Description

Technical Field

[0001] This utility model relates to the field of automotive thermal management technology, and in particular to a compressor and thermal management system with an integrated heater. Background Technology

[0002] In a vehicle's thermal management system, both the refrigeration and heating systems play crucial roles. In traditional vehicles, the compressor and heater are distributed separately, resulting in a large space occupation and overall weight.

[0003] Furthermore, in existing vehicle-mounted heater devices, the core heating method is mostly thick-film heating. Thick-film heaters involve screen printing insulating film layers, heating resistance films, conductive dielectric films, and insulating film layers onto a stainless steel substrate, heating the coolant on the water channel side through the substrate. However, in existing thick-film heating technologies, the heating film typically only contacts and heats one side of the water channel. The surface temperature of the heating plate is relatively high, and single-sided heat exchange cannot fully utilize the heat, resulting in low heat exchange efficiency and wasted heat.

[0004] Therefore, there is an urgent need for a compressor and thermal management system with an integrated heater to solve the above-mentioned technical problems. Utility Model Content

[0051] Example 1

[0052] This embodiment provides a compressor with an integrated heater, which can integrate the compressor module and the heater module, improve space utilization, achieve double-sided heat exchange, increase the heat exchange area, and improve heat exchange efficiency.

[0053] Please refer to Figures 1 to 4Specifically, the compressor of the integrated heater includes a housing 10, a compressor unit, a heating element 20, and a circuit board. The outer casing 10 includes a first casing 11, a second casing 12, a third casing 13, and a cover plate 14. The third casing 13 is disposed between the first casing 11 and the second casing 12, and the cover plate 14 is disposed at the opening of the second casing 12. The first casing 11 and the third casing 13 enclose a first inner cavity, the second casing 12 and the cover plate 14 enclose a second inner cavity, and the second casing 12 and the third casing 13 enclose a third inner cavity. The compressor unit is disposed in the first inner cavity and is combined with the first inner cavity to form a compressor module. The heating element 20 is disposed in the middle of the second inner cavity and is surrounded by the second inner cavity to form two heat exchange channels 101. The two heat exchange channels 101 are respectively disposed on both sides of the heating element 20, and a heat exchange medium flows in the heat exchange channels 101. The heating element 20 includes a resistance layer 21 and two ceramic outer shells 22. The resistance layer 21 is used for heating, and the two ceramic outer shells 22 are respectively disposed on both sides of the resistance layer 21 and respectively contact the two heat exchange channels 101 for heat exchange. The heater module is formed by the combination of the heating element 20, the second inner cavity and the heat exchange channel 101. The circuit board is located in the third inner cavity, and the compressor unit and the heating element 20 are electrically connected to the circuit board.

[0054] In this embodiment, the compressor of the integrated heater integrates the compressor unit, heating element 20, and circuit board within the same housing 10, achieving integration of the compressor module and heater module. Both the heating element 20 and the compressor unit are electrically connected to the circuit board, allowing the compressor module and heater module to share the same circuit board. This simplifies the component structure, improves space utilization, and reduces costs. Furthermore, in the heater module, due to the heating effect of the resistance layer 21, the ceramic housing 22 on both sides of the resistance layer 21 abuts against the cavity wall of the second inner cavity, forming a heat exchange channel 101. This achieves dual-channel heat exchange, increasing the contact area between the heating element 20 and the heat exchange medium, reducing heat loss, and improving heat exchange efficiency. Simultaneously, the ceramic housing 22 improves the hardness and thermal conductivity of the heating element 20, and has good insulation properties, resulting in a high safety factor.

[0055] Please refer to Figure 1 Specifically, the first housing 11 is a cylindrical structure, while the second housing 12 and the third housing 13 are plate-shaped structures, used to match the settings of the corresponding modules.

[0056] Optionally, the first housing 11 and the third housing 13, the second housing 12 and the third housing 13, and the second housing 12 and the cover plate 14 are connected by any of the following connection methods: bolt connection, riveting connection, integral molding, etc.

[0057] Furthermore, the first housing 11 and the third housing 13, the second housing 12 and the third housing 13, and the second housing 12 and the cover plate 14 are all sealed together to prevent leakage.

[0058] Please refer to Figure 3 Optionally, a sealing element 60 is provided between the second housing 12 and the cover plate 14. By compressing the sealing element 60 between the second housing 12 and the cover plate 14, a seal between the second housing 12 and the cover plate 14 can be achieved.

