Abstract

The utility model discloses a hot water electrothermal gas energy saving quick generator, which is composed of a water supply connector, a water outlet joint, and a heat exchange element, wherein the heat exchange element is pressed into a wavy concave convex groove and a single piece of a convex table according to a V shape, and two single pieces are overlapped to form a group in the form of regular and reverse dislocation according to the V-shaped direction. The group and the group are dovetailed and overlapped to form the gap distance where gas can pass through or an electric hot plate can be arranged in the opposite direction of a convex table. Brazing plates are fixedly connected between the convex tables of the plate and the plate or the group and the group in the braze welding technology to form a meandering water flow channel of the group and the group, and the water flow channel is positioned in a honeycomb hole between the plate and the plate. Cold water flows in the honeycomb hole, is shunted and refined. The utility model has the advantages of short preheating time, quick temperature rise, and energy saving, changes a direct heating mode of an electric heating tube and water of an instant electric water heater, and uses a separating and heating structure of water and electricity to improve the electricity-proof safety factor of products.

Description

Electric heating, fuel gas energy-saving rapid hot water generator

Technical field

The utility model relates to the hot water generator in electric heating, the gas heater.

Background technology

Water heater has electrothermal heater and gas heater, is the household electrical appliance of Modern Family's indispensability, and it provides convenience for people's life, along with the raising of quality of life, and the quickening of rhythm of life, people require water heater that hot water can be provided fast.Existing electrothermal heater, an inner bag is mostly adopted in the conversion of its cold water, hot water, and the heat exchange elements electrothermal tube is wound on the inner bag, during running water process inner bag, make running water convert hot water to by electrothermal tube energising heating, its defective is that the cold water storage is many because the inner bag volume is big, only pass to water by the heat energy of electrothermal tube circumferential wall, if will make cold water convert hot water in the short period of time, just need to consume high-power electric energy, and preheating time be long like this, the power consumption source, general family holds and can't stand.The hot water generator of gas heater all adopts by fuel gas buring and conducts to the water pipe in the heat-conducting plate through heat-conducting plate, make the cold water in the water pipe become hot water, because the water pipe capacity is big, preheating time is long, and rapid heat dissipation in the heat-conducting plate diabatic process, so gas energy consumes greatly.

Summary of the invention

Technical problem to be solved in the utility model be to overcome the defective of prior art and provide a kind of preheating time weak point, quick heating, energy resource consumption is few, the thermal efficiency is high electric heating, fuel gas energy-saving rapid hot water generator.

Technical problem of the present utility model realizes by following technical proposal: electric heating, the fuel gas energy-saving rapid hot water generator, comprise water supply connector, water out adapter and heat exchange elements, it is characterized in that described heat exchange elements is pressed into the monolithic of corrugated tongue and groove and boss by " V " type, 2 monolithics are just misplacing closed assembly in groups by " V " type direction one anti-, group forms clearance distance with group with the identical in opposite directions closed assembly of boss, at sheet and sheet, between group and the group boss brazing sheet that is connected by soldering processes is set, the water flow passage that the formation group is full of twists and turns with group, in the honeycomb structure of this water flow passage between sheet and sheet, be provided with heater in the clearance distance between group and group.

Described heater is combustion gas.

Described heater is an electric hot plate, and the installation electric hot plate is that the generator of heater is a full-closed structure, promptly at its peripheral solid welding shrouding.

Described " V " type angle α=125 °-135 °.

Described corrugated being of a size of: a=6.5-8.5 millimeter, b=1.5-2.5 millimeter, c=0.7-1.5 millimeter.

Compared with prior art, the utility model heat exchange elements has adopted board-like corrugated honeycomb structure structure, current are evenly flowed in the honeycomb hole of heat exchange elements, carry out the branch stream thinning, heat transfer area is big, shortened preheating time, quick heating, thermal efficiency height has been saved the energy, according to watt level, can arbitrarily anticipate by customer requirement adds layer combination, and single chip architecture is simple for production, as long as a secondary mould is made monolithic, by the combination closed assembly heat exchange elements, also have high pressure resistant, high temperature resistant, shock resistance, superior functions such as low water drag, can be widely used in instant electric water heater and gas heater, aspect safety in utilization, solve instant electric water heater's electrothermal tube and the direct-fired mode of water, adopted water, electricity is separated the structure of heating, has improved the anti-electric safety coefficient of product more effectively.

The specific embodiment

In conjunction with above-mentioned accompanying drawing embodiment the utility model is remake and to describe in further detail.

Electric heating, fuel gas energy-saving rapid hot water generator (referring to Fig. 1-5) comprise water supply connector 5, water out adapter 6 and heat exchange elements.Water supply connector is the cold water water supply connector, and water out adapter is hot water effluent's joint, by soldering processes difference solid welding hot water effluent place below cold water water inlet place above the heat exchange elements and heat exchange elements.

Heat exchange elements is that the stainless steel material of δ=0.3 millimeter is made by the corrosion resistant thickness of acid-fast alkali-proof, and stainless steel substrates is pressed into the monolithic 1 of corrugated tongue and groove by " V " type 7, " V " type angle α=130 °, corrugated tongue and groove size when flow be 4m ³During/h, select the a=7.7 millimeter of Fig. 5 for use, b=2 millimeter, c=1.2 millimeter.While is just misplacing closed assembly in groups at each monolithic 1

drift angle place

2,2 monolithic of compacting boss by " V " type direction one anti-, and the boss of monolithic coincide in opposite directions, forms clearance distance behind group and the group closed assembly.Then in sheet and sheet, group and organize that thickness is set between the boss is 0.1 millimeter 99.99% fine copper weld tabs, heat to 1100 ℃ of high temperature through preheating and to carry out soldering welding, be fixed with one through insulation, cooling welding again, the water flow passage that the formation group is full of twists and turns with group, in the honeycomb structure 3 of this water flow passage between sheet and sheet, the arrow of Fig. 1 represents that water (flow) direction is full of twists and turns, and the clearance distance between formation group and the group burns heater within it or switches on and heat.

Described heater can be the combustion gas 4 of scheme 1, or the electric hot plate 8 of scheme 2, and the generator when being heater with the electric hot plate is a full-closed structure, promptly at generator periphery solid welding shrouding 9, in the passage between electric hot plate is enclosed in group and organizes.

When cold water when water supply connector flows into, the heating because fuel gas buring between group and the group in the clearance distance or electric hot plate are switched on, cold water flows through in each group honeycomb structure, flows through full of twists and turns water flow passage and heats gradually, become hot water at last and flow out, supply with the user and use from water out adapter.According to the watt level requirement, can add layer combination.
