Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
Heat pump unit dual system shell 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；11 He of water inlet
Water outlet 12 is arranged in the middle part of the same side of the shell 1 and positioned at same horizontal line, and is located at the shell 1 respectively
The farthest position in front-end and back-end；The gas vent 13 is located at the top of the shell 1, and the osculum 14 is located at described outer
The bottom of shell 1；Shell 1 occupies all spaces of entire evaporator, therefore the disengaging of water and medium is pre-set on shell 1
The mouth of a river can save big quantity space, optimize the design of host；The water inlet 11 and water outlet 12 are arranged at evaporator shell 1
Side, be easier maintenance, disengaging host facilitated to carry out trouble shooting and installation.The copper pipe 2 is by the drive end bearing bracket 3
Lower half into the shell 1, turned back again to the drive end bearing bracket 3 in the rear end that the shell 1 is extended in the shell 1
