Shell type heat exchanger, water cooling add-on module, and water cooling system

Abstract

The present invention discloses a shell type heat exchanger, a water cooling add-on module, and a water cooling system, wherein the shell type heat exchanger comprises a vertical shell and a pipe coil evaporator. A water inlet is formed in a top end of a side face of the vertical shell, while a water outlet is formed in a bottom end of the side face; an air exhausting opening is formed in a top face of the vertical shell, while a sewage draining opening is formed in a bottom face thereof; and an automatic air exhausting cover is mounted on the air exhausting opening. The pipe coil evaporator comprises a coolant inlet pipe, a vertical pipe, a spiral coil pipe and a coolant outlet pipe that are connected in sequence. The vertical pipe and the spiral coil pipe are arranged inside the vertical shell. A bottom end of the vertical pipe extends to the bottom face of the vertical shell to be connected with the coolant inlet pipe, while a top end of the vertical pipe is close to an inner wall of the top face of the vertical shell and connected with a top end of the spiral coil pipe, and a bottom end of the spiral coil pipe extends to the bottom face of the vertical shell to be connected with the coolant outlet pipe. The spiral coil pipe is spirally coiled with the vertical pipe as a center. A coolant fed into the coolant inlet pipe is opposite to a heat source fed into the water inlet in direction. The shell type heat exchanger is capable of realizing high-efficiency constant-temperature cooling, convenient for fast assembly, and particularly suitable for add-on type installation.

Description

technical field [0001] The invention relates to a cooling device, in particular to a shell-type heat exchanger, a water-cooling external module and a water-cooling system, belonging to the technical field of water-cooling devices. Background technique [0002] A heat exchanger is a heat exchange device that transfers part of the heat of the hot fluid to the cold fluid so that the temperature of the fluid reaches the index specified in the process, also known as a heat exchanger. Heat exchangers are widely used as heat transfer equipment. With the rapid development of energy-saving technology, there are more and more types of heat exchangers, and shell heat exchangers are one of them. [0003] With the continuous development of the new energy industry, electric vehicles are occupying more and more market advantages due to their energy-saving and environmental protection features. As one of the core components of electric vehicles, power batteries have higher requirements for ...

AI Technical Summary

Problems solved by technology

[0005] Shell-type heat exchangers are widely used in water-cooled cooling devices. However, the existing shell-type heat exchangers have complex structures and twists and turns in the pipeline layout in the shell. Not only the equipment cost is high, but also the heat exchange effect is not good. , and the uneven speed of the thermal fluid in the shell, resulting in poor heat transfer temperature stability, which affects the heat dissipation effect of the power battery
