Abstract

The invention discloses a pure reverse flow shell pipe type fresh water cooler which comprises a first pipe box, a shell and a second pipe box. The first pipe box and the second pipe box are connectedto the two ends of the shell correspondingly. A cooling core body is arranged in the shell. Pipe plates are arranged at the two ends of the cooling core body. The pipe plates are arranged at the twoends of the shell and seal and close an internal space of the shell. The first pipe box is provided with a pipe pass cooling water inlet. The second pipe box is provided with a pipe pass cooling wateroutlet. The side face of the shell is provided with a shell pass fresh water inlet and a shell pass fresh water outlet. The shell pass fresh water inlet is formed in the position close to the pipe pass cooling water outlet. The shell pass fresh water inlet is formed in the position close to the pipe pass cooling water inlet. According to the fresh water cooler, a three-dimensional deformation pipe is adopted for replacing a traditional heat exchange pipe bundle, the shell pass supporting form is changed, optimized design is carried out on the cooling core body, thus the heat exchange efficiency of the fresh water cooler is improved, pressure drop is reduced, and the purposes of light weight and compaction are achieved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a pure countercurrent shell and tube type fresh water cooler. Background technique [0002] The fresh water cooler is an important part of the marine diesel engine cooling system. Seawater is usually used as cooling water to cool high-temperature freshwater. Due to the strong corrosiveness of seawater, the material of the heat exchange tube bundle needs to be made of nickel-white copper tube, titanium tube and other precious metal materials. . The existing baffled shell-and-tube fresh water coolers have shortcomings such as low cooling efficiency and large flow resistance, resulting in many heat exchanger consumables, bulky, and high manufacturing costs, which limit the development of marine diesel engines in the direction of high efficiency, compactness and light weight. . SUMMARY OF THE INVENTION [0003] In view of the deficiencies of the prior art, the present inv...
