Description
Technical Field
[0001] The utility model relates to the technical field of exhaust structures, in particular to an exhaust structure for a kettle. Background Art
[0002] As the automobile industry is growing faster and faster, especially the new energy automobile industry, the development is particularly rapid. Due to the large difference between the management systems of new energy vehicles and traditional vehicles, and the strict noise control and heat conversion requirements for the noise of the vehicle air-conditioning system, various noise solutions and high heat conversion efficiency solutions have been applied, and the corresponding internal exhaust of the thermal management system has become a more important part of the new energy automobile industry.
[0003] Most new energy vehicles will have a system exhaust structure designed in the expansion kettle. The traditional exhaust structure usually has problems such as complex structure and poor reliability. In addition, the internal bubbles cannot be eliminated when the thermal management system is running, which increases the noise of the whole vehicle. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a kettle exhaust structure which can realize internal exhaust of the system, eliminate bubbles in the liquid, and reduce the situation where gas cannot be discharged due to large churning of the liquid level in the chamber.

Since the water inlet pipe increases the flow distance of the liquid, the bubbles will be suspended above the inner surface of the water inlet pipe as the liquid flows. Then the gas will enter the gas-liquid outlet pipe with a part of the liquid and be discharged through the drain pipe. After the remaining liquid flows into the chamber, the original gas in the chamber rises and is discharged outward through the filling pipe, thereby achieving internal exhaust of the system and eliminating bubbles in the liquid. Since the actual liquid outflow from the gas-liquid outlet pipe is relatively small, the situation where the gas cannot be discharged due to the large churning of the liquid surface in the chamber can be reduced.
[0006] Preferably, two groups of liquid infusion tubes are included, and the two groups of liquid infusion tubes are respectively connected and arranged on both sides of the gas-liquid outlet pipes; since the water inlet pipe flows out through two interfaces, the flow of the water inlet pipe will be reduced, and considering the liquid circulation in the chamber, liquid infusion tubes are reserved on both sides of the gas-liquid outlet pipes, thereby ensuring the outlet flow of the water inlet pipe and the circulation of the liquid in the chamber.
[0007] Preferably, the lower kettle body and the upper kettle body are connected by hot plate welding, thereby improving the sealing effect and firmness of the connection between the lower kettle body and the upper kettle body.
[0008] Preferably, the lower kettle body and the upper kettle body are both formed by PP-GF20 plus glass fiber injection molding, thereby improving the corrosion resistance and usage strength of the lower kettle body and the upper kettle body.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: liquid enters from the input end of the water inlet pipe through the system circulation. During the liquid flow process, the liquid carrying bubbles first flows through the inside of the water inlet pipe to the gas-liquid outlet pipes. Since the water inlet pipe increases the flow distance of the liquid, the bubbles will be suspended above the inner surface of the water inlet pipe as the liquid flows. Then, the gas will enter the gas-liquid outlet pipes with a part of the liquid and be discharged through the drain pipe. After that, after the remaining liquid flows into the chamber, the original gas in the chamber rises and is discharged to the outside through the filling pipe, thereby achieving internal exhaust of the system and eliminating bubbles in the liquid. Since the actual liquid outflow from the gas-liquid outlet pipes is relatively small, the situation where the gas cannot be discharged due to the large churning of the liquid level in the chamber can be reduced.

[0021] like Figure 4 As shown, it also includes two groups of liquid replenishing tubes 8, and the two groups of liquid replenishing tubes 8 are connected and arranged on both sides of the gas-liquid two-way outlet pipe 9;
[0022] In this embodiment, liquid enters from the input end of the water inlet pipe 1 through the system circulation. During the flow of the liquid, the liquid carrying the bubbles first flows through the inside of the water inlet pipe 1 to the gas-liquid outlet pipe 9. Since the water inlet pipe 1 increases the flow distance of the liquid, the bubbles will be suspended above the inner surface of the water inlet pipe 1 as the liquid flows. Then, the gas will enter the gas-liquid outlet pipe 9 with a part of the liquid and be discharged through the drain pipe 2. After the remaining liquid flows into the chamber, the original gas in the chamber rises and is discharged to the outside through the filling pipe 4, thereby achieving internal exhaust of the system and eliminating bubbles in the liquid. Since the actual liquid outflow from the gas-liquid outlet pipe 9 is relatively small, the situation where the gas cannot be discharged due to the large churning of the liquid surface in the chamber can be reduced.
[0023] Example 2
[0024] On the basis of Example 1, Figure 1 As shown, in a kettle exhaust structure of the utility model, the lower kettle body 10 and the upper kettle body 11 are connected by hot plate welding;
[0025] like Figure 1As shown, the lower kettle body 10 and the upper kettle body 11 are both formed by PP-GF20 plus glass fiber injection molding;
[0026] like Figure 1 As shown, it also includes a first fixing member 3, a second fixing member 5 and a third fixing member 6, the first fixing member 3 is arranged on the outer side wall of the lower kettle body 10, and the second fixing member 5 and the third fixing member 6 are respectively arranged on the outer side wall of the upper kettle body 11;
[0027] like Figure 1 As shown, it also includes a wire harness fixing ring 7, which is arranged on the outer side wall of the upper kettle body 11;
[0028] In this embodiment, since the water inlet pipe 1 is divided into two interfaces to flow out, the flow of the water inlet pipe 1 will be reduced, and considering the liquid circulation in the chamber, liquid replenishment pipes 8 are reserved on both sides of the gas-liquid outlet pipes 9, respectively. At the same time, this ensures the outlet flow of the water inlet pipe 1 and the liquid circulation in the chamber, thereby improving the connection sealing effect and firmness of the lower kettle body 10 and the upper kettle body 11.
[0029] The utility model discloses an exhaust structure for a kettle. When the kettle is working, liquid enters from the input end of a water inlet pipe 1 through a system circulation. During the flow of the liquid, the liquid carrying the bubbles first flows through the inside of the water inlet pipe 1 to the gas-liquid two-way outlet pipe 9. Since the water inlet pipe 1 increases the flow distance of the liquid, the bubbles will be suspended above the inner surface of the water inlet pipe 1 as the liquid flows. Then, the gas will enter the inside of the gas-liquid two-way outlet pipe 9 along with a part of the liquid and be discharged through the drain pipe 2. After that, after the remaining liquid flows into the chamber, the original gas in the chamber rises and is discharged outwardly through the filling pipe 4, thereby achieving exhaust inside the system and eliminating bubbles in the liquid.
