Engine radiators, engine assemblies and vehicles

Abstract

The invention discloses an engine radiator, an engine assembly and a vehicle. The engine radiator comprises an upper water chamber (1), a radiating tube (2) and a lower water chamber (3), a water inlet (4) and a water outlet (8) are located in the same side of the radiator in the width direction, the lower water chamber comprises an upper chamber (31) and a lower chamber (32) which are divided in the vertical direction, a connecting flow passage is formed between the side of the lower chamber along the width direction and the upper chamber, a water outlet is formed in the lower chamber along the other side and is connected with the lower chamber, and the upper chamber is connected with the radiating tube. An engine water pump of a cooling system of the vehicle engine assembly, the water inlet and outlet of the engine radiator and a water inlet and a water outlet of an engine can be arranged in the same side of a longitudinal central line of a vehicle chassis, and accordingly pipelines, fittings and other components across the longitudinal central line are saved, and the mounting structure is optimized; and moreover, cooling liquid uniformly flows in the radiator, the water pressure and flow speed are stable, and the radiating effect is good.

Description

technical field [0001] The invention belongs to the technical field of engine radiators. Background technique [0002] Such as figure 1 As shown, the water inlet 4 and the water outlet 8 of the engine radiator installed in most trucks are usually arranged on both sides along the width direction of the radiator, the water inlet 4 is connected to the upper water chamber, and the water outlet 8 is connected to the lower water chamber. room. In order to ensure that the coolant flows evenly inside the radiator to achieve a stable heat dissipation effect, the water inlet 4 and the water outlet 8 are usually as follows figure 1 The ones shown are arranged diagonally, that is, arranged on opposite sides. join figure 1 The coolant flow direction indicated by the arrow in the figure, in the process of the coolant flowing from the water inlet 4 to the water outlet 8, the coolant in the cooling pipe near the water inlet 4 and the radiator near the water outlet 8 flow through the coo...

Problems solved by technology

Designing these redundant pipelines 11 not only increases the cost and the weight of the vehicle, but also seriously affects the driving reliability of the vehicle, and also creates a burden on the maintenance of the vehicle

Ruo Ru figure 2 As shown, simply arrange the water inlet 4 and the water outlet 8 of the engine radiator on the same side along the width direction of the radiator, then when the coolant flows in the radiator, a large part will flow along the cooling pipe near the water inlet 4. Flowing from the upper water chamber to the lower water chamber, and then flowing out from the water outlet 8, this part of the coolant flows through a short distance, and the water pressure and speed are higher, which causes the coolant in the radiator to flow unevenly and the heat dissipation effect is not good. and unstable
