Abstract
Description
Technical Field

To improve the integration (i.e., compactness) of thermal management systems, manifolds are often used to connect or interconnect the various thermal management components to form a thermal management module. However, conventional thermal management modules often lack a reasonable layout of thermal management components, resulting in low integration and a lack of compactness. Utility Model Content

[0037] Figure 1 and Figure 2 is a perspective view of a thermal management module according to an exemplary embodiment of the present invention. Figure 3 and Figure 4 They are Figure 1 The side and top views of the thermal management module are shown. For the purpose of clarity, Figure 3 and Figure 4 Coolant circuit components have been removed.
[0038] like Figures 1 to 4 As shown, the thermal management module 100 primarily comprises a refrigerant manifold 1, a compressor 2, a first (or group of) thermal management elements 3, a second (or group of) thermal management elements 4, and a coolant manifold 5. The refrigerant manifold 1 is generally flat and has a main body 10. In the front-to-back direction (i.e., thickness direction) of the main body 10 of the refrigerant manifold 1, the compressor 2 and the first (or group of) thermal management elements 3 are mounted on the same side of the refrigerant manifold 1 (i.e., the front side, also referred to as the first side or side A). The second (or group of) thermal management elements 4 and the coolant manifold 5 are mounted on the opposite side of the refrigerant manifold 1 (i.e., the rear side, also referred to as the second side or side B). The second (or group of) thermal management elements 4 include a coolant pump 41, a coolant multi-way valve 42, and / or a coolant check valve 43. A coolant flow channel (not shown) is provided in the coolant manifold 5 for fluid communication with the second (or group of) thermal management elements 4.
[0039] The first (group) of thermal management elements 3 is provided in the refrigerant circuit and includes, for example, an internal heat exchanger 31, a drying bottle 32, an electric valve 35, a first two-fluid heat exchanger 36, a second two-fluid heat exchanger 37, and / or a temperature and pressure sensor (not shown). The coolant manifold 5 is in fluid communication with the first two-fluid heat exchanger 36 and / or the second two-fluid heat exchanger 37. The "electric valve" herein may be an electronic expansion valve. The term "two-fluid heat exchanger" here means a two-fluid heat exchanger having a refrigerant (first fluid) flow channel and a coolant (second fluid) flow channel; the refrigerant and coolant exchange heat within the two-fluid heat exchanger. The first two-fluid heat exchanger 36 may be a water-cooled condenser, and / or the second two-fluid heat exchanger 37 may be a chiller.
[0040] The internal heat exchanger 31 and the first two-fluid heat exchanger 36 are respectively located at the upper and lower ends and the lower end of the left side of the refrigerant manifold 1. The area between the internal heat exchanger 31 and the first two-fluid heat exchanger 36 on the refrigerant manifold 1 is formed with a mounting joint 113 for the drying bottle 32 (see Figure 5 and Figure 7 ), which is used to be fixedly connected to and communicate with the bottom of the drying bottle 32. In order to improve the installation stability of the drying bottle 32 and the refrigerant manifold 1, a connecting piece 321 is provided between the top of the drying bottle 32 and the refrigerant manifold 1.
[0041] In addition, two temperature and pressure sensors 34 are provided on the side wall of the refrigerant manifold 1 adjacent to the installation surface of the internal heat exchanger 31 , for respectively detecting the temperature and pressure of the fluid at the inlet and outlet of the internal heat exchanger 31 .
[0042] The refrigerant manifold 1 mainly includes a refrigerant flow channel portion 11 and a support portion 12 (which will be referred to later). Figures 5 to 7 The first (group of) thermal management elements 3 are mounted on the refrigerant flow path portion 11 . A support portion 12 is adjacent to the refrigerant flow path portion 11 , and the compressor 2 is mounted on the support portion 12 .
[0043] like Figure 3 and Figure 4 As shown, the compressor 2 is installed to the right of the first (group) of thermal management elements 3. Preferably, the compressor 2 is installed so that the discharge end of the compressor 2 is farther away from the first (group) of thermal management elements 3 than the suction end of the compressor 2. Because the temperature of the discharge end of the compressor 2 is generally higher than the temperature of the suction end of the compressor 2, such an arrangement can, to a certain extent, reduce the impact of the high temperature of the compressor 2 on the first (group) of thermal management elements 3 and the fluid properties in the flow channel 114.
[0044] Fixing points 118 , 119 , 129 are provided on the outer circumference of the refrigerant manifold 1 for fixedly mounting the refrigerant manifold 1 on a base device (eg a body of a motor vehicle).
[0045] Figure 5 yes Figure 1 A perspective view of the refrigerant manifold in the thermal management module is shown. Figure 6 and Figure 7 They are Figure 5 A perspective and side view of the refrigerant manifold are shown.
