DETAILED DESCRIPTION

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0043] like Figures 1 to 6 According to the kettle 11 of the embodiment of the present invention, the kettle 11 includes a kettle body 111, and the kettle body 111 has a first cavity 1101 and a second cavity 1102. The first cavity 1101 and the second cavity 1102 can be used to contain liquid, so as to provide liquid replenishment or degassing to the circulation system through the kettle 11, so that the circulation system can operate stably. The first cavity 1101 and the second cavity 1102 are arranged in the kettle body 111, and are separated from each other and not connected. That is, in the kettle body 111, the first cavity 1101 and the second cavity 1102 are separated from each other, and the liquid in the first cavity 1101 and the liquid in the second cavity 1102 are independent of each other and do not circulate with each other.

[0044] The kettle 11 according to the embodiment of the present invention has multiple independent chambers, which can provide functions such as liquid replenishment and degassing for the circulation system in the thermal management module 100, can meet the stable circulation of liquids in different circulation loops, and improve the stability of the circulation system having the kettle 11. At the same time, the chambers that provide functions such as liquid replenishment for multiple circulation loops are integrated into one kettle, which can improve the integration and space utilization, reduce space occupancy while ensuring performance, and ensure the stability of the system.

[0045] Of course, the present invention is mainly described as having a first cavity 1101 and a second cavity 1102 in the kettle 11, but this does not mean that the kettle 11 in the present invention can have only two cavities. The kettle 11 in the present invention can also have more than three cavities. For example, the kettle 11 in the present invention can have multiple first cavities 1101 or multiple second cavities 1102. The kettle 11 of the present invention can also have a third cavity.

[0046] The first cavity 1101 and the second cavity 1102 in the present invention are arranged in the kettle body 111 and are separated from each other and not connected, which means that the first cavity 1101 and the second cavity 1102 are not connected inside the kettle body 111, but outside the kettle body 111, the first cavity 1101 and the second cavity 1102 can be connected through other structures, or can be completely isolated. For example, the first cavity 1101 can have a first interface, the second cavity 1102 can have a second interface, and the first interface and the second interface can be connected. Although the first interface and the second interface are connected, their connecting structure is not located inside the kettle body 111, and the first cavity 1101 and the second cavity 1102 are not connected to each other inside the kettle body 111, and therefore, they are also within the protection scope of the present invention.

[0047] Of course, in some embodiments of the present invention, the first cavity 1101 and the second cavity 1102 of the kettle body 111 are completely disconnected, that is, the first cavity 1101 and the second cavity 1102 are not connected inside the kettle body 111 and are also not connected outside the kettle body 111.

[0048] The kettle body 111 of the present invention can be assembled in different ways, wherein the kettle 11 can be provided with an outer shell and a partition (such as a partition), and the first cavity 1101 and the second cavity 1102 are divided inside the outer shell by the partition, wherein the partition completely separates the first cavity 1101 and the second cavity 1102, that is, the partition is not provided with a through hole connecting the first cavity 1101 and the second cavity 1102; the kettle 11 can also be divided into three parts, wherein the first part and the second part respectively form the first cavity 1101 and the second cavity 1102 with the third part. Of course, the kettle body 111 can also be formed in other ways in the present invention, and these are all within the protection scope of the present invention.

[0049] The present invention is mainly explained by taking the method of connecting the upper and lower shells 1111 to form the kettle body 111, and forming the first cavity 1101 and the second cavity 1102 in the kettle body 111 as an example, but this is not a limitation of the protection scope of the present invention.

[0050] like Figure 4In some embodiments of the present invention, the kettle body 111 includes: a lower shell 1111 and an upper shell 1112, the upper shell 1112 and the lower shell 1111 are butted up and down, and a first cavity 1101 and a second cavity 1102 are formed between the upper shell 1112 and the lower shell 1111. The upper shell 1112 can be configured to include a first part and a second part, and the lower shell 1111 can be configured to include a third part and a fourth part. When the upper shell 1112 and the lower shell 1111 are butted, the first part and the third part can be butted to form a closed first cavity 1101, and the second part and the fourth part can be butted to form a closed second cavity 1102, so that the upper shell 1112 and the lower shell 1111 can form a first cavity 1101 and a second cavity 1102 separated from each other, simplifying the structure and molding method of the kettle body 111, and reducing the generation and manufacturing cost of the kettle body 111. The upper shell 1112 and the lower shell 1111 can be configured to be connected by welding.

