Description
Technical field
The present invention relates to technical field of central air more particularly to shell concatenation copper pipe to share separate room partition plate refrigeration evaporator
Device.
Background technology
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 full-amount inrush is then not required in refrigeration demands less season in winter etc..Mesh
It is preceding also to have converter technique that solve the problems, such as that refrigerating capacity changes in certain scope, but change for excessive refrigerating capacity
It is in fact helpless.The cold that separate unit handpiece Water Chilling Units are capable of providing is limited, runs to improve together by more handpiece Water Chilling Units
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 arrangement of multiple refrigeration systems can cause the problem of space availability ratio, condenser general still solution installed outdoors
Certainly, but as evaporator interior is necessarily mounted at, 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.
The content of the invention
It is an object of the invention to propose that a kind of shell concatenation copper pipe shares separate room partition plate refrigerating evaporator.

It exports separate；
The drive end bearing bracket is buckled in the front baffle；The drive end bearing bracket be casting integrated shaping, including bottom case, outer rim, shell and into
Water outlet partition plate, the shell are raised in the bottom case, water inlet, water outlet are offered on the shell；The Inlet and outlet water partition plate
The left and right of the bottom shell is traversed, is two parts of intake antrum and water chamber by the inside division of the drive end bearing bracket；Described
The edge of bottom case has several bolts hole, offers several bolts hole again at the edge of the shell, these bolts hole
For connected with outer casing；
The outer ring sealing welding of the front baffle exceeds the outer of the shell with shape in the outer ring of the first end of the shell
It is bolted into the space of a certain number of bolts hole, and with the drive end bearing bracket；The front baffle offers perforative for holding
Receive the hole of copper pipe, the copper pipe forms sealing with expansion tube process through the hole；The horizontal level at the middle part of the front baffle is not opened
If for accommodating the hole of copper pipe, which is equipped with gasket corresponding with the Inlet and outlet water partition position；
The spacing board is made of cast iron Q235；It offers the circular hole of the position of the corresponding copper pipe, is passed through for the copper pipe,
And it will be sealed after the copper pipe tube expansion with the spacing board；The both ends of the spacing board are respectively welded in the end of two sections of shells；
The edge of the spacing board offers trapezoidal welding step, and welding step is used to accept the shell of left and right ends, two steps
Centre is the protrusion around the edge of the spacing board, which protrudes from the shell；
The rear end cap is bolted on the rear bulkhead；The rear end cap is by the cylindrical shell of outer ring and the bottom cover of spherical
It is welded, gasket is provided 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 the rear bulkhead is set in the outer ring of the second end of the shell between the rear end cap and rear bulkhead
Put washer sealing；
The copper pipe is through the first end of the entire shell, second end, front baffle, spacing board in the enclosure
With whole pipe 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（The outer inner surface of copper pipe is covered in during coolant liquid）, make refrigeration
Agent import is located at position more on the lower, then refrigerant first exchanges heat into the fashionable liquid level that can gradually go up 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 fully sharp
It is exchanged heat with the water in copper pipe, improves heat exchange efficiency.
