Description

Technical Field

[0001] The utility model relates to the technical field of ship heat exchange, in particular to a heat pump antifreeze heat exchange device for ships in northern cold regions. Background Art

[0002] The ship heating system is a system used to provide hot water for ships, usually consisting of boilers, heaters, pipes and distribution valves. During winter voyages, ships often need to stay in sea ice or cold waters, which causes the ship to require additional energy and fuel to keep warm and running. Therefore, the ship heating system is a very important component.

[0003] The ship's equipment will generate a lot of heat when it is running. If it is not discharged in time, it will cause the equipment to overheat, affect the normal operation of the equipment, and even cause accidents such as fire.

[0004] Existing cooling methods mainly include air cooling and water cooling. The equipment unit is cooled by air cooling, relying on the airflow in the natural environment to take away the heat, and the effect is poor. If the large ship engine is cooled directly by water, this method has a fast cooling speed, but the temperature in the northern cold regions is relatively low. When the cooling water temperature is too low, the ship unit is cooled directly by low-temperature cooling water in the northern cold regions, which can easily cause the high-temperature unit to suddenly come into contact with the low-temperature cooling water, causing the unit pipeline to shrink due to the cold, and the equipment cannot be within the safe operating temperature range. The equipment is shut down, which further leads to an increase in equipment costs. Utility Model Content

[0005] The utility model aims to provide a heat pump antifreeze heat exchange device for ships in northern cold regions, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A heat pump antifreeze heat exchange device for ships in northern cold regions comprises a ship unit, wherein an antifreeze liquid tank is arranged inside the ship unit for absorbing heat and cooling the ship unit, the antifreeze liquid tank contains antifreeze liquid, a first cooling and cooling mechanism for absorbing heat and cooling the antifreeze liquid tank is arranged on one side of the antifreeze liquid tank, and a second cooling and cooling mechanism for absorbing heat and cooling the antifreeze liquid tank is arranged on one side of the antifreeze liquid tank.

[0008] As a preferred solution of the utility model, the first cooling and cooling mechanism includes a cooling water tank, a circulating cooling water pipe is connected to the outer wall of one side of the cooling water tank, the circulating cooling water pipe is arranged in a U-shaped circuitous manner, the outer wall of the circulating cooling water pipe is connected to the outer wall of the antifreeze liquid box, the circulating cooling water pipe is connected to a circulating water pump, and the water outlet of the circulating cooling water pipe is connected to the shell on one side of the cooling water tank.

[0009] As a preferred solution of the utility model, the second cooling mechanism includes a refrigerant bottle, one side of the refrigerant bottle is connected with a circulating refrigerant delivery pipe, the circulating refrigerant delivery pipe is arranged in a U-shape, and the outer wall of the circulating refrigerant delivery pipe is connected to the outer wall of the antifreeze liquid box body.

[0010] As a preferred solution of the utility model, a cooling water inlet pipe is provided through the cooling water tank, and a water inlet of the cooling water inlet pipe is connected to external outdoor river water.

[0011] As a preferred solution of the utility model, a circulation switch valve is provided at the inlet and outlet of the circulating refrigerant delivery pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model uses antifreeze to cool the engine, which avoids the risks and problems caused by directly using cooling water, and can maintain a high-efficiency cooling effect without damaging the equipment. In addition, the solution also mentions a method of cooling the antifreeze by a second cooling mechanism, which is a very advanced technology that can improve the efficiency of the heat pump system and reduce operating costs.

[0014] The heat of the engine of the large ship unit is absorbed by the antifreeze to cool the engine of the unit, and the shutdown phenomenon caused by the continuous high temperature of the engine of the unit is prevented. The outside of the antifreeze tank is cooled by designing a first cooling mechanism, and the antifreeze after absorbing the heat inside the antifreeze tank is further cooled, so that the antifreeze circulates continuously to cool the engine of the unit. The outside of the antifreeze tank is cooled by the second cooling mechanism. When the refrigerant is refrigerated, it changes from liquid to gas, and needs to absorb heat from the outside. The antifreeze tank absorbs heat to increase its body heat, and the antifreeze inside the antifreeze tank is cooled to achieve the effect of cooling the engine of the unit, preventing the large ship unit from continuously running at high temperature and shutting down. The large unit is not cooled directly by cooling water, and the cooling water temperature in the cold northern region is prevented from being too low, which will cause direct damage to the large ship unit and increase equipment costs.
