Description

Technical Field

[0001] This utility model belongs to the technical field of automotive heater cores, specifically relating to an automotive heater core. Background Technology

[0002] The car heater core is a heat exchanger located in the engine compartment of a car. It is the core component of the car's heating system and is usually made of metals such as aluminum or copper or plastic. When in use, high-temperature coolant flows into the heater core's pipes. As the coolant flows through the pipes, it transfers heat to the surrounding air. The heated air is then blown into the car by a fan to provide heating inside the vehicle.

[0003] As is well known, automotive heater cores require regular maintenance during practical applications. This maintenance is mainly used to check for blockages and ensure proper sealing. Currently, most automotive heater cores lack coolant filtration capabilities and cannot filter impurities from the circulating coolant, making the heat exchange pipes prone to blockage. Since the heat exchange pipes themselves have a small diameter, this makes the descaling process for automotive heater cores more cumbersome and complex.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an automotive heater core.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide an automotive heater core that can filter impurities from the circulating coolant, thus improving the convenience of descaling the automotive heater core.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] An automotive heater core includes: multiple sets of heat exchange pipes, a circulation guide assembly, and a filter and return assembly.

[0009] The circulation guiding assembly is fixedly assembled on one side of multiple sets of heat exchange tubes. The circulation guiding assembly includes a guiding connector, a guiding limiting component, a liquid filling pipe, and a liquid draining pipe.

The liquid filling pipe is fixedly assembled on one side of the guiding connector, and the liquid draining pipe is fixedly assembled on the other side of the guiding connector.

[0010] The impurity reflux assembly is mounted on the other side of multiple heat exchange tubes. The impurity reflux assembly includes a reflux connector, a reflux limiting member, and a filter screen.

The limiting fixing plate is fixedly sleeved on the outside of the limiting box. The flow guiding connector and the flow guiding and limiting component are combined and connected by a fixed connection between the limiting fixing plate and the connecting fixing plate.

[0015] In one or more embodiments of this utility model, the sealing gasket is disposed on the side of the limiting box close to the flow guide connector. The sealing gasket ensures the sealing of the connection between the flow guide connector and the flow guide limiting member.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0032] like Figures 1 to 7 As shown, an embodiment of the present invention includes an automotive heater core comprising: multiple sets of heat exchange pipes 1, a circulation guide assembly 2, and a filter return assembly 3. In practical applications, coolant can be added and transported through the circulation guide assembly 2. The coolant added to the circulation guide assembly 2 is heat-exchanged through the multiple sets of heat exchange pipes 1 and then guided to the filter return assembly 3 for return.

[0033] Specifically, all sets of heat exchange tubes 1 are hollow, and both ends of each set of heat exchange tubes 1 are open. This facilitates the flow of coolant within the multiple sets of heat exchange tubes 1, thereby exchanging heat with the air.

[0034] like Figure 2 As shown, heat dissipation fins 4 are fixedly connected to both sides of multiple sets of heat exchange tubes 1, and the heat dissipation fins 4 are arranged in a wavy shape. The heat dissipation fins 4 can play an auxiliary role in heat exchange of the heat exchange tubes 1.

[0035] like Figures 3 to 4 As shown, the circulation guide assembly 2 is fixedly assembled on one side of multiple sets of heat exchange tubes 1. The circulation guide assembly 2 includes a guide connector 201, a guide limiting member 202, a liquid filling pipe 203, and a drain pipe 204. The guide connector 201 is fixedly connected to one end of the multiple sets of heat exchange tubes 1. The guide connector 201 and the guide limiting member 202 cooperate to form a guide cavity, which facilitates the flow and transportation of coolant added by the liquid filling pipe 203 through the guide cavity.

[0036] like Figures 3 to 4 As shown, the flow guiding connector 201 includes a flow guiding box 2011, a flow guiding plate 2012, a partition plate 2013, and a connecting and fixing plate 2014. The flow guiding box 2011 is fixedly connected to one end of multiple sets of heat exchange tubes 1, and the flow guiding box 2011 serves to assemble and fix the multiple sets of heat exchange tubes 1. The flow guiding plate 2012 is fixedly assembled inside the flow guiding box 2011. The flow guiding plate 2012 serves to limit the assembly of the multiple sets of heat exchange tubes 1 and assist the flow of coolant.

[0037] The guide plate 2012 has multiple guide holes corresponding to the heat exchange tube 1. This allows the coolant in the guide cavity to be transported to the heat exchange tube 1 along the guide holes.

[0038] like Figures 5 to 6 As shown, the partition plate 2013 is fixedly assembled in the middle of the guide plate 2012, which facilitates the partition plate 2013 dividing the guide cavity into two parts. The connecting fixing plate 2014 is fixedly sleeved on the outside of the guide connector 201. The guide connector 201 and the guide limiting member 202 are assembled by welding the connecting fixing plate 2014 to the limiting fixing plate 2022.

