Multi-shell-section copper-tube-shared single-spacing-plate cold water heat exchanger

Abstract

A multi-shell-section copper-tube-shared single-spacing-plate cold water heat exchanger comprises multiple shells, a front end cover, a front partition plate, spacing plates, a back end cover, a backpartition plate and a copper tube. Each shell is a cylindrical cast iron shell. The multiple shells are connected in series in an end-to-end manner and sealed. Each shell is used as a shell of an evaporator of a refrigeration system. Each shell is provided with a refrigerant inlet, a refrigerant outlet, an exhaust opening and an oil discharging opening. The edges of a base shell and a tube shell of the front end cover are provided with bolt holes. The two ends of each spacing plate are welded to the ends of the two corresponding shells correspondingly. A water cavity is formed between the backend cover and the back partition plate. The back partition plate is provided with a ring groove. According to the multi-shell-section copper-tube-shared single-spacing-plate cold water heat exchanger, the evaporators in the multiple refrigeration systems share the water channel, occupied space is reduced, and it is guaranteed that operation is conducted under stable working conditions at any timeaccording to actual operation working conditions.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a cold water heat exchanger with multiple shell copper tubes sharing a single partition plate. Background technique [0002] Both the evaporator and condenser in the refrigeration system are a specific form of heat exchanger. In the central air-conditioning industry, the evaporator has a variety of forms, including shell-and-tube, plate and other forms. The shell-and-tube type is generally suitable for air-cooled units that prepare cold water. In most regions of the country, different seasonal differences lead to different cooling capacity. For example, during the peak cooling time in summer, full power is required for cooling, but in winter and other seasons when cooling demand is low, full power is not required. At present, there is also frequency conversion technology that can solve the problem of cooling capacity changes within a certain range, but it is pow...

AI Technical Summary

Problems solved by technology

However, the arrangement of multiple refrigeration systems will lead to the problem of space utilization. Generally, the condenser can be installed outdoors, but as an evaporator, it must be installed indoors, and the space for the evaporator is limited. Multiple refrigeration systems must be considered. The installation space of the evaporator of the system
