Abstract

The utility model relates to a combined heating device, which belongs to the heat exchangers for boilers and common stoves. The utility model is a cavity which is formed by the twist of an outer wall, an inner wall, a bottom surface, and a top surface, and the cross section of the cavity presents a ring shape. The utility model is characterized in that the inner wall is formed by the twist of a regular curved surface which has the same center of the outer wall, and a distance exists between the regular curved surface and the outer wall for the convenient flow of fluid. The utility model has the advantages that the inner wall adopts a regular curved surface, so the contact area is increased by more than 5 times, the thermal efficiency is increased by more than 2 times, the time can be saved by more than 3 times, and the combustion cost can be saved by more than 3 times.

Description

The combined type heater

The utility model belongs to the heat exchanger of boiler and common stove.

The utility model is made former heat exchanger, and mostly to be cross section be ring-like cavity, and its inwall is cylindric or the square tube shape.The heating surface area of this heat exchanger is little, and the thermal efficiency is low, can not well reach the purpose with heat supply, is commonly especially now to drive heating installation and make this heat exchanger then effect is poorer.

For addressing the above problem, the utility model provides a kind of heating surface area big, the heater that the thermal efficiency is high.

The utility model is to realize like this; A kind of combined type heater, this heater is ring-like cavity for the cross section that is surrounded by outer wall, inwall and bottom surface and end face, the upper and lower of this heater outer wall is provided with water outlet product and water inlet, the inwall of this heater is that ruled surface surrounds, this ruled surface is concentric with outer wall, and leave distance with outer wall, be convenient to flowing of fluid.

Described heater, 2～8 these heater delivery ports are communicated with the chimney heat exchanger.

Described heater, this heater inwall curved surface cross section are that 4～20 V or U type are formed by connecting; The length of this V-type or U type is 50～1000mm, highly is 100～2000mm.

Described heater; The chimney heat exchanger is 2～6 parallel-plate chambeies or the column type chamber that places in the chimney; It highly is 500～1500mm, and parallel-plate chamber or top, column type chamber are provided with delivery port.The advantage and the good effect of this practical firewood type are:

1, this combined type heater inwall adopts ruled surface, improves contact area more than 4 times, and the thermal efficiency improves more than 1 times, and more than 2 times, joint burning cost is more than 2 times during joint.

When 2, this heater is used in combination,, made full use of the heat of stove, further improved heating surface area by the heating of chimney heat exchanger instrument.So make the thermal efficiency improve 1.5～3 times.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Embodiment one:

As shown in Figure 1 and Figure 2, the combined type heater is for to surround cylindrical cavity by outer wall 1, inwall 2 and bottom surface and end face, its cross section is ring-like, this heater outer wall 1 is cylindrical, its top is provided with water outlet 3, the bottom is provided with water inlet 4, and the inwall 2 of this heater is for ruled surface surrounds, and this ruled surface can be formed by connecting for 4～20 V or U type; The length of this V-type or U type is 50～1000mm, highly is that 100～2000mm present embodiment is that 14 V-type curved surfaces are formed by connecting along circumference, makes that like this inner wall area is 4 times of Double Circle heat exchanger heat exchange area.This ruled surface is concentric with outer wall 1, and leaves distance with outer wall 1, is convenient to flowing of fluid.When this heater uses separately, referring to Fig. 3.Be placed on this heater in the body of heater and place on the combustion chamber 6, its outer wall 1 is less than furnace wall 7.Make thermal source that combustion chamber produces carry out heat exchange along the inner and outer wall of this heater.Since inside and outside be heated, simultaneously the inwall heating surface area increases, admittedly can improve the thermal efficiency more than 2 times.

Embodiment two:

When the heater among the embodiment one is used by a plurality of these heaters of a plurality of stoves drives as needs, because the more further improvement of the waste heat of stove.Gather in same chimney as Fig. 3 and the waste gas that the exhaust outlet of stove is discharged shown in Figure 8, each delivery port was communicated with chimney heat exchanger 5 as Fig. 4, shown in Figure 5 when heater used jointly, and chimney heat exchanger 5 is 2～6 parallel-plate chambeies or column type chamber such as the Fig. 6, shown in Figure 7 that places in the chimney; It highly is 500～1500mm, and parallel-plate chamber or top, column type chamber are provided with delivery port.Three stoves drive three combined type heaters as shown in Figure 3, and the delivery port of these heaters connects chimney heat exchanger 5 to carry out discharging from the delivery port of chimney heat exchanger 5 after the post bake, has further improved the thermal efficiency.
