Description

Technical Field

[0001] The utility model relates to the technical field of thermal management, in particular to a heater and a thermal management system with temperature monitoring. Background Art

[0002] Heaters, as heat regulators in automotive thermal management systems, are key temperature control components. Existing heaters require temperature sensors to monitor the temperature of the water path within the system. Specifically, the temperature sensor is placed within the water path, and its pins are connected to the control circuit board via cables.

[0003] However, such an arrangement causes the temperature sensor to be placed outside the control housing (the circuit board is arranged inside the control housing), which affects the data communication between the temperature sensor and the circuit board; and the connection method of the connecting wires is prone to faults such as open circuit and short circuit. Utility Model Content

[0004] The purpose of the present invention includes, for example, providing a heater and thermal management system with temperature monitoring, which can simplify the arrangement of the wire thermostat while ensuring the stable operation of the temperature sensor and also reduce the cost of the temperature sensor.

[0005] The embodiment of the present utility model can be implemented as follows:

[0006] In a first aspect, the present invention provides a heater with temperature monitoring, comprising:

[0007] Water pipe fittings, core assembly, control housing, circuit board and temperature sensor;

[0008] The core assembly has a main pipe along a preset direction; along the preset direction, the main pipe has a first end and a second end opposite to each other; the water pipe is arranged at the first end along the preset direction;

[0009] Along the preset direction, the core assembly is arranged on the outer wall of the control housing;

[0010] The control housing has a through hole extending along the preset direction; the circuit board is arranged in the control housing, the pin end of the temperature sensor is connected to the circuit board, and the sensing end of the temperature sensor passes through the through hole and abuts against the second end of the main line.

[0011] In an optional embodiment, a groove is provided on the outer wall of the control housing, and the through hole is located in the groove;

[0012] The second end has a protrusion; the protrusion is snap-fitted with the groove.

[0013] In an optional embodiment, the through hole is located at the center of the groove.

[0014] In an optional embodiment, the protrusion is in contact with the bottom surface of the groove.

[0015] In an optional embodiment, the core assembly includes a flow channel assembly, multiple heating cores, and a lower end plate; along the preset direction, the lower end plate is arranged at the bottom of the flow channel assembly; the main line extends from the first end to the lower end plate; the protrusion is a raised structure arranged on the bottom of the lower end plate.

[0016] In an optional embodiment, there is a transition section between the protrusion and the plate surface at the bottom of the lower end plate, and a matching surface is provided at the notch of the groove; the transition section and the matching surface can fit each other.

[0017] In an optional embodiment, the transition section and the mating surface are both arc-shaped.

[0018] In an optional embodiment, the plate surface of the lower end plate is in contact with the top surface of the control housing.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0031] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0032] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0033] Please refer to Figure 1 This embodiment provides a heater with temperature monitoring, including a water pipe 100, a core assembly 200, a control housing 300, a circuit board 400 and a temperature sensor 500.

[0034] The core assembly 200 has a main pipe 210 along a preset direction A. Along the preset direction A, the main pipe 210 has a first end 211 and a second end 212 opposite to each other. The water pipe 100 is disposed at the first end 211 along the preset direction A.

[0035] Along the preset direction A, the core assembly 200 is disposed on the outer wall of the control housing 300;

[0036] The control housing 300 has a through hole 310 that passes through along a preset direction A; the circuit board 400 is arranged in the control housing 300, the pin end 510 of the temperature sensor 500 is connected to the circuit board 400, and the sensing end 520 of the temperature sensor 500 passes through the through hole 310 and abuts against the second end 212 of the main line 210.

[0037] One end of the temperature sensor 500 of such a heater with temperature monitoring is directly arranged on the circuit board 400, and the other end passes through the hole in the controller housing to directly contact the core assembly 200 to collect temperature. This simplifies the arrangement of the temperature sensor 500 and is conducive to ensuring the reliability and stability of the temperature collection process. At the same time, the temperature sensor 500 is located at the bottom of the main line 210, which can ensure the accuracy of temperature collection; the sensing end 520 of the temperature sensor 500 passes through the through hole 310 and abuts against the second end 212 of the main line 210, which does not occupy the space of the control housing 300, thereby improving the integration of the heater. Compared with the existing technology that requires a separate connection line to cause problems such as poor reliability of temperature difference collection, the pins of the temperature sensor 500 of this solution are directly connected to the circuit board 400, eliminating the need for the arrangement of the connection line.

[0038] Please continue reading Figure 1 and Figure 2 , for more structural details of the heater with temperature monitoring.

[0039] As can be seen from the figure, in this embodiment of the present invention, the outer wall of the control housing 300 has a groove 332, and the through hole 310 is located within the groove 332. The second end 212 has a protrusion 232, which engages with the groove 332. The interaction between the protrusion 232 and the groove 332 ensures a tight connection between the core assembly 200 and the control housing 300, while also shortening the layout path of the temperature sensor 500.

[0040] In this embodiment of the present invention, the top of the sensing terminal 520 is flush with the top of the through hole 310. This arrangement allows the sensing terminal 520 to maintain stable contact with the main pipe 210 while preventing the sensing terminal 520 from being bumped (the periphery of the through hole 310 provides protection).

[0041] Optionally, in this embodiment, the through hole 310 is located at the center of the groove 332. Optionally, the through hole 310 is a circular through hole 310, and the groove 332 is a cylindrical counterbore, that is, the through hole 310 and the groove 332 are coaxially arranged.

[0042] In this embodiment of the present invention, the protrusion 232 is in contact with the bottom surface of the groove 332. This ensures the stability of the connection between the core assembly 200 and the control housing 300, and also helps to further shorten the arrangement path of the temperature sensor 500.

[0043] Furthermore, in this embodiment of the present invention, the core assembly 200 includes a flow channel assembly 220, a plurality of heating cores 240, and a lower end plate 230. The lower end plate 230 is disposed at the bottom of the flow channel assembly 220 along a predetermined direction A. The main conduit 210 extends from the first end 211 to the lower end plate 230. The protrusion 232 is a raised structure disposed on the bottom of the lower end plate 230. Optionally, the protrusion 232 is a circular boss.

[0044] In this embodiment, the surface of the lower end plate 230 is in contact with the top surface of the control housing 300. This allows the bottom of the core assembly 200 and the control housing 300 to have a larger contact area, thereby ensuring a stable connection between the core assembly 200 and the top surface of the control housing 300.

[0045] As can be seen from the figure, in this embodiment of the present invention, a transition section 231 is provided between the protrusion 232 and the bottom surface of the lower end plate 230. A mating surface 331 is provided at the notch of the groove 332. The transition section 231 and the mating surface 331 can fit together. The provision of the transition section 231 facilitates the assembly of the core assembly 200 and the top of the control housing 300.

[0046] Optionally, the transition section 231 and the mating surface 331 are both arc-shaped.

[0047] In a second aspect, the present invention provides a thermal management system comprising a heater with temperature monitoring according to any one of the aforementioned embodiments. Such a thermal management system has a stable and efficient temperature acquisition function, thereby ensuring the stability of thermal management.

[0048] In summary, the embodiments of the present invention provide a heater and thermal management system with temperature monitoring, which has at least the following advantages:

[0049] A groove 332 is formed by the through hole 310 on the controller housing and the end plate of the core assembly 200. A temperature sensor 500 that can be directly connected to the circuit is provided in the groove 332, which simplifies the arrangement of the wire temperature sensor and also reduces the cost of the temperature sensor 500.

[0050] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
