Evaporator for cooling water machine

Abstract

The invention relates to the technical field of cooling water machines, particularly to an evaporator for a cooling water machine. The evaporator for the cooling water machine is characterized by comprising a square water tank with a top opening, at least two rows of copper tubes are arranged inside the water tank, every row of copper tubes are composed of at least two copper tubes, the copper tubes inside the water tank are positioned through at least two acrylic boards and connected in series through welding elbows, and both ends of every copper tube are connected with refrigerant above the water tank; the wall of the water tank is provided with a water outlet, the water outlet is connected with a water inlet pipe above the tank after passing through a water guide pipe and an external device, and the water guide pipe is provided with a water pump. The evaporator for the cooling water machine has the advantages of saving the space and reducing the integral structure appearance, reducing the flowing distance of water and achieving good heat exchange effects by being in direct contact with water, effectively blocking water flow through the acrylic boards inside the water tank to fully exchange heat, reducing the production cost and the like.

Description

technical field [0001] The invention relates to the technical field of water chillers, in particular to an evaporator for chillers with small volume and good heat exchange effect. Background technique [0002] As we all know, chillers are widely used. The evaporator is an important part of the chiller. The existing chiller evaporator is provided with a closed shell, and the shell is equipped with an evaporation (refrigerant) copper tube, and the copper tube is inside the shell. It is in the shape of a spiral disk, and the two ends of the copper tube extend out of the shell through the copper tube holes on the shell and are connected with the refrigerant source. The closed shell is also provided with a water inlet and a water outlet. The nozzles are respectively connected to the water source through the catheter tube, and the two ends of the copper tube are respectively connected to the refrigerant through the catheter tube. The refrigerant in the copper tube exchanges heat w...

[0002] As we all know, chillers are widely used. The evaporator is an important part of the chiller. The existing chiller evaporator is provided with a closed shell, and the shell is equipped with an evaporation (refrigerant) copper tube, and the copper tube is inside the shell. It is in the shape of a spiral disk, and the two ends of the copper tube extend out of the shell through the copper tube holes on the shell and are connected with the refrigerant source. The closed shell is also provided with a water inlet and a water outlet. The nozzles are respectively connected to the water source through the catheter tube, and the two ends of the copper tube are respectively connected to the refrigerant through the catheter tube. The refrigerant in the copper tube exchanges heat with the natural water in the shell. The disadvantage is that it takes up a lot of space. The overall appearance of the machine is larger; second, the heat exchange efficiency is low, and natural water needs to be continuously circulated in the shell to generate heat energy; third, it is difficult to repair and maintain
