Abstract

The utility model relates to a heat exchanger, in particular to a compact type U-shaped tubular heat exchanger structure. A row of U-shaped tubes arranged at the innermost part of the device are distributed in an inclined way, so that a middle channel of a U-shaped tube bundle is narrowed; the bending radiuses of the elbow sections of the U-shaped tubes arranged at the innermost part are not smaller than the two times of the external diameter of a heat exchange tube; a middle stop tube is arranged at the middle channel of the U-shaped tube bundle. After the compact type U-shaped tubular heat exchanger structure is adopted, the structure is compact, fluid short circuit is prevented, the heat exchange efficiency is improved, and the cost is lowered. The defects that the existing U-shaped tubular heat exchanger is not compact in structure, easily causes fluid short circuit and is low in heat transfer efficiency can be overcome.

Description

The U-shaped pipe heat exchanger structure of a kind of compact

Technical field:

The utility model relates to a kind of heat exchanger, particularly the U-shaped pipe heat exchanger structure of a kind of compact.

Background technology:

The U-shaped pipe heat exchanger structure of the many employings of existing shell-and-tube heat exchanger.The heat exchanger tube regulation of U-shaped pipe heat exchanger has minimum bending radius, makes the adjacent tube center distance in tube sheet pass partition groove both sides bigger than normal when straight type stringing, exists tube bank core to have space, the easy short circuit of fluid, affect heat transfer efficiency, on tube sheet, stringing radical is few, the problem that structure is not compact.

Utility model content:

The technical problems to be solved in the utility model is to provide the U-shaped pipe heat exchanger structure of a kind of compact, and this device has been realized compact conformation, prevents fluid short circuit, improves heat exchange efficiency, reduces costs.Overcome existing U-shaped pipe heat exchanger structure not compact, the easy short circuit of fluid, the deficiency that heat transfer efficiency is low.

Technical solution adopted in the utility model is: the U-shaped pipe heat exchanger structure of a kind of compact, comprises the U-shaped pipe of the inside one row; The U-shaped pipe inclination stringing of the inside one row narrows the center-aisle of U-shaped tube bank, and the bending radius of the U-shaped pipe bend loss of the inside one row is not less than the heat exchanger tube external diameter of twice, and the center-aisle place of U-shaped tube bank arranges middle apron pipe.

The beneficial effects of the utility model are: the utility model is owing to having adopted the U-shaped pipe inclination stringing of the inside one row, thereby have advantages of compact conformation, improve heat exchange efficiency, reduce costs; Owing to being provided with middle apron pipe, thereby can prevent fluid short circuit.

Accompanying drawing explanation:

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is U-shaped bend pipe oblique arrangement and middle apron pipe layout drawing.

The specific embodiment:

As shown in Figure 1 and Figure 2, the U-shaped pipe heat exchanger structure of a kind of compact, comprises the U-shaped pipe 1 of the inside one row; The U-shaped pipe 1 inclination stringing of the inside one row narrows the center-aisle of U-shaped tube bank, and the bending radius of U-shaped pipe 1 bend loss of the inside one row is not less than the heat exchanger tube external diameter of twice, and the center-aisle place of U-shaped tube bank arranges middle apron pipe 2.

Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.

Claims

1. the U-shaped pipe heat exchanger structure of compact, comprises the inside one U-shaped pipe of row (1); It is characterized in that: the inside one row's U-shaped pipe (1) inclination stringing narrows the center-aisle of U-shaped tube bank, the bending radius of the inside one row's U-shaped pipe (1) bend loss is not less than the heat exchanger tube external diameter of twice, and the center-aisle place of U-shaped tube bank arranges middle apron pipe (2).
