[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0036] See Figure 1 The thermal management system 100 of this disclosure embodiment will be described as shown.

[0037] The thermal management system 100 of this embodiment includes a return air duct 10, an exhaust air duct 20, a fresh air duct 30, and a supply air duct 40. Taking a vehicle as an example, the supply air duct is connected to the vehicle cabin to deliver air processed by the thermal management system 100 into the vehicle cabin for cooling or heating. The return air duct 10 is also connected to the vehicle cabin to introduce air from the vehicle cabin into the return air duct 10 for further processing and utilization. The exhaust air duct 20 leads to the outside of the vehicle to exhaust air from the vehicle cabin into the external space. The fresh air duct 30 also leads to the outside of the vehicle to introduce air from the external space into the thermal management system 100.

[0038] In some embodiments, such as Figure 1 As shown, the thermal management system 100 also includes a first dehumidification device 5, the dehumidification section 51 of which can be selectively disposed on the return air duct 10 or the supply air duct 40. That is, the dehumidification section 51 of the first dehumidification device 5 can be selectively disposed on the return air duct 10 to absorb moisture from the return air in the return air duct 10, or it can be selectively disposed on the supply air duct 40 to absorb moisture from the air about to be delivered through the supply air duct 40, thereby achieving moisture absorption under different operating conditions.

[0039] The first dehumidifier 5 can absorb moisture when the target object is in either cooling or heating dehumidification mode.

[0040] In this embodiment, during heat recovery in heating mode, the dehumidification section 51 of the first dehumidification device 5 can be installed on the return air duct 10 to absorb moisture from the return air in the return air duct 10, preventing the moisture in the return air from being released back into the supply air. During heat recovery in cooling mode, the dehumidification section 51 of the first dehumidification device 5 can be installed on the supply air duct 40 to absorb moisture from the air about to be supplied through the supply air duct 40, thereby achieving moisture absorption in cooling mode.

[0041] In some embodiments, Figure 1 The return air duct 10 is provided with a first air outlet and a second air outlet. The first air outlet of the return air duct 10 is an air outlet that communicates with the supply air duct, and the second air outlet of the return air duct 10 is used to supply air into the object and is connected to the space of the object.

[0042] The target of the action is, for example, a vehicle cabin, an aircraft cabin, or a relatively enclosed space, etc., without limitation.

[0043] by Figure 1 For example, return air is the air supplied to the object of action. Taking a vehicle as an example, the air in the object of action is the air in the vehicle's cabin. The air in the object of action can be supplied to the return air duct 10 through the second air inlet of the return air duct 10.

[0044] In this embodiment, Figure 1 The air supply duct 40 is also provided with a first air outlet and a second air outlet. The first air outlet of the air supply duct is an air outlet that communicates with the return air duct 10. The second air outlet of the air supply duct 40 is used to deliver air to the target, such as delivering air processed by the thermal management system 100 to the vehicle cabin.

[0045] In this embodiment, the first air outlet of the supply air duct 40 is connected to the first air outlet of the return air duct 10. Here, the first air outlet of the supply air duct 40 and the first air outlet of the return air duct 10 can be the same air outlet or they can be different air outlets that are connected. No limitation is made here.

[0046] In this embodiment, the dehumidification section 51 of the first dehumidification device 5 can be selectively located at the second air outlet of the return air duct 10 or the second air outlet of the supply air duct. In this way, the dehumidification section 51 of the first dehumidification device 5 can absorb moisture from the supplied air at the second air outlet of the supply air duct 40 leading to the target, and absorb moisture from the return air at the second air outlet of the target leading to the return air duct 10, thereby enhancing the dehumidification effect.

[0047] In some embodiments, such as Figure 1 and Figure 3As shown, the first dehumidification device 5 may further include a first limiting part 52 and a second limiting part 53. The first limiting part 52 is disposed on the return air duct 10, and the second limiting part 53 is disposed on the supply air duct 40. The dehumidification part 51 may be selectively disposed on either the first limiting part or the second limiting part. By providing limiting parts, the reliability of switching the position of the dehumidification part 51 is improved. In this embodiment, the first limiting part 51 may be disposed at the second air outlet of the return air duct 10, and the second limiting part 52 may be disposed at the second air outlet of the supply air duct 40. Thus, when the dehumidification part 51 is disposed on the first limiting part 51, the purpose of disposing of the dehumidification part 51 at the second air outlet of the return air duct 10 is achieved; and when the dehumidification part 51 is disposed on the second limiting part 52, the purpose of disposing of the dehumidification part 51 at the second air outlet of the supply air duct 40 is achieved.

