Description

Automobile expansion kettle

Technical Field

The utility model belongs to the technical field of auto-parts, especially, relate to an automobile expansion kettle.

Background

The automobile expansion water bottle belongs to a part in the cooling circulation of an automobile engine, when the engine runs, cooling liquid can circulate in a cooling water channel continuously and can flow through the expansion water bottle midway, and if the pressure is too high or the cooling liquid is excessive, redundant gas and the cooling liquid flow out from a bypass water channel of the expansion water bottle, so that the severe consequence of pipe burst caused by too high pressure of a cooling system is avoided. The flow rate of cooling liquid passing through the kettle body in the traditional automobile is about 5L/min, and the requirements of degassing, stable liquid level and no noise can be generally met. And the new forms of energy motorcycle type can let the expansion kettle directly participate in cooling system's circulation in order to reach the purpose of saving the cost, and the coolant liquid velocity of process kettle body can reach 20L/min this moment, and liquid can appear rolling, and is turbid, and a large amount of bubbles in the system can cause the not enough and cave of system spare of system cooling etc.. Therefore, an expansion kettle which can ensure that the liquid level of the system is stable in the operation process, and no turbidity and a large amount of bubbles are brought into the system needs to be developed.

Disclosure of Invention

In order to solve the defects of the prior art, the utility model provides an automobile expansion kettle.

The purpose of the utility model is realized through the following technical scheme:

the automobile expansion kettle comprises an upper cover and a lower cover which are matched with each other, wherein an inlet and an outlet are formed in the lower cover, a drainage channel used for guiding fluid is further arranged in the lower cover, one end of the drainage channel is communicated with the inlet, and the other end of the drainage channel is communicated with the outlet.

Preferably, the cross section of the drainage channel is arranged in an arc shape or a straight shape.

Preferably, the side wall of the drainage channel is provided with exchange holes in a staggered manner.

Preferably, reinforcing ribs are arranged in the upper cover and the lower cover, and the drainage channel is clamped on the reinforcing ribs.

Preferably, the drainage channel is an arc-shaped cover with an opening at the bottom.

Preferably, a connecting bayonet for positioning is arranged on the drainage channel.

Preferably, the upper cover and the lower cover are connected by welding.

Preferably, the radius of the arc of the drainage channel is equivalent to the radius of the inlet and the outlet of the lower cover.

The beneficial effects of the utility model are embodied in: the utility model discloses an expansion kettle makes cooling system in high-speed moving, and partly cooling water can directly form the circulation to the export through importing, and another department's liquid forms the low-speed buffering circulation from drainage channel entering kettle body inside, makes the internal miniature chamber that connects in parallel of forming of kettle, plays the fluid infusion, and the degasification stabilizes the effect of liquid level, has avoided muddy and a large amount of bubbles to bring into the system, has guaranteed the stability of system.

Detailed Description

The technical solution of the present invention is specifically explained below with reference to the accompanying drawings and the embodiment, and the present invention discloses an automobile expansion water bottle, which is shown with reference to fig. 1-4, and comprises an upper cover 1 and a lower cover 2, which are mutually matched, wherein a pressure cover 3 is arranged on the top of the upper cover 1. The upper cover 1 and the lower cover 2 are in hot plate welding fusion connection. And reinforcing ribs 21 are arranged in the upper cover 1 and the lower cover 2 and used for enhancing the bearing pressure of the expansion kettle. The lower cover 2 is provided with an inlet 23 and an outlet 22, and the cooling liquid enters the expansion water kettle through the inlet 23 and flows out through the outlet 22. For avoiding the phenomenon such as rolling, muddy appearing behind the high-speed coolant liquid entering kettle, still be provided with the drainage channel 4 that is used for the fluid direction in the lower cover 2, drainage channel 4's one end and 23 UNICOMs of import, the other end and export 22 UNICOMs. The liquid inlet and outlet radii of the flow-guiding channel 4 are comparable to the radii of the inlet 23 and the outlet 22. In this embodiment, the drainage channel 4 is an arc cover with an opening at the bottom, so that the cross section of the drainage channel is in a semi-arc shape, the structure reduces the molding difficulty of a mold, and meanwhile, the matching of parts and a kettle body can be better completed. On an automobile assembly line, after the kettle is assembled, cooling liquid needs to be filled from a kettle opening, the sectional area of the opening on the side surface of the drainage channel 4 needs to be equal to that of the water inlet and the water outlet, and the cooling liquid is enabled to normally flow into the whole cooling system.

The shape of the drainage channel 4 may be arranged according to the positional relationship between the inlet 23 and the outlet 22 of the kettle. The utility model lists two relations, as shown in fig. 1-2, an angle is arranged between the inlet 23 and the outlet 22, and the cross section of the drainage channel 4 is in a smooth transition shape; when the inlet 23 and the outlet 22 are on the same axis, the cross section of the drainage channel 4 is straight, as shown in fig. 3-4.

The drainage channel 4 can be directly clamped on the reinforcing rib 21 by arranging a clamping groove, and a connecting bayonet 42 for positioning can be further arranged above the drainage channel 4 for further enhancing the connection, and the drainage channel is fixed with the reinforcing rib again through the connecting bayonet 42. Exchange holes 41 are formed in the side wall of the drainage channel 4 in a staggered mode, so that a small parallel cavity is formed inside the kettle body, the cooling liquid entering the kettle body flows in the kettle body through the exchange holes 41 to form parallel circulation flow, the effects of water replenishing and air exchange are achieved, the liquid level is stable, and the problem that a large amount of bubbles are generated in the cooling liquid entering the system subsequently is solved.

Of course, the present invention has many specific embodiments, which are not listed here. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.
