Embodiment 1

[0045] Please see attached figure 1 and 2 : An integrated expansion kettle, a cooling system and an automobile, including a kettle body 1, the interior of the kettle body 1 is provided with a chamber 2 for containing liquid, and the kettle body 1 is provided with a liquid inlet 1-1 and an outlet Liquid ports 1-2, the kettle body 1 includes a lower kettle body 1a and an upper kettle cover 1b, the shape of the kettle body 1 can be designed according to the installation space, and is not limited to the shape of the solution of the present application. The kettle body 1 is provided with a pressure relief valve 3 and a liquid level sensor 4 .

[0046] For details, please refer to the appendix figure 1 and 2 : The kettle body 1 is also provided with a motor refilling port 5, a degassing liquid inlet 6 and an after-sales switch 7, and the degassing and liquid inlet 6 is connected to the after-sales switch 7 and controls the degassing and liquid inlet 6 through the after-sales swit...

Embodiment 2

[0054] see Figure 7 : A cooling system provided by the technical solution of this embodiment includes a motor cooling circuit, a battery cooling circuit, and the expansion kettle in Embodiment 1.

[0055] To sum up, an integrated expansion kettle and a cooling system are provided by the technical solutions of the first and second embodiments. The expansion kettle integrates the gas-liquid separation function, and is communicated with the liquid inlet and the liquid outlet of the kettle body 1 at the same time. The battery cooling circuit 16 is connected to the motor cooling circuit 17 through the motor liquid replenishment port 5 and the degassing liquid inlet 6. The motor cooling circuit 17 and the battery cooling circuit 16 share an expansion kettle, and the single kettle replaces the double kettle, and there is no need to set up a special external The gas-liquid separator is integrated with the aftermarket switch 7. As a whole, the number of expansion kettles and liquid l...

Embodiment 3

[0058] Please see attached Figure 8 : This embodiment provides an alternative solution for an integrated expansion kettle. Based on Embodiment 1, the fluid direction changing portion 12 may be a bending section, the first opening 13 is located on the inward bending side of the bending section, and the The second opening 14 is located on the outwardly curved side of the bending section, thereby forming a pressure difference between the first opening 13 and the second opening 14, so that the second opening 14 in the cooling liquid flow channel 8 performs liquid discharge, and the first opening 13 performs liquid replenishment .

Abstract

The invention provides an integrated expansion kettle which comprises a kettle body, a cooling liquid flow channel penetrating through a cavity is formed in the kettle body, and at least one gas-liquid separation structure is arranged on the cooling liquid flow channel. Each gas-liquid separation structure comprises a first opening and a second opening, wherein the first opening is formed in the cooling liquid flow channel and used for allowing liquid in the cavity to flow into the cooling liquid flow channel, the second opening is used for allowing the liquid in the cooling liquid flow channel to flow into the cavity, and the pressure intensity of the first opening is larger than that of the second opening. The cooling system comprises a motor cooling loop, a battery cooling loop and the expansion kettle. The automobile comprises the cooling system. According to the gas-liquid separator, separation is conducted in two sections, the gas-liquid separation efficiency is guaranteed, abnormal sound is eliminated, the degassing time of gas-liquid separation is shortened on the whole, heat leakage is reduced, and the temperature difference between a liquid inlet and a liquid outlet can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of expansion kettles, in particular to an integrated expansion kettle, a cooling system and an automobile. Background technique [0002] Expansion kettles are used in many industries, especially in the automotive field. Due to the thermal expansion and contraction of the water in the heating system, when the hot water heats up, the water volume in the system increases. When there is nowhere to accommodate this part of the expansion of the water, the water pressure in the heating system increases, which will affect the normal operation. . The water expansion volume of the system is accommodated by the expansion tank, which can reduce the water pressure fluctuation of the system caused by the expansion of water, and improve the safety and reliability of the system operation. When the system leaks or cools down for some reason, the water level of the expansion tank down to replenish water to the system. In a...
