Abstract
Description
Technical Field
[0001] This utility model relates to a hybrid drive mode independent water circuit semiconductor chip heating system. Background Technology
[0002] Traditional heating systems primarily use electric heating technology, utilizing the Ohmic effect of resistance to generate heat. This method is not only energy-intensive but also slow in heating speed. Modern semiconductor chips, however, offer advantages such as high-precision temperature control and rapid response, resulting in higher heating efficiency and excellent performance in heating systems.
[0003] However, existing semiconductor chip-based heating systems use an uncontrollable mixed water circuit, which cannot be adjusted according to the characteristics of different driving modes. This increases thermal resistance and causes reverse heat transfer, thereby weakening the heating effect and increasing energy consumption. Utility Model Content
[0004] The technical problem to be solved by this utility model is: how to solve the problems of poor heating effect and high energy consumption, and to provide a hybrid drive mode independent water circuit semiconductor chip heating system.
[0005] To solve the above problems, this utility model is achieved through the following technical solution:
[0006] A hybrid drive mode independent water circuit semiconductor chip heating system includes an inlet tank, a main tank and an auxiliary tank. The inlet tank is connected to an inlet, the main tank is provided with a main outlet, and the auxiliary tank is provided with an auxiliary outlet. The main outlet and the auxiliary outlet are connected to a regulating valve, and the outlet side of the regulating valve is connected to the main outlet.
[0007] The water inlet tank is connected to at least one wide water channel and at least one narrow water channel. The wide water channel is connected to the main water tank, and the narrow water channel is connected to the auxiliary water tank.
[0008] Furthermore, the outer wall of the wide water channel is in close contact with the heat dissipation metal plate; the narrow water channel connects to the cold end of the semiconductor chip, and the hot end of the semiconductor chip connects to the heat dissipation metal plate.
[0009] Both wide and narrow waterways are formed by two waterway walls, with the inner diameter of the wide waterway wall being larger than that of the narrow waterway wall.
[0010] The volume of the main water tank is the sum of the volumes of each wide waterway.
[0011] The main water tank and the inlet water tank are arranged symmetrically.
[0012] Each narrow waterway is connected to the auxiliary water tank via a branch pipe.
[0013] The branch pipe is circular, and its volume is the same as that of the connected narrow waterway.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] like Figure 1 , Figure 2 , Figure 3As shown, a hybrid drive mode independent water circuit semiconductor chip heating system includes an inlet tank 2, a main water tank 7, and a secondary water tank 12. The inlet tank 2 is connected to an inlet 1, the main water tank 7 is provided with a main outlet 10, and the secondary water tank 12 is provided with a secondary outlet 11. The main outlet 10 and the secondary outlet 11 are connected to a regulating valve 8, and the outlet side of the regulating valve 8 is connected to a main outlet 9.
[0023] The water inlet tank 2 is connected to at least one wide water channel 6 and at least one narrow water channel 3. The wide water channel 6 is connected to the main water tank 7, and the narrow water channel 3 is connected to the auxiliary water tank 12.
[0024] Furthermore, the outer wall of the wide water channel 6 is in close contact with the heat dissipation metal plate 5; the narrow water channel 3 is connected to the cold end of the semiconductor chip 4, and the hot end of the semiconductor chip 4 is connected to the heat dissipation metal plate 5.
[0025] It should be noted that all of the above structures are encapsulated inside the heater housing.
[0026] Furthermore, both the wide channel 6 and the narrow channel 3 are formed by two channel walls, but the inner diameter of the wide channel 6 is larger than that of the narrow channel 3.
[0027] Furthermore, the volume of the main water tank 7 is the sum of the volumes of each wide water channel 6, so as to ensure that the flow velocity is basically the same everywhere during the liquid circulation process. The main water tank 7 has a large volume, so the main water tank 7 and the inlet water tank 2 are arranged symmetrically.
[0028] Furthermore, and even better, each narrow water channel 3 is connected to the auxiliary water tank 12 via a branch pipe 13. The branch pipe 13 connected to the bottom opening of the narrow water channel 3 is a circular pipe, and its volume is the same as that of the connected narrow water channel 3. This ensures that there is no extra resistance during liquid circulation while minimizing the overall height dimension and not affecting the air intake. The volume of the auxiliary water tank 12 is the sum of the volumes of each narrow water channel 3. Its volume is relatively small, so the auxiliary water tank 12 is arranged below the main water tank 7, which increases its volume while ensuring practicality.
[0029] Thus, this utility model forms a main return water channel and a secondary return water channel, and the main return water channel and the secondary return water channel are switched by the regulating valve 8.
