Abstract

The utility model relates to modified cookware with high thermal conductivity, which comprises a cookware body. The bottom of the cookware body is manufactured to be inwardly depressed to increase the area of a thermal conducting bottom surface, thereby improving thermal conducting efficiency and achieving the purposes of saving energy and improving efficiency.

Description

The pan of modified high thermoconductivity

[technical field]

The utility model relates to a kind of pan, more particularly, relates to a kind of pan of modified high heat transfer efficient.

[background technology]

Family expenses are cooked to cook and are used pan usually.Except using on special heating sources such as electromagnetic oven, the absolute majority pan is to use the external heat source heating.Owing to use external heat source, heat must conduct to pot nside from the pan bottom.Certainly, in order to improve the thermal source service efficiency, people have expected that a lot of ways improve stove and accessory, and its combustion gas utilization ratio is improved, and reach the purpose that conserve energy is raised the efficiency.Present pan all is the common pan of circular flat bottom, and during boiling, heat utilization ratio is low, wastes energy.The inventor expects equally also can trying every possible means by improving the structure of heating container (pan), realize identical purpose, mentioned in the application of the former proposition of inventor bottom of pot body has been fabricated to fold shape, and then the increase heating surface area, improving heat transfer efficiency, it has certain effect, but at the energy of advocating thriftiness, the current society that raises the efficiency, people wish to obtain higher heat transfer efficiency, utilize the energy more fully.

[utility model content]

To achieve these goals, here, the inventor has designed a kind of follow-on pan, it has greatly increased the heating surface area of pan, and has improved the form of thermal convection current in the pot body, has greatly improved heat utilization efficiency, improve heat transfer efficiency, saved the energy better, improved boiling efficiency.

Specifically, the utility model provides a kind of pan, comprises pan body, pot cover and handle, the body bottom manufactures and caves inward, and increases heating surface area whereby, improves thermal cycle, thermal convection current in the pot body, final raising pyroconductivity, energy savings, the purpose of raising the efficiency of realizing.

In a preferred embodiment, the bottom of described body is manufactured into the prismatoid that caves inward, because prismatoid has certain altitude, trapezoidal body wall around this height becomes heating surface, under the situation of big or small on an equal basis floor space, increase this height and just can increase thermal interface, thereby, heat transfer efficiency improved; In addition, than traditional pan, the pot nside structural change, the heat conduction no longer is from planar base, upwards conducts heat, but from prismatoid each towards around conduct heat, this heat transfer pattern has changed thermal convection current, thermal cycle form, makes water convection velocity quickening in pot body, like this, under the situation of same external heat source, adopt the boiling efficiency of pot body of this convection model higher.

In another preferred embodiment, the bottom of described body is manufactured into the cone that caves inward, and its principle is similar with the prismatoid of above-mentioned embodiment.But owing to adopt conically shaped body, it is comparatively different with prismatoid that heat outwards conducts the convection current, the circulation that cause, adopt this conical physical efficiency to improve the thermal convection current form better, more can improve the water convection velocity, realize than the higher boiling efficiency of above-mentioned prismatoid embodiment.

Principle of the present utility model is that the shape that caves inward is made in the pan bottom surface, and described shape comprises all shapes that can realize the utility model purpose.

By the embodiment of such scheme, the utility model is by improving pan structure, and heat conduction efficiency when improving boiling has realized energy savings, the purpose of raising the efficiency.

Fig. 2 is the schematic diagram of second preferred embodiment of the utility model pan and the upward view of described pan body bottom.

[specific embodiment]

With reference to Fig. 1, first preferred embodiment of the pan of modified high thermoconductivity of the present utility model is shown, described pan 20 comprises pan body 21, pot cover 22 and panhandle 23.Specifically, body bottom 25 manufactures the prismatoid 26 that caves inward, because prismatoid has certain altitude h, trapezoidal body wall around this height becomes heating surface, under the situation of big or small on an equal basis floor space, increases this height and just can increase thermal interface, thereby, improve heat transfer efficiency; In addition, than traditional pan, the pot nside structural change, the heat conduction no longer is from planar base, upwards conducts heat, but from prismatoid each towards around conduct heat, this heat transfer pattern has changed thermal convection current, thermal cycle form, makes water convection velocity quickening in pot body, like this, under the situation of same external heat source, adopt the boiling efficiency of pot body of this convection model higher.

With reference to Fig. 2, second preferred embodiment of the pan of modified high thermoconductivity of the present utility model is shown, the bottom 25 of described body is manufactured into the cone 27 that caves inward, and its principle is similar with the prismatoid of above-mentioned embodiment.But owing to adopt conically shaped body 27, it is comparatively different with prismatoid that heat outwards conducts the convection current, the circulation that cause, adopt this conical physical efficiency to improve the thermal convection current form better, more can improve the water convection velocity, realize than the higher boiling efficiency of above-mentioned prismatoid embodiment.

In the use, pan of the present utility model is placed on the conventional external thermal source, just can improves heat transfer efficiency, accelerate cooking speed.
