Description

Technical Field

[0001] The present invention relates to the technical field of thermal management of new energy vehicles, and in particular to a U-shaped flow all-aluminum radiator and a manufacturing method thereof. Background Art

[0002] Due to customer boundary size, piping layout and other reasons, new energy commercial vehicle radiators often cannot adopt the same top-in-bottom longitudinal flow or left-in-right-out cross-flow cooling water layout as traditional diesel and natural gas vehicle radiators, that is, double-sided inlet and outlet I-type flow. Instead, they adopt a top-in-top-out or left-in-left-out single-sided inlet and outlet U-type flow layout. This layout method has higher requirements on the water chamber manufacturing method.

[0003] The existing technology usually uses an integrated water chamber structure, in which the baffle is welded in the middle of the water chamber. However, this design has significant drawbacks: 1. To ensure that the partition and the core do not interfere with each other during assembly, a large safety gap must be reserved during design, which will cause coolant leakage (internal leakage) and cause cross-flow inside the water chamber, thereby reducing heat dissipation performance; 2. The partition is easily missed during the processing, and the existence of the partition cannot be confirmed after welding; 3. If the safety gap is too small, interference is likely to occur during assembly, making it difficult to assemble the water chamber; 4. Compared with the undercut structure of the plastic water chamber and sealing gasket, the all-aluminum welded radiator cannot achieve complete sealing of the two flow channels.

[0004] These problems are particularly prominent in new energy commercial vehicles. When the heat dissipation performance is insufficient, the entire vehicle will experience torque limitation failure, affecting the normal use of the vehicle. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies of the above-mentioned technology and provide a U-shaped flow all-aluminum radiator and a manufacturing method thereof, so as to effectively solve the problem of internal leakage at the partition and improve the heat dissipation performance of the radiator product.

[0006] To achieve the above-mentioned purpose, the U-shaped flow all-aluminum radiator designed in the present invention includes a radiator core, a lower water chamber is installed below the radiator core, and an upper water chamber assembly is installed above the radiator core. The upper water chamber assembly includes a first upper water chamber unit and a second upper water chamber unit. The first upper water chamber unit includes a first inverted U-shaped body, one end of the first inverted U-shaped body is closed, and the other end is provided with a middle partition for closing it. The second upper water chamber unit includes a second inverted U-shaped body, one end of the second inverted U-shaped body is closed, and the other end is an opening that cooperates with one end of the first upper water chamber unit with the middle partition.

[0007] Preferably, a first gap is left between the first water supply chamber unit and the second water supply chamber unit to facilitate welding between the first water supply chamber unit and the second water supply chamber unit.

[0008] Preferably, a second gap is left between the lower bottom edge of the middle partition in the first upper water chamber unit and the lower bottom edge of the first upper water chamber unit to facilitate welding between the middle partition and the radiator core.

[0009] Preferably, a third gap is left between the middle partition in the first upper water chamber unit and the end of the first upper water chamber unit, so as to facilitate welding between the first upper water chamber unit and the second upper water chamber unit, and to facilitate welding between the middle partition and the radiator core.

[0010] Preferably, when the first water supply chamber unit and the second water supply chamber unit are combined into a water supply chamber assembly, the middle partition is located in the middle of the water supply chamber assembly.

[0011] Preferably, the first water supply chamber unit is provided with a water inlet, and the second water supply chamber unit is provided with a water outlet.

[0012] Preferably, both the first water supply chamber unit and the second water supply chamber unit are provided with an air release pipe.

[0013] Preferably, a drain valve is provided at the bottom of the lower water chamber.

[0014] A manufacturing method for the U-shaped flow all-aluminum radiator comprises: first welding the radiator core, then using argon arc welding to weld the lower water chamber, then assembling the first upper water chamber unit on the radiator core, using argon arc welding to weld the first upper water chamber unit and the radiator core, welding the middle partition and the radiator core, then assembling the second upper water chamber unit on the radiator core, using argon arc welding to weld the second upper water chamber unit and the radiator core, and welding the second upper water chamber unit and the first upper water chamber unit.

[0015] Preferably, when the first upper water chamber unit is assembled on the radiator core, a second gap is left between the lower bottom edge of the middle partition in the first upper water chamber unit and the lower bottom edge of the first upper water chamber unit, and a third gap is left between the middle partition in the first upper water chamber unit and the end of the first upper water chamber unit. When the second gap and the third gap both meet the process requirements, argon arc welding is used to weld the first upper water chamber unit and the radiator core, and the middle partition is welded to the radiator core, which effectively eliminates the influence of the weld thickness and water chamber size, and solves the problem of internal leakage of the middle partition. When the second upper water chamber unit is assembled on the radiator core, a first gap is left between the first upper water chamber unit and the second upper water chamber unit. When the first gap meets the process requirements, the second upper water chamber unit and the first upper water chamber unit are welded, which effectively eliminates the influence of the weld thickness and water chamber size.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The design of the split water chamber and the middle partition eliminates internal leakage, improves heat dissipation performance, and avoids vehicle torque limit failure; 2. The water chamber structure is highly versatile and can be highly standardized; 3. Simple manufacturing process, short manufacturing cycle and low cost; 4. Argon arc welding is used to ensure a firm connection between the radiator core, water chamber and middle partition, thus extending the product life; 5. Suitable for radiators of various new energy commercial vehicles. BRIEF DESCRIPTION OF THE DRAWINGS