[0046] like Figures 5 to 7As shown, the refrigerant flow channel portion 11 and the support portion 12 of the refrigerant manifold 1 can be an integrally formed part or an assembled part. Preferably, the support portion 12 forms a hollow structure. In addition, the refrigerant flow channel portion 11 can also form a hollow structure. The first dual-fluid heat exchanger 36 is in fluid communication with the coolant manifold 5 through the hollow structure of the refrigerant flow channel portion 11. In this way, the refrigerant flow channel portion 11 and the support portion 12 are respectively located in independent areas, which not only facilitates the structural design of the support portion 12, but also can avoid, to a certain extent, the influence of the high temperature of the compressor 2 on the fluid in the flow channel 114.
[0047] The refrigerant flow channel portion 11 includes adjacent first and second mounting surfaces 111, 112. The first mounting surface 111 generally extends along the thickness of the refrigerant manifold 1, more specifically, along a generally horizontal plane. The second mounting surface 112 generally extends along the height of the refrigerant manifold 1, more specifically, along a generally vertical plane, such that the first mounting surface 111 is generally perpendicular to the second mounting surface 112. The first (or group of) thermal management elements 3 are distributed across the first and second mounting surfaces 111, 112, to further enhance the compactness of the thermal management module 3.
[0048] The refrigerant flow channel portion 11 is provided with a plurality of threaded holes 115, through which the first (group) of thermal management elements 3 are mounted. The refrigerant flow channel portion 11 is also provided with a plurality of interfaces 116 for connecting to corresponding first (group) of thermal management elements 3. Furthermore, the refrigerant flow channel portion 11 is provided with flow channels 114 for fluid communication between the first (group) of thermal management elements 3.
[0049] The support portion 12 includes a first crossbeam 121 and a second crossbeam 123 extending from the upper and lower ends of the refrigerant flow channel portion 11, respectively, and a support beam 122 located between the first crossbeam 121 and the second crossbeam 123. When viewed along the thickness direction of the refrigerant manifold 1, that is, as shown in FIG. Figure 6 When viewed from the perspective shown, support beam 122 is generally M-shaped. This ensures the support strength of support portion 12 while reducing material requirements. The three inflection points of support beam 122 are fixedly connected to first crossbeam 121 and second crossbeam 123, respectively. Threaded holes 124 are formed at each inflection point. Compressor 2 can be mounted to support portion 12 using these threaded holes 124.
[0050] Return Reference Figure 4 .like Figure 4 As shown, in the front-to-back direction (i.e., thickness direction) of the main body 10 of the refrigerant manifold 1, the refrigerant manifold 1, the internal heat exchanger 31, and the drying bottle 32 are stacked and arranged in a sandwich structure without increasing the overall direction of the thermal management module, and satisfying the following requirements:
[0051] a≤b or a≤c
[0052] Wherein, a is the total thickness of the stack of the refrigerant manifold 1 , the internal heat exchanger 31 and the drying bottle 32 , b is the total thickness of the stack of the refrigerant manifold 1 and the first two-fluid heat exchanger 36 , and c is the total thickness of the stack of the refrigerant manifold 1 and the compressor 2 .
[0053] In this embodiment, stacking the refrigerant manifold 1, internal heat exchanger 31, and dryer bottle 32 in a sandwich structure does not increase the overall thickness of the thermal management module 3. This is because the internal heat exchanger 31 and dryer bottle 32 are relatively thin, and the total thickness (a) of the stack of the refrigerant manifold 1, internal heat exchanger 31, and dryer bottle 32 is at least less than the total thickness (b) or (c) of the stack of the first two-fluid heat exchanger 36 or the compressor 2 and refrigerant manifold 1. In contrast, if the internal heat exchanger 31 and dryer bottle 32 were arranged directly side by side on the refrigerant manifold 1, not only would the layout of the flow channel 114 on the refrigerant manifold 1 be more difficult, but the overall structure of the thermal management module 3 would also be less compact.
[0054] Figure 8 is a perspective view of a thermal management module according to another exemplary embodiment of the present invention. Figure 9 yes Figure 8 A perspective view of the refrigerant manifold in the thermal management module is shown. Figure 10 yes Figure 9 A top view of the refrigerant manifold is shown.
[0055] and Figures 1 to 7 Compared with the situation in the previous embodiment shown, Figures 8 to 10 The main feature of the refrigerant manifold in the exemplary embodiment shown is that it also includes a base 20. The main body 10 is connected to the base 20. The base 20 provides multiple fixing points 201, 202, 203, 204, and 205; these fixing points 201, 202, 203, 204, and 205 are used to mount the thermal management module 100 to a base device (not shown). It can be seen that the distribution of these fixing points 201, 202, 203, 204, and 205 provides a more stable center of gravity for the thermal management module.
[0056] It can be understood that the thermal management module according to the exemplary embodiment of the present invention is applicable to various motor vehicles.
[0057] Although the technical objectives, technical solutions, and technical effects of the present invention have been described in detail above with reference to specific embodiments, it should be understood that the above embodiments are merely illustrative and not restrictive. Within the spirit and principles of the present invention, any modifications, equivalent substitutions, and improvements made by those skilled in the art are intended to fall within the scope of protection of the present invention.
