Abstract
The utility model discloses a volume-type heat exchanger, which belongs to a device for exchanging heat between hot fluid and cold fluid. The utility model is characterized in that a heat exchanger of a corrugated tube shell type is inserted into a water storage tank, and the front and the back tube boxes of the heat exchanger of a corrugated tube shell type are exposed; the connecting point of a heating medium inlet tube and a tube shell is welded with a knife-type ribbed plate; the bottom of the ribbed plate is fixed with an arc-shaped (or square) baffle plate. Compared with a traditional volume-type heat exchanger, the heat transfer coefficient of the utility model is four times higher, and a steam trap is not needed being arranged. Thus the utility model has the advantages of energy saving, simple assembly and convenient tube change, and is suitable for the hot water supply system of industries and civil buildings, and is especially suitable for the hot water supply system of the high-rise buildings.
Description
The utility model belongs to the device of exchange heat between a kind of cold and hot two kinds of fluids, particularly a kind of volumetric heat exchanger.
In the prior art volumetric heat exchanger water storage simplified be the working space of heated medium, tube side is the heat medium working space, and directly insert water storage simplified in.Therefore, the heat transferring medium flow velocity is slow, and the thermal efficiency is low.Adopt U type heat exchange of heat pipe to insert the method for water storing tank, can accelerate velocity of medium, reduction equipment volume, making its shell side is the working space of heat medium, tube side is the working space of heated medium, small product size is little, and the heat exchange amount is big, the complex heat transfer coefficient height, but assembling is complicated, changes the heat exchanger tube inconvenience of damaging.
The purpose of this utility model just provides a kind of volumetric heat exchanger simple, compact conformation of assembling.
The purpose of this utility model is achieved in that a kind of volumetric heat exchanger, comprise water storing tank, the bellows tube shell-and-tube heat exchanger, the bellows tube shell-and-tube heat exchanger comprises vessel flange, baffle plate, internal fixation at heat exchanger has deflection plate, pass partition, tube sheet is fixed on the housing, the node heat exchanger tube is fixed on the tube sheet, it is characterized in that: the bellows tube shell-and-tube heat exchanger inserts water storing tank, and expose bobbin carriage before and after it, on the front header of heat exchanger, be provided with domestic water import c and outlet b, be provided with heat medium import a and outlet d on housing, at heat medium inlet tube and housing joint welding kitchen knife formula gusset, the gusset bottom is curved baffle fixedly.
The utility model also can be fixed adapter in the heat medium inlet tube, welding lacing wire in taking over, the foraminate dished disk of lacing wire bottom fixed band.
Advantage of the present utility model is: when adopting steam to be heat medium, domestic water is walked tube side; When heat medium was liquid, domestic water was walked shell side, was directly entered in the water storing tank by the shell side opening, thereby compared with traditional volumetric heat exchanger, and its heat transfer coefficient exceeds three times of the latter, need not adorn steam trap, so energy-saving effect is obvious.Owing to adopt the curved tailgate structure of kitchen knife formula gusset and the narrow meshed dished disk in the reallocation buffer structure, guaranteed rational assemble sequence, the disadvantage of having avoided the soldered splash of node heat exchanger tube to scald, and it is convenient to change the heat exchanger tube that damages.The utility model is applicable to industry and civil buildings hot water supply system, is specially adapted to the hot water supply system of high-rise.
Fig. 1 is the utility model structural representation.
Fig. 2 is the baffle arrangement schematic diagram.
Fig. 3 is the dished disk structural representation.
Below in conjunction with accompanying drawing the utility model is described in further details.
The utility model comprises water storing tank 1, bellows tube shell-and-tube heat exchanger 2, bellows tube shell-and-tube heat exchanger 2 comprises vessel flange 4, baffle plate 8, internal fixation at heat exchanger has deflection plate 5, pass partition 6, tube sheet 3 is fixed on the housing, node heat exchanger tube 7 is fixed on the tube sheet 3, bellows tube shell-and-tube heat exchanger 2 inserts in the water storing tank 1, and expose bobbin carriage before and after it, on the front header of heat exchanger, be provided with domestic water import c and outlet b, on housing 11, be provided with heat medium import a and outlet d, at heat medium inlet tube 9 and housing 11 joints welding kitchen knife formula gusset 10, gusset 10 bottoms are arc (square) baffle plate 8 fixedly.Heat medium is entered by import a, and b discharges by outlet, and domestic water enters tube side by import c.After in shell-and-tube heat exchanger 2, being heated, by exporting d L by the road, flowing in the water storing tank 1, and give the user with domestic water from its top mouth of pipe e.
The utility model also can be fixed in heat medium inlet tube 9 and take over 12, is taking over welding lacing wire 13 in 12, the foraminate dished disk 14 of lacing wire 13 bottom fixed bands.
