Description

Technical Field

[0001] This utility model relates to an integrated film heating system for automotive air conditioning compressors, and belongs to the technical field. Background Technology

[0002] Membrane heaters, as heat sources in vehicles, provide heat to the passenger compartment or battery, ensuring a comfortable temperature for occupants in winter and preheating the battery. Current membrane heaters have a single-sided heat exchange structure, which is ineffective for heat exchange. To meet high-power heat exchange requirements, the entire membrane heating area needs to be increased, resulting in an excessively large overall area for the membrane heater. However, vehicle space is limited, limiting the expansion of the membrane heater area and failing to meet usage requirements. Utility Model Content

[0003] The purpose of this invention is to provide an integrated membrane heater for automotive air conditioning compressors, in order to solve the technical problem that the existing membrane heaters cannot meet the high-power heat exchange requirements due to their single-sided heat exchange.

[0004] The present invention adopts the following technical solution: an integrated film heater for an automotive air conditioning compressor, comprising a heating film, the heating film including a drive control board and a heating resistor integrated on the drive control board, flow channel shells on both sides of the heating film, each flow channel shell having an internal cavity structure, each flow channel shell having a fluid inlet and a fluid outlet communicating with the cavity structure, an insulating layer fixed on the side of each flow channel shell near the heating film, the two sides of the insulating layer being respectively attached to the flow channel shell and the heating film, the heating film being sandwiched between the two insulating layers.

[0005] The shape and size of the insulating layer are the same as those of the heating film.

[0006] The side of the flow channel housing that is in contact with the insulating layer is a concave surface that fits into the insulating layer, and the insulating layer is fitted into the concave surface.

[0007] Bolt holes are arranged around the circumference of the flow channel shell, and the two flow channel shells are fixedly connected together by bolts inserted into the bolt holes.

[0008] The fluid inlet and fluid outlet are located on opposite sides of the flow channel housing, and the fluid inlet and fluid outlet on the same flow channel housing are located at opposite corners.

[0009] The fluid inlet of the first flow channel shell and the fluid outlet of the second flow channel shell are located on the same side.

[0010] The dual-phase flow channel is made of aluminum alloy.

[0011] The drive control board is a PCB board.

[0012] The beneficial effects of this invention are as follows: This invention provides flow channel shells on both sides of the heating film. During use, heating media are introduced into the flow channel shells on both sides, utilizing the bidirectional flow on both sides to exchange heat with the heating film. The heat on both sides of the heating film is fully utilized. Therefore, when the heat exchange power demand is high, it is not necessary to increase the area of ​​the heating film, thus the overall area of ​​the film heater does not need to be changed. Compared with the prior art, this invention can effectively utilize the vehicle interior space, reduce the area of ​​the film heater arrangement, and improve heat exchange efficiency.

[0013] Preferably, the shape and size of the insulating layer are the same as those of the heating film, which facilitates assembly.

[0014] Preferably, the concave surface on the flow channel housing facilitates the installation of the insulating layer, and the two insulating layers and the heating film are located precisely between the concave surfaces of the two flow channel housings, which facilitates the fixed connection after the two flow channel housings are docked.

[0015] Preferably, the two flow channel housings are fixedly connected by bolts, making the installation of the entire membrane heater very simple.

[0016] Preferably, the fluid inlet and fluid outlet are arranged opposite to each other in the flow channel shell, which makes the path of the heating medium in the flow channel shell longer and helps to improve the heat exchange efficiency. In the two flow channel shells, the fluid inlet and outlet are arranged in an alternating manner, which helps to make the temperature distribution on both sides of the heating film more uniform and the heat transfer more stable.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 4 As shown, an embodiment of the present invention discloses an integrated film heater for an automotive air conditioning compressor, comprising a heating film, a drive control board 2, and a heating resistor 3 integrated on the drive control board 2. The drive control board 2 is a PCB board. Flow channel housings 1 are respectively provided on both sides of the heating film. Each flow channel housing 1 has an internal cavity structure. Each flow channel housing 1 has a fluid inlet 1.1 and a fluid outlet 1.2 communicating with the cavity structure. An insulating layer 4 is fixed on the side of each flow channel housing 1 near the heating film. The two sides of the insulating layer 4 are respectively attached to the flow channel housing 1 and the heating film, with the heating film sandwiched between the two insulating layers 4. The shape and size of the insulating layer 4 are the same as those of the heating film.

[0024] The side of the flow channel housing 1 that is in contact with the insulating layer is a concave surface that fits into the insulating layer, and the insulating layer is fitted into the concave surface. Bolt holes 1.3 are arranged circumferentially on the flow channel housing 1, and two flow channel housings 1 are fixedly connected together by bolts inserted into the bolt holes 1.3.

[0025] The fluid inlet 1.1 and fluid outlet 1.2 are located on opposite sides of the flow channel housing 1, and the fluid inlet 1.1 and fluid outlet 1.2 on the same flow channel housing are located at opposite corners. The fluid inlet of the first flow channel housing and the fluid outlet of the second flow channel housing are located on the same side, and the fluid outlet of the first flow channel housing and the fluid inlet of the second flow channel housing are located on the same side. The flow channel housing is made of aluminum alloy.

[0026] During installation, the heating film is sandwiched between the two insulating layers. The concave surface on the flow channel housing facilitates the installation of the insulating layers. The two insulating layers and the heating film are placed between the concave surfaces of the two flow channel housings. After the two flow channel housings are joined together, bolts are used to fix the two flow channel housings together.

[0027] In this embodiment, flow channel shells are respectively provided on both sides of the heating membrane. During use, heating medium is introduced into the flow channel shells on both sides, and heat exchange is carried out on the heating membrane by bidirectional flow on both sides. The heat on both sides of the heating membrane can be fully utilized. Therefore, when the heat exchange power demand is large, it is not necessary to increase the area of ​​the heating membrane, and thus the area of ​​the entire membrane heater does not need to be changed. This utility model can effectively utilize space, reduce the area of ​​membrane heater arrangement, and improve heat exchange efficiency.

[0028] The integrated film heater for the automotive air conditioning compressor in this embodiment is installed as follows: Figure 2As shown, it is installed on the air conditioning compressor of an electric vehicle during use. The membrane heater is integrated with the compressor 5, which can effectively reduce the number of parts in the vehicle. Since the power consumption of the membrane heater is high in winter, it will increase the load pressure on the compressor drive controller. However, the compressor 5 can remove the heat generated by this load by the low-temperature refrigerant it draws in during operation. Therefore, the integration of the membrane heater with the compressor does not affect the normal operation of the compressor.

[0029] The embodiments and descriptions above are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