[0051] Among them, Figure 4 As shown, the lower shell 1111 is provided with a first groove 1103 and a second groove 1104, which are arranged flat in the lower shell 1111, and the opening of the first groove 1103 and the opening of the second groove 1104 can be arranged side by side, and when the upper shell 1112 is covered on the lower shell 1111, the first groove 1103 and the second groove 1104 can be covered at the same time, so that the upper shell 1112 is covered on the lower shell 1111 to construct the first cavity 1101 and the second cavity 1102. The first cavity 1101 and the second cavity 1102 can be constructed by covering the first groove 1103 and the second groove 1104 with an upper shell 1112, which facilitates the molding of the upper shell 1112, the molding of the lower shell 1111, and the molding of the kettle body 111, thereby improving the molding efficiency of the kettle body 111.

[0052] In addition, in the thermal management module 100 having the kettle 11, a water side component 10 and a refrigerant side component 20 may be included, wherein the water side component 10 may include a flow channel plate, through which a water flow channel may be formed, so that the water flow pipeline may be integrated into the flow channel plate, thereby improving the integration of the water side component 10. The flow channel plate may include a bottom plate 1113 and a plate body 12, the bottom plate 1113 and the plate body 12 are stacked, and a water channel is formed between the bottom plate 1113 and the plate body 12.

[0053] like Figure 4In some embodiments of the present invention, the kettle body 111 further includes: a bottom plate 1113, the bottom plate 1113 is connected to or integrally formed with the lower shell 1111, and the bottom plate 1113 is used to cooperate with the plate body 12 to construct a flow channel plate with a water channel. In other words, the flow channel plate is constructed by the kettle body 111 and the plate body 12, so that a part of the flow channel plate can be integrated with the kettle body 111, and the structure of the water side component 10 can be simplified.

[0054] In combination with the above embodiments, Figure 4 The combination of the kettle 11 and the flow channel plate is formed by assembling the upper shell 1112, the lower shell 1111 and the plate body 12 together. The upper shell 1112 and the lower shell 1111 can be welded together, and the bottom plate 1113 on the lower shell 1111 can be welded together with the plate body 12, so as to construct a combined structure of the kettle 11 plus the flow channel plate, which can further improve the integration of the water side component 10.

[0055] In addition, if Figure 3 and Figure 4 At least one port 1114 may be provided on the bottom plate 1113, and an external pipe may be connected through the at least one port 1114. The port 1114 may be connected to the first cavity 1101 or the second cavity 1102 in the kettle 11, or may be connected to the water flow channel in the flow channel plate.

[0056] like Figure 2 and Figure 6 In some embodiments of the present invention, the kettle 11 further includes: a liquid level sensor 112, which is mounted on the kettle body 111 and configured to detect the liquid levels in the first cavity 1101 and the second cavity 1102. The liquid level in the kettle 11 can be detected by the liquid level sensor 112, so that the liquid level in the kettle 11 can be checked in time, thereby improving the working stability of the kettle 11.

[0057] Among them, the liquid level sensor 112 can be set corresponding to the first cavity 1101 and the second cavity 1102, or one liquid level sensor 112 can be set to detect the liquid level in the first cavity 1101 and the second cavity 1102, wherein the liquid level sensor 112 can be a float type, a float ball type, or a static pressure type, etc. In addition, the first cavity 1101 can be set with one liquid level sensor 112, or two or more liquid level sensors 112 can be set correspondingly; similarly, the second cavity 1102 can be set with one liquid level sensor 112, or two or more liquid level sensors 112 can be set correspondingly.

[0058] In order to facilitate the external connection of the liquid level sensor 112 to the controller, the liquid level sensor 112 has an electrical plug for an external wiring harness, and the electrical plug is configured to be plugged in and out of the external wiring harness plug in the up-down direction. The electrical plug can be plugged in and out in the up-down direction to achieve electrical connection and disconnection between the liquid level sensor 112 and the controller, thereby facilitating the connection and separation of the kettle 11 from other components, and facilitating the assembly, maintenance, and disassembly of the water side component 10 or the thermal management module 100.

[0059] Optionally, the liquid level sensor 112 may be installed from top to bottom on the kettle body 111. This can facilitate the installation of the liquid level sensor 112, improve the stability and installation efficiency of the liquid level sensor 112, and improve the maintenance efficiency of the liquid level sensor 112.

