Description

Technical Field

[0001] This utility model belongs to the field of new energy mining trucks, specifically relating to an integrated multi-circuit cooling device. Background Technology

[0002] Electric mining dump trucks and hydrogen fuel cell mining dump trucks are both referred to as new energy mining trucks. The main advantages of new energy mining trucks are their environmental performance and lower operating costs compared to traditional mining trucks. New energy mining trucks are technically complex equipment, involving many electric drive components and control elements, resulting in a larger number of pipes and cables.

[0003] For new energy mining trucks, multiple battery packs are typically installed, each with its own cooling circuit. If each circuit is an independent circuit, it would require independent cooling components, a radiator, a water pump, an expansion tank, and piping. This approach involves numerous components, making overall vehicle layout difficult. If multiple circuits are connected in parallel, the entire cooling system includes a large radiator, multiple cooling components, one or two water pumps, several T-junctions, several flow valves, and piping. This approach involves complex piping connections. Because each cooling component corresponds to a different pipe length and resistance, although flow valves can adjust the flow rate of each circuit to achieve consistent cooling across all circuits, achieving this consistency during actual testing is challenging.

[0004] New energy mining trucks have limited overall space, with some areas being cramped, which is not conducive to the installation and layout of larger equipment. Therefore, how to effectively utilize the overall space of the vehicle has become an urgent technical problem to be solved. Utility Model Content

[0027] The integrated multi-loop cooling device includes: an expansion tank 1, an integrated water supply pipe 2, an integrated vent pipe 3, and multiple cooling units 4.

[0028] The expansion tank 1 includes: a tank body 11, a filling port 12, an overflow port 13, a vent 14, and a water inlet 15.

[0030] Overflow port 13 is connected to overflow pipe 17, and overflow pipe 17 is equipped with overflow valve.

[0031] like Figure 3The figure shown is a structural schematic diagram of the integrated water supply pipe 2 in this utility model.

[0032] The integrated water supply pipe 2 includes: a water supply pipe body 21, a water supply pipe inlet 22, and a water supply pipe outlet 23. The water supply pipe inlet 22 is located at the top of the water supply pipe body 21, and multiple water supply pipe outlets 23 are respectively located on both sides and the bottom of the water supply pipe body 21.

[0033] The water supply pipe inlet 22 is connected to the lower part of the water supply port 15 and is connected to the water supply port 15. The water supply pipe outlet 23 is connected to the circulating water pipe 44 of the cooling unit 4 through the water supply pipe 18.

[0034] The number of water supply pipe inlets 22 is the same as the number of cooling units 4. The water supply pipe inlets 22 and water supply pipe outlets 23 are connected to the inner cavity of the water supply pipe body 21. The water supply pipe 18 is a flexible hose.

[0035] like Figure 4 The diagram shown is a structural schematic of the integrated water pipe 3 in this utility model.

[0036] The integrated vent pipe 3 includes: a vent pipe body 31, an air inlet pipe 32, and a fixing plate 33. The fixing plate 33 is connected to the side of the vent pipe body 31 and is provided with an installation through hole 37. The tops of multiple air inlet pipes 32 are connected to the bottom of the vent pipe body 31. The top of the vent pipe body 31 is provided with a vent pipe outlet 34, and the side is provided with multiple air inlets 35. The vent pipe outlet 34 is connected to the air inlet 14 of the expansion tank 1 through an air pipe 16.

[0037] The number of air inlets 32 and air vents 35 is the same as the number of cooling units 4, depending on the number of cooling units 4. Mounting holes 37 are used to fix the integrated air vent 3 in a designated position.

[0038] The outlet at the top of the inner cavity of the vent pipe outlet 34 is conical; multiple air inlets 32 are parallel to each other, and the positioning plate 36 is provided with a positioning through hole. The air inlets 32 are connected in the positioning through hole and fixed by the positioning plate 36.

[0039] Multiple air inlet pipes 32 are connected to water collectors at their bottoms. The water collectors are connected to the water tank body 11 through a return pipe, and a return pump is installed in the return pipe.

[0040] like Figure 5 The diagram shown is a structural schematic of the cooling unit 4 in this utility model.

[0041] The cooling unit 4 includes a cooling component 41, a radiator 42, and a water pump 43. The cooling component 41 and the radiator 42 are connected by a circulating water pipe 44, forming a circulation channel between them. The water pump 43 is installed on the circulating water pipe 44 to provide power for the circulating water for heat dissipation. The top of the cooling component 41 is connected to the bottom of the air inlet pipe 32 through a vent pipe 16, and the top of the radiator 42 is connected to the air inlet 35 of the integrated vent pipe 3 through a vent pipe 16.

[0042] The radiator 42 is equipped with a regulator, an electric fan, and a temperature sensor. The regulator adjusts the speed of the electric fan according to the water temperature signal read by the temperature sensor, thereby adjusting the heat dissipation of the radiator 42 in a timely manner.

[0043] During operation, coolant is injected through the filling port 12 and enters the integrated water supply pipe 2 through the water inlet 15. The coolant is then dispersed into multiple cooling units 4 through the integrated water supply pipe 2. Simultaneously, air / water vapor from the cooling units 4 is collected into the integrated vent pipe 3 through the vent pipe 16 and enters the expansion tank 1. When the coolant reaches the required level in the expansion tank 1, the entire system is filled with coolant. During normal system operation, a circulation loop is formed inside the cooling units 4, transferring the heat generated by the cooling components 41 to the radiator 42 in real time. When the coolant temperature rises, air / water vapor appears inside each loop. At this time, the air / water vapor is collected into the integrated vent pipe 3 through the vent pipe 16 and then enters the expansion tank. 1. The coolant, after removing air bubbles in the expansion tank 1, is then distributed to each cooling unit 4 through the integrated water supply pipe 2. If the pressure exceeds the set pressure of the overflow valve, the pressure is released through the overflow port 13 to protect the interior of the cooling unit 4 from cavitation. This utility model, due to the design of the integrated water supply pipe 2 and the integrated vent pipe 3, allows multiple cooling units 4 to share one expansion tank 1. Compared with multiple independent cooling systems, it saves more space in the new energy vehicle and has the advantages of simple structure and reliable control. At the same time, only the liquid level of one expansion tank 1 needs to be monitored during maintenance. More importantly, the multiple cooling units 4 are independent and unaffected by each other. The speed of the electric fan is adjusted in real time by their respective regulators, which can effectively regulate the heat exchange of the integrated multi-loop cooling device.

[0044] The terminology used in this invention is descriptive and exemplary, and not restrictive. Since this invention can be embodied in various forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
