Technical Field

[0001] This utility model relates to the field of compressors, and in particular to an integrated compressor. Background Technology

[0002] With the development of the automotive industry, the requirements for comfort and energy efficiency of automotive air conditioning systems are constantly increasing. As the core component of the air conditioning system, the performance of the compressor directly affects the working efficiency of the entire system. In cold environments, the refrigerant inside the compressor needs to be preheated to ensure the normal start-up and operation of the system. Therefore, the design of the internal heating device of the compressor is particularly important.

[0003] Existing automotive compressor heaters generally use thick-film heaters with stainless steel substrates. This structure presents several technical problems: First, thick-film heaters require significant installation space, making tight integration with the compressor difficult and increasing the overall system size. Second, the complex structure of thick-film heaters, involving multiple layers of materials and intricate circuit connections, not only increases manufacturing difficulty and cost but also reduces system reliability. Furthermore, the heat transfer efficiency between existing heaters and compressors is low, leading to energy waste and prolonged system start-up time.

[0004] Therefore, there is an urgent need to develop an integrated compressor with a compact structure, high integration, and high heat exchange efficiency to solve the technical problems of large space occupation and complex structure in the existing technology. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated compressor that achieves the advantages of high integration and small footprint.

[0006] This utility model is achieved through the following technical solution:

[0016] Furthermore, a plug tube is provided in the channel formed on the inner side wall of the spiral heating tube, and the two ends of the plug tube are fixed to the partition plate by connecting arms.

In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] like Figures 1 to 4 As shown, this utility model provides an integrated compressor, including a housing 1, a compression module, a heating module, and a control module 8. The housing 1 has a sealed cavity, with an input port 2 and an output port 3 communicating with the sealed cavity. The heating module includes a partition 4 and multiple heating elements. The partition 4 separates the sealed cavity into a heat exchange chamber and a heating chamber 5, which are connected. The multiple heating elements are located in the heating chamber 5. Each heating element includes a spiral heating tube 6 and an electrode portion 7 located within the spiral heating tube 6. The multiple electrode portions 7 are signal-connected to the control module 8. The heating chamber 5 receives the heat-conducting medium flowing in through the input port 2, and the heated heat-conducting medium in the heat exchange chamber is discharged through the output port 3.

[0031] By adopting a spiral heating tube structure, the heat exchange area is significantly increased. Compared with existing thick film heaters, the integrated compressor of this invention can improve the maximum power density. At the same time, by integrating the heating module inside the compressor and separating the heating chamber 5 and the heat exchange chamber by the partition 4, a high degree of integration design is achieved, which greatly reduces the space occupied by the device. In addition, the application of the special structural design of the spiral heating tube 6 improves the space utilization and heat exchange rate, making the entire system operate more efficiently.

[0032] In this embodiment, the inlet 2 is located on the first side of the housing 1, and the outlet 3 is located on the second side of the housing 1, with the first and second sides facing away from each other. The inlet 2 is used to introduce the heat transfer medium, and the outlet 3 is used to discharge the heated heat transfer medium. Preferably, the housing 1 is made of metal material, which has good sealing and pressure resistance, and can withstand the pressure generated when the compressor is working.

[0033] In this embodiment, the partition 4 is a flat plate structure, which effectively divides the sealed cavity into two parts: a heating cavity 5 and a heat exchange cavity. The heating cavity 5 is connected to the inlet 2 and is used to receive the heat transfer medium flowing in from the inlet 2; the heat exchange cavity is connected to the outlet 3 and is used to discharge the heated heat transfer medium from the outlet 3. It is worth noting that the heat transfer medium heated by the heating cavity 5 flows into the heat exchange cavity. Throughout the process, the temperature of the heat transfer medium gradually increases, which can meet different heating requirements.

[0034] In this embodiment, the spiral heating tube 6 has an overall spiral structure and is preferably made of a metal material with good thermal conductivity, so that it can quickly transfer heat to the heat-conducting medium during operation. The electrode section 7 is disposed inside the spiral heating tube 6, effectively isolating it from the heat-conducting medium, and is mainly used to generate heat. The electrode section 7 includes a positive electrode and a negative electrode, forming a current path between them. When current flows through, heat is generated to heat the spiral heating tube 6.

