Description

Heat exchange device for ship SCR system Technical Field The utility model relates to the technical field of heat exchange devices, in particular to a heat exchange device for a ship SCR system. Background A heat exchange device is an apparatus for transferring heat between two or more fluids (or fluids and solids) with the core objective of achieving efficient transfer of thermal energy while maintaining physical separation of the fluids. The heat exchanger device disclosed by the embodiment of the utility model comprises a heat exchange shell and a heat exchange tube, wherein a partition plate is arranged in the heat exchange shell, the partition plate divides an inner cavity of the heat exchange shell into a first heat exchange cavity and a second heat exchange cavity, the first heat exchange cavity is used for cooling liquid of a battery and/or an engine, the second heat exchange cavity is used for cooling air-conditioning refrigerants, a cooling working medium inlet and a cooling working medium outlet are formed in the heat exchange shell, the heat exchange tube is inserted into the first heat exchange cavity and the second heat exchange cavity, the inlet end of the heat exchange tube is communicated with the cooling working medium inlet, and the outlet end of the heat exchange tube is communicated with the cooling working medium outlet. The scheme of the utility model provides the heat exchanger which can be simultaneously suitable for cooling various components, and solves the technical problems in the prior art. When the device is used, because dead angles in the device are too many, the positions of the partition plates are fixed, the speed of fluid flowing through is uneven, the laminar flow phenomenon caused by the difference of flow rates causes uneven heat exchange process, fluid with low flow rate fully exchanges heat but always accumulates in the device, fluid with high flow rate is discharged out of the device due to insufficient heat exchange, and heat energy loss is caused and needs to be improved. Disclosure of utility model The present utility model is directed to solving the technical problems set forth in the background art. The heat exchange device for the ship SCR system comprises a shell, wherein flange plates are fixedly arranged at two ends of the shell, a sliding groove is formed in the shell, a partition plate is connected in the sliding groove in a sliding mode, a heat exchange tube is connected in the partition plate in a sliding mode, sealing plates are fixedly arranged at two ends of the heat exchange tube, racks are fixedly arranged on the side faces of the sealing plates, gears are connected with the surfaces of the racks in a meshed mode, one end of each gear is fixedly provided with an output end of a motor, and a sealing ring is fixedly arranged between the output end of the motor and the shell. Preferably, the number of the sliding grooves and the partition plates is seven, and the seven groups of the sliding grooves and the partition plates are distributed at equal intervals. Here, spout cooperation division board rotates under the drive of motor, and the division board makes the heat exchange tube more stable.
