Description

Technical Field

[0001] The utility model relates to the technical field of automobile thermal management systems, and in particular to an integrated heating kettle, a thermal management system and a vehicle. Background Art

[0002] With the rapid development of the new energy vehicle market and the continuous improvement of user demand, the vehicle thermal management system faces huge challenges. The rapid increase in the replacement rate of new energy vehicles has made users more demanding on vehicle endurance and passenger compartment comfort. In order to meet these needs, the thermal management system is gradually developing into a multi-circuit, multi-condition coupled temperature control thermal management system. Its working mode is becoming more and more complex, and the number of components used is rising sharply.

[0003] At the same time, as the space of the vehicle increases, the energy consumption of heating is also increasing, which leads to the scattered layout of vehicle parts, complex pipeline routing, and more brackets, which in turn leads to increased vehicle cost and quality, and increased energy consumption of the vehicle thermal management system. In view of the above problems, designing a small integrated kettle for thermal management has become an urgent need in the industry.

[0004] At present, there are some attempts on the market to solve the problems of difficult layout, increased number of parts and increased energy consumption caused by the complexity of thermal management systems, but they all have obvious shortcomings.

[0005] For example, CN113547957A discloses a thermal management integrated module and thermal management system for electric vehicles. The thermal management integrated module includes an expansion kettle, which is used to accommodate the expansion of the coolant and serves as a carrier of integrated thermal management components; the thermal management components include a battery pump, a motor pump, a battery cooler and a multi-way valve assembly, and the multi-way valve assembly includes a first four-way valve and a second four-way valve; the connecting pipes between the thermal management components are integrated on the expansion kettle, and the expansion kettle is provided with an interface for connecting the thermal management components. When the battery pump, the motor pump, the battery cooler and the control valve assembly are fixedly assembled on the expansion kettle, they are connected to the interface on the expansion kettle at the same time; by integrating some equipment of the thermal management system to form a thermal management integrated module, the connecting pipes between the components in the thermal management system can be reduced. However, the thermal management integrated module has the defects of limited layout space, inconvenient maintenance, high maintenance cost, and inability to achieve rapid heating and temperature rise of the coolant in the kettle.

[0006] Similarly, as disclosed in CN114837796A, an integrated expansion kettle, cooling system and automobile include a kettle body, a coolant flow channel passing through a chamber is arranged inside the kettle body, and at least one group of gas-liquid separation structures are arranged on the coolant flow channel, each group of gas-liquid separation structures includes a first opening arranged on the coolant flow channel for the liquid in the chamber to flow into the coolant flow channel and a second opening for the liquid in the coolant flow channel to flow into the chamber, and the pressure at the first opening is greater than the pressure at the second opening. The integrated expansion kettle is separated into two sections, which reduces abnormal noise and heat leakage. However, the internal partition structure of the kettle is complex, the cost is high, the structure is flat, and it does not have integration capabilities, and it cannot adapt to the requirements of complex vehicle models. At the same time, it is also impossible to achieve rapid heating and temperature rise of the coolant in the kettle, that is, an external electric heater needs to be connected to increase the circuit temperature, which not only makes the circuit lengthy, but also leads to increased heat exchange losses.

DETAILED DESCRIPTION

[0033] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0034] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0035] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. Example

[0036] like Figure 1 As shown, an integrated heating kettle comprises a kettle body 1, on which a heating component 2 and a driving component 3 are mounted. The heating component 2 can heat the liquid in the flow channel in the kettle body 1, and the driving component 3 is connected to the flow channel in the kettle body 1 to drive the liquid in the flow channel to flow.

[0037] By directly arranging a heating component and a driving component on the kettle body, when the coolant in the kettle body needs to be heated, the coolant in the flow channel in the kettle body can be directly heated by the heating component, and the coolant is driven to flow by the driving component, so that the coolant in the kettle body is quickly heated up and circulated. This not only effectively reduces the problem of numerous parts caused by external heating components, but also reduces the difficulty of spatial layout, and also effectively shortens the circulation distance and time of the coolant, reduces heat loss and system internal resistance, thereby effectively reducing heating energy consumption, simplifying the overall vehicle layout, and improving user experience.

[0038] In some embodiments, the kettle body 1 includes a lower bottle body 11 and an upper cover 12 covering the lower bottle body 11 , and the upper cover 12 is provided with a first mounting hole 13 for mounting the heating component 2 .

[0039] In some embodiments, in order to ensure the sealing performance of the heating component and the upper cover, a sealing ring 4 is provided at the first mounting hole 13 so that the heating component 2 and the upper cover 12 are in sealing cooperation.

[0040] In some embodiments, in order to ensure the stability of the assembly of the heating component and the upper cover, a connector 5 is used to assemble and fix the heating component 2 and the upper cover 12 together.

[0041] Exemplarily, the heating component 2 is a small electric heater, which has a mounting portion and a heating resistance wire arranged below the mounting portion, wherein the mounting portion is sealed with the upper cover 12 through a sealing ring 4, and is assembled and fixed with the upper cover 12 through a connecting member 5, and the heating resistance wire passes through the first mounting hole 13 and is located in the flow channel in the kettle body 1, so that when the coolant in the kettle body 1 needs to be heated, the small electric heater is energized, and the heating resistance wire heats the coolant in the flow channel.

[0042] In the above embodiment, by directly integrating a micro electric heating component inside the kettle body and heating the coolant directly in the flow channel of the kettle, it is estimated that the cooling pipeline will be reduced by about 2m, effectively reducing the system flow resistance, reducing the heat exchange loss of the whole vehicle, and improving the vehicle's endurance.

