Problems solved by technology

[0004] Different from the traditional baffle oil cooler, the shell side fluid of the new oil cooler generally flows axially, so the shell side fluid flow rate is usually low, which leads to the low heat transfer coefficient of the shell side fluid, so it is only suitable for the shell side occasions with large traffic

Embodiment

[0033] Please refer to figure 1 and image 3 As shown, a longitudinal turbulent flow oil cooler with adjustable shell-tube volume includes a shell 7, and the two ends of the shell 7 are closed by two tube sheets 2 to form an accommodating space. The shell 7 A plurality of heat exchange tubes 8 are installed inside, and the plurality of heat exchange tubes 8 are bound by clamps 5 to form a heat exchange tube bundle. Flow channel, the two ends of the heat exchange tube bundle are respectively fixed on the corresponding tube sheet 2 and communicated with the corresponding flow channel, one of the flow channels is divided into tubes through the partition to improve the heat exchange efficiency, which will flow the The channel is divided into a chilled water inlet channel and a chilled water outlet channel. A chilled water inlet 1 and a chilled water outlet 10 are arranged on the corresponding head of the flow channel. The chilled water inlet 1 communicates with the chilled water ...

Abstract

The invention discloses a tube shell pass volume-adjustable longitudinal turbulence oil cooler. The cooler comprises a shell, wherein the two ends of the shell are respectively closed by a first pipe plate and a second pipe plate to form an accommodating space; multiple heat exchange pipes are mounted in the shell, and comprise a deformed heat transfer pipe and first and second round pipes connected to the two ends of the deformed heat transfer pipe, wherein the first round pipe is fixed on the first pipe plate; the second round pipe is fixed on the second pipe plate; the first round pipe, the deformed heat transfer pipe and the second round pipe are the same in perimeters of cross sections; the adjacent heat exchange pipes realize the point contact through projection parts on the deformed heat transfer pipe to form a self-support structure; and gaps correspondingly formed between adjacent two contact points of the adjacent heat exchange pipes are formed to a netty channel in the accommodating space. The cooler realizes the tube / shell pass space control through the deformed heat transfer pipe, and can form a uniform and compact spiral runner in the shell pass to achieve a strong disturbance effect on a shell pass fluid, so that the shell pass heat transfer coefficient can be largely improved.

Description

technical field [0001] The invention relates to the technical field of oil cooler manufacturing, in particular to a turbulent flow oil cooler with adjustable tube and shell side spaces used in petrochemical, electric power, metallurgy and other industries. Background technique [0002] As a traditional oil cooler structure, the shell-and-tube oil cooler has the characteristics of simple structure, low manufacturing cost, convenient maintenance, strong applicability, high safety, wide range of material selection, and large processing capacity. In the shell-and-tube oil cooler, the traditional baffle structure has always occupied a dominant position. However, because the baffle structure is a flow dead zone at the junction of the baffle and the shell, eddy currents are formed at this position, which leads to problems such as reduction of effective heat exchange area, scaling and corrosion. At the same time, due to the flow state of the shell side For the overall countercurren...
