Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, in the embodiment of the utility model, an air conditioner evaporator includes a fixed plate 1, a fixed table 4, a coil 13 and a magnetic separation box 10, and the coil 13 is provided with a plurality of parallel fins 8 , the fixed plate 1 is installed on both ends of the coil 13, the fixed table 4 is installed on the top of the fixed plate 1, the coil 13 is provided with a pre-cooling pipeline 3 between the fixed plates 1, and the pre-cooling pipeline 3 is arranged on the coil On the lowermost pipeline of the pipe 13, expansion joints 5 are provided at both ends of the pre-cooling pipeline 3. The expansion joints 5 provided can effectively prevent the expansion and contraction of the pre-cooling pipeline 3 due to excessive temperature difference, and avoid damage to the pipeline; The left end of the coil 13 is connected to the main pipeline 2 located outside the fixed plate 1 through the flange 9. The connection through the flange 9 facilitates the installation and disassembly of the main pipeline 2, thereby facilitating the maintenance and repair of the evaporator. The role of the cold pipeline 3 is to reduce the water vapor content of the air in the main pipeline 2 of the evaporator, thereby reducing the amount of frost on the coil 13 and improving the heat exchange efficiency of the coil 13; the end of the main pipeline 2 is connected to a fixed 1 above the inclined buffer tank 11, the inclination angle of the buffer tank 11 is 45°, the buffer tank 11 is provided with a buffer pipe 12 communicating with the main pipeline 2, the length of the buffer pipe 12 is half of the length of the buffer tank 12, and the set The buffer tank 12 can effectively reduce the impact of air and liquid on the coil 13 and increase the life of the evaporator; the buffer tank 11 is connected to the magnetic separation box 10 fixed on the top of the fixed table 4 through the elbow 14, and the magnetic separation box 10 is connected with a The liquid pipe 6 and the right end of the coil pipe 13 are connected to the liquid outlet pipe 7 located outside the fixed plate 1 through the flange 9, and the air or liquid entering the coil pipe 13 is first filtered through the action of the magnetic separation box 10 to remove the magnetism therein.
