The box-shaped shell-and-tube heat exchanger is characterized in that the shell is a rectangular box type shell, the two ends of the inside of the shell are respectively provided with a front-end header and a rear-end header, the front-end header is arranged between a front rectangular tube plate and a front-end header cover, and the rear-end header is arranged between a rear rectangular tube plate and a rear-end header cover. The heat exchange tube bundle with tubes arranged in a square shape is fixed on the tube plates, the two sides of rectangular tube plates are respectively provided with a pass partition plate, pass partition plates of the two sides of the same tube plate are in a straight line, the tube side heat medium inlet and the tube side heat medium outlet are arranged on the upper side and the lower side of the front-end header, and the shell side heat medium inlet and the shell side heat medium outlet are positioned on the upper side and the lower side of the box type shell close to one end of the front-end header. The box-shaped shell-and-tube heat exchanger adopts a rectangular box type structure, and is simple in structure, even in shell side pass, convenient in fabrication and low in cost, thereby being an efficient and energy-saving heat exchange device.
Description
Technical field
The utility model belongs to the not direct heat-exchange apparatus of contact of heat exchange medium, especially for the heat-exchange device of the fixed pipe channels assembly of two kinds of heat exchange mediums.
Background technology
The low temperature difference does not have the heat transmission equipment that heat exchange between phase-change liquid is mainly used in water source heat pump system, it mainly extracts the purpose that heat reaches refrigeration and heat supply by heat exchange between intermediary's water of all kinds of water sources medium and evaporator of refrigerator, and the temperature difference generally has only about 2 ℃～3 ℃; Also have relatively poor profit of thermal conductivity and the heat exchange between oil and the oil.Currently used heat transmission equipment form is mainly traditional many cascaded structures of shell-and-tube fixed tube-sheet exchanger and satisfies temperature difference heat exchange requirement.As adopt the then necessary structure that adopts multipaths of separate unit, shell-side multipaths to be difficult to realize then that it also will improve greatly to designing, make, install the cost of all making troubles with traditional shell-and-tube heat exchanger structure.The heat exchange of not having between phase-change liquid with the satisfied low temperature difference of the traditional shell-and-tube fixed tube-sheet exchanger of separate unit never has suitable heat transmission equipment for this reason.Adopt traditional many series connection of shell-and-tube fixed tube-sheet exchanger just to exist: number of devices is many, the heat exchange effect is relatively poor, fluid resistance is big, shell-side inlet place stringing need be reserved enough circulation areas and prevent that flow velocity is too high and wash out tube bank, causes many deficiencies such as the device structure volume is big, equipment cost height.
The utility model content
In order to overcome the deficiency that existing shell-and-tube heat exchanger is not easy to realize multipaths, the utility model provides a kind of box-shaped shell-and-tube heat exchanger, this box-shaped shell-and-tube heat exchanger not only can be realized the design of the pure adverse current of multipaths, and can improve the heat exchange effect between no phase-change liquid.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of box-shaped shell-and-tube heat exchanger, comprise housing, tube sheet, heat-exchanging tube bundle, the shell side heating agent is imported and exported, the tube side heating agent is imported and exported, it is characterized in that: described housing is the box-type shell of cuboid, front end collection case before two ends are respectively in the housing between rectangle tube sheet and the front end collection case lid, rear end collection case between back rectangle tube sheet and the rear end collection case lid, the heat-exchanging tube bundle that is square stringing is fixed on the tube sheet, rectangle tube sheet both sides are equipped with branch journey baffle plate respectively, what be positioned at two sections collection casees is pipe side branch journey baffle plate, what be positioned at box-type shell is shell-side branch journey baffle plate, the branch journey baffle plate of same tube sheet both sides point-blank, the tube side heating agent is imported and exported and is located at front end collection case both sides up and down, and the shell side heating agent is imported and exported and is located at the up and down both sides of box-type shell near front end collection case one end.
Described shell side heating agent is imported and exported and is the special-shaped liquid entrance of flared type, and import department is provided with buffer board.
At least four roads rod baffle group vertical with tube bank is housed in the described box-type shell, and described rod baffle group is made up of the rod baffle of horizontal setting and the rod baffle of vertically settling.
Shell-side branch journey baffle plate end before being installed in the journey baffle plate in described minute on the rectangle tube sheet and back rectangle tube sheet retention gap are installed in the terminal and preceding rectangle tube sheet retention gap of shell-side branch journey baffle plate on the rectangle tube sheet of back; The branch journey baffle plate of rectangle tube sheet both sides is arranged with the branch journey baffle interval that is installed in preceding rectangle tube sheet both sides before being installed in.
Adopt bolt to be connected between described box-type shell two ends and the front and back end collection case lid.
The beneficial effects of the utility model are: owing to adopt the pure counter-flow designs of multipaths to have good effect of heat exchange, low temperature difference heat exchange can be realized in no slough; Because the shell-side tube bundle support adopts the deflection bar type supporting construction to make it have the little characteristics of good effect of heat exchange fluid resistance; Because the circulation area that shell-side adopts the erosion control form of the special-shaped import and export mix of flared type and multiaperture-type to increase import has reduced the liquid entrance flow velocity greatly and has avoided in the direct impact of import and export to tube bank; Owing to adopted the box structure and the foursquare stringing mode of rectangle tube sheet, made the stringing number maximization on the unit are; Because front and back end collection case lid is connected with the tank ends bolt and can opens bobbin carriage and make the maintenance of equipment very convenient; Owing to adopt the case structure of rectangle, the structure of equipment is simpler, the branch journey of shell side is evenly succinct, manufacturings is convenient and floor space is little, cost is low, and compare the saving cost with the conventional tube shell heat exchanger about about 40%, is a kind of energy-saving heat-exchange equipment efficiently.
