Abstract

The invention discloses a horizontal type plate heat exchange mixed flow evaporator. The shape of a plate piece inside the evaporator is characterized in that the two ends of the plate piece are triangular, and the middle of the inner plate piece is rectangular; and the outer part of the evaporator is composed of the plate piece, an upper left semicircular box, a lower left semicircular box, an upper right semicircular box, a lower right semicircular box, a spraying pipe, a flow equalizing plate and a cold-hot fluid inlet-outlet port. By adopting the horizontal type plate heat exchange mixed flow evaporator, the problem that oil return of a compressor is difficult due to the fact that freon is used as a refrigerant is solved; the refrigerating efficiency of a refrigerating machine is improved, and the effect is more obvious under the low-temperature working condition; and therefore, the requirements for the large temperature difference required by certain production processes are met.

Description

Technical field: [0001] The invention relates to the field of refrigeration evaporators. It is a horizontal plate exchange mixed-flow evaporator. Its structure solves the problem that Freon is used as a refrigerant and it is difficult to return oil from a compressor; the refrigeration efficiency of a refrigerator is improved, and the effect is more effective under low temperature conditions. Significant; meet the requirements of large temperature difference required by some production processes. Background technique: [0002] Most of the current evaporators use dry evaporators and flooded evaporators. Among them, the oil return problem of the dry evaporator compressor can be solved, and it can also meet low temperature conditions, but its refrigeration efficiency is low; while the flooded evaporator The cooling efficiency of the compressor is high, but it is difficult for the compressor to return oil, which affects the cooling effect and cannot meet the low temperature condi...