[0048] For example, the dehumidifier 41 can be configured to be fixed to the first limiting part 52 when the target object is in dehumidification mode or heating dehumidification mode. Alternatively, the dehumidifier 51 can be configured to be fixed to the second limiting part 53 when the target object is in cooling dehumidification mode.

[0049] In some embodiments, such as Figure 4 As shown, the dehumidifier 51 has a semi-circular cross-section. The first limiting part 52 and the second limiting part 53 can be fixedly connected to the corresponding channels, and the dehumidifier 51 can slide on the first limiting part 52 and the second limiting part 53 respectively. When the target is in different modes, the diameter of the dehumidifier 51 is in contact with the dividing wall 401 of the supply air duct 40 and the return air duct 10. That is, when the target is in dehumidification mode or heating dehumidification mode, the dehumidifier 51 moves to the first limiting part 52 and is fixed thereon. When the target is in cooling dehumidification mode, the dehumidifier 51 moves to the second limiting part 53 and is fixed thereon.

[0050] In some examples, the first dehumidification device 5 may also include a drive motor, which can drive the dehumidification part 51 to slide on the first limiting part 52 and the second limiting part 53 by means of gear transmission or belt pulley transmission. The specific driving method is prior art and is not limited here.

[0051] In some examples, the first dehumidification device 5 is, for example, a moisture-absorbing metal-organic frame dehumidification rotor (MOF dehumidification rotor).

[0052] In some examples, when the target object is in dehumidification mode, the heat recovery system 100 can also remove residual moisture on the first dehumidifier 5 to extend the service life of the first dehumidifier 5.

[0053] In some embodiments, Figure 1The thermal management system 100 may further include a first heat exchanger 41 and a first damper 2. The return air duct 10 is provided with the aforementioned second air outlet, and the exhaust air duct 20 is provided with a first air outlet communicating with the internal space of the object being processed, and a second air outlet communicating with the external space.

[0054] The second air outlet of the exhaust duct 20 is used to send air to the external space of the object, and the first air outlet of the exhaust duct 20 is connected to the second air outlet of the return air duct 10.

[0055] by Figure 1 For example, exhaust ventilation is the air sent to the external space of the object being treated. Taking the vehicle cabin as an example, it is the air discharged to the external environment. The thermal management system 100 can discharge the air in the vehicle cabin to the external environment through the second air outlet of the exhaust duct 20.

[0056] The fresh air duct 30 is equipped with a first air inlet, which is used to supply air from the outside space into the thermal management system 100.

[0057] by Figure 1 For example, fresh air refers to the air outside the target. Taking the vehicle cabin as the target, the air outside the target is the air of the external environment. The air of the external environment can be sent into the fresh air duct 30 through the first air inlet of the fresh air duct 30.

[0058] In this embodiment, the first heat exchanger 41 is disposed on the air supply duct 40, and the first damper 2 is disposed on the fresh air duct 30.

[0059] by Figure 1 For example, air supply refers to the air delivered to the target object. Taking the vehicle cabin as an example, the air delivered to the target object is the air delivered to the vehicle cabin. The air delivered to the target object can be output to the vehicle cabin through the first air outlet of the air supply duct 40.

[0060] In some examples, such as Figure 1 As shown, taking a vehicle as an example, the first heat exchanger 41 is, for example, an in-vehicle heat exchanger. The first heat exchanger 41 can exchange heat with the air in the air supply duct 40 through the refrigerant pipeline.

[0061] In this embodiment, when the first damper 2 is open, the fresh air entering the fresh air duct 30 and the return air entering the return air duct 10 merge and enter the supply air duct 20. After passing through the first heat exchanger 41 for heat exchange treatment, the air is then output to the target object so as to achieve temperature regulation of the target object through the first heat exchanger 41.

[0062] In some embodiments, such as Figure 1As shown, the first air outlet of the fresh air duct 30 is connected to the first air outlet of the return air duct 10 and the first air outlet of the supply air duct 20 respectively. The first air damper 2 can be set on the first air outlet of the fresh air duct so as to control the connection path between the fresh air duct 30 and the supply air duct 20.

[0063] In this embodiment, the fresh air duct 30 is also provided with a second air outlet, which is connected to the third air outlet of the supply air duct 20. Here, the second air outlet of the fresh air duct 30 and the third air outlet of the fresh air duct 20 can be the same air outlet or they can be different air outlets that are connected.

[0064] In this embodiment, the thermal management system 10 further includes a second damper 4, which is disposed between the second air outlet of the fresh air duct 30 and the third air outlet of the supply air duct 20, so as to control the connection path between the fresh air duct 30 and the supply air duct 20.

