Description

Technical Field

[0001] This application relates to the technical field of water-cooled plates, and particularly to an external water inlet and outlet water-cooled plate integrated with an NTC. Background Art

[0002] A water-cooled plate is a device for heat dissipation, mainly achieving the effect of heat dissipation and temperature reduction by circulating water or other cooling liquids. The water-cooled plate is mainly applied to battery packs. Due to the high requirement for detecting the temperature of the cooling liquid in the water-cooling system, an NTC is set in the water-cooling system for water temperature detection. The NTC is a thermistor element with a negative temperature characteristic.

[0003] In the related art, a nylon tube is provided on the water-cooled plate, and temperature detection elements such as an NTC thermistor or a thermal resistor are provided on the nylon tube.

[0004] Since the material of the nylon tube is an LDPE layer, the thermal conductivity of the LDPE layer itself is poor, resulting in a certain deviation in the temperature detected by the temperature detection element and affecting the accuracy of the temperature detection data. Utility Model Content

[0005] In order to improve the problem of inaccurate detection by the temperature detection element, this application provides an external water inlet and outlet water-cooled plate integrated with an NTC.

[0006] An external water inlet and outlet water-cooled plate integrated with an NTC provided by this application adopts the following technical solutions:

[0007] An external water inlet and outlet water-cooled plate integrated with an NTC includes a water-cooled plate. A temperature detection module is provided on the water-cooled plate. The temperature detection module includes a metal seat and a temperature detection component. The temperature detection component is disposed on the metal seat, and the metal seat is disposed on the water-cooled plate.

[0008] By adopting the above technical solutions, the temperature of the cooling liquid in the water-cooled plate is detected through the temperature detection module. Since the temperature detection component is disposed on the metal seat and the metal seat conducts the temperature, the thermal conductivity of the metal seat is higher than that of the LDPE layer. Therefore, the temperature detection component can stably detect the temperature of the cooling liquid, reduce the error of the temperature detected by the temperature detection component, and improve the accuracy of the temperature detection data.

[0009] Optionally, the temperature detection component includes a mounting bolt and an NTC thermistor. The mounting bolt is threadedly connected to the metal seat. The NTC thermistor is disposed on the mounting bolt, and the mounting bolt is made of a metal material.

[0010] By adopting the above technical solution, the NTC thermistor is arranged on the mounting bolt, and the mounting bolt is threadedly connected to the metal seat. The mounting bolt is made of metal material, so that the NTC thermistor can detect the temperature of the coolant through the mounting bolt and the metal seat, thus ensuring the accuracy of the temperature detected by the NTC thermistor; Since the sizes of the water-cooled plates are different, the metal seats on different-sized water-cooled plates may also be different. Coupled with the fact that the sizes of the NTC thermistors are the same and it is not easy to adjust according to different metal seats, by threadedly connecting the mounting bolt to the metal seat, the NTC thermistor can adapt to different-sized metal seats, so that the NTC thermistor can be stably installed in different-sized metal seats, increasing the adaptability of the NTC thermistor.

[0011] Optionally, a placement groove is formed on the mounting bolt, the placement groove is for the NTC thermistor to be inserted, a deformable stop strip is arranged on the outer surface of the NTC thermistor, and a limiting groove is formed on the groove wall of the placement groove. When the stop strip is inserted into the limiting groove, the NTC thermistor is fixed in the placement groove.

[0012] By adopting the above technical solution, by inserting the stop strip into the limiting groove, the groove wall of the limiting groove limits the stop strip, so that the NTC thermistor is fixed in the placement groove, and the NTC thermistor can detect the temperature through the heat conduction of the mounting bolt; At the same time, the NTC thermistor is located in the placement groove, reducing the thickness of the mounting bolt, accelerating heat conduction, and reducing heat loss during the heat conduction process, so that the NTC thermistor can stably detect the temperature.

[0013] Optionally, a stop block is arranged on the NTC thermistor, and a stop groove for the stop block to be inserted is formed on the placement groove.

[0014] By adopting the above technical solution, by inserting the stop block into the stop groove, the NTC thermistor is not easy to rotate in the placement groove, so that the NTC thermistor can be more stably electrically connected.

[0015] Optionally, a plurality of limiting grooves are provided, a plurality of stop strips are provided, and each stop strip can be respectively inserted into the corresponding limiting groove.

[0016] By adopting the above technical solution, since both the stop strip and the limiting groove are provided in plurality, and each stop strip can be respectively inserted into the corresponding limiting groove, the fixing degree of the stop strip and the limiting strip is further increased, so that the NTC thermistor can be more stably located in the mounting bolt.

[0017] Optionally, a flat surface is provided on the outer surface of the NTC thermistor.

[0018] By adopting the above technical solution, a flat surface is provided on the outer surface of the NTC thermistor, so that the staff can hold the NTC thermistor, enabling the staff to more easily take out the NTC thermistor from the placement groove.

[0019] Optionally, a fixing groove for inserting the sensing part of the NTC thermistor is provided in the placement groove.

[0020] By adopting the above technical solution, by inserting the sensing part of the NTC thermistor into the fixing groove, the sensing part of the NTC thermistor is made closer to the metal seat, further reducing the distance between the sensing part of the NTC thermistor and the metal seat, so that the NTC thermistor can detect the temperature more accurately.

[0021] Optionally, the bottom wall of the placement groove has an inclined surface, and the distance between the inclined surface and the axis of the NTC thermistor gradually decreases along the direction from the placement groove to the fixing groove.

[0022] By adopting the above technical solution, since the distance between the inclined surface and the axis of the NTC thermistor gradually decreases along the direction from the placement groove to the fixing groove, the sensing part of the NTC thermistor can slide into the fixing groove along the inclined surface, facilitating the insertion of the sensing part of the NTC thermistor into the fixing groove.

[0023] Optionally, there is a flow channel between the water cooling plates. The flow channel has a water inlet, a water outlet and a circulation pipeline. The water inlet is used for the coolant to flow into the circulation pipeline, the water outlet is used for the coolant to flow out of the circulation pipeline, and the metal seat is arranged on the water cooling plate corresponding to the water outlet.

[0024] By adopting the above technical solution, by arranging the metal seat corresponding to the water outlet, the heat conducted by the metal seat is the heat at the water outlet, enabling the NTC thermistor to more accurately detect the temperature of the coolant at the water outlet, so as to obtain an accurate heat transfer coefficient.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The temperature of the coolant in the water cooling plate is detected by the temperature detection module. Since the temperature detection component is arranged on the metal seat and the metal seat conducts the temperature, and the thermal conductivity of the metal seat is higher than that of the LDPE layer, the temperature detection component can stably detect the temperature of the coolant, reducing the error of the temperature detected by the temperature detection component and improving the accuracy of the temperature detection data.

[0027] 2. Insert the stop bar into the limit groove, and let the groove wall of the limit groove limit the stop bar, so that the NTC thermistor is fixed in the placement groove. The NTC thermistor can detect the temperature through the heat conduction of the mounting bolt. At the same time, the NTC thermistor is located in the placement groove, reducing the thickness of the mounting bolt, accelerating heat conduction, and reducing heat loss during the heat conduction process, enabling the NTC thermistor to stably detect the temperature.
