Description

Technical Field

[0001] This application belongs to the field of electrical assembly technology, specifically relating to a heater integrated module. Background Technology

[0002] For example, in new energy vehicles, components such as compressors and electric heaters are usually driven by high-voltage platforms. Each component has its own wiring harness connectors that connect to the high-voltage lines, resulting in a complex layout, numerous connection processes, and a high risk of errors. This leads to high overall costs and low space utilization. In addition, the independent design of compressors and heaters involves their own power control modules, PCBAs, sensors, low-voltage power processing modules, and connectors, which also increases costs. To improve the above situation, a modular design scheme integrating compressors and heaters is proposed.

[0003] However, this solution still has problems that need to be solved. One key issue is how to better integrate the temperature detection unit of the heater into the module. For example, some solutions place the NTC thermistor on the PCBA, which is only suitable for temperature acquisition scenarios where the location is fixed and the distance between the acquisition point and the PCB is the same.

[0004] This approach would be detrimental to the idea of ​​improving space utilization through integrated modules. The purpose of this application is to provide a heater integrated module that reduces the complexity of each component during product assembly, improves assembly efficiency, and provides a better way to integrate the temperature detection unit into the integrated module.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] like Figures 1-6 As shown, this application provides a heater integrated module, including:

[0033] The control module 1 and the heater housing 2 have a mounting space 4 for temperature detection between them; and

[0034] At least one temperature detection unit 3 is provided. The temperature detection unit 3 includes an NTC thermistor 31, an independent PCB board 32, and a connection structure 33. The independent PCB board 32 is located in the installation space 4. The NTC thermistor 31 is disposed on the independent PCB board 32 on the side close to the heater housing 2. One end of the connection structure 33 is connected to the independent PCB board 32, and the other end is connected to the control module 1. The NTC thermistor 31 is electrically connected to the control module 1 through the independent PCB board 32 and the connection structure 33 in sequence.

[0035] In some embodiments, the control module described above can be a control module shared by the compressor and the heater. The heater integrated module provided in this application can also be referred to as a compressor and heater integrated module.

[0036] It should be understood that the control module 1 can be a PCBA assembly with a control module chip, and the connection structure 33 forms an electrical connection with the control module 1 through the circuit on the PCBA board. The mounting space 4 is actually the space between the PCBA board and the heater housing 2, and the interior of the heater housing 2 is a liquid containment space and a flow channel. Optionally, a heating device is provided on the side of the heater housing 2 facing away from the PCBA. The heating device can be a thin film, thick film, or other form of heating element.

[0037] Optionally, the connection structure 33 is soldered to the wiring point of the independent PCB board 32, and the two ends of the NTC thermistor 31 are connected to the corresponding wiring point through the copper plating layer printed inside the independent PCB board 32.

[0038] Furthermore, in this embodiment, the independent PCB board 32 of the temperature detection unit 3 is only used to carry the NTC thermistor 31 of the temperature detection unit 3. In other words, one independent PCB board 32 corresponds to one NTC thermistor 31. When different temperature detection units 3 are at different distances from the PCBA, by adjusting the length of the connection structure 33 of the access circuit, the temperature detection unit 3 can be flexibly installed in most positions in the installation space, thereby improving the spatial range of temperature detection.

[0039] This application creates an independent temperature detection unit by placing the NTC thermistor in the temperature detection unit on a separate PCB board, eliminating the need for installation on the control module motherboard. This increases the flexibility and adaptability of temperature detection unit installation, allowing it to be installed at different detection points as needed. The installation of multiple temperature detection units does not affect each other, improving the convenience of product assembly and making the integration of the module more feasible.

