Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a tinned copper fin evaporator comprises a shell 2, a fixed rod 3 is arranged inside the shell 2, an installation base 5 is arranged below the fixed rod 3, two fixed plates 1 are arranged above the installation base 5, the tops of the two fixed plates 1 are fixedly connected with the fixed rod 3, three coil pipes 9 are respectively connected between the two fixed plates 1, the three coil pipes 9 are symmetrically, equidistantly and vertically distributed, connectors 4 are connected between the three coil pipes 9, the number of the connectors 4 is two, fins 10 are arranged outside the coil pipes 9, the fins 10 are made of galvanized copper materials, resistance wires 8 are arranged outside the three coil pipes 9, the three resistance wires 8 penetrate through the fins 10, the traditional defrosting mode is generally reverse circulation ring defrosting, namely, the electromagnetic directional valve is switched to be switched on and off to achieve the defrosting effect through contacts of a defrosting controller switch, a unit frequently enters a defrosting program, cause the temperature undulant big, reduce the bearing capacity on frost layer, be unfavorable for user's use, this practicality uses outside resistance wire 8 to heat the defrosting, has avoided the undulant big phenomenon of temperature that the unit inside was adjusted and is caused.

Furthermore, a plurality of fins 10 are arranged, the plurality of fins 10 are symmetrically and equidistantly horizontally distributed, and the fins 10 serve to increase the surface area of the coil 9 so as to increase the heat transfer area for better refrigeration.
