[0032] In combination with Figures 1 to 2 As shown, according to a specific embodiment of the present application, a vehicle-mounted controller is provided.
[0033] Specifically, the vehicle-mounted controller includes a housing 1 and a heat exchange component 3. The housing 1 at least includes a first chamber 11 and a second chamber 12. The controller body 2 is disposed in the first chamber 11, and the heat exchange component 3 is disposed in the second chamber 12. The heat exchange part of the heat exchange component 3 extends out of the second chamber 12 and extends into the first chamber 11. The heat exchange part is used to control the temperature in the first chamber 11 within a preset temperature range.
[0034] In an embodiment of the present application, the controller body 2 is encapsulated in the second chamber 12 of the housing 1, and the temperature in the second chamber 12 is controlled by the heat exchange component 3. The controller body 2 exchanges heat with the air in the second chamber 12 so that the controller body 2 operates at a preset temperature. For the vehicle-mounted controller in the above solution, the operating temperature of the controller body 2 is indirectly adjusted through the heat exchange component 3, so that the vehicle-mounted controller operates stably, thereby ensuring the reliability and stability of vehicle-mounted wireless communication.
[0035] In an exemplary embodiment of the present application, the heat exchange component 3 includes a semiconductor heat exchange plate 31 and a control circuit. The semiconductor heat exchange plate 31 has a heat exchange part, and the control circuit is electrically connected to the semiconductor heat exchange plate 31. The temperature of the heat exchange part is adjusted by changing the direction of the current in the control circuit.
[0036] Specifically, the semiconductor heat exchange plate 31 includes two metal plates, at least one P-type semiconductor element, and at least one N-type semiconductor element. The two metal plates are arranged oppositely, and the P-type semiconductor element and the N-type semiconductor element are disposed between the two metal plates, and the P-type semiconductor element and the N-type semiconductor element are connected in series. Among them, when there are multiple P-type semiconductor elements, the multiple P-type semiconductor elements are connected in parallel; and when there are multiple N-type semiconductor elements, the multiple N-type semiconductor elements are connected in parallel. The control circuit is connected between the P-type semiconductor element and the N-type semiconductor element. After the control circuit is powered on, one of the metal plates is the cold end and the other metal plate is the hot end. By changing the direction of the current in the control circuit, the cold end and the hot end are switched. Among them, one of the two metal plates extends into the first chamber 11 as the heat exchange part and exchanges heat with the air in the first chamber 11.
[0037] Further, the control circuit includes a first circuit 32, a second circuit 33, and a circuit controller. The first circuit 32 is electrically connected to the semiconductor heat exchange plate 31, and the first circuit 32 is provided with a first switch. The second circuit 33 is electrically connected to the semiconductor heat exchange plate 31, and the second circuit 33 is provided with a second switch. Among them, the direction of the current flow in the second circuit 33 is opposite to the direction of the current flow in the first circuit 32. The circuit controller is respectively signal-connected to the first circuit 32 and the second circuit 33, and the circuit controller is used to control the opening and closing of the first switch and the second switch.
[0038] Specifically, as Figure 2As shown, the first circuit 32 and the second circuit 33 are respectively electrically connected to the semiconductor heat exchange plate 31, and the first circuit 32 and the second circuit 33 are independently arranged. Exemplarily, the first circuit 32 is provided with a first storage battery, the positive electrode of the first storage battery is connected to the P-type semiconductor element, the negative electrode of the first storage battery is connected to the N-type semiconductor element, and the second circuit 33 is provided with a second storage battery, the positive electrode of the second storage battery is connected to the N-type semiconductor element, and the negative electrode of the first storage battery is connected to the P-type semiconductor element. The circuit controller can selectively control one of the first switch and the second switch to close, so as to change the temperature of the heat exchange part of the semiconductor heat exchange plate 31.
[0039] Wherein, variable resistors are connected in series in both the first circuit 32 and the second circuit 33. By adjusting the resistance value, the current in the circuit is adjusted to achieve fine adjustment of the temperature.
[0040] In another exemplary embodiment of the present application, the semiconductor heat exchange plate 31 is connected to the inner wall of the second chamber 12 through a bracket 13. The bracket 13 is provided to facilitate the connection between the semiconductor heat exchange plate 31 and the housing 1.
[0041] In another exemplary embodiment of the present application, the controller body 2 is connected to the heat exchange part of the heat exchange assembly 3.
[0042] Specifically, the controller body 2 is bonded to the heat exchange part through a heat-conducting adhesive. While the controller body 2 exchanges heat with the air in the first chamber 11, the controller body 2 also conducts heat with the heat exchange part to improve the heat exchange efficiency of the controller body 2.
[0043] In another exemplary embodiment of the present application, a partition 14 is provided in the housing 1. The partition 14 divides the inner cavity of the housing 1 into a first chamber 11 and a second chamber 12. A through hole is opened on the partition 14, and the heat exchange part of the heat exchange assembly 3 extends into the first chamber 11 through the through hole.
[0044] Furthermore, a heat-insulating layer is provided on the inner wall of the first chamber 11 of the housing 1.
[0045] Specifically, the heat-insulating layer is a heat-insulating coating applied on the inner wall of the first chamber 11. By providing the heat-insulating layer, the heat conduction between the air inside the housing 1 and the air outside the housing 1 is reduced, so that the first chamber 11 can quickly reach a constant temperature state.
[0046] Furthermore, a heat-insulating layer is provided on the outer wall of the housing 1.
[0047] Specifically, the heat-insulating layer is a heat-insulating coating applied on the outer wall of the housing 1, further reducing the heat conduction between the air inside the housing 1 and the air outside the housing 1, so that the first chamber 11 can quickly reach a constant temperature state.
[0048] In another exemplary embodiment of the present application, the vehicle-mounted controller further includes a limiting and anti-shake filter 4, which is disposed on the outer wall of the housing 1 and is signal-connected to the input end of the controller body 2. Specifically, the limiting and anti-shake filter 4 is signal-connected to the input end of the controller body 2 through a wire 5. The signal received by the controller body 2 is first filtered by the limiting and anti-shake filter 4 to limit the fluctuation and jitter of the signal.
[0049] According to another specific embodiment of the present application, a vehicle is provided, which includes a vehicle-mounted controller, and the vehicle-mounted controller is the vehicle-mounted controller in the above embodiment.
[0050] Specifically, the vehicle-mounted controller includes a housing 1 and a heat exchange component 3. The housing 1 at least includes a first chamber 11 and a second chamber 12. The controller body 2 is disposed in the first chamber 11, and the heat exchange component 3 is disposed in the second chamber 12. The heat exchange part of the heat exchange component 3 extends out of the second chamber 12 and extends into the first chamber 11, and the heat exchange part is used to control the temperature in the first chamber 11 within a preset temperature range. The operating temperature of the controller body 2 is indirectly adjusted through the heat exchange component 3 to enable the vehicle-mounted controller to operate stably, so as to ensure the reliability and stability of vehicle-mounted wireless communication.