[0040] In some embodiments, the heater housing 2 is provided with a mounting base 21 corresponding to the temperature detection unit 3, and the mounting base 21 has a receiving portion 211 and a mounting portion 212;

[0041] The independent PCB board 32 is fixedly connected to the mounting base 21 via the mounting part 212. The receiving part 211, the heater housing 2, and the independent PCB board 32 form a receiving space, in which the NTC thermistor 31 is located. The receiving space is filled with thermally conductive putty. Optionally, the receiving space is filled with thermally conductive putty, and the NTC thermistor 31 is placed in this space to fully contact the thermally conductive putty, thereby improving the efficiency and accuracy of temperature acquisition.

[0042] In some embodiments, such as Figure 4-7 As shown, the mounting base 21 has a first contact surface and a second contact surface. The first contact surface contacts the independent PCB board 32, and the second contact surface is welded to the heater housing and adheres to the surface of the heater housing. It should be understood that the first contact surface is located on the side of the mounting base 21 closer to the independent PCB board 32, and the second contact surface is located on the side of the mounting base 21 closer to the independent heater housing 2 board 32.

[0043] Optionally, the connection structure 33 can be a pin type, a fisheye pin type, or a wire harness + connector type.

[0044] Specifically, such as Figure 1 and Figure 4As shown, in some embodiments, the connection structure 33 includes pins 331, and the control module is provided with a first connector 11 corresponding to the pins 331. The pins 331 are connected to the control module 1 through the first connector 11. Optionally, the connection structure 33 includes two pins 331, which correspond to the two ends of the NTC thermistor 31 respectively. The pins of different temperature detection units 3 can have different lengths. Preferably, the positions of the pins 331 correspond one-to-one with the positions of the first connectors 11 on the PCBA.

[0045] In some embodiments, such as Figure 2 and Figure 5 As shown, the connection structure 33 includes a fisheye pin 332. The control module has an insertion hole 12 corresponding to the fisheye pin 332, and the fisheye pin 332 is connected to the control module 1 through the insertion hole 12. Specifically, the fisheye pin 332 passes through the insertion hole 12, and the distance between the independent PCB board 32 and the PCBA can be adjusted as needed. Preferably, the position of the fisheye pin 332 corresponds one-to-one with the position of the insertion hole 12 on the PCBA.

[0046] In some embodiments, such as Figure 3 , Figure 6 and Figure 8 As shown, the connection structure 33 includes a wire harness 333 and a second connector 334. Multiple wire harnesses of at least one temperature detection unit 3 are connected to the second connector 334. The control module 1 is provided with a third connector 13, and the second connector 334 is connected to the third connector 13. Specifically, the second connector 334 and the third connector 13 have matching pins and sockets, respectively.

[0047] This application utilizes the three structures described above to connect the connecting structure 33 to the corresponding connector structure on the control module 1 during product assembly, thereby enabling signal transmission between the temperature detection unit 3 and the control module 1. The pins, fisheye pins, or wire harnesses of the temperature detection unit can be designed to different lengths to meet the temperature detection requirements of surfaces at different heights.

[0048] Optionally, such as Figure 9 As shown, in some embodiments, the stand-alone PCB board 32 includes:

[0049] The plate body 321 has two connection points for connecting to the connecting structure;

[0050] NTC thermistor mounting island 322, NTC thermistor mounting island 322 has NTC thermistor solder joints, and NTC thermistor mounting island 322 has a cutout 323 around it.

[0051] The connecting part 324 is used to connect the NTC thermistor mounting island 322 and the board body 321.

[0052] This application reduces the heat conduction path and minimizes the impact of PCB materials on the temperature measurement of the NTC thermistor by soldering the NTC thermistor onto the surrounding NTC thermistor mounting island 322, which has perforations. Furthermore, the NTC thermistor mounting island facilitates assembly and positioning during NTC thermistor soldering.

[0053] In some embodiments, the independent PCB board 32 is provided with mounting holes 325 for connecting the independent PCB board 32 to the mounting portion 212. Optionally, the independent PCB board 32 is fixed to the mounting base 21 by screws passing through the mounting holes 325 and the mounting portion 212.
