Problems solved by technology
[0005] For this reason, the technical problem to be solved by the present invention is that the space of the coil in the prior art is seriously wasted due to the limitation of the bending radius, and the structure is not compact. The number is small, the heat exchange area per unit volume is small, and the volume is large; furthermore, a coil with compact structure, small volume, and high heat exchange efficiency and a heat exchanger with the coil can be provided to reduce space waste as much as possible.

Embodiment Construction
[0048] A coiled tube 1 described in this embodiment, the coiled tube 1 is composed of several arc-shaped tubes 2 whose head ends a and tail ends b are sequentially connected to form a continuous curved line, and the head ends a of the arc-shaped tubes 2 are and the angle spanning between the tail end b is greater than 180 degrees, and the head end a and the tail end b of the arc-shaped tube 2 are not on the same plane (see Figure 1a and Figure 1b As shown), in this embodiment, the angle spanned between the head end a and the tail end b of the arc-shaped tube is preferably 186 degrees, and the center line of the joint of two adjacent arc-shaped tubes 2 is connected to a connecting tube 9 The center line is connected tangentially, that is, the tail end b and the adjacent head end a are connected tangentially through a straight pipe (see Figure 1c shown). Therefore, the bending arc length of the coiled pipe 1 is as long as possible within the minimum bending radius, which not...

The invention relates to a coiler and a heat exchanger with the same. The coiler consists of a plurality of arc pipes which are sequentially connected end to end into a continuous bending line, wherein the spanning angle between the head end and the tail end of each arc pipe is 180 degrees; and the central line of a connecting part of two adjacent arc pipes is provided with a common tangential point, or the central line of the connecting part of two adjacent arc pipes is tangentially connected with the central line of a straight pipe. The space of a coiler in the prior art is seriously wasteddue to the limit of a bent radius, and the structure is not compact; the quantity of coilers of a heat exchanger with the coilers of the prior art is reduced within a unit volume, the heat exchange area in the unit volume is small, and the volume is large. In order to solve the problems, the invention provides the coiler which reduces the space waste as far as possible and has compact structure, small volume and high heat exchange efficiency and the heat exchanger with the same.
Description
technical field [0001] The invention relates to a coiled pipe and a heat exchanger, in particular to a coiled pipe and a heat exchanger with the coiled pipe. Background technique [0002] Heat exchangers, also known as heat exchangers, are equipment for exchanging heat between hot and cold fluids. In chemical, petroleum, power, food and other sectors, heat exchangers are widely used as heaters, coolers and condensers. According to the heat exchange method between hot and cold fluids, heat exchangers can be divided into three categories: ① partition heat exchangers ② contact heat exchangers ③ regenerative heat exchangers. Among them, the partition wall heat exchanger is divided into tube heat exchangers according to the structure of the heat transfer surface (such as shell and tube heat exchangers, snake tube heat exchangers, casing heat exchangers, spray heat exchangers, Air coolers, etc.) and plate heat exchangers (such as spiral plate heat exchangers, flat plate heat exch...
