CN2327291Y - High performance heat collector - Google Patents

Abstract

The utility model relates to a high performance heat collector which belongs to the range of metal products for daily use. In the utility model, the heating surface on the bottom, and the wall surface of the side body are in convex and concave shapes with certain depths, the groove of the heating surface on the bottom is in a scattering shape and is communicated with grooves on the edge and the wall surface to form a gas flow guiding groove. The outer sides of the convex and the concave wall surfaces of the heat collector are respectively provided with a barrel skirt, the edge of the bottom of the barrel skirt is lower than the heating surface on the bottom to form a gas collecting cover, and the barrel skirt forms a fuel gas passage with the convex and the concave wall surfaces of the heat collector. The utility model increases heat collecting areas and simultaneously can collect heat fuel gas and discharge the fuel gas along the gas flow guiding groove on the bottom and the fuel gas passage on the side surface, so that gas cushions can be prevented from generation to influence heat transfer, and the heat collecting efficiency is enhanced.

Description

Efficient heat collector

The efficient heat collector of the utility model belongs to daily metallic article category, relates to a kind of heat collector that enlarges the area of heating surface that has.

The heat collector that daily life is at present used mainly comprises: pot class (as boiling pot, cooking pot etc.) and kettle class etc., they all adopt metal material (as aluminium, iron, stainless steel etc.) to make.This class cooker (not comprising electric kettle, electric frying pan etc.) all is to adopt heat by the stove and accessory combustion fuel by the bottom of pot (comprising kettle, together following) to conduct in the pot, thereby finishes thermophilic digestion (or the cooking) in use.For energy savings, a lot of people carried out improving the research of efficiency of combustion, reached the best combustion effect by the optimal design to burner.The efficiency of combustion of present many burners reaches more than 90%, is exactly the problem of utilizing of heat yet a uncared-for problem is arranged, although fuel combustion is more abundant, but can effectively utilize seldom, and Here it is adopts thermal efficiency problem.Calculate according to result of the test, the thermal efficiency of adopting of daily cooking utensil is lower than 30% at present.Chinese patent 92204895 has been announced a kind of " the energy-conservation heating device of sheet efficient " is to utilize fin to increase the principle of area of dissipation, increase radiating rate, the hot side of adopting of radiator is provided with sheet projection heat supply sheet to adopt hot side with increase long-pending, improve and adopt thermal velocity, reach energy-conservation purpose; But this design increase adopt hot side long-pending in, ignored the making full use of of high-temperature fuel gas, do not reduce thermal resistance effectively yet, thereby influenced the raising of adopting the thermal efficiency.

The purpose of this utility model is: by improving the structural design of daily cooking utensil, it is long-pending that hot side is adopted in increasing, reduces thermal resistance, improves and adopt the thermal efficiency, thereby reach the purpose of energy savings.

The efficient heat collector of the utility model is at the cooker that uses on burner, and its bottom heating surface and lateral body wall are designed to the convex-concave shape of certain depth, and it is long-pending to adopt hot side with increase; In order to prevent to produce the conduction of air cushion influence heat, the groove of bottom heating surface is dispersion shape and is communicated with formation gas flow guiding groove with the groove of edge and wall, so that high-temperature gas is derived along groove, guarantees that the heating surface of cooker directly contacts with flame; There is a sheath skirt in the outside of heat collector convex-concave wall, and the bottom sides edge of sheath skirt is lower than the bottom heating surface, thereby constitutes a gas skirt, prevents the scattering and the convection current of high-temperature fuel gas; The interlayer that sheath skirt and heat collector convex-concave wall constitute is the passage that high-temperature fuel gas rises, and heat conducts to the inside of the heat collector of heat collector by the convex-concave wall.For boiling class heat collector, the shape of inside bottom also is concavo-convex, and is corresponding with the shape of heating surface; For culinary cooker, only the bottom heating surface is designed to the convex-concave shape, inside bottom is an even surface still, is convenient to the cooking and uses.

The accompanying drawing of the efficient heat collector of the utility model has 1.

Fig. 1: the structure diagram of the efficient heat collector of the utility model;

Introduce embodiment of the present utility model in detail below in conjunction with accompanying drawing.

The punching press of the utility model available metal material is made.Behind the water of packing in the inner core 1 of heat collector, be placed on the flame of stove and accessory, bottom outside 2 is heated, it is the water heating that the groove 3 of bottom and projection 4 absorption heats and its conduct to bottom inside, the high-temperature fuel gas that burning produces by heat collector bottom centre along the groove 3 of dispersion shape to the outer water conservancy diversion, thereby prevent to form air cushion and influence heat conduction, under the effect of sheath skirt 52 gas skirts that constitute bottom heat collector, collect high-temperature fuel gas, make its interlayer 6 upwards ascensions along sheath skirt and lateral body convex-concave wall formation, and be the water heating with the inwall that heat conducts to heat collector, combustion gas is discharged by outlet 7.

Because the hot side of adopting of whole heat collector amasss greatly, and has prevented the excessive and convection current of high-temperature fuel gas, made full use of the heat that burning produces, therefore adopt the thermal efficiency and improve greatly.

Claims (1)

1. the efficient heat collector of the utility model, it is characterized in that: the bottom heating surface of heat collector and lateral body wall are the convex-concave shape that certain depth is arranged, the groove of bottom heating surface is dispersion shape and all is communicated with formation gas flow guiding groove with the groove of edge and wall; There is a sheath skirt in the outside of heat collector convex-concave wall, and the bottom sides of sheath skirt constitutes a gas skirt along being lower than the bottom heating surface, and the convex-concave wall of sheath skirt and heat collector constitutes blast tube.
