Description

Technical Field

[0001] The utility model relates to the technical field of thermal management, in particular to a thermal management integrated device. Background Art

[0002] In the vehicle temperature control system, the cooling system and the heating system both play a very important role. At present, the vehicle thermal management system includes components such as compressors, heaters, and controllers. The controller is used to control the cooling of the compressor and the heating of the heater, thereby realizing thermal management control of the vehicle as needed.

[0003] In the prior art, in order to achieve structural integration, some thermal management devices integrate the heat dissipation of the compressor, heater, and controller together. Specifically, a number of IGBTs are generally provided in the controller. IGBT stands for Insulate-Gate Bipolar Transistor, which means insulated gate bipolar transistor in Chinese. It is a composite fully controlled voltage-driven power semiconductor device composed of a bipolar transistor and an insulated gate field effect transistor. IGBT is the core device for energy conversion and transmission, also known as the "CPU" of power electronic devices, and is used in converter systems with a DC voltage of 600V and above, such as rail transportation, smart grids, aerospace, electric vehicles, and new energy equipment. The function of IGBT is to convert AC and DC, and IGBT also undertakes the function of high and low voltage conversion. Generally speaking, the number of IGBTs is determined according to the required power. IGBT has a large working power consumption and a high heat generation, and its heat dissipation problem needs to be considered during design.

[0004] Some thermal management integrated devices in the prior art refer to Figure 1As shown, the compressor 1' and the heating component 2' are respectively fixed on the opposite sides of the controller 3', and the IGBT 31' is attached to the inner wall of the mounting cavity 301' of the controller 3' close to the side of the compressor 1', and the heat is dissipated by the low-temperature refrigerant sucked in by the compressor 1'. However, such an arrangement also has certain defects. First, affected by factors such as the internal structure of the compressor 1', the refrigerant gas flow field will be uneven, and the cooling effect of the IGBT 31' will be greatly affected by the working conditions. When the compressor 1' inhales a high flow rate of low-temperature refrigerant, the refrigerant flow rate is large, and the heat exchange between the IGBT 31' and the low-temperature refrigerant is more sufficient; but when the inhaled refrigerant flow rate is low, the disadvantage of the uneven refrigerant gas flow field will be magnified, which may cause some IGBT 31' to be insufficiently in contact with the low-temperature refrigerant and cannot be fully cooled. The heat exchange effects of each IGBT31' are different, resulting in temperature differences, uneven temperatures and heat exchange efficiencies, and some IGBT31's with low heat exchange efficiency are at risk of overheating. In addition, the reliability of IGBT31's heat dissipation by inhaling low-temperature refrigerant through compressor 1' is low. The pump body inside compressor 1' is a wearable part, and there is a certain possibility of failure after long-term operation. Once compressor 1' fails or stops, it cannot inhale low-temperature refrigerant, and IGBT31' cannot effectively dissipate heat, and there is an immediate risk of high-temperature overheating and damage.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] This embodiment provides a thermal management integrated device. Figures 2 to 4 As shown, the thermal management integrated device includes a compressor 1, a heating component 2 and a controller 3. The heating component 2 includes a shell 21 and a heating element 22 disposed in the shell 21. The shell 21 has a heat exchange cavity. The shell 21 is provided with a circulation inlet 2101 and a circulation outlet 2102 connected to the heat exchange cavity. The heating element 22 is used to heat the heat exchange medium in the heat exchange cavity.

[0045] The controller 3 includes a housing 31 and a control body. The housing 31 has an installation cavity 301. The control body is arranged in the installation cavity 301. The compressor 1 and the housing 21 are respectively fixed on opposite sides of the housing 31. The compressor 1 and the heating element 22 are respectively connected to the control body for communication. The control body includes a plurality of IGBTs 32, which are attached to the cavity wall of the installation cavity 301 close to the housing 21.

