Embodiment Construction

[0017] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the heat exchange tube for a heat exchanger in this embodiment includes a tube body 2 with a through hole 3 in the middle of the tube body 2 , and U-shaped fins 1 arranged in parallel and at intervals are respectively installed on the upper and lower ends of the tube body 2 .

[0019] The U-shaped fins 1 are welded on the outer surface of the tube body 2 .

[0020] The bottom of the U-shaped fin 1 forms a planar structure 4 .

[0021] The center-to-center distance a between two adjacent U-shaped fins 1 is 10mm-50mm.

[0022] The invention has the advantages of reasonable structure, convenient manufacture, large heat exchange area, good heat exchange effect and good logistics circulation.

[0023] The present invention can be applied to heat exchangers, and can also be applied to high-pressure mixers, an...

Abstract

The invention relates to a heat exchange tube for a heat exchanger. The heat exchange tube comprises a tube body, a through hole is formed in the middle of the tube body, and a plurality of U-shaped fins parallelly arranged at intervals are respectively mounted at the upper end and the lower end of the tube body. By the aid of the uniformly arranged U-shaped fins welded on the tube body, heat exchange area is increased, heat exchange efficiency is high, the heat exchange tube is small in heat resistance and flow resistance, low in heat inertia and sensitive, space and power are saved, heat exchange components are mounted inside a shell of the heat exchanger by means of welding, the number of heat exchange tubes is decreased, and the heat exchanger can be high in pressure bearing capacity and fine in heat exchange effect by the aid of the small-sized shell and fewer heat exchange components.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a heat exchange tube for a heat exchanger. Background technique [0002] A heat exchanger (also known as a heat exchanger) is a device that transfers heat from one heat-carrying medium to another heat-carrying medium. In industrial production processes, heating or cooling is often required, that is, heat transfer. When one fluid exchanges heat with another fluid and does not allow mixing, it is required to be carried out in a partition heat exchanger, which is used in chemical, petroleum, power, food and other industries. The main function of the heat exchanger is cold and hot Heat energy exchange between fluids. [0003] The heat exchange tube is the core component of the heat exchanger, and its performance directly affects the performance and application of the heat exchanger. The heat exchange tubes usually used in the prior art are cylindrical tubes, and multiple h...