[0035] The compressor of this invention also includes a detection module 9, which comprises a detection element and a first temperature sensor. The fixed end of the detection tube is mounted on the partition 4, and the free end extends into the heating chamber 5. The first temperature sensor is located within the cavity of the detection tube to accurately detect the real-time temperature in the heating chamber 5. It is worth noting that the detection module 9 is signal-connected to the control module 8.

[0036] Electrode 7 is connected to control module 8 via signal, and detection module 9 is also connected to control module 8 via signal; the two work together directly. Specifically, the controller adjusts the operating power of electrode 7 based on the temperature signal detected by the temperature sensor.

[0037] In this embodiment, two spiral heating tubes 6 are provided, and the two spiral heating tubes 6 are spaced apart along the extension direction of the compressor. This is mainly to make reasonable use of the original structure of the compressor and to form a larger heating area, thereby improving heating efficiency.

[0038] In this embodiment, a plug tube 10 is disposed within the channel formed on the inner wall of the spiral heating tube 6. Both ends of the plug tube 10 are fixed to the partition plate 4 via connecting arms 11. The plug tube 10 has a cylindrical structure with a diameter smaller than the inner diameter of the spiral tube and is positioned at the center of the spiral tube. Both ends of the plug tube 10 are fixedly connected to the partition plate 4 via connecting arms 11 to ensure the stability of the plug tube 10's position. Preferably, only one plug tube 10 is provided, allowing all the spiral heating tubes 6 to pass through. This facilitates installation, and the saved space can be used to supplement the heating area of ​​the spiral heating tubes 6, resulting in better integration and compactness.

[0039] It is worth noting that by squeezing the space inside the cavity formed in the spiral heating tube 6 by the plug tube 10, the heat transfer medium can be more fully connected with the spiral heating tube 6, thereby improving heating efficiency and increasing liquid flow rate.

[0040] In this embodiment, a turbulence-inducing section 12 is provided on the inner wall of the outer shell forming the heating cavity 5, and the turbulence-inducing section 12 acts on the outer wall of the spiral heating tube 6. Preferably, the turbulence-inducing section 12 includes one or more of a turbulence-inducing column, a turbulence-inducing plate, and a corrugated plate. In this embodiment, a combination of a turbulence-inducing plate and a corrugated plate is used. The turbulence-inducing structure can break the laminar flow state of the heat-conducting medium and form turbulence, thereby enhancing the heat exchange effect between the heat-conducting medium and the spiral heating tube 6; and it can heat the heat-conducting medium at different depths, improving the uniformity of heating the heat-conducting medium.

[0041] Preferably, the spoiler 12 is integrally formed with the outer shell. This configuration saves on steps and installation time, and reduces installation difficulty.

[0042] In this embodiment, mounting slots are respectively provided on the pipes at the input port 2 and the output port 3. A second temperature sensor 13 for detecting the inlet liquid temperature and a third temperature sensor 14 for detecting the outlet liquid temperature are installed in these mounting slots. Both the second temperature sensor 13 and the third temperature sensor 14 are connected to the control module 8 via signals.

[0043] The integrated compressor operates as follows: The heat transfer medium enters the heating chamber 5 through the inlet 2, then flows through the spiral heating tube 6, where it exchanges heat with the spiral heating tube 6 heated by the electrode section 7, causing its temperature to rise. The heated heat transfer medium then enters the heat exchange chamber and is finally discharged from the outlet 3. Throughout the process, the control module 8 adjusts the operating power of the electrode section 7 in real time based on the signal from the temperature sensor to ensure that the temperature of the heat transfer medium remains within the set range.

[0044] Example 2

[0045] Based on Embodiment 1, this embodiment has three spiral heating tubes 6, all following the same direction of extension of the compressor. The three spiral heating tubes 6 are spaced apart, which aims to make reasonable use of the original structure of the compressor and to form a larger heating area, thereby improving heating efficiency.

[0046] The turbulence-disrupting structure consists of multiple wavy grooves that act on the outer surface of the spiral heating tube 6. This structure breaks the laminar flow of the heat-conducting medium, creating turbulence and enhancing the heat exchange between the medium and the spiral heating tube 6.

[0047] It should be noted that both Embodiment 1 and Embodiment 2 are types of integrated compressors.

[0048] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