[0060] In addition, the first cavity 1101 and the second cavity 1102 can share a liquid level sensor 112. Therefore, the liquid levels in the first cavity 1101 and the second cavity 1102 can be detected by a liquid level sensor 112, which effectively simplifies the structure of liquid level monitoring and improves the efficiency of liquid level monitoring. Moreover, the simultaneous detection of the first cavity 1101 and the second cavity 1102 by a liquid level sensor 112 can avoid the problem of detection error caused by the tilt of the kettle 11, effectively improve the accuracy and stability of the detection result, and avoid misjudgment.

[0061] like Figure 2 and Figure 6 The present invention adopts a float type liquid level detection method, wherein the kettle 11 further includes a first float 1131, a first trigger 1141, a second float 1132 and a second trigger 1142. The first float 1131 can be floated in the first cavity 1101, the first trigger 1141 is arranged on the first float 1131, the second float 1132 can be floated in the second cavity 1102, and the second trigger 1142 is arranged on the second float 1132. The first trigger 1141 can rise and fall according to the liquid level in the first cavity 1101, and the first trigger 1141 can cooperate with a liquid level sensor 112 to realize liquid level monitoring in the first cavity 1101. At the same time, the second trigger 1142 can follow the rise and fall of the liquid level in the second cavity 1102, and the second trigger 1142 can cooperate with a liquid level sensor 112 to realize liquid level detection in the second cavity 1102. The liquid level sensor 112 corresponding to the first trigger component 1141 and the liquid level sensor 112 corresponding to the second trigger component 1142 may be the same liquid level sensor 112 or different liquid level sensors 112 .

[0062] The first trigger member 1141 and the second trigger member 1142 are configured to cooperate with the liquid level sensor 112 to monitor the liquid level in the first cavity 1101 and the second cavity 1102. The first trigger member 1141 and the second trigger member 1142 can be configured to cooperate with the same liquid level sensor 112, or the first trigger member 1141 and the second trigger member 1142 can also be configured to cooperate with different liquid level sensors 112. Thus, the liquid level of the first cavity 1101 and the second cavity 1102 can be monitored by the liquid level sensor 112. When the first trigger member 1141 and the second trigger member 1142 can be configured to cooperate with the same liquid level sensor 112, the structure of the kettle 11 is simplified, the efficiency of assembly and maintenance is improved, and the operating stability of the thermal management module 100 having the kettle 11 can be improved.

[0063] In addition, in combination with the above-mentioned embodiments, a stop structure may be provided in the kettle body to limit the first float 1131 and / or the second float 1132. For example, a stop structure may be provided in the first cavity 1101 to limit the range of the first float 1131 floating up and down; a stop structure may also be provided in the second cavity 1102 to limit the range of the second float 1132 floating up and down. The stop structure may have different forms. For example, for the stop of the first float 1131, two stop structures spaced apart from each other may be provided, and at least a portion of the first float 1131 may be provided between the two stop structures, thereby limiting the first float 1131.

[0064] In addition, in combination with the above-mentioned embodiment, the kettle body 111 includes a lower shell 1111 and an upper shell 1112, the upper shell 1112 and the lower shell 1111 are butted up and down, and a first cavity 1101 and a second cavity 1102 are formed between the upper shell 1112 and the lower shell 1111, and stop structures are respectively provided on the upper shell 1112 and the lower shell 1111, for limiting the floating range of the first float 1131 and the second float 1132. By providing the stop structures on the lower shell 1111 and the upper shell 1112, the first float 1131 and the second float 1132 can be limited, and at the same time, the assembly of the kettle can be facilitated, the assembly and maintenance of the kettle can be simplified, and the cost can be reduced.

[0065] In addition, in order to improve the accuracy of water level monitoring, a guide structure for the float can also be provided in the kettle body. In some embodiments of the present invention, at least one of the first float 1131 and the second float 1132 is provided with a rib, and a slot structure is provided in the kettle body 111. The rib and the slot structure cooperate to form a slide rail to guide the float to float up and down, so that the float is not easily stuck and the sensing accuracy is increased.

[0066] In combination with the above-mentioned embodiments, the liquid level sensor 112 is arranged between the first cavity 1101 and the second cavity 1102 , and the first float 1131 is arranged in the first cavity 1101 close to the liquid level sensor 112 , and the second float 1132 is arranged in the second cavity 1102 close to the liquid level sensor 112 .

[0067] In order to further improve the monitoring effect of the liquid level in the first cavity 1101 and the second cavity 1102 and simplify the structure of the kettle 11, the liquid level sensor 112 can be arranged between the first cavity 1101 and the second cavity 1102. Thus, the detection efficiency and effect of the liquid level in the first cavity 1101 and the second cavity 1102 can be improved.