[0039] like Figures 3 to 4 As shown, the flow guiding and limiting component 202 includes a limiting box 2021, a limiting fixing plate 2022, and a sealing gasket 2023. The limiting box 2021 is fixedly assembled on the side of the flow guiding connector 201 facing away from the heat exchange pipe 1, and the limiting box 2021 serves to limit and guide the flow of coolant. The limiting fixing plate 2022 is fixedly sleeved on the outside of the limiting box 2021. The flow guiding connector 201 and the flow guiding and limiting component 202 are combined and connected by a fixed connection between the limiting fixing plate 2022 and the connecting fixing plate 2014.

[0040] like Figure 2As shown, the filling pipe 203 is fixedly assembled on one side of the flow guide connector 201, and coolant is added into the flow guide cavity through the filling pipe 203. The drain pipe 204 is fixedly assembled on the other side of the flow guide connector 201. The coolant in the flow guide cavity is discharged through the drain pipe 204.

[0041] like Figure 3 As shown, the sealing gasket 2023 is positioned on the side of the limiting box 2021 close to the flow guide connector 201. The sealing gasket 2023 ensures the airtight connection between the flow guide connector 201 and the flow guide limiting member 202. The limiting fixing plate 2022 has an inlet channel and a outlet channel, which are connected to the filling pipe 203 and the outlet pipe 204, respectively. This allows the coolant added by the filling pipe 203 to be transported along the inlet channel into the flow guide cavity, and allows the coolant in the flow guide cavity to be discharged along the outlet channel.

[0042] like Figures 5 to 6 As shown, the partition plate 2013 divides the flow guiding cavity into an inlet flow guiding cavity and a outlet flow guiding cavity. Half of the multiple sets of heat exchange pipes 1 are connected to the inlet flow guiding cavity, and the other half are connected to the outlet flow guiding cavity. This allows the coolant to be transported from the inlet flow guiding cavity into the heat exchange pipes 1 along the U-shape, and after being guided and filtered by the filter and return flow assembly 3, it is transported along the heat exchange pipes 1 to the outlet flow guiding cavity for discharge.

[0043] like Figures 5 to 7 As shown, the filter and reflux assembly 3 is assembled on the other side of the multiple sets of heat exchange tubes 1. The filter and reflux assembly 3 includes a reflux connector 301, a reflux limiting member 302, and a filter screen 303. The reflux connector 301 is fixedly connected to one end of the multiple sets of heat exchange tubes 1 away from the flow guiding connector 201, and the reflux limiting member 302 is fixedly assembled on the side of the reflux connector 301 away from the flow guiding connector 201. Through the cooperation of the reflux connector 301 and the reflux limiting member 302, the reflux of the coolant flowing in the multiple sets of heat exchange tubes 1 can be limited.

[0044] like Figures 5 to 7 As shown, a connecting flange 304 is fixedly connected to the side of the reflux connector 301 and the reflux limiting member 302 that are close to each other, and the pair of connecting flanges 304 are welded together. The reflux connector 301 and the filter screen plate 303 can be disassembled by welding or disassembling the connecting flanges 304.

[0045] like Figures 5 to 7 As shown, the filter screen 303 is fixedly connected to the inner bottom surface of the return flow limiting member 302. The filter screen 303 can filter impurities from the coolant, reducing the risk of blockage in the multiple heat exchange tubes 1.

[0046] like Figures 5 to 7As shown, a return flow limiting block 305 is fixedly connected to the bottom surface of the inner wall of the return flow connector 301. An assembly groove is provided on one side of the return flow limiting block 305, and the filter screen plate 303 is inserted and assembled in the assembly groove. The return flow limiting block 305 serves to limit the assembly of the filter screen plate 303 and assist in guiding the flow.

[0047] Specifically, the reflux connector 301 and the reflux limiting member 302 cooperate to form a reflux cavity. The filter screen plate 303 and the reflux limiting block 305 divide the reflux cavity into an inlet reflux cavity and an outlet reflux cavity. Half of the multiple heat exchange tubes 1 are connected to the inlet reflux cavity, and the other half are connected to the outlet reflux cavity.

[0048] In practical use, the limiting and fixing plate 2022 and the connecting and fixing plate 2014 are connected by welding, multiple sets of heat exchange tubes 1 and the guide plate 2012 are connected, multiple sets of heat exchange tubes 1 and the return connection 301 are connected, and a pair of connecting flanges 304 are connected. This allows the guide connection 201 and the guide limiting member 202 to cooperate to form a guide cavity, and the return connection 301 and the return limiting member 302 to cooperate to form a return cavity. After assembly, the guide cavity is divided into an inlet guide cavity and a outlet guide cavity by the partition plate 2013, and the return cavity is divided into an inlet return cavity and an outlet return cavity by the filter screen plate 303 and the return limiting block 305.

[0049] Subsequently, coolant can be added to the guide cavity through the filling pipe 203. The coolant is then transported into the inlet guide cavity by the inlet flow channel and then along the guide holes on the guide plate 2012 to the multiple sets of heat exchange tubes 1. After heat exchange, it is transported to the inlet return cavity. After being filtered for impurities by the filter screen plate 303, the coolant is transported to the outlet return cavity and then through the multiple sets of heat exchange tubes 1 to the drain guide cavity. Finally, it is discharged through the drain channel along the drain pipe 204, completing the coolant circulation process. By filtering impurities from the coolant, the risk of blockage in the multiple sets of heat exchange tubes 1 is reduced.

[0050] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