[0065] In this embodiment, when the second air damper 4 is in the open state, the fresh air in the fresh air duct 30 can enter the supply air duct through the third air inlet of the supply air duct 20.

[0066] In some embodiments, such as Figure 1 As shown, the thermal management system 100 may also include a second heat exchanger 31 and a third damper 3.

[0067] In this embodiment, the second heat exchanger 31 can be a heat recovery device, which can recover energy within the target object or other types of energy, and convert the recovered energy into usable heat. For example... Figure 1 As shown, taking the vehicle cabin as an example, the heat exchanger 31 can obtain the energy recovered from the vehicle motor's kinetic energy through the waste water circuit, and can also obtain the heat generated inside the cabin.

[0068] In this embodiment, the fresh air duct 30 is further provided with a third air outlet, which is connected to the first air outlet of the fresh air duct 30. A second heat exchanger 31 is disposed on the fresh air duct 30 and located between the second and third air outlets of the fresh air duct 30. When the thermal management system is in heating and dehumidification mode, the first heat exchanger 41 can heat the air input through the second air outlet of the return air duct 10, and the second heat exchanger 31 can heat the air input through the first air outlet of the fresh air duct 30, causing the heated air to accumulate within the supply air duct 40 and be discharged from the second air outlet of the supply air duct 40.

[0069] In some examples, taking a vehicle as the target, the heating and dehumidifying mode involves dehumidifying and heating the air inside the vehicle's cabin. For example... Figure 1As shown, when the thermal management system is in heating and dehumidification mode, part of the return air is input into the return air duct 10 and the other part is input into the exhaust air duct 20. At the same time, fresh air is input into the fresh air duct 30. The fresh air can be heated by the second heat exchanger 31. The heated fresh air and part of the return air are gathered in the supply air duct 40. The first heat exchanger 41 heats the heated fresh air and part of the return air again and sends the heated air out from the second air outlet of the supply air duct 40.

[0070] In other words, when the thermal management system is in heating and dehumidification mode, the thermal management system 100 can use the first heat exchanger 41 and the second heat exchanger 31 to heat the air together, so that the air can be heated up quickly, thereby reducing the energy consumption generated by the first heat exchanger 41 and improving the energy utilization efficiency of the thermal management system 100.

[0071] In some embodiments, in order to control the ratio of return air to exhaust air, a fourth damper 1 is provided between the return air duct 10 and the supply air duct 40. The fourth damper 1 is configured to adjust the ratio of air supplied from the second air inlet of the return air duct 10 to the return air duct 10 and the supply air duct 40.

[0072] In some examples, such as Figure 1 As shown, by controlling the tilt angle of the fourth damper 1, the ratio of return air to exhaust air can be changed to achieve air supply with different wind speeds.

[0073] In some embodiments, such as Figure 1 As shown, the return air duct 10 is located between the exhaust air duct 20 and the supply air duct 40. The return air duct 10, exhaust air duct 20, and supply air duct 40 are all located on the same side of the fresh air duct 30. This results in shorter lengths for the return air duct 10 and the supply air duct 40, effectively reducing heat loss caused by excessively long ducts. Furthermore, this structural arrangement allows for a closer relative distance between the first heat exchanger 41 and the second heat exchanger 42, further reducing heat loss caused by excessively long ducts.

[0074] In some embodiments, such as Figure 2 As shown, when the thermal management system is in dehumidification mode, the second air inlet of the return air duct 10 and the second air inlet of the supply air duct 40 are closed. The second heat exchanger 31 heats the air supplied through the first air inlet of the fresh air duct 30, so that the heated air passes through the supply air duct 40, the return air duct 10 and the exhaust air duct 20 in sequence, and is sent out from the second air inlet of the exhaust air duct 20.

[0075] In some examples, taking a vehicle as the target, the dehumidification mode involves dehumidifying and heating the air within the duct. For example... Figure 1As shown, when the thermal management system is in dehumidification mode, fresh air is introduced into the fresh air duct 30, the second heat exchanger 31 and the first heat exchanger 41 heat the fresh air, and then send it out from the exhaust duct 20. In this way, the second heat exchanger 31 and the first heat exchanger 41 can be used to dehumidify each duct and the devices in the duct, so as to reduce the humidity inside the duct and improve the service life of the thermal management system 100.

[0076] In some embodiments, such as Figure 1 As shown, the fresh air duct 30 may include a guide duct 301 and a heat exchange duct 302. The first damper 2 may be set between the guide duct 301 and the return air duct 10. The third damper 3 may be set between the guide duct 301 and the heat exchange duct 302. The second damper 4 may be set between the supply air duct 40 and the heat exchange duct 302.

