Description

Technical Field

[0001] This utility model belongs to the technical field of high-efficiency heat exchange devices, and relates to a small high-efficiency heat exchange device, specifically a device that uses circulating cold fluid and hot fluid to exchange heat and generate thermal energy. Background Technology

[0002] Currently, existing heaters require prolonged engine warm-up times and multiple cycles in extremely cold weather (below -40°C), consuming a significant amount of battery power during operation. Furthermore, low temperatures reduce the battery's discharge capacity, impacting the equipment's reliable continuous operation and battery life under certain conditions. Summary of the Invention

[0003] The purpose of this high-efficiency heat exchange device is to provide a high-efficiency heat exchange device for a heater, so as to achieve long-lasting heat preservation in extremely cold weather and improve heat exchange efficiency. The device is mainly composed of pipe (1), core cylinder (2), support plate (3), water inlet (4), water outlet (5), and outer shell (6), etc., and is used for heat exchange between circulating cold fluid and hot fluid.

[0004] The high-efficiency heat exchange device uses a ring-shaped superimposed heat exchange method for its pipes (1). Four rows of pipes (1) are set inside the outer shell (6), with four pipes (1) in each row. The straight pipes are connected to each other by bends. The straight pipes are made of steel pipes with a diameter of 24 mm and a wall thickness of 1 mm and a length of 280 mm. The bends are made of the same type of bends and are bonded with welding agent or butyl waterproof tape to prevent liquid from flowing out. The pipes (1) have a heat exchange area of ​​0.42 m². 2 It features small size, uniform structure, and good thermophysical properties. To prevent the annular pipe (1) from dissipating heat, the first, second, third, and fourth rows of pipes are connected by baffles. The baffles are connected to the outer shell by rails. A support frame is welded between the straight pipe and the outer shell (6), which not only enhances its stability but also facilitates later maintenance and upkeep. This allows for the exchange of cold and hot fluids inside and outside the pipe. To improve the heat exchange efficiency of the cold fluid, the hot fluid is discharged through the tail end of the heat exchange pipe and reheats the cold fluid through the channel between the shells. The exhaust gas is discharged through the flue pipe.

[0005] The high-efficiency heat exchanger uses the same material for its pipes and all types of pipes are of the same size, and is procured uniformly. This is done to save time and costs, facilitate replacement, and reduce the cost and maintenance of the heater.

[0006] By using a high-efficiency heat exchange device for the heater, the engine heating time is reduced, the battery power consumption during the heating process is reduced, the battery capacity is maintained in low-temperature environments, the continuous working time of the equipment is increased, and the reliability of the equipment is improved.

[0010] As shown in the figure: pipe (1), core cylinder (2), support plate (3), water inlet (4), water outlet (5), outer shell (6). Detailed Implementation

[0011] This high-efficiency heat exchanger employs a ring-shaped superimposed heat exchange method, with four rows of four pipes arranged inside the outer casing. Straight pipes are connected to each other using bends. The straight pipes are 280mm long steel pipes with a diameter of 24mm and a wall thickness of 1mm. The bends are purchased from the same type of pipe and are bonded together with welding agent or butyl waterproof tape to prevent liquid leakage. The pipeline has a heat exchange area of ​​0.42m². 2 It features small size, uniform structure, and good thermophysical properties. The first, second, third, and fourth rows of pipes are connected by partitions, and the partitions are connected to the outer shell by rails. A support frame is welded between the straight pipes and the outer shell, which not only enhances its stability but also facilitates later maintenance and repair. It enables the exchange of cold and hot fluids inside and outside the pipes. To improve the heat exchange efficiency of the cold fluid, the hot fluid is discharged through the tail end of the heat exchange pipe and reheats the cold fluid through the channel between the shells. The exhaust gas is discharged through the flue pipe.

[0012] By using a high-efficiency heat exchange device for the heater, the engine heating time is reduced, the battery power consumption during the heating process is reduced, the battery capacity is maintained in low-temperature environments, the continuous working time of the equipment is increased, and the reliability of the equipment is improved.