[0059] Specifically, the second housing 12 has a sealing groove 123, and the sealing element 60 is partially disposed in the sealing groove 123. The sealing element 60 is compressed between the bottom of the sealing groove 123 and the cover plate 14 to achieve the sealing function of the sealing element 60.

[0060] Please return to the reference. Figure 1 Optionally, the first housing 11 is provided with an intake pipe 111 and an exhaust pipe 112. The intake pipe 111 is used to draw in low-temperature and low-pressure refrigerant. The compressor unit compresses the drawn low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant, and then discharges it through the exhaust pipe 112.

[0061] It is understandable that the compressor unit uses the common internal structure of a compressor, which will not be elaborated here.

[0062] Optionally, the circuit board and the compressor unit, as well as the circuit board and the heating element 20, are connected by electrical connection structures such as wires and busbars to achieve electrical connection between the circuit board and the compressor unit, and between the circuit board and the heating element 20. The circuit board is used to operate the compressor module and the heater module, which is a common structure in the art and will not be described in detail here.

[0063] Specifically, the resistive layer 21 is electrically connected to the power supply device, enabling the resistive layer 21 to be heated by electricity. Optionally, the resistive layer 21 is connected to the power supply device via a circuit board.

[0064] Optionally, the resistive layer 21 may be made of a resistive heating material such as a tungsten wire resistive layer or a copper wire resistive layer for heating.

[0065] Optionally, the ceramic outer shell 22 is made of ceramic materials such as aluminum nitride ceramic material and alumina ceramic material.

[0066] Please refer to Figure 1 , Figure 3 and Figure 4 Furthermore, the second shell 12 is provided with an inlet pipe 121 and an outlet pipe 122, both of which are connected to the heat exchange channel 101. The inlet pipe 121 is used for the inflow of heat exchange medium, and the outlet pipe 122 is used for the outflow of heat exchange medium, so as to realize the circulation of heat exchange medium in the heat exchange channel 101.

[0067] It is understandable that the positions of the inlet pipe 121 and the outlet pipe 122 can be adapted to actual needs, and no specific restrictions are made here.

[0068] Specifically, the second inner cavity also includes an inlet channel 102 and an outlet channel 103. The ends of the inlet channel 102 and the outlet channel 103 are respectively connected to the inlet pipe 121 and the outlet pipe 122. Both the inlet channel 102 and the outlet channel 103 are connected to the heat exchange channel 101, which allows the heat exchange channel 101 to be connected to the inlet pipe 121 and the outlet pipe 122 respectively. Furthermore, the inlet channel 102 and the outlet channel 103 can also be used to distribute and guide the heat exchange medium when it enters and exits.

[0069] Optionally, the inlet channel 102 and the outlet channel 103 can be formed by slotting the cavity wall of the second inner cavity or by other structural separations, both of which can achieve the forming of the inlet channel 102 and the outlet channel 103.

[0070] Alternatively, the heat exchange channel 101 can be formed by various structures such as flow channel plate 30, fin structure, and heat exchange structure.

[0071] Specifically, in this embodiment, the compressor with the integrated heater further includes two flow channel plates 30. The two flow channel plates 30 are respectively disposed on both sides of the heating element 20. The flow channel plates 30 are sandwiched between the cavity wall of the second inner cavity and the heating element 20 to form a heat exchange channel 101. Both heat exchange channels 101 are connected to the inlet channel 102 and the outlet channel 103. The heat exchange medium flows sequentially through the inlet channel 102, the two heat exchange channels 101, and the outlet channel 103. That is, by additionally setting the flow channel plates 30 and having them together with the cavity wall of the second inner cavity and the heating element 20 to form the heat exchange channel 101, the formation of two heat exchange channels 101 is achieved.

[0072] Specifically, the inlet pipe 121 and the outlet pipe 122 are located at both ends of the same side wall of the second housing 12. Similarly, the inlet channel 102 and the outlet channel 103 are located at both ends of the second inner cavity. The heat exchange medium first flows into the inlet channel 102 through the inlet pipe 121, then is distributed to the two heat exchange channels 101 through the inlet channel 102, where it exchanges heat with the heating element 20. It then flows into the outlet channel 103 and out through the outlet pipe 122, thus achieving heat exchange of the heat exchange medium.

[0073] Optionally, the flow channel plate 30 is a corrugated plate, that is, its cross section is corrugated. The corrugated flow channel plate 30 is tightly connected to the ceramic outer shell 22 of the heating element 20 to form a heat exchange channel 101.

[0074] Optionally, the flow channel plate 30 is made of aluminum, which has a high thermal conductivity. Of course, in other embodiments, the flow channel plate 30 may also be made of other materials, and no specific limitation is made here.

