Embodiment 1

[0024] Such as Figure 1-5 As shown, the water jacket structure of the cylinder block includes the cylinder block, and the water channel cavity a for cooling the cylinder is arranged in the cylinder block, and the water channel cavity a includes the water pump water inlet 1 of the cylinder block, the water channel 2 and the oil cooler cavity 5 of the cylinder block, and the cylinder block The water inlet 6 of the cylinder block is connected to the side of the oil cooler chamber 5; the sand cleaning hole 3 for the sand core of the water channel is also provided at the back of the water channel, and the front part of the water channel 2 is also provided with a reinforcement rib 4 for the cylinder head bolt on the cylinder block, and a water inlet 6 It is connected with the fourth water jacket cylinder in the body water jacket cylinder.

[0025] The water jacket cylinder b of the body is provided at the top of the water channel chamber a, and the air cylinder is matched in the wa...

Embodiment 2

[0029] In this embodiment, the difference from Embodiment 1 is that the cooler chamber 5 forms an angle of 45 degrees with the water channel 2 . The rest of the working principles are the same as in Embodiment 1.

[0030] In addition, in the present invention, the diameters of various water supply holes can be set according to different types of machines.

Abstract

The invention discloses an air cylinder block water jacket structure. The air cylinder block water jacket structure comprises an air cylinder block. A water channel cavity used for cooing an air cylinder is formed in the air cylinder block. The air cylinder block water jacket structure is characterized in that the water channel cavity comprises an air cylinder block water pump water inlet (1), a water channel (2) and an air cylinder block oil cooler cavity (5); the air cylinder block oil cooler cavity (5) side is connected with a water inlet (6) of the air cylinder block; an engine body water jacket cylinder (b) is arranged at the top of the water channel cavity; the air cylinder is arranged in the engine body water jacket cylinder (b) in a matched mode; an upper nozzle (7) which communicates with an air cylinder head is formed in the water channel cavity (a); and the water inlet (6) is connected with a fourth water jacket cylinder in the engine body water jacket cylinder (b).

Description

technical field [0001] The invention relates to an engine cooling mechanism, in particular to a cylinder block water jacket structure. Background technique [0002] The water inlet main pipe on the side of the existing cylinder block water jacket structure is very large, and each cylinder has three water holes going up to the cylinder head, one on the intake side and two on the exhaust side; There is a water inlet hole into the body. The oil cooler is arranged at the end of the main water inlet pipe on the side of the cylinder block. Before the cooling water reaches the oil cooler, it has been diverted from the water jacket of each cylinder. The coolant fluidity at the cooler is poor, the flow rate is small, and the heat exchange efficiency is low. The cooling water passes through the water pump at the front end of the cylinder block, is pressed in from the water inlet at the front end of the cylinder block, flows through the water chamber on the right side of the cylinder ...