[0043] Exemplarily, the connecting member 5 is a bolt, and an embedded nut is provided on the upper cover 12, so that the small electric heater is directly assembled and fixed on the nut by bolts. And when the small electric heater is damaged, it can be directly disassembled and replaced with a new small electric heater, which not only improves the replacement efficiency but also reduces the maintenance cost.

[0044] In some embodiments, a second mounting hole 14 for mounting the driving component 3 is provided on the lower bottle body 11 .

[0045] Exemplarily, the driving component 3 drives a water pump.

[0046] In some embodiments, in order to ensure the stability of the assembly between the driving component and the lower bottle body, a sealing ring 4 is provided at the second mounting hole 14 so that the driving component 3 and the lower bottle body 11 are in a sealed fit.

[0047] Exemplarily, the sealing ring 4 is an O-ring.

[0048] In some embodiments, in order to ensure the stability of the assembly of the driving component and the lower bottle body, a connecting member 5 is used to assemble and fix the driving component 3 and the lower bottle body 11 together.

[0049] Among them, an embedded nut is provided on the lower bottle body 11, so that the driving component 3 is directly assembled and fixed on the nut by bolts, and is fixed by bolts. When the driving component 3 is damaged, it can be directly disassembled and replaced with a new driving component 3, which not only improves the replacement efficiency but also reduces the maintenance cost.

[0050] In some embodiments, in order to facilitate the filling of coolant, a filling port 15 for filling coolant into the kettle body 1 is provided on the upper cover 12. At the same time, in order to ensure the sealing of the filling port and prevent leakage of coolant, a pressure cap 6 is screwed on the filling port 15, thereby tightening the pressure cap 6 on the upper cover 12.

[0051] In some embodiments, an overflow port 16 is further provided on the upper cover 12 , so that the gas in the flow channel is discharged through the overflow port 16 .

[0052] In some embodiments, a water inlet 17 and a water outlet 18 are further provided on the lower bottle body 11 .

[0053] In some embodiments, a thermal management system is also provided, comprising the integrated heating kettle in any of the above embodiments.

[0054] In some embodiments, a vehicle is also provided, comprising the thermal management system in any of the above embodiments.

[0055] like Figure 1 and Figure 2 As shown, the thermal management system in the above embodiment. In actual operation, when the passenger compartment has a heating demand or the battery has a heating demand, and the temperature sensor T3 detects that the coolant temperature in the circuit is less than 10°C, the driving component 3 drives the coolant in the circuit to flow, and the coolant flows into the kettle body 1 through the water inlet 17 on the lower bottle body 11. After the driving component 3 works for 1 minute, the heating component 2 inside the kettle body 1 starts to work to ensure that the heat exchange starts only when the fluid is convective to avoid heat loss. The resistance wire of the heating component 2 convects and exchanges heat with the coolant circulating in the flow channel. After the coolant is heated, it flows out from the water outlet 18 at the bottom of the lower bottle body 11. After flowing out, the coolant flows to the battery and the HVAC heater core for heat exchange. After the heat exchange, the coolant temperature decreases and flows into the radiator after merging. At this time, if the temperature sensor T1 feedback temperature is less than 40°C, the cooling fan does not work. The coolant continues to circulate, continues to heat the battery and the passenger compartment, and the gas in the circuit is discharged through the overflow port 16. When the temperature sensor T3 detects that the coolant temperature in the circuit is greater than 80°C, the heating component 2 stops working, and the residual heat of the battery is brought out through the coolant to directly exchange heat with the HVAC heater core to heat the passenger compartment. At this time, if the temperature detected by the temperature sensor T1 is greater than 40°C, the cooling fan starts working and transfers excess heat to the outside of the vehicle through the low-temperature radiator to ensure that the battery is not overheated. At this time, if the temperature detected by the temperature sensor T1 is less than 40°, the cooling fan still does not work to reduce heat loss and ensure the heating effect of the passenger compartment. At the same time, the heating power of the electric heater can be adjusted in real time through the feedback temperature of the temperature sensor T1 to avoid waste caused by excessive redundant heat in the circuit. The integrated kettle of the utility model effectively solves the pain points of the difficulty of cold starting of new energy vehicles in winter and insufficient heating of the passenger compartment.

[0056] As mentioned above, the thermal management system of the utility model realizes rapid heating and temperature rise of the coolant in the kettle by integrating the heating component, reduces the cooling pipeline required for the series flow between the electric heater and the kettle, effectively reduces the system flow resistance, and reduces the heat exchange loss of the whole vehicle. The drive water pump is integrated simultaneously, and the water pump is directly connected in series in the loop, reducing the inlet and outlet connecting pipes of the external water pump. The heating component is a small heater that uses spiral resistance wire for heating, which has a simple structure and low cost. At the same time, the performance can be expanded by changing the length of the resistance wire, which is compatible with the heating needs of various types of vehicles.

[0057] In summary, the integrated heating kettle of the utility model directly sets a heating component and a driving component on the kettle body, so that when the coolant in the kettle body needs to be heated, the coolant in the flow channel in the kettle body can be directly heated by the heating component, and the coolant is driven to flow by the driving component, so that the coolant in the kettle body is quickly heated and circulated, which not only effectively reduces the problem of numerous parts caused by external heating components, but also reduces the difficulty of spatial layout, and effectively shortens the circulation distance and time of the coolant, reduces heat loss and system internal resistance, thereby effectively reducing heating energy consumption, simplifying the layout of the whole vehicle, and improving user experience. It solves the problems of difficult layout, numerous parts and high energy consumption of the existing thermal management system. It has the advantages of simple structure, low cost and high efficiency, and has promotion and application value in the field of automotive thermal management system technology.

[0058] The above embodiments are merely illustrative of the principles and effects of the present utility model, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
