Description

Technical Field

[0001] This utility model belongs to the application field of water heating heaters for new energy vehicles, and in particular relates to an integrated structure of a circular tube membrane heating component and a compressor. Background Technology

[0002] With the rapid development of new energy vehicles, the technological routes of their components are constantly being updated, especially in terms of integration, lightweighting, and low cost. As a core component of the thermal management system of new energy vehicles, the electric compressor plays an increasingly crucial role in the vehicle's cooling and heating processes. Currently, new energy vehicles mostly use air-heated or water-heated PTC heaters as heat sources. However, these heaters occupy a large space and have low integration, making it difficult to meet the requirements of new energy vehicle air conditioning systems for small size and light weight. Although some technologies have proposed flat-plate thick-film heating plates, this structure still requires additional cast aluminum water channels for coolant circulation, leading to increased weight and volume, higher manufacturing costs, and a certain risk of dry burning during high-power operation. In contrast, the circular tube film heating component is based on seamless steel tubes, using a screen printing process to sequentially form functional layers such as an insulating layer, a conductor layer, a resistive layer, and a top insulating layer. This not only results in a compact structure but also allows the coolant to circulate directly inside the circular tube, eliminating the need for additional cast aluminum water channels and thus reducing manufacturing costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an integrated structure of a circular tube membrane heating component and a compressor.

[0004] To solve the above-mentioned technical problems, the integrated structure of the circular tube film heating component and the compressor of this utility model includes a compressor housing and a compressor installed in the compressor housing. The compressor housing has a compressor coolant pipeline, and a section of heating pipeline is included in the compressor coolant pipeline. The heating pipeline is directly formed by the tube body of the circular tube thick film heater.

[0005] The tube body of the circular tube thick film heater consists of two parallel connected sections, one end of which is connected to the other end and extends out of the compressor housing to form the compressor coolant inlet and compressor coolant outlet.

[0006] The tube body of the circular tube thick film heater forms a flow channel for the compressor coolant, and a heat exchange spiral guide column is provided inside the flow channel.

[0007] The lower part of the compressor housing is provided with an installation cavity, and a round tube thick film heater is installed in the installation cavity.

[0008] The cylindrical thick film heater is equipped with a cast aluminum shell, and a control component is located on the upper part of the cast aluminum shell. A wiring terminal is located on the outside of the compressor, which is directly connected to the control component to achieve unified control of the compressor and the heating film assembly.

[0009] The circular tube thick film heater is sealed inside the cast aluminum housing by a sealing ring, and the bottom of the cast aluminum housing is provided with a lower cover plate for fixing the circular tube thick film heater. The space between the circular tube thick film heater and the lower cover plate is filled with insulating thermally conductive adhesive.

[0010] The terminal block is equipped with a high-voltage plug and a low-voltage plug.

[0011] The flow channel is made of stainless steel.

[0012] Advantages of this utility model: (1) The round tube thick film heater is directly assembled inside the compressor housing as the compressor coolant pipeline, which eliminates the external installation space of the traditional independent water channel heater, realizes the integrated design of compressor and heating function, and significantly reduces the overall volume; since two round tubes are connected in parallel, its power density is low, which effectively reduces the risk of dry burning and has good application prospects. (2) The flow channel of the compressor coolant is made of stainless steel and is equipped with heat exchange spiral guide column. The compressor coolant forms turbulence during the flow process, which improves the heat transfer coefficient and thus improves the overall heat exchange efficiency. (3) The upper part of the cast aluminum housing is integrated with the control components. The wiring terminals on the outside of the compressor body are directly connected to the control components, so that only one controller can be used to control the compressor and the round tube thick film heater at the same time, reducing the independent control modules and wiring, and improving the integration effect of the equipment.
