Abstract

The DC60 (27/04/54) Coiled Tubular Heat Exchanger is a new design product that has never been seen anywhere before.It is a heat exchanger used to exchange heat between gases and liquids with a broken appearance. Unlike conventional heat exchangers, fluid flows in a spiral, spiral-like tube. And connected in series to the pipes Including the entrance and exit The coiled tubing increases the heat transfer capacity to be high. Than a heat exchanger that uses a straight pipe, although it has the same area In addition, the use of pipes with flanges that It is a tube with external fins or internal fins to coiled in a circle, which also increases the heat transfer area, resulting in higher heat transfer capacity as well. The flow of liquid in a circular pipe is carried out in two ways: inlet and out in the outer loop. Or flows into the outer circle and flows out into the inner circle As for the gas side It is arranged to flow into the center channel of one end of the shell and outflow at the ring-shaped area on the inner edge at the shell exit. This arrangement allows the gas to flow evenly through the coiled pipe surface. And increase the time to exchange heat with the liquid in the pipe that Curl more The coiled tubular heat exchanger is the result of a new design that has never been seen before.It is a heat exchanger that exchanging heat between gases and liquids with a different character than conventional heat exchangers. The liquid will flow in a tube that is coiled in a spiral that is stacked. And connected in series to the pipes Including the entrance and exit The circular coiled tubing increases the heat transfer capacity. Than a heat exchanger that uses a straight pipe, although it has the same area In addition, the use of pipes with flanges that It is a tube with external fins or internal fins to coiled in a circle, which also increases the heat transfer area, resulting in higher heat transfer capacity as well. The flow of liquid in a circular pipe is carried out in two ways: inlet and out in the outer loop.

Claims (1)

1. A heat exchanger with a coiled tube. In general, a heat exchanger that Used in the heat exchange between gas and liquid, it consists of two parts: the shell. Of heat exchanger And part of the pipe group And pipes using heat exchanger The current will be a straight pipe. Which may be fins or without fins For the heat exchanger that The new fabrication differs from the original: The shell structure of the coiled tubular heat exchanger consists of the shell structure part (6), the channel plate for gas flow (5) and the channel plate. For gas outflows (8) at the inlet and outlet areas, a flange (14) is perforated (15) for easy installation, provided that the flange (14) of the heat exchanger has dimensions. Fit the size of The flange of the system where the heat exchanger will be installed. The spiral-like tube (3) consists of several spiral-like tubes. Arranged Stacked, where the ends of each coil inside and outside are connected to the combined tube (1) for that number of coils. Depending on the amount of heat transfer to be transferred Size of the outermost coiling radius of the spiraled pipe It depends on the size of the shell (6). There are four types of tubing used in the coiled tubing group (3) installed inside the shell (6) with The special characteristics are The spiral tubing group (3) is installed inside the shell section (6) and there is a channel plate for the inlet gas flow (5) each, the outlet plate for the outlet gas (8) is installed at both ends. of Part of the shell The gas flows into the shell through the center channel on the inlet (4), after which it is forced to flow. Radial exit From the innermost tube, through the coiled tube (3) outward (the outermost circle) near the shell part (6), as it flows through the coiled tube (3), heat is transferred. After that, the gas escapes from the lateral shell adjacent to the shell wall (7). This flow of gas to allow the longest heat transfer time between the two fluids and to force the gas to flow evenly through the coiled pipe group (3). The fluid portion of the fluid that flows in a loop (3) can be of two types: inlet and out in the outer loop. Or flows into the outer circle and It flows in the inner ring and in the gas portions into the center cavity of the cylindrical shell (4) and flows through the annular cavity at the inner edge of the cylindrical shell (7).