[0068] In addition, if Figure 6 , a housing space 1105 is further provided in the kettle body 111, and at least a part of the liquid level sensor 112 is installed in the housing space 1105. The liquid level sensor 112 can stably detect the liquid level in the first cavity 1101 and the second cavity 1102, and the detection accuracy can be improved. The housing space 1105 can be provided between the first cavity 1101 and the second cavity 1102, or can be provided at other positions on the kettle body 111. Of course, the housing space 1105 can also be omitted, and the liquid level sensor 112 can be provided outside the kettle body.

[0069] Among them, the accommodating space 1105 has an installation port 1106, and the liquid level sensor 112 can be inserted into the accommodating space 1105 through the installation port 1106. A groove body 1107 is provided on the top surface of the kettle body 111. The installation port 1106 is located between the groove body 1107 and the accommodating space 1105, and connects the groove body 1107 and the accommodating space 1105. The width dimension of the groove body 1107 can be set to be larger than the width dimension of the accommodating space 1105. A part of the liquid level sensor 112 is inserted into the accommodating space 1105 through the installation port 1106, and the wiring socket of the liquid level sensor 112 is located in the groove body 1107 to facilitate the external wiring harness.

[0070] Optionally, the accommodating space 1105 is provided at the partition between the first cavity 1101 and the second cavity 1102. The liquid level sensor 112 is provided in the accommodating space 1105, which can conveniently detect the liquid levels of the first cavity 1101 and the second cavity 1102, improve the detection accuracy of the liquid level sensor 112, thereby timely understanding the liquid level in the kettle, timely discovering faults, and improving the stability of the circulation system.

[0071] Optionally, the accommodating space 1105 is separated from and not communicated with the first cavity 1101 and the second cavity 1102. This can reduce water leakage points and avoid water leakage, thereby ensuring the stability and safety of the system and avoiding potential safety hazards caused by water leakage.

[0072] Optionally, the accommodating space 1105 is arranged in the middle of the kettle, so that the accuracy of liquid level detection can be further improved, and when the kettle is tilted, the liquid level can be calibrated by detecting the liquid levels of the first cavity and the second cavity to avoid detection errors.

[0073] Optionally, a leaking hole is provided at the bottom of the accommodating space 1105. The leaking hole can timely drain the water that enters the accommodating space 1105, thereby preventing moisture from accumulating in the accommodating space 1105 and affecting the detection of the liquid level sensor, and also preventing bacteria from growing in the accommodating space 1105 or affecting the service life of the kettle. In addition, since the water in the accommodating space 1105 can be drained in time, water accumulation and freezing in winter can be avoided.

[0074] The liquid level sensor 112 is a switch type Hall element. The first trigger member 1141 and the second trigger member 1142 can be magnetic members. The up and down floating of the first trigger member 1141 and the second trigger member 1142 can change the magnetic field around them, thereby realizing the detection of the liquid level. The liquid level detection is performed by using magnetic changes, and a non-contact detection method is adopted, which reduces the leakage points on the kettle 11, improves the stability of the kettle 11, and reduces the possibility of leakage.

[0075] like Figures 3 to 6 According to the embodiment of the present invention, the water side component 10 includes: a plate body 12; according to the aforementioned kettle 11, the kettle 11 is installed on the plate body 12. The water side component 10 includes the aforementioned kettle 11, and the kettle 11 can be used to provide liquid replenishment and degassing for one or more circulation paths, which can effectively improve the stability of the water side component 10 and ensure that the water side component 10 can operate stably.

[0076] The kettle 11 is stacked on the plate 12. The plate 12 is provided with a flow channel, the bottom plate 1113 of the kettle 11 covers the flow channel, and a water channel is constructed between the kettle 11 and the plate 12. The kettle 11 and the plate 12 cooperate to form a water channel, which can simplify the structure of the water side component 10, improve the molding efficiency of the water side component 10, and facilitate the maintenance of the water side component 10.

[0077] In addition, if Figure 7The present invention also provides a thermal management module 100, comprising: a water side component 10 according to the aforementioned thermal management module 100; a refrigerant side component 20, the refrigerant side component 20 being connected to the water side component 10. The refrigerant side component 20 has a refrigerant flow channel, and is suitable for temperature regulation by phase change of the refrigerant, and the refrigerant side component 20 cooperates with the water side component 10 for heat exchange.