[0077] like Figure 1 As shown, when the thermal management system is in heating and dehumidification mode, the first damper 2 is closed, the third damper 3 and the second damper 4 are open, the first heat exchanger 41 heats the air supplied through the second air outlet of the return air duct 10, and the second heat exchanger 31 heats the air supplied through the first air outlet of the fresh air duct 30, so that the heated air gathers in the supply air duct 40 and is sent out from the second air outlet of the supply air duct 40.

[0078] In some examples, taking a vehicle as the target, the first air door 2 is closed, the third air door 3 and the second air door 4 are open, and the fresh air can be heated by the second heat exchanger 31. A portion of the return air can be gathered with the heated fresh air in the air supply duct 40 and heated by the first heat exchanger 41, so that the heated air can be sent out through the second air outlet of the air supply duct 40.

[0079] like Figure 3 As shown, when the thermal management system is in the cooling and dehumidification mode, the first damper 2 is open, the third damper 3 and the second damper 4 are closed, and the first heat exchanger 41 cools the air supplied through the first air outlet of the return air duct 10, so that the cooled air is sent out from the second air outlet of the supply air duct 40.

[0080] In some examples, taking a vehicle as the target, the first air door 2 is opened, the third air door 3 and the second air door 2 are closed, and a portion of the fresh air and return air are gathered in the air supply duct 40 and cooled by the first heat exchanger 41, so that the cooled air can be sent out of the second air outlet of the air supply duct 40.

[0081] In other words, by setting the first damper 2, the third damper 3, and the second damper 4, the cooling and heating functions of the thermal management system are realized.

[0082] In some embodiments, in order to further improve the heat exchange efficiency of the second heat exchanger 31, such as Figure 1As shown, the heat exchange duct 302 includes a first channel located on one side of the third damper 3 and a second channel located on one side of the second damper 4, with the first and second channels arranged perpendicularly. In other words, the channel between the second heat exchanger 31 and the heat exchange duct 302 forms a "U" shape, allowing the fresh air supplied to the heat exchange duct 302 to exchange heat more fully with the second heat exchanger 31, thereby improving the heat exchange efficiency of the second heat exchanger 31.

[0083] In some embodiments, to achieve dehumidification of both fresh air and exhaust air, the thermal management system 100 may further include a second dehumidification device 6, which is disposed on the second air outlet of the exhaust duct 20 and the fourth air outlet of the fresh air duct 30. In this embodiment, the second dehumidification device 6 is, for example, a moisture-absorbing metal-organic frame dehumidification rotor (MOF dehumidification rotor), which can dehumidify both fresh air and exhaust air separately to improve the utilization efficiency of the second dehumidification device 6.

[0084] In some embodiments, a heat recovery rotor may be provided at the second air outlet of the exhaust duct 20 and the first air outlet of the fresh air duct 30, with the heat recovery rotor located outside the second dehumidification device 6.

[0085] In the heating heat recovery and dehumidification mode, fresh air enters through the first vent of the fresh air duct 30 and exchanges heat with the exhaust air reaching the second vent of the exhaust duct 20 via a heat recovery rotor. The fresh air temperature rises, while the exhaust air temperature decreases. The second dehumidifier 6, through continuous rotation, carries the water vapor absorbed by the fresh air duct 30 to the exhaust duct 20, where it is then carried away by the exhaust air. In the cooling heat recovery and dehumidification mode, fresh air enters through the fresh air duct 30 and exchanges heat with the exhaust air reaching the second vent of the exhaust duct 20 via a heat recovery rotor. The fresh air temperature decreases, while the exhaust air temperature increases.

[0086] In dehumidification mode, fresh air enters the heat exchange duct through the third air damper 3, and after heat exchange and heating, it enters the return air and exhaust air duct through the first air damper 2 to heat the first dehumidification device 5 and the second dehumidification device 6, so as to realize the condensation and dehumidification of water vapor adsorbed on the dehumidification device, and make the dehumidification device be used repeatedly.

[0087] In some embodiments, the thermal management system 100 may further include a controller, such as a control chip, which can control the opening or closing of the fourth damper 1, the first damper 2, the third damper 3, the second damper 4, and the air vents of each air duct. The specific control method is existing technology and will not be described in detail here.

[0088] An electrical energy device according to an embodiment of this disclosure includes a thermal management system 100, which is the thermal management system 100 of any of the above embodiments. The electrical energy device may be, for example, a vehicle, aircraft, ship, or central air conditioning, etc., and is not limited thereto. In other words, when the above-mentioned electrical energy device is equipped with the heat recovery system 100, it can effectively reduce energy consumption.
