Description
Technical field
The present invention relates to technical field of central air more particularly to shell to concatenate shell-tube type double space plate refrigerated heat exchanger.
Background technique
Evaporator and condenser in refrigeration system are all a kind of concrete forms of heat exchanger, in central air-conditioning industry,
The form of evaporator is more varied, including the diversified forms such as shell-and-tube, board-like.Shell-and-tube applies in general to prepare cold water
Air-cooled unit.In national most of region, different calendar variations causes refrigerating capacity different, such as the refrigeration peak of summer
When need to put into high gear to freeze, but refrigeration demands less season does not need full-amount inrush then in winter etc..Mesh
It is preceding also to have converter technique that solve the problems, such as that refrigerating capacity changes in a certain range, but excessive refrigerating capacity is changed
It is in fact helpless.The cooling capacity that separate unit water cooler is capable of providing is limited, and is run together by more water coolers to improve
Refrigerating capacity, respective refrigeration system still independent operating are not interfere with each other, and stop several systems when refrigeration capacity requirement is reduced
Cooling system.But the problem of arrangement of multiple refrigeration systems will lead to space utilization rate, condenser are mounted on outdoor general still solution
Certainly, but as evaporator it is necessarily mounted at interior, and the space for accommodating evaporator is limited, it is necessary to consider that multiple refrigeration systems
The installation space problem of the evaporator of system.

It is welded, is provided with gasket between the rear end cap and rear bulkhead；Water is formed between the cylindrical shell, bottom cover and rear bulkhead
Chamber；
The outer ring sealing welding of one end face of the rear bulkhead in the outer ring of the second end of the shell, the rear bulkhead it is another
The outer ring of end face offers annular groove, and the annular groove accommodates the outer ring of the rear end cap；
The copper pipe is in the interior of shell, for through the first end, second end, front baffle, spacing board of the entire shell
With the whole root canal of rear bulkhead.
The present invention shares the water route of the evaporator of multiple refrigeration systems, and refrigerant line is then in each individual shell
It is interior, reduce space hold；Because the evaporator is film covering type (being covered on the outer inner surface of copper pipe when coolant liquid), make to freeze
Agent import is located at position more on the lower, then can gradually go up liquid level when refrigerant enters, and first exchange heat with the water inlet water pipe compared with low temperature；
After increasing to certain altitude, refrigerant exchanges heat after temperature is higher, then with the return water temperature of higher temperatures；It therefore can be sufficiently sharp
It is exchanged heat with the water in copper pipe, improves heat exchange efficiency.