[0075] Specifically, the flow channel plate 30 is provided with multiple flow channels arranged in parallel, and the multiple flow channels arranged in parallel are connected to the inlet channel 102 and the outlet channel 103 to form a heat exchange channel 101.

[0076] In an optional embodiment, multiple flow channels extend along a first direction, which is the direction from the inlet channel 102 to the outlet channel 103, thereby enabling the multiple flow channels to connect with the inlet channel 102 and the outlet channel 103.

[0077] In another optional embodiment, multiple flow channels extend along a second direction, which is set at an angle to the first direction. This can also enable the multiple flow channels to connect with the inlet channel 102 and the outlet channel 103, and allow the heat exchange medium to flow in or out at an angle. This greatly increases the turbulence effect on the heat exchange medium, improves the uniformity of the heat exchange medium, and thus improves the heat exchange effect.

[0078] This embodiment also provides a thermal management system that includes a compressor with an integrated heater provided by any of the above-described solutions. By employing this compressor with an integrated heater, not only is the space utilization rate of the thermal management system improved, but the heat exchange efficiency during heating is also increased.

[0079] Example 2

[0080] This embodiment provides a compressor and thermal management system with an integrated heater, which is largely the same in structure as Embodiment 1, with improvements only. Therefore, only the differences between the two are described here; structures identical to those in Embodiment 1 will not be repeated. In this embodiment, the same or corresponding technical features as in Embodiment 1 are referred to by the same reference numerals. The difference between this embodiment and Embodiment 1 lies in the structure of the heater module. Specifically, the configuration of the heat exchange channel 101 is different.

[0081] Please refer to Figure 5 and Figure 6 Specifically, in this embodiment, the heating element 20 and the two flow channel plates 30 are configured as a heating assembly, and multiple sets of heating assemblies are provided. That is, within the second housing 12, multiple sets of heating elements 20 and corresponding two flow channel plates 30 are provided to achieve multi-channel heat exchange, thereby improving the heat exchange area and heat exchange efficiency.

[0082] Optionally, the flow channels in at least two flow channel plates 30 extend in different directions. This arrangement allows the heat exchange medium to flow randomly according to the different included angles between the flow channel plates 30, greatly enhancing the turbulence in the flow process and further improving the heat exchange efficiency.

[0083] This embodiment uses two sets of heating components as an example. Two of the four flow channel plates 30 have different flow channel extension directions than the other flow channel plates 30, and these two flow channel extension directions are also different. The heat exchange medium first flows into the inlet channel 102 through the inlet pipe 121, and then is distributed to the four heat exchange channels 101 through the inlet channel 102, where it exchanges heat with the heating element 20. During this process, the different extension directions of each flow channel improve the turbulence effect, increase the uniformity of the heat exchange medium, and improve the heat exchange effect. Finally, the heat exchange medium from each heat exchange channel 101 converges into the outlet channel 103, flows into the outlet pipe 122 through the outlet channel 103, and then flows out, thereby achieving heat exchange of the heat exchange medium.

[0084] Example 3

[0085] This embodiment provides a compressor and thermal management system with an integrated heater, which is largely the same in structure as Embodiment 1 or Embodiment 2, with improvements only. Therefore, only the differences between the two are described here; structures identical to those in Embodiment 1 or Embodiment 2 are not repeated. In this embodiment, the same or corresponding technical features as in Embodiment 1 or Embodiment 2 are referred to by the same reference numerals. The difference between this embodiment and Embodiment 1 or Embodiment 2 lies in the structure of the heater module. Specifically, the configuration of the heat exchange channel 101 is different.

[0086] Please refer to Figures 7 to 9 Specifically, in this embodiment, the bottom wall of the second housing 12 and the inner wall of the cover plate 14 are each provided with a plurality of turbulence-inducing columns to form heat exchange channels 101. Two heat exchange channels 101 are respectively connected to the inlet channel 102 and the outlet channel 103, and a connecting channel 43 is provided between the two heat exchange channels 101. The heat exchange medium flows sequentially through the inlet channel 102, one heat exchange channel 101, the connecting channel 43, the other heat exchange channel 101, and the outlet channel 103. This structure fully utilizes the heat exchange characteristics of both sides of the heating element 20, reducing heat loss; and the turbulence-inducing columns increase the heat exchange efficiency.

