TECHNICAL FIELD

[0001] The utility model relates to the technical field of kettle structure, in particular to a novel expansion kettle structure. BACKGROUND

[0002] The traditional expansion kettle of the electric vehicle is divided into several cavities in the kettle body to store liquid and slow the flow from the water pipe outlet to the inlet.

[0003] Problems of the traditional expansion kettle structure:

[0004] 1. More noise: Since the water inlet of the kettle is in the cavity part of the liquid level line, the water falls by gravity, and the falling process of the cooling liquid will produce the sound of falling water, which is easy to be transmitted to the cockpit.

[0005] 2. Poor gas-liquid separation effect: Since the water inlet of the kettle is in the cavity part of the liquid level line, the water falls by gravity, and the falling process of the cooling liquid will carry a large amount of air, increasing the air in the kettle body. The water pump outlet is generally connected to the water pump, and the traditional kettle is easy to appear insufficient water supply near the water inlet under the condition of full power operation of the water pump, and produce bubbles. It is easy to let the water pump impeller (cavitation), which will erode the metal surface.

[0006] 3. Traditional expansion layout limitation: The traditional kettle is limited by the partition rib of the cavity, which causes the traditional kettle to be divided into an upper and lower mold form. The limitation of the mold forming process causes the expansion kettle to be horizontally molded, and the kettle shape is relatively flat and round.

[0007] 4. Expansion kettle pipeline connection: The kettle needs to be connected with two pipelines in the system, one is the exhaust hole pipeline in the system, and the other is the water outlet. Too many pipeline connections increase the cost and are easy to leak. Utility model content

[0008] To solve the above technical problems, the utility model provides a novel expansion kettle structure which has better exhaust effect, does not produce new air due to exhaust of the system itself, improves the water vapor separation effect, reduces the connection of the pipeline, reduces the cost and the risk of leakage caused by connection.

[0009] The utility model discloses a novel expansion water pot structure, including lower casing, upper casing, connecting pipe, water inlet and water outlet, and the lower casing and upper casing intercommunication constitute a whole, and the connecting pipe intercommunication is set in the lower casing outside wall lower part, and the water inlet and water outlet are set on the connecting pipe respectively, through the cavity of the original kettle body is isolated, changes one lower casing and upper casing combination's big cavity, and the exhaust effect is better, and the system itself does not exist because of the exhaust and produces the new air condition, because the connecting pipe intercommunication is set in the lower casing outside wall lower part and is located below the liquid level position, and the water flow is relatively quiet, improves the water vapor separation full effect, and the flow section area of cooling liquid from the outlet to the inlet is relatively big, is the whole expansion water pot cavity, and the flow is relatively slow, and the water vapor separation effect is compared to the original expansion water pot structure and has the effect promotion of 30 percent, and the water pot water inlet nearby does not easily appear the water shortage condition under the full power, and the stable pressure reduces the bubble generation, prolongs the water pump life, and does not need the pipeline connection, only uses a connecting pipe to reach the water inlet and outlet, exhaust effect, reduces the connection of pipeline, reduces the cost and the leakage risk of connection.

[0010] Preferably, it further comprises a pressure cover, the lower casing top end is provided with a pressure port, and the pressure cover is installed at the pressure port through screw threads; the convenience of dismounting operation of the pressure cover is improved, and the convenience of maintenance and inspection in the lower casing is improved.

[0011] Preferably, it further comprises a sealing ring, and the sealing ring is installed on the connecting pipe outside wall; by setting the sealing ring, the sealing effect of the connecting pipe and the external manifold is improved.

[0012] Preferably, it further comprises a plurality of groups of first reinforcing ribs and a plurality of groups of second reinforcing ribs, the plurality of groups of first reinforcing ribs are all arranged on the lower casing inside wall, the plurality of groups of second reinforcing ribs are all arranged on the upper casing inside wall, and the positions of the plurality of groups of first reinforcing ribs and the plurality of groups of second reinforcing ribs correspond to each other; by setting the plurality of groups of first reinforcing ribs and the plurality of groups of second reinforcing ribs, the use strength of the kettle structure is improved, and the use reliability is improved.

[0013] Preferably, the lower casing outside wall is provided with a highest liquid level and a lowest liquid level scale; the convenience of measuring the liquid level height in the lower casing is improved.

[0014] Compared with the prior art, the beneficial effects of the utility model are that: through separating the multiple cavities of the original kettle body into one large cavity composed of a lower shell and an upper shell, the exhaust effect is better, and there is no new air generated due to exhaust of the system itself, the water flow is relatively quiet because the connecting pipe is communicated and arranged below the liquid level at the lower part of the outer side wall of the lower shell, the water vapor separation effect is improved by 30% compared with the original expansion water kettle structure, the water shortage situation does not easily occur near the water inlet of the water kettle under full power, the stable pressure reduces bubble generation, prolongs the service life of the water pump, and the water inlet and outlet, exhaust effect are achieved only by one connecting pipe, the connection of the pipeline is reduced, the cost and the leakage risk caused by the connection are reduced.
