Problems solved by technology

[0002] The principle of mercury refrigeration is that the vaporization temperature of mercury is 350°C, and a large amount of heat is absorbed during vaporization to refrigerate. According to the research results, the diesel engine used in the hull is relatively large in power, and the diesel engine needs to be fully cooled. The existing marine diesel engine The combined heat exchanger cannot automatically select the cooling intensity according to the operating power of the diesel engine, and it cannot reuse the cooled mercury. The cooling effect is poor, and it is easy to cause damage to the diesel engine and affect the operation of the hull. Therefore, the design can automatically select cooling A combined heat exchanger for marine diesel engines that can automatically recover the amount of mercury is necessary

Abstract

The invention discloses a combined heat exchanger of a marine diesel engine. The combined heat exchanger comprises a shell, a diesel engine box is fixed to the inner wall of the shell, a propeller is connected to the rear side of the diesel engine box through a bearing, a heat dissipation assembly is fixedly connected to the outer side of the diesel engine box, and a heat exchange instrument is arranged in the diesel engine box. The surface of the diesel engine box is sleeved with a flexible pipe, the heat dissipation assembly comprises an extrusion bin, the extrusion bin has elasticity and is connected to the outer side of the flexible pipe in a sleeving mode, the outer side of the flexible pipe is evenly connected with a plurality of magnetic balls through springs, the magnetic balls are fixedly connected with the extrusion bin, and the extrusion bin is filled with mercury. The left side of the extrusion bin is connected with a first hydraulic ball through a pipeline, the right side of the extrusion bin is connected with a second hydraulic ball through a pipeline, and a first pressing plate is fixed to the inner wall of the first hydraulic ball. The combined heat exchanger has the characteristics that the cooling degree can be automatically selected and the mercury can be automatically recycled.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a combined heat exchanger for a marine diesel engine. Background technique [0002] The principle of mercury refrigeration is that the vaporization temperature of mercury is 350°C, and a large amount of heat is absorbed during vaporization to refrigerate. According to the research results, the diesel engine used in the hull is relatively large in power, and the diesel engine needs to be fully cooled. The existing marine diesel engine The combined heat exchanger cannot automatically select the cooling intensity according to the operating power of the diesel engine, and it cannot reuse the cooled mercury. The cooling effect is poor, and it is easy to cause damage to the diesel engine and affect the operation of the hull. Therefore, the design can automatically select cooling A combined heat exchanger for a marine diesel engine with a certain degree and automatic recovery of m...
