Abstract
The utility model discloses a heat exchanger of a water dispenser, which comprises a hollow coil and an inner tube arranged in the hollow coil; both ends of the hollow coil are provided with three-way connectors; both ends of the inner tube respectively extend out one interface of the three-way connectors; the inner wall of the outer end of each interface is separated from the outer wall of the inner tube; diversion channels are formed between the other interfaces of the three-way connectors, the hollow coil and the outer wall of the inner tube; the inner tube arranged in the hollow coil is a spiral structure; the three-way connectors are threaded three-way connectors; both ends of the threaded three-way connectors are provided with thread, and the other end is not provided with thread; the end without thread of each threaded three-way connector is sealed and connected with the inner tube; the positions at which the three-way connectors are sealed and connected with the inner tube are welded in an argon-arc welding form; the inner tube is a red copper tube; the hollow coil is a stainless steel tube or an aluminum tube. The heat exchanger of the water dispenser of the utility model has quite high heat exchange efficiency, and can save energy.
Description
Technical field
The utility model relates to a kind of heat exchanger of water dispenser, particularly a kind of heat exchanger that can go out the big flux water dispenser of boiling water and warm boiling water simultaneously.
Background technology
At present, water dispenser on the market, boiling water can be provided, can provide warm boiling water again, the temperature boiling water is produced by heat exchanger, and running water is after having absorbed the boiling water dispersed heat by heat exchanger, enters to be heated into boiling water in the water courage again, such structure has been utilized dispersed heat, has saved the energy greatly.As the patent No. be: 02271164.3, the heat exchanger of water dispenser, comprise a hollow coil pipe and the three-way connection that is located at hollow coil pipe two ends, at least be provided with pipe in two in the hollow coil pipe, because pipe is a straight tube in it, boiling water and running water are very fast at interior pipe flow velocity, and the speed of heat exchange is slow, and heat exchanger effectiveness is lower, and interior pipe is more, stops up easily, increased the cost of water dispenser.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the water dispenser heat exchanger that a kind of heat exchanger effectiveness is higher, save the energy is provided.
Goal of the invention of the present utility model is to realize like this, a kind of heat exchanger of water dispenser, comprise a hollow coil pipe and be located at the interior interior pipe of hollow coil pipe, the two ends of hollow coil pipe are provided with three-way connection, an interface of three-way connection is extended at interior pipe two ends respectively, seal between the inwall of this interface outer end and the outer wall of inner tube, form flow-guiding channel between two other interface of three-way connection and hollow coil pipe, the outer wall of inner tube, it is characterized in that: the described pipe that is positioned at hollow coil pipe is a helical structure.
Described three-way connection is the screw thread three-way connection, and there is screw thread at the two ends of screw thread three-way connection, and an end does not have screw thread, and no screw thread one end is connected with the interior seal of tube.
The place of being tightly connected between described three-way connection and the interior pipe adopts the argon arc welding welding.
Pipe is copper tube in described.
Described hollow coil pipe is a stainless steel tube.
Described hollow coil pipe is an aluminum pipe.
The utility model improves by the heat exchanger to the water dispenser of prior art, the inner and outer pipes two ends are connected by each water pipe line of screw thread threeway and water dispenser, boiling water flows at the copper tube inside spin, the slit helical flow of running water between hollow coil pipe and copper tube, boiling water and running water are that contrary direction flows.Because interior pipe is a helical form, has more effectively promoted heat exchange, energy savings.The utility model reasonable in design, environmental protection and energy saving, alleviated water dispenser weight, reduced cost.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Accompanying drawing 2 is the utility model theory structure schematic diagram.
Accompanying drawing 3 is figure A-A sectional view.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to shown in Figure 1, the heat exchanger of water dispenser of the present utility model, comprise a hollow coil pipe 1, manage 2 in one in the hollow coil pipe 1, this hollow coil pipe 1 can be stainless steel tube, aluminum pipe or other meet the circle or the square tube of drinking water hygiene condition, and interior pipe 2 is a copper tube, hollow coil pipe 1 two ends are provided with three-way connection 3, this three-way connection 3 is the screw thread three-way connection, hollow coil pipe 1 is an outer tube, copper tube is interior pipe 2, be somebody's turn to do interior pipe 2 shape in the shape of a spiral, the two ends of copper tube extend to an interface 4 of screw thread three-way connection respectively, weld with argon arc at the screw thread three-way connection inwall of these interface 4 outer ends and the gap between copper tube 2 outer walls, guarantee sealing, the gap between the outer wall of two other interface 5 of screw thread threeway 3 and the inwall of hollow coil pipe 1 and copper tube 2 forms a cold water road 6.Boiling water enters from an end of interior pipe 2, flow out from the other end of interior pipe 2, running water enters hollow coil pipe 1 from an interface 5 of screw thread three-way connection, flow out from another interface 5, boiling water flows at copper tube 2 inside spins, the slit helical flow of running water between hollow coil pipe 1 and copper tube 2, boiling water and running water are that contrary direction flows.Heat exchange takes place in boiling water and running water in hollow coil pipe 1, make running water preheating before heating, and boiling water becomes warm boiling water and directly drinks, promoted heat exchange effectively, and interior pipe and outer tube be one respectively, avoided stopping up in the pipe, reduced the manufacturing cost of water dispenser.