[0046] In this embodiment, IGBT32 is attached to the cavity wall of the installation cavity 301 of the controller 3 near the housing 21. When the liquid heat exchange medium is circulated in the heat exchange cavity, the cooling medium in the heat exchange cavity cools the IGBT32 through the housing 21 and the cavity wall of the installation cavity 301 of the controller 3. The heat dissipation and cooling of the IGBT32 by the circulating heat exchange medium can make the temperature of each IGBT32 uniform, and the liquid heat exchange medium does not have an uneven flow field, so that each IGBT32 can achieve uniform and stable heat dissipation. Compared with the compressor 1, the circulation pump used to drive the circulation of the heat exchange medium has a lower probability of failure and is not easy to be damaged, and can also ensure the reliability of cooling the IGBT32.

[0047] In this embodiment, the IGBT 32 is communicatively connected with the compressor 1 and the heating component 2 .

[0048] In this embodiment, the heat exchange medium is set as a fluid medium. Preferably, the heat exchange medium is set as water.

[0049] Specifically, when the heating element 22 needs to be heated, the vehicle control unit transmits a signal to the controller 3, and the controller 3 controls the heating element 22 to heat. The low-temperature heat exchange medium flows into the heat exchange flow channel from the circulation inlet 2101, and the heating element 22 generates heat to heat the heat exchange medium in the heat exchange flow channel. After absorbing the heat, the heat exchange medium flows through the heat exchange flow channel and flows out through the circulation outlet 2102 and is introduced into the vehicle's heating system. After heat exchange in the heating system, it returns to the circulation inlet 2101, forming a complete cycle to achieve the heating function.

[0050] In this embodiment, the controller 3 can control the operation of the compressor 1 alone to realize the refrigeration cycle; can control the operation of the heating element 22 alone to realize the heating function; or can control the operation of the compressor 1 and the heating element 22 at the same time to perform heating and refrigeration cycles at the same time.

[0051] Optionally, the compressor 1 includes an air intake hole 11 and an air discharge hole 12 arranged at intervals along the same side of the compressor 1, and the air discharge hole 12 is arranged on a side away from the controller 3 compared to the air intake hole 11. Optionally, the compressor 1 can be a rotor compressor 1, a swash plate compressor 1, a scroll compressor 1 or a piston compressor 1, etc.

[0052] In this embodiment, a heat conducting layer is sandwiched between the cavity wall of the mounting cavity 301 and the housing 21. Specifically, the heat conducting layer can be configured as thermal conductive silicone grease, which can enhance the heat exchange efficiency, ensure heat transfer between the mounting cavity 301 and the heat exchange cavity, and further achieve reliable cooling of the IGBT 32.

[0053] Furthermore, the thermal management integrated device also includes a monitoring component (not shown), which is used to detect the operation of the circulation pump. When the circulation pump is working normally, the circulation pump circulates the heat exchange medium into the heat exchange chamber; the control body is suitable for cutting off the power when the monitoring component detects that the circulation pump is working abnormally, so that IGBT32 stops working. Specifically, when the circulation pump is working abnormally, the circulation flow of the heat exchange medium is also affected accordingly, so that reliable cooling cannot be provided for IGBT32. By setting up a monitoring component, when the detection component detects that the circulation pump is working abnormally, it communicates with the control body in real time, so that the control body is powered off in time, that is, IGBT32 is powered off. Thereby avoiding the situation where IGBT32 continues to work and burns out when it cannot be effectively cooled.

[0054] Optionally, the monitoring component may be a current sensor for monitoring the current of the normal operation of the circulation pump, or a voltage sensor for monitoring the current of the normal operation of the circulation pump, or other inductive monitoring elements, which are not limited in detail herein.

[0055] Furthermore, the thermal management integrated device also includes an alarm module that is communicatively connected to the control body. The control body is adapted to control the alarm module to sound an alarm when the monitoring component detects that the circulation pump is working abnormally. Specifically, by setting the alarm module, the control body promptly controls the alarm module to sound an alarm when receiving abnormal working of the circulation pump, and then promptly informs the relevant operators to promptly inspect and repair the circulation pump to avoid affecting the normal working of the thermal management integrated device.