[0030] The main return water channel is as follows: inlet 1—inlet tank 2—wide water channel 6—main water tank 7—main outlet 10.
[0031] The secondary return water channel is as follows: inlet 1—inlet tank 2—narrow waterway 3—secondary water tank 12—secondary outlet 11.
[0032] The working principle of this utility model is as follows:
[0033] exist Figure 2The diagram illustrates the specific structure of the main return water channel. The main return water channel is laid out as follows: inlet 1 is connected to inlet tank 2; inlet tank 2 is connected to several wide water channels 6, which are interconnected; the other end of each wide water channel 6 is connected to and interconnected with the main water tank 7; the main outlet 10 of the main water tank 7 is connected to regulating valve 8, thus communicating with the main outlet 9. The main return water channel operates in fuel mode. When the vehicle enters fuel mode, operating regulating valve 8 opens the main return water channel (inlet 1—inlet tank 2—wide water channels 6—main water tank 7—main outlet 10) and closes the secondary return water channel (inlet 1—inlet tank 2—narrow water channel 3—secondary water tank 12—secondary outlet 11). In fuel mode, the liquid temperature at the inlet 1 is as high as 90°C. Therefore, a wide water channel 6 is used and is closely attached to the heat dissipation plate 5 to quickly and efficiently transfer heat to the vehicle. The volume of the main water tank 7 is the sum of the volumes of each wide water channel 6 to ensure that the flow rate is basically the same at all points during the liquid circulation process. The main water tank 7 has a large volume, so the main water tank 7 and the inlet water tank 2 are arranged symmetrically.
[0034] exist Figure 3 The diagram illustrates the specific structure of the secondary return water channel. The secondary return water channel is laid out as follows: inlet 1 is connected to inlet tank 2, inlet tank 2 is connected to several narrow water channels 3 and runs through them, the other end of each narrow water channel 3 is open at the bottom and connected to branch pipe 13, the other end of branch pipe 13 is connected to secondary water tank 12, and the secondary outlet 11 of secondary water tank 12 is connected to regulating valve 8, thus connecting to the main outlet 9. The secondary return water channel operates in electric mode. When the vehicle enters electric mode, operating regulating valve 8 opens the secondary return water channel and closes the main return water channel. In electric mode, the liquid temperature at inlet 1 is room temperature, heated by semiconductor chip 4. The liquid in the narrow water channels 3 carries away the cold energy from the cold end of the semiconductor chip, and the heat dissipation metal plate 5 transfers the heat from the hot end of the semiconductor chip.
[0035] The width and length of the opening at the bottom of the narrow channel 3 are the same as the width and length of the inlet of the narrow channel 3, so as to ensure that the inlet and outlet flow rates are the same during liquid circulation and to ensure that the cold end temperature of the semiconductor chip 4 is uniform.
[0036] The channel 13 connected to the bottom opening of the narrow water channel 3 is a circular tube, and its volume is the same as that of the connected narrow water channel 3. This ensures that there is no extra resistance during liquid circulation while minimizing the overall height dimension and not affecting the air intake. The volume of the auxiliary water tank 12 is the sum of the volumes of each narrow water channel 3. Its volume is relatively small, so it is arranged below the main water tank 7 to increase its volume while ensuring practicality.
[0037] Both modes share the same inlet tank 2. The main outlet 10 and the auxiliary outlet 11 are both connected to the regulating valve 8, which allows for easy adjustment. Regardless of the mode, there is liquid in both the wide water channel 6 and the narrow water channel 3, ensuring continuous and uniform heat transfer.
[0038] The beneficial effects of this utility model are as follows: 1. The independent design of the main return water channel and the auxiliary return water channel greatly improves the heat exchange efficiency between the liquid and the semiconductor chip and the heat transfer capacity of the warm air. On the one hand, the main return water channel ensures that the liquid circulates at a large flow rate, which can promptly carry away heat and transfer it to the space that needs heating; on the other hand, the auxiliary return water channel carries the lower-temperature liquid out at a small flow rate and high velocity, effectively improving the overall heating efficiency of the warm air system; at the same time, the independent water channels avoid the obstruction of heat by the narrow channel in the fuel mode and the reduction of the main circuit's heat by the cold air return of the auxiliary water channel in the electric vehicle mode. 2. Each water channel is designed according to the characteristics of different driving modes, improving heat transfer capacity, reducing energy consumption, and ensuring reasonable overall size, thereby further improving energy utilization and the service life of the semiconductor chip.
[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
