Description

Technical Field

[0001] This utility model relates to the field of heater core technology, and in particular to an expansion tube type automotive heater core. Background Technology

[0002] The expansion-tube type automotive heater core is a key component of the automotive heating system, primarily used to convert heat from the engine coolant into hot air to provide warmth to the vehicle interior. Located within the coolant circulation path, the heater core is situated within the engine's internal circulation path. When the engine is running, the coolant circulates within the engine, increasing its temperature. Some coolant flows into the heater core through a three-way valve, transferring heat to the metal surfaces of the heater core. A fan blows outside air or recirculated air from inside the vehicle across the metal surfaces of the heater core, further transferring heat to the passing air. The heated air is then delivered into the vehicle's interior through the ventilation system, providing warmth.

[0003] When a heater core is in use, dust, lint, and other impurities gradually accumulate in the gaps between its heat dissipation fins. Over time, this significantly affects heat dissipation efficiency. Existing heater cores do not have a built-in dust cleaning function, and manual disassembly and cleaning are very troublesome. Therefore, in view of the above situation, there is an urgent need to develop an expansion-tube type automotive heater core with good heat dissipation performance and the ability to quickly clean the dust between the heat dissipation fins, making it more convenient to use. This would overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide an expansion tube type automotive heater core to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An expansion-tube type automotive heater core includes a serpentine flow tube, an outer frame, heat-conducting fins, and a rapid dust removal mechanism. Two outer frames are provided, with multiple heat-conducting fins fixed between them. These fins are secured to the outside of the serpentine flow tube. Two rapid dust removal mechanisms are installed between the two outer frames, arranged vertically opposite each other. Each rapid dust removal mechanism includes a support rod, a sliding ring, a brush, and a magnetic block. Two support rods are fixed to the outer frames, and two sliding rings are slidably mounted on the two support rods. A brush is fixedly connected between the two sliding rings and inserted into the gaps between the heat-conducting fins. A magnetic block is fixed to the upper side of the brush for adsorbing it onto the outer frame. The outer frame is made of iron and has a dust discharge groove.

[0007] Preferably, the serpentine flow tube is flat, with an inlet at one end and an outlet at the other end.

[0008] Preferably, the heat-conducting fins are provided with multiple slots for the passage of the serpentine flow tube.

[0009] Preferably, both the serpentine flow tube and the heat-conducting fins are made of copper.

[0010] The beneficial effects of this utility model are as follows: When in use, the high-temperature engine coolant flows through the serpentine circulation tube, and the heat is dissipated outwards through multiple heat-conducting fins. The car's fan then blows the heat dissipated by the heat-conducting fins into the car's interior to achieve air heating. When not in use, the magnetic block adheres to the outer frame, ensuring the stability of the entire rapid dust removal mechanism. During cleaning, a person manually pulls the brush, moving it within the gaps between the multiple heat-conducting fins. The brush pushes the accumulated dust, lint, and other impurities into the dust discharge trough for discharge. In summary, this utility model offers excellent heat dissipation and can quickly clean dust between the heat dissipation fins, making it more convenient to use. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] See Figures 1-3In this embodiment of the utility model, the expansion-tube type automotive heater core includes a serpentine flow tube 1, an outer frame 2, heat-conducting fins 3, and a rapid dust removal mechanism 4. The serpentine flow tube 1 is flat, with an inlet 101 at one end and an outlet 102 at the other. The inlet 101 and outlet 102 are connected to the engine coolant circulation system via pipe joints, allowing engine coolant to pass through the serpentine flow tube 1. There are two outer frames 2, and multiple heat-conducting fins 3 are fixed between the two outer frames 2. The multiple heat-conducting fins 3 are all secured to the outside of the serpentine flow tube 1. The heat-conducting fins 3 are provided with multiple slots 301 for the serpentine flow tube 1 to pass through. Both the serpentine flow tube 1 and the heat-conducting fins 3 are made of copper, giving them good thermal conductivity. Two rapid dust removal mechanisms 4 are installed between the two outer frames 2. The rapid dust removal mechanism 4 is arranged vertically opposite each other. The rapid dust removal mechanism 4 includes: support rods 401, sliding rings 402, brushes 403, and magnetic blocks 404. There are two support rods 401 and they are fixed to the outer frame 2. There are two sliding rings 402 and they are slidably installed on the two support rods 401 respectively. A brush 403 is fixedly connected between the two sliding rings 402. The brush 403 is inserted into the gap between multiple heat-conducting fins 3. A magnetic block 404 is fixed on the upper side of the brush 403. The magnetic block 404 is used to attract the outer frame 2. The outer frame 2 is made of iron material so that the magnetic block 404 can be attracted. When not in use, the magnetic block 404 is attracted to the outer frame 2, so that the entire rapid dust removal mechanism 4 remains stable. A dust discharge groove 201 is provided on the outer frame 2, and the dust between the gaps of the multiple heat-conducting fins 3 is discharged from the dust discharge groove 201.

[0019] Working principle: When in use, the high-temperature engine coolant passes through the serpentine flow tube 1 and dissipates the heat from the serpentine flow tube 1 to the outside through multiple heat-conducting fins 3. The car fan blows the heat dissipated by the heat-conducting fins 3 into the car to achieve air heating. When not in use, the magnetic block 404 is attracted to the outer frame 2, so that the entire rapid dust removal mechanism 4 remains stable. When cleaning, the brush 403 is pulled by hand to move within the gaps between the multiple heat-conducting fins 3. The brush 403 pushes the dust, lint and other impurities accumulated in the gaps to the dust discharge trough 201 for discharge.

[0020] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
