Description

Naked light spiral thermal-arrest plate energy saver

Technical field

The utility model belongs to a kind of naked light spiral thermal-arrest plate energy saver.

Background technology

At present, the project organization of plane, taper or circular arc is all adopted in the civilian pot of being sold on the market, the bottom of hot-water bottle.This traditional planar structure, flame all is in the i.e. linearly diffusion towards periphery of the moment in the contact the bottom of a pan, cause thermal source too short at the bottom of a pan range ability and the time of staying, the bottom of a pan only absorbs minimum partial heat energy, and most of heat energy is scattered and disappeared by very fast, thermal source can not get effective utilization, has wasted a large amount of energy.Have only the nearest pot center of distance fire to be heated at the bottom of the whole cooker, except that heat utilization efficiency was low, it is inhomogeneous that the bottom of a pan is heated, and causes the food of the cooking to be burned.

Summary of the invention

The purpose of this utility model is: design a kind of naked light spiral thermal-arrest plate energy saver, have the advantage energy-conservation, that heat utilization efficiency is high, simple in structure, simple for production, with low cost.For this reason, the utility model adopts the outer pot bottom surface to be provided with the spiral plate thermal-arrest energy-saving device, described spiral plate thermal-arrest energy-saving device is made of the circle that blocks that is circular-arc long helical fin, middle helical fin, short helical fin and helical fin periphery, described length, in, the tail end of short helical fin is positioned on the same circumference, long, in, short helical fin by long, in, short circulation successively is provided with.The said structure design has realized the purpose of this utility model.

The utility model has the advantages that:

One, increased flame stroke and the heated time on the face of the bottom of a pan outside.The bottom of a pan (or outer bottom of other cooker) is behind the spiral plate thermal-arrest energy-saving device that is welded, changed the heat energy dispersal direction of flame, spread by linearly spreading to become towards periphery originally along spiral plate thermal-arrest energy-saving device direction spiral, the heat energy of flame prolongs 0.5 times relatively at the stroke in the bottom of a pan, the heat diffusion speed of flame is slowed down, thereby prolonged the bottom of a pan heated time, so improved the heat energy conversion utilization rate, reached energy-saving effect.

Two, be welded on the outer pot bottom surface and increased the bottom of a pan heating surface area behind the spiral plate thermal-arrest energy-saving device.The spiral plate thermal-arrest energy-saving device is a vertically-arranged, can three (mainly being both sides) be heated, and normally is heated under the situation not influencing the former the bottom of a pan, has increased heating surface area again.Increase about 50% than conventional planar the bottom of a pan heating surface area, thereby make heat energy conduct to the bottom of a pan face rapidly.During use, helical fin is very fast promptly to be burnt red by flame.According to heat conduction and physical temperature relative equilibrium principle, the high-temperature region is to low-temperature space diffusion conduction, and the heat energy of the helical fin of relatively-high temperature can conduct to the relatively low the bottom of a pan of temperature very soon, and is absorbed by the bottom of a pan, has improved the heat absorption conversion efficiency.

Three, flame is through the bottom of a pan and spiral plate thermal-arrest energy-saving device the time, also have partial heat energy to scatter and disappear after being absorbed most of heat energy, thereby the utility model has also designed the same shirt rim of similar Great Wall crenel and has promptly blocked circle, block and utilized residue flame part heat again, further increase thermal conversion rate, further improved energy-saving effect.Improve 20-25% through energy-conservation conversion ratio behind the spiral plate thermal-arrest energy-saving device that is welded, energy-saving effect is fairly obvious.

Four, applied widely.The utility model is applicable to that with natural gas, coal gas, liquefied petroleum gas, biogas, coal, faggot etc. all are cookers such as flat, the conical bottom of iron, aluminium, copper, stainless steel, cast iron (casting iron pan is one-shot forming when casting then) of thermal source and the frying pan at the bottom of the circular arc, digester, kettle teapot with the naked light.Also be applicable to that energy-saving effect is obvious equally on the identical or akin industrial equipment of principle.

The specific embodiment

As shown in Figures 1 to 4, a kind of naked light spiral thermal-arrest plate energy saver mainly is made up of pot body 2, handrail 1 and outer pot bottom surface 4.The outer pot bottom surface is provided with the spiral plate thermal-arrest energy-saving device.

As depicted in figs. 1 and 2, described spiral plate thermal-arrest energy-saving device is made of 3 on the circle that blocks that is circular-arc long helical fin 5, middle helical fin 6, short helical fin 7 and helical fin periphery, described length, in, the tail end of short helical fin is positioned on the same circumference, long, in, short helical fin by long, in, short circulation successively is provided with.

Described length, in, short helical fin spacing distance is provided with.Described block circle be arranged in long,, on the outer outer pot bottom surface of short helical fin tail end.

As shown in Figure 3, the described last spacing distance of circle that blocks is provided with crenel 8.The effect of crenel is that flue gas is discharged.

As shown in Figure 4, described length, in, short helical fin is trapezoidal that head end is low, tail end is high.Described length, in, the head end of short helical fin is positioned at middle part, outer pot bottom surface.Described length, in, the length ratio of short helical fin is 3: 2: 1.

In addition, no matter cooker bottom surface diameter, when being welded the spiral plate thermal-arrest energy-saving device, the clear area of diameter 40mm is all stayed at center, the bottom of a pan.Block circle and leave the spacing of 15mm apart from the helical fin tail end.The used material of spiral plate thermal-arrest energy-saving device is identical with the cooker material, and per three of helical fin is one group, be divided into long, in, short helical fin, totally 8 groups.Tail end is the bottom of a pan face outside outside, and head end is in the bottom of a pan face inboard, helical fin length one side and the welding of outer pot bottom surface outside.Clockwise spiral or counterclockwise spiral all can, energy-saving effect is identical.

Block circle and be provided with the crenel that is the Great Wall shape.One side and pot or kettle firm welding of gap will be cut.Each helical fin and block circle all must logical weldering, must not spot welding.Otherwise can influence energy-saving effect.

The spiral plate thermal-arrest energy-saving device of casting iron pan can be shaped by one-step casting when skillet.

In a word, the utility model is with the stroke of relative prolongation flame at the bottom of the bottom of a pan or kettle, increases pot or kettle and inhales Receive time and the heating surface area of heat energy, reach the raising thermal conversion rate, have energy-conservation, simple in structure, use model Enclose wide, simple for production, with low cost and price is low, quick combustion and the high advantage of heat utilization efficiency, can promote making With.
