Outer coil pipe is wrapped in by heat exchange coil on enamel cistern inner bladder outer wall, the water in inner bag is passed to again, because it does not contact with water, so there is not the problems such as fouling corrosion after coil pipe and wall of inner container heat exchange, but the thermal contact resistance of coil pipe and wall of inner container is large, causes heat transfer efficiency lower.For this problem, in industry, generally believe that the contact area that can increase coil pipe and wall of inner container is improved.Start coil pipe to be made into D type, increase the contact area of coil pipe and wall of inner container.After develop again microchannel aluminium band type heat exchanger, further increase the contact area with wall of inner container.Heat transfer efficiency increases, but thermal contact resistance is still very large, and heat transfer property improves limited.
Summary of the invention
The object of the invention is to change the prejudice generally believing in industry and only have the contact area by increasing coil pipe and wall of inner container to improve heat transfer efficiency, adopt the method that coil pipe welds with wall of inner container, significantly reduce thermal contact resistance thus improve heat transfer efficiency.
The technical scheme that the present invention takes is: a kind of external coiled pipe type enamel cistern heat-exchange inner container, comprise enamel inner container and coil pipe, described outer coil pipe is coiled on the outer wall of inner bag ladle body tightly according to certain interval, and contact surface between coil pipe and inner bladder outer wall adopts solder stick both to be welded as a whole.
Due to the contact surface between coil pipe and inner bladder outer wall adopting solder stick both to be welded as a whole, make thermal contact resistance between coil pipe and inner bladder outer wall close to 0, thus improve heat transfer efficiency significantly.Contact surface in addition between coil pipe and inner bladder outer wall adopts solder stick both to be welded as a whole, makes structure between the two more firm.Add outer coil pipe not contact with water, so there is not the problem such as fouling and corrosion, higher heat transfer efficiency can be remained on the one hand, substantially prolongs the service life of heat-exchange inner container, on the other hand, without the danger of coil pipe burn into perforation, use more safe and reliable.
Further, can coil between coil pipe and inner bag and weld, weld again after also can having coiled between coil pipe and inner bag.
Can coil between coil pipe and inner bag while be welded with and be beneficial to raising work efficiency.Be welded with again after having coiled between coil pipe and inner bag and be beneficial to raising welding quality.
Further, described coil pipe is the coil pipe that the coil pipe of 1, more than 2 or 2 is formed in parallel.
Single coil is conducive to simplifying production technology, and many coil pipes are parallel with the flow resistance being beneficial to and reducing liquid refrigerant.
Further, described coil pipe is copper pipe or stainless steel tube.
Copper pipe heat transfer resistance is little, price, and stainless steel tube heat transfer resistance is large, low price.
Further, described enamel inner container is a termination evagination, the enamel inner container of another termination indent.
When inner water tank adopts vertical placement, because coil pipe can only be coiled on the ladle body of inner bag, and can not be coiled on the termination of inner bag, during the termination indent of inner bag bottom, can guarantee that the cold water bottom inner bag also can all heat.
