Evaporator

Abstract

The invention provides an evaporator. A main body structure is connected with an outer barrel through an inner barrel; the outer barrel is a thin plate piece and is provided with at least one spiral groove; the outer barrel is connected with a flow equalizing plate and the inner barrel to form a flow channel; an input cavity and an output cavity are arranged at two ends of the flow channel and are respectively provided with a connector; a turbulent groove is formed in the flow channel, the flow equalizing plate is provided with flow equalizing holes, and the inner surface of the inner barrel is provided with shallow narrow grooves; during ice making, a low-temperature and low-pressure liquid refrigerant is continuously input through an input port, enters the flow channel through the flow equalizing holes, is turbulent in the turbulent flow groove, exchanges heat with water uniformly flowing through the inner surface of the inner barrel through the inner barrel, absorbs heat and evaporates to form low-temperature and low-pressure gas, and then is output through an output port, and the water is cooled to gradually make tangible ice; and refrigerant and water can achieve heat exchange only by being separated by one layer of plate, refrigerant turbulence is achieved through a turbulence section, fluid concurrent flow can be avoided, the heat exchange efficiency of the ice maker is improved, the ice making efficiency of the evaporator is greatly improved, and the evaporator is more energy-saving, economical and practical.

Description

technical field [0001] The invention relates to the technical field of ice making machines, in particular to an evaporator of the ice making machine. Background technique [0002] At present, the ice machine evaporator used in the current ice machine has a simple structure, low production efficiency, and low heat exchange efficiency. There are multi-turn copper tubes with a set length on the outer plate of the evaporator cylinder, and then the contact is ensured by soldering. Welding is difficult and easy to weld, and because of uneven solder flow, it is easy to cause poor heat transfer, uneven shape of ice cubes, and even damage to the compressor due to liquid shock. Figure 9 shown. [0003] The ice making efficiency of the evaporator of the ice machine under the prior art is poor, the compressor of the ice machine is seriously damaged, the maintenance volume in the market is large, and the general energy consumption is relatively large, which needs to be improved urgently...
