easy Maintenance and Repair；Failure rate is lower for flanged joint.The copper pipe 2 by the drive end bearing bracket 3 lower half into
