Abstract

The utility model provides an energy-saving cold-hot exchanger, comprising an electric water heater, a cold-hot exchanger, a safety valve, a control electromagnetic valve, a boiled water discharging tube, a warm boiled water discharging tube, a cold water inlet tube and a warm water tube. The utility model is characterized in that the hot and cold exchange water tube in the cold-hot exchanger adopts a triple sleeve tube structure; small tubes are sheathed in each middle tube; a big tube is sheathed outside a plurality of middle tubes. The utility model has reasonable structure, easy installation, easy operation and a triple sleeve tube structure. The contact area of heat exchange among the medium is increased to the largest extent and the loss is reduced to the lowest extent so that the heat exchange efficiency can be raised and the energy-saving cold-hot exchanger is suitable for the energy-saving water-boiling device.

Description

The energy-saving cold and heat interchanger

Affiliated technical field

The utility model relates to a kind of interchanger, particularly a kind of energy-saving cold and heat interchanger.

Background technology

Cold and hot exchange water pipe in the existing cool-heat-exchanger generally all is a double-decker, and the tubule circulation cold water of internal layer flows hot water between outer field bassoon and the tubule.Though also can carry out exchange heat, heat exchanger effectiveness is lower, energy loss is bigger.

Goal of the invention

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and exchange heat contact area between medium can be increased to maximum, thus the energy-saving cold and heat interchanger that improves exchange heat efficient and loss is minimized.

Summary of the invention

The purpose of this utility model can reach by following measure: a kind of energy-saving cold and heat interchanger, comprise electric water boiler, cool-heat-exchanger, safety valve, control magnetic valve, boiling water outlet pipe, warm boiling water outlet pipe, cold water inlet, warm water tube, it is characterized in that: the cold and hot exchange water pipe in the cool-heat-exchanger adopts the triple tube structure, be with tubule in every in the pipe, bassoon is placed in outside many middle pipes.

The purpose of this utility model can also reach by following measure: the boiling water outlet pipe communicates with middle pipe in the cold and hot exchange water pipe, and cold water inlet communicates with tubule and bassoon in the cold and hot exchange water pipe.

The utility model has following advantage compared to existing technology: rational in infrastructure, easy to install, adopt the triple tube structure, exchange heat contact area between medium is increased to maximum, loss is minimized, thereby can improve exchange heat efficient, be applicable in the energy-saving water boiler.

The specific embodiment

With reference to Fig. 1～Fig. 4, the utility model comprises electric water boiler 1, cool-heat-exchanger 2, safety valve 3, control magnetic valve 4, boiling water outlet pipe 5, warm boiling water outlet pipe 6, cold water inlet 7, warm water tube 8 etc.Wherein the cold and hot exchange water pipe 9 in the cool-heat-exchanger 2 is divided into tubule 9-1, middle pipe 9-2, bassoon 9-3 three parts, and adopts the triple tube structure, and in the pipe 9-2, many middle pipe boxes were in bassoon 9-3 inside during tubule 9-1 was placed in.Middle pipe 9-2 communicates with boiling water outlet pipe 5, and tubule 9-1 and bassoon 9-3 communicate with cold water inlet 7.

Temperature in opening warm boiling water outlet pipe 6 is turned on the tap, and under the tap water pressure effect, boiling water flows out from electric water boiler 1, enters cool-heat-exchanger 2 through boiling water outlet pipe 5, and boiling water is in the Clearance Flow of water pipe 9-1 and middle pipe 9-2.This moment, running water also entered cool-heat-exchanger 2 by cold water inlet 7, and running water and flows in the gap of pipe 9-2 and bassoon 9-3 in many in water pipe 9-1, and its flow direction and flow of hot water are to opposite.Therefore, boiling water cooling during cold water makes and is clipped in the pipe 9-2, the boiling water of cold water absorption simultaneously heat temperature is improved, and in warm water tube 8 flows back to electric water boiler 1, the running water temperature that promptly enters in the electric water boiler 1 has improved, reduce electric water boiler 1 and used the electrically heated time, thereby saved a large amount of electric energy.
