Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present invention. Furthermore, the accompanying drawings of the present invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated in advance. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0021] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0022] Please see Figure 1-4 This embodiment describes a small-volume, high-sealing compressor. The compressor has a first end and a second end disposed opposite to each other. The small-volume, high-sealing compressor includes: Cylinder 1, wherein a controller base plate 11 is mounted on the second end side of the cylinder 1; Heater assembly 2, which includes a housing 21 and a heating plate 22. The housing 21 is installed on one side of the second end of the controller base plate 11 and forms a heating cavity 211 for the flow of heat-conducting medium. The heating plate 22 is installed on the first end of the heating cavity 211 and seals the heating cavity 211. The housing 21 is configured as an integrally formed structure, and the heating plate 22 is welded to the housing 21 to achieve a seal. The housing 21 is provided with an integrally formed turbulence structure 212 protruding towards the heating cavity 211. The turbulence structure 212 is used to turbulent the heat-conducting medium entering the heating cavity 211.

[0023] In the above embodiments, specifically, the housing 21 is changed from a conventional die-cast part to a one-piece sheet metal structure, eliminating the middle shell structure and significantly reducing the size and weight of the heater. Specifically, in existing conventional compressor heaters, the outer shell and the heating chamber directly used for the flowing heating medium are generally separate structures, while in this embodiment, the housing 21 is a separate structure. At the same time, the heating plate 22 and the housing 21 abandon the traditional rubber gasket and achieve a highly reliable seal by direct welding. In the vehicle environment, rubber gaskets are prone to loosening and aging under vibration and shaking conditions, and leakage may occur within a certain lifespan, while the welded structure is more robust.

[0024] In other words, in the solution of this invention, a high level of sealing performance can be ensured while significantly reducing the product's volume and weight by employing an integrally formed sheet metal structure housing 21 and a welding sealing process for the heating plate 22. Specifically, in this solution, the traditional middle shell component is eliminated, significantly reducing the overall volume, weight, material, and manufacturing costs of the heater, resulting in a smaller overall longitudinal thickness and a thinner heater assembly 2. Simultaneously, by directly welding instead of using a traditional sealing gasket, the gap between the housing 21 and the heating plate 22 is effectively filled, significantly improving the sealing performance. Thanks to the integrally formed structure, the flow-disrupting structure 212 is also integrally formed with the housing 21 body, resulting in a smaller volume.

[0025] In the specific design of the heating cavity 211, the number of the turbulence-disrupting structures 212 is set to multiple, and the multiple turbulence-disrupting structures 212 are arranged in a rectangular array or staggered in the heating cavity 211. The turbulence-disrupting structure 212 is a protruding structure extending towards the heating plate 22. The cross-section of the protruding structure is one or more combinations of triangle, trapezoid, rectangle, circle, semicircle, and polygon. The protruding structure is formed by pressing the second end face of the shell towards the first end face. Specifically, in this embodiment, the turbulence-disrupting structure 212 is a trapezoidal block structure extending towards the heating plate 22. The trapezoidal block structure is formed by pressing the second end face of the shell 21 towards the first end face. Specifically, the turbulence structure 212 is essentially a series of convex structures formed by sheet metal stamping. It is mainly used to turbulent the heat-conducting medium flowing through the heating cavity 211, so that the heat-conducting medium such as water or antifreeze can roll and mix between different layers, thereby significantly improving the uniformity of the heating temperature of the heat-conducting medium and avoiding the generation of local overheating or dead water areas. The array arrangement described above can maximize the coverage of the cross-sectional area through which the heat-conducting medium flows.

[0026] In the above embodiments, the turbulence structure 212 is also integrally stamped from the shell 21, eliminating the need for additional internal welding of baffles, thus saving processing steps. It also ensures the structural continuity of the bottom of the shell. Its trapezoidal block structure is provided with inclined surfaces, which better balances the flow guiding effect and cost.

[0027] The controller motherboard 111, used for controlling the operation of the system, is installed in the controller base plate 11 and is electrically connected to the heating plate 22 through the wiring terminal 112.

[0028] In the specific design of the housing 21, the sidewalls of the housing 21 are provided with a first tube 23 and a second tube 24. The first tube 23 and the second tube 24 are welded to the housing 21, and the tubular space formed by the first tube 23 and the second tube 24 is connected to the heating chamber 211. The first tube 23 and the second tube 24 are located at opposite ends of the housing 21, and their orientations are parallel to each other. The first tube 23 and the second tube 24 serve as inlet and outlet pipes for the heat transfer medium, and are also connected to the housing 21 by welding to replace traditional threaded or flange seals, resulting in a better sealing effect. In terms of optimizing the pipeline layout, the axial orientations of the first tube 23 and the second tube 24 are parallel to each other, which means that after the heat transfer medium enters from one end, it must traverse the entire length of the heating chamber 211 before flowing out from the other end, maximizing the residence time and heat absorption area of ​​the medium inside the chamber.

[0029] Furthermore, in the installation of the heating plate 22, a connecting step 213 is provided on the first end face of the housing 21, and the edge of the heating plate 22 is attached to and welded to the connecting step 213. During assembly, the edge of the heating plate 22 is precisely embedded and attached to the connecting step 213, and then welded at this point. Through this stepped overlapping design, the solder can effectively fill the gap between the sheet metal housing and the heating plate, thereby providing extremely excellent and long-lasting pressure-resistant sealing performance.

[0030] Furthermore, a temperature sensor 25 is installed on the heating plate 22. The temperature sensor 25 protrudes and extends into the heating cavity 211 from its second end. Specifically, the mounting tube of the temperature sensor 25 is fixed by welding or threaded connection, and its probe part protrudes into the medium from its second end in the direction of the heating cavity 211, so as to accurately sense the real-time temperature of the flowing medium and provide accurate basis for the control of the controller.

[0031] Given the reduction in overall heater volume after eliminating the middle shell, and the resulting thinner overall structure, the heater assembly 2 also includes a heat insulation pad 26. The heat insulation pad 26 is attached to the first end face of the heating plate 22 and serves to block heat transfer between the heating plate 22 and the controller side. The heat insulation pad 26 can protect electronic components despite the significantly shortened heat transfer distance, cutting off the heat dissipation path from the heat-generating parts to the controller and forcibly blocking heat conduction, thereby effectively reducing the probability of overheating damage to the controller. Its coverage area is comparable to that of the heating plate.