[0056] Optionally, the alarm module can be configured as an indicator light and / or a buzzer.

By providing the first supporting boss 2113, it is convenient to reliably support the first baffle 2114.

[0058] Furthermore, a first sealing ring 24 is provided between the shell body 211 and the heat exchange baffle. The provision of the first sealing ring 24 can effectively block the gap between the shell body 211 and the first baffle 2114, prevent the heat exchange medium in the heat exchange cavity from leaking out, and ensure reliable sealing.

Specifically, by setting the first flow guide plate 2111, the heat exchange cavity and the plurality of first flow guide plates 2111 jointly form a first heat exchange flow channel 2112 arranged in an S-shaped bend, and the external heat exchange medium can enter the first heat exchange flow channel 2112 through the circulation inlet 2101, and flow out through the circulation outlet 2102 after flowing through the first heat exchange flow channel 2112, so as to circulate, and the setting of the first heat exchange flow channel 2112 can effectively extend the flow path of the heat exchange medium, so that the heat exchange medium can fully exchange heat in the heat exchange cavity, and ensure the heating effect.

[0060] Furthermore, the first guide plate 2111 is integrally formed with the shell body 211. With such a configuration, the connecting components for separate assembly between the first guide plate 2111 and the shell body 211 can be omitted, and the production and assembly time can be saved.

The fourth connecting hole 21111 is provided on the first guide plate 2111, which can make more full use of the space of the first guide plate 2111 to open holes, avoid opening holes at other positions of the shell body 211 to occupy the area of ​​the first heat exchange channel 2112, make the structural layout reasonable, and do not affect the flow path of the heat exchange medium. In addition, opening the fourth connecting hole 21111 on the first guide plate 2111 can also balance the force and reduce the deformation effect of the larger pressure in the first heat exchange channel 2112 on the shell cover 212 and the first partition plate 2114.

[0064] Optionally, the first connecting member 23 is a bolt, and the fourth connecting hole 21111 is correspondingly a threaded hole. Specifically, the bolt passes through the first connecting hole 2121, the second connecting hole 2211, the third connecting hole 21141 and the fourth connecting hole 21111 and is threadedly connected, which has a simple structure and is easy to install.

The heating element 22 is placed between the first heat exchange chamber and the second heat exchange chamber, so that the opposite sides of the heating element 22 can heat the first heat exchange chamber and the second heat exchange chamber at the same time, further increasing the effective heat exchange area of ​​the heating element 22. The heat exchange medium fully absorbs and carries the heat released by the heating element 22 during the flow process, and can further give full play to the heating effect of the heating element 22.

[0067] In addition, placing the heating element 22 between the first heat exchange chamber and the second heat exchange chamber, and filling the first heat exchange chamber and the second heat exchange chamber with heat exchange medium can adaptively balance the pressure on both sides of the heating element 22 to prevent deformation of the heating element 22 and surrounding components caused by excessive pressure on one side of the first heat exchange chamber 2111 or the second heat exchange chamber 2121.

By providing the third sealing ring 26, the gap at the junction of the first branch channel 2133 and the second branch channel 2143 can be effectively blocked to prevent leakage of heat exchange medium at the junction of the first branch channel 2133 and the second branch channel 2143.

[0075] Optionally, the material of the third sealing ring 26 is set to rubber.

[0076] Further, the first sub-shell part 213 is provided with a plurality of second guide plates 2135 at intervals on two first cavity walls opposite to the first heat exchange sub-cavity, and the plurality of second guide plates 2135 on the two first cavity walls are alternately interspersed, and the first heat exchange sub-cavity and the plurality of second guide plates 2135 together form a second heat exchange flow channel 2136 with an S-shaped bend. The second sub-shell part 214 is provided with a plurality of third guide plates 2145 at intervals on two second cavity walls opposite to the second heat exchange sub-cavity, and the plurality of third guide plates 2145 on the two second cavity walls are alternately interspersed, and the second heat exchange sub-cavity and the plurality of third guide plates 2145 together form a third heat exchange flow channel 2146 with an S-shaped bend.
