Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] A tubular ceramic cooler, comprising a hollow housing 1, a cooling liquid pipe 2 arranged in the housing 1, an oil inlet 3 and an oil outlet 4 arranged on the housing 1, the oil inlet 3 and the The oil outlet 4 is connected, one end of the cooling liquid pipe 2 is connected with the water inlet 5, and the other end is connected with the water outlet 6, and the cooling liquid pipe 2 is made of non-oxide ceramic material.

[0028] Non-oxide ceramic materials, as non-oxide high-temperature resistant structural materials, use silicon carbide, silicon nitride, aluminum nitride and other materials and siro silicon nitride solid solution as raw materials. Therefore, non-oxide high-temperature ceramics have excellent high-temperature strength, low thermal expansion coefficient, thermal conductivity close to that of metal, oxidation resistance, high-sulfur fuel...

Abstract

The invention discloses a tubular ceramic cooler, which comprises a hollow shell, a cooling liquid pipe, an oil inlet and an oil outlet. The cooling liquid pipe is arranged in the shell, the shell isprovided with the oil inlet and the oil outlet, the oil inlet and the oil outlet are communicated with each other, one end of the cooling liquid pipe is communicated with a water inlet while the otherend is communicated with a water outlet, and the cooling liquid pipe, the water inlet and the water outlet are made of non-oxide ceramic materials. Metal materials prone to corrosion are replaced bythe ceramic materials for manufacturing parts, contacting with cooling liquid, in the cooler, so that corrosion of the cooling liquid pipe is avoided without use of zinc blocks, cooler maintenance workload is reduced, maintenance cost is reduced, and the problem of oil contamination caused by oil-water mixing resulted from corrosion of the cooler is avoided. In addition, compared with an existingcooler, the tubular ceramic cooler has the advantage of cooler weight reduction due to low density of non-oxide ceramic.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a tubular ceramic cooler. Background technique [0002] Current seawater coolers are mainly made of copper tubes, relying on zinc blocks installed inside to improve the anti-corrosion performance of the cooler. At the same time, the purpose of improving the cooling effect is achieved by increasing the contact area between the copper tube and the cooling water. People pay more attention to how to increase the contact area and increase the anti-corrosion zinc block to ensure the reliability of the cooler. However, from the point of view of the use effect, the service life of the seawater cooler is not long, and problems such as end cover corrosion and copper pipe corrosion often occur. The main reason is that there are impurities in the material of the copper end cap that are easily corroded, and it is impossible to accurately judge the time to replace the anti-co...
