Description

Technical Field

[0001] This utility model belongs to the technical field of automotive heat exchangers, and particularly relates to a heat exchanger. Background Technology

[0002] Heat exchangers are widely used in automotive temperature control systems, where they achieve heat exchange of flowing media through heat exchange fins. The structure of a heat exchanger mainly includes a heat exchange shell and heat exchange fins housed within it. The heat exchange shell has an inlet connecting to an inlet pipe and an outlet connecting to an outlet pipe. The medium flows into the heat exchange shell from the inlet pipe, undergoes heat exchange through the heat exchange fins, and then flows out from the outlet pipe. Because the inlet and outlet arrangements of the medium on the housing or enclosure of a gearbox, engine, or electric drive differ, and the inlet and outlet settings on the traditional heat exchanger base plate are consistent with the heat exchanger's inlet and outlet channels, a die-cast component is used to convert the medium channels to match the inlet and outlet on the gearbox, engine, or electric drive housing or enclosure. Traditionally, the heat exchanger base plate and the die-cast component are bolted together, and a sealing ring is used to seal between them before assembly onto the gearbox, engine, or electric drive housing or enclosure. This process involves relatively many parts, increased weight, larger volume, low space utilization, and high cost. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a heat exchanger that reduces parts and processes, lowers costs and improves space utilization.

[0004] The purpose of this utility model is achieved through the following technical solution: A heat exchanger includes a heat exchanger core, with an inlet channel and an outlet channel respectively provided within the core. A heat exchanger base plate is fixedly mounted on the core and mounted on a housing base plate for mounting the heat exchanger. The base plate has a medium inlet channel and a medium outlet channel respectively. One end of the medium inlet channel communicates with the inlet channel on the core and the other end communicates with the medium inlet on the housing base plate. One end of the medium outlet channel communicates with the outlet channel on the core and the other end communicates with the medium outlet on the housing base plate.

[0005] The beneficial effects of this utility model are as follows: Compared with the prior art, the heat exchanger base plate with the flow channel is directly installed on the heat exchanger core and directly installed with the box base plate. This not only meets the requirements of heat exchanger airtightness and performance and the customer's shell and box medium inlet and outlet arrangement, but also reduces parts and processes, saves space and reduces weight.

[0006] Preferably, both the medium inlet channel and the medium outlet channel are elongated channel structures; by setting the channel to an elongated shape, the effective flow path of the medium is greatly shortened during the flow process, thereby improving the flow efficiency.

[0007] Preferably, the outer contour shape of the heat exchanger base plate is consistent with the outer contour shape of the box base plate; through the above structure, the heat exchanger base plate and the box base plate can be better integrated after installation, resulting in better overall integrity and better sealing performance after welding.

[0008] Preferably, both the heat exchanger base plate and the housing base plate are provided with a number of mounting holes for mounting the heat exchanger onto the housing; by providing mounting holes and using bolts, the heat exchanger can be directly mounted onto the housing or casing of the gearbox, engine, or electric drive, which facilitates installation.

[0009] Preferably, the heat exchanger base plate is provided with at least two positioning holes, and the bottom of the heat exchanger core and the top of the box base plate are provided with positioning protrusions corresponding to the positioning holes; by providing positioning holes and positioning protrusions, the heat exchanger base plate can be positioned with the bottom of the heat exchanger core and the box base plate during the assembly process, which facilitates subsequent welding and fixing.

[0010] Preferably, the heat exchanger base plate is fixed to the housing base plate by welding, and the heat exchanger core is fixed to the heat exchanger base plate by welding. By first fixing the heat exchanger base plate to the housing base plate by welding, and then fixing the heat exchanger core to the heat exchanger base plate, the die-casting parts, sealing rings, and bolts are eliminated, saving space, improving space utilization, reducing the number of parts and processes, reducing product weight, saving costs for customers, and allowing customers to freely arrange the medium inlet and outlet on the shell and housing.

[0011] Preferably, a Z-shaped mounting block is installed on the top of the heat exchanger core, and the mounting block has a strip-shaped mounting hole; this allows the heat exchanger core to be installed on the housing or casing of the gearbox, engine, or electric drive via the heat exchanger base plate and the housing base plate, and then the Z-shaped mounting block is installed to fix the heat exchanger core to the engine compartment, thereby providing further stability and reinforcement.

One end of the medium inlet channel 21 communicates with the inlet channel 11 on the heat exchanger core 1, and the other end of the medium inlet channel 21 communicates with the medium inlet 31 provided on the box base plate 3. One end of the medium outlet channel 22 communicates with the outlet channel 12 on the heat exchanger core 1, and the other end of the medium outlet channel 22 communicates with the medium outlet 32 ​​provided on the box base plate 3. The traditional structure, where the base plate 2 of the heat exchanger with a flow channel is welded to the base plate 3 of the housing (corresponding to the customer's shell and medium inlet / outlet), replaces the traditional structure where the base plate is bolted to the die-cast parts and sealed with a sealing ring. The heat exchanger base plate 2 can be replaced and corresponding flow channels opened according to the arrangement of the medium inlet 31 and medium outlet 32 ​​on the housing base plate 3. This eliminates the need for die-cast parts, sealing rings, and bolts, saving space, improving space utilization, reducing the number of parts and processes, and reducing product weight, thus saving costs for the customer.

[0020] A Z-shaped mounting block 6 is installed on the top of the heat exchanger core 1, and the mounting block 6 has a strip-shaped mounting hole 61.

[0021] The installation process of this utility model is as follows: First, a corresponding heat exchanger base plate 2 is manufactured according to the housing base plate 3 on the gearbox, engine, or electric drive housing; then, the heat exchanger base plate 2 is welded and fixed to the bottom of the housing base plate 3 and the heat exchanger core 1; finally, the welded heat exchanger is fixed to the gearbox, engine, or electric drive housing or housing by bolt assembly and through the mounting hole 4.
