As shown in fig. 1 to 5, a frying pan of the present utility model includes a plurality of heat transfer fins 10, the plurality of heat transfer fins 10 being connected to a central portion of an outer surface of a bottom of the frying pan, the plurality of heat transfer fins 10 being spaced apart from each other, and a curved first passage 11 through which a heating air flow is formed between adjacent two of the heat transfer fins 10. The plurality of heat exchange columns 20 are connected to the non-middle outer surface of the bottom of the wok, the plurality of heat exchange columns 20 are distributed on the outer sides of the plurality of heat transfer fins 10 in a surrounding mode, and adjacent heat exchange columns 20 are arranged at intervals.

In particular, the plurality of heat exchange columns 20 are preferably cylindrical aluminum alloy products; the plurality of heat transfer fins 10 are preferably made of stainless steel, and the use of stainless steel can save the cost in terms of processing and manufacturing.

The hot gas flow at the plurality of heat transfer fins 10 flows first along the arc-shaped section of smaller curvature and then the hot gas flow flows axially along the arc-shaped section of progressively larger curvature. The configuration of the plurality of arcuate segments allows for the circulation of the hot gas flow.

The hot air flow is hot fluid such as flue gas generated by combustion of fuel gas; the outer surface of the bottom of the frying pan is a combustion surface which is directly contacted with hot fluid such as smoke generated by gas combustion.

The first channel 11 is a channel formed by two adjacent heat transfer fins 10, so that hot fluid such as smoke generated by gas combustion flows to the heat exchange columns 20, and the outer surface of the bottom of the wok is heated uniformly.

The middle part is a high temperature area which is directly contacted with open fire for heating when the bottom of the frying pan is cooked, and the high temperature area is one half or one third of the bottom of the frying pan; the non-middle part is the area outside the middle part area of the outer surface of the bottom of the wok.

In one embodiment, the plurality of heat transfer fins 10 are radially distributed on the outer surface of the bottom of the wok at the center of the wok.

Specifically, the plurality of heat transfer fins 10 are preferably arranged radially around the center of the frying pan on the outer surface of the bottom of the frying pan. The annular shape is beneficial to outward diffusion of hot air flow in the middle of the bottom of the frying pan, a large heat transfer area is formed, the outer surface of the bottom of the frying pan is kept uniformly heated, and the heat transfer efficiency of the middle and non-middle parts of the bottom of the frying pan is improved.

In one embodiment, the plurality of heat transfer fins 10 comprise a plurality of arcuate segments connected in series, with the curvature being different between the arcuate segments. The curvature of the plurality of arc-shaped sections of the plurality of heat transfer fins 10 gradually increases in sequence along the flow direction of the hot gas flow.

Specifically, the hot air flows at the arc sections firstly flow along the axial direction with smaller curvature, and then the hot air flows along the axial direction with gradually increased curvature, so that the hot air can flow circularly.

In one embodiment, the cross-sectional profile shape of the plurality of heat transfer fins 10 is involute.

Specifically, the involute is formed by fixing a circular shaft on a plane, winding a wire on the shaft, tensioning a wire head, enabling the wire to move around the circular shaft and be always tangent to the circular shaft, and then a locus of a fixed point on the plane on the wire is the involute.

Compared with other curves such as concave-convex lines, the involute is better in flow continuity of hot fluid such as smoke generated by gas combustion, heat is transferred along the tangential direction in the flow direction of the hot fluid, and the heat transfer efficiency of the frying pan is improved.

In one embodiment, the plurality of heat exchange columns 20 are arranged in a plurality of rows at intervals, and the plurality of heat exchange columns 20 in each row are arranged in a circular ring; and heat exchange columns 20 in two adjacent rows are arranged in a staggered manner.

In particular, the plurality of heat exchange columns 20 are preferably aluminum alloy materials, which is an excellent heat conductor to maximize the heat conducting surface area of the frying pan.

The multiple rows are arranged at intervals, preferably a plurality of circles, and are arranged at intervals in a progressive manner at the middle part by the outer layer according to the shape and the size; because the area of the circle is larger than that of any other shape, the same amount of materials can be made into the material with the largest volume, and further, the material is saved and the heated area of the frying pan is increased.

In one embodiment, the plurality of heat exchange columns 20 are vertically connected to the outer surface of the bottom of the wok.

The plurality of heat exchange columns 20 are preferably arranged on the outer surface of the bottom of the wok in a radial mode around the center of the wok, are arranged at intervals, are welded on a side wall surface of the outer edge of the outer surface of the bottom of the wok vertically, have no edges and corners, are small in integral friction coefficient, are better in safety, and are prevented from being damaged easily, and meanwhile dense heat channels are increased.

In one embodiment, the heat exchange columns 20 are arranged to form a circular structure with the heat transfer fins 10 as the center;

the number of the rows is not less than 7 rows;

the number of the heat exchange columns 20 in each row is not less than 36;

the material of the plurality of heat transfer fins 10 is stainless steel;

the plurality of heat exchange columns 20 are made of aluminum alloy.

Specifically, the heat exchange columns 20 are arranged in a plurality of rows at intervals as much as possible, and a sufficient number of heat exchange columns 20 in each row are matched to form a sufficient heating area.

In one embodiment, the wok includes a handle.

Specifically, the handle is made of plastic or metal and the like, preferably light in weight, high in temperature resistance and durability, and is matched with a simple decorative design, so that the aesthetic feeling of the frying pan is improved while the frying pan is convenient to clean.

The working principle of the pot of the utility model is as follows: the hot fluid such as flue gas generated by gas combustion is transferred to the other side wall surface from the wall surface of the frying pan close to the fire source in a heat conduction mode, heat is transferred to the material to be heated from the wall surface of the frying pan in a convection mode, air close to the fire source is heated and expanded to rise, and the hot air axially flows along a plurality of arc-shaped sections which are arranged in a central symmetry mode, so that hot air circulation is formed, and the loss is not easy. Because the heat transfer fins 10 and the heat exchange columns 20 have temperature differences, the convection direction is positive in the direction of temperature reduction, so that hot air is transferred from the heat transfer fins 10 to the heat exchange columns 20, and the heat transfer fins 10 are required to be arranged in an array as many as possible, and the heat exchange columns 20 are matched to form a larger heat transfer area, so that heat is brought to all positions of the frying pan.

Other structures of a frying pan in this embodiment are known in the art.

The above is only a preferred embodiment of the present utility model, and is not limited in any way, so any modification, equivalent variation and modification made to the above embodiment according to the technical substance of the present utility model still fall within the scope of the technical solution of the present utility model.