[0087] Specifically, the turbulence-disrupting columns are configured as a first turbulence-disrupting column 41 and a second turbulence-disrupting column 42. The first turbulence-disrupting column 41 is disposed on the bottom wall of the second housing 12, and the second turbulence-disrupting column 42 is disposed on the inner wall of the cover plate 14. A heat exchange channel 101 is formed by the first turbulence-disrupting column 41, the heating element 20, and the bottom wall of the second housing 12, and another heat exchange channel 101 is formed by the second turbulence-disrupting column 42, the heating element 20, and the inner wall of the cover plate 14.

[0088] Optionally, the multiple turbulence-disrupting columns can be arranged in a uniform array or staggered, both of which can achieve the functions of turbulence and forming heat exchange channels 101, and no specific limitation is made here. For example, in this embodiment, the turbulence-disrupting columns are arranged in a uniform array.

[0089] Specifically, the inlet pipe 121 and the outlet pipe 122 are arranged opposite to each other on both sides of the second shell 12, and the height of the outlet pipe 122 is higher than the height of the inlet pipe 121. The inlet channel 102 and the outlet channel 103 are located at one end of the inlet pipe 121 and the outlet pipe 122 and are separated by the heating element 20 along the height direction. A connecting channel 43 is opened at the end of the second shell 12 where the inlet pipe 121 and the outlet pipe 122 are not provided, so as to realize the connection of the two heat exchange channels 101.

[0090] The heat exchange medium first flows into the inlet channel 102 through the inlet pipe 121, and then is evenly distributed into a heat exchange channel 101 through the inlet channel 102. It exchanges heat with the heating element 20 in the heat exchange channel 101, and then flows into the connecting channel 43. It then flows into another heat exchange channel 101 through the connecting channel 43, exchanges heat with the heating element 20 in the heat exchange channel 101, and then flows into the outlet channel 103. It then flows out through the outlet pipe 122 through the outlet channel 103, thereby realizing the heat exchange of the heat exchange medium.

[0091] Optionally, a support plate 124 is also provided inside the second housing 12. The end face of the support plate 124 is higher than the end face of the first turbulence column 41. The heating element 20 is disposed on the support plate 124 to divide the second inner cavity into two layers along the height direction. Specifically, the end of the second housing 12 without the inlet pipe 121 and outlet pipe 122 is not provided with the support plate 124, so that this part is not covered by the heating element 20, thereby forming a connecting channel 43 to realize the connection of the two heat exchange channels 101.

[0092] Optionally, the heating element 20 and the support plate 124 can be fixedly connected by means of riveting or bonding.

[0093] Example 4

[0094] This embodiment provides a compressor and thermal management system with an integrated heater, which is largely the same in structure as Embodiments 1, 2, or 3, with improvements only made based on Embodiments 1, 2, or 3. Therefore, only the differences between the two are described here, and the structures identical to those in Embodiments 1, 2, or 3 will not be repeated. In this embodiment, the same or corresponding technical features as in Embodiments 1, 2, or 3 are referred to by the same reference numerals. The difference between this embodiment and Embodiments 1, 2, or 3 lies in the structure of the heater module. Specifically, the configuration structure of the heat exchange channel 101 is different.

[0095] Please refer to Figures 10 to 12 Specifically, in this embodiment, the bottom wall of the second housing 12 and the inner wall of the cover plate 14 are both provided with spiral flow channels to form heat exchange channels 101. The two heat exchange channels 101 are respectively connected to the inlet channel 102 and the outlet channel 103, and the heating element 20 has a connecting port 53 to connect the two heat exchange channels 101. The heat exchange medium flows sequentially through the inlet channel 102, one heat exchange channel 101, the connecting port 53, the other heat exchange channel 101, and the outlet channel 103. The above structure makes full use of the heat exchange characteristics on both sides of the heating element 20, reducing heat loss; and by setting two spiral flow channels, the heat exchange area of ​​the heat exchange medium is increased, improving the heat exchange efficiency.

[0096] Specifically, the inlet pipe 121 and the outlet pipe 122 are arranged opposite to each other on both sides of the second shell 12, and the height of the outlet pipe 122 is higher than that of the inlet pipe 121; the bottom wall of the second shell 12 is provided with a first spiral flow channel 51, which is connected to the inlet pipe 121 through the outer inlet channel 102 and spirals inward; the inner wall of the cover plate 14 is provided with a boss 141, and a second spiral flow channel 52 is provided on the boss 141, which is connected to the outlet pipe 122 through the outer outlet channel 103 and spirals inward; the heating element 20 is provided with a connecting port 53 in the middle, which is correspondingly provided with the first spiral flow channel 51 and the second spiral flow channel 52 to realize the connection of the two spiral flow channels, thereby realizing the connection of the two heat exchange channels 101.
