Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive heater with a flow channel structure. Background Technology

[0002] Traditional gasoline-powered vehicles heat the interior by exchanging heat generated by the engine with heat from the engine. New energy vehicles, however, lack an engine and its associated structures, so their interior heating methods differ from those of gasoline-powered vehicles. Since the optimal operating temperature for the battery pack is 20℃~35℃, the heating management system of new energy vehicles needs to provide heat not only to the passenger compartment but also to the battery pack in cold conditions.

[0003] The heating management system of new energy vehicles generally heats the coolant and circulates it through pipes to designated locations to complete the heating process. During this circulation, a heater is needed to further heat the coolant. Existing heaters typically consist of a housing containing a heating element that heats the coolant sealed within. However, most existing heaters use simple straight or S-shaped guide vanes for flow guidance. This method, due to the bending angle and flow channel width, often results in high flow resistance and large flow dead zones. These dead zones have low flow efficiency, making it difficult for coolant to flow out, ultimately leading to low heat exchange efficiency.

[0004] Secondly, air inevitably fills the heater's interior. The air flowing in the channel can easily create an air film between the coolant and the heating plate, preventing the coolant in some areas from contacting the heating plate and further reducing heat exchange efficiency.

[0012] The fourth guide vane is L-shaped, and the two fourth guide vanes are respectively located on the outer side of the front and rear sections of the third guide vane;

[0013] The heights of the first, second, third, and fourth guide vanes are not all the same; the heights of the first, second, and third auxiliary guide vanes are not all the same.

Detailed Implementation

[0029] This utility model provides an automotive heater with a flow channel structure, including a heater housing 1, on which a heating plate 2 is mounted. The heating plate 2 can be fixed around its perimeter using screws or the like. Cover plates can also be provided at both ends of the heater housing 1. The two cover plates can be fixed to the heater housing with screws or bolts, clamping the heater housing between the two cover plates, which can protect the heating plate and provide a sealing effect. A turbulence column 17 is provided inside the water chamber, which can also make the water flow more uniform at the arc-shaped section.

[0030] A sealing structure 3 is provided between the heating plate 2 and the heater housing 1. The sealing structure 3 includes a sealing groove and a sealing ring. The sealing groove is located on the inner side of the heater housing 1 and on the central platform 6, allowing the sealing ring to be installed at the contact point between the heating plate 2 and the heater housing 1 for overall sealing. The heater housing 1 is equipped with an inlet 4 and an outlet 5, both of which are connected to pipe fittings 15 for direct connection to other pipes. The area between the inlet 4 and the outlet 5 is the water chamber of the heater. A central platform 6 is located in the middle of the water chamber, providing central support and ensuring more even stress distribution and better stability of the heating plate 2 after installation. Screws or other fasteners can also be installed on the central platform 6 to fix the heating plate 2 in place.

[0031] The water chamber cavity is equipped with a flow guiding structure, which includes a first flow guiding vane 7, a second flow guiding vane 8, a third flow guiding vane 9, and a fourth flow guiding vane 10. The first flow guiding vane 7 is an arc-shaped flow guiding vane located between the liquid inlet 4 and the central platform 6. There is a certain gap between the right side of the first flow guiding vane 7 and the water chamber cavity, which facilitates the flow of coolant from the side.

[0032] The inner arc direction of the first guide vane 7 is the tail section of the second guide vane 8 and the head section of the third guide vane 9. The inner arc direction of this utility model is the direction towards the center of the arc or the center of the circle. The second guide vane 8 surrounds the outside of the central platform 6, and the middle and tail sections of the second guide vane 8 together form a U-shaped structure.

[0033] The front section of the third guide vane 9 has a U-shaped structure, and the rear section of the second guide vane 8 is located inside the front section of the third guide vane 9; the middle and rear sections of the third guide vane 9 surround the outside of the second guide vane 8. The fourth guide vane 10 is L-shaped, and the two fourth guide vanes 10 are respectively located outside the front and rear sections of the third guide vane 9.

[0034] To further improve the airflow guiding effect and reduce blind spots, a first auxiliary airflow guiding plate is provided inside the U-shaped structure at the front section of the third airflow guiding plate 9, and the first auxiliary airflow guiding plate is located outside the second airflow guiding plate 8. A second auxiliary airflow guiding plate and a third auxiliary airflow guiding plate are provided between the rear section of the third airflow guiding plate 9 and the second airflow guiding plate 8, wherein the second auxiliary airflow guiding plate is located inside the third auxiliary airflow guiding plate, and the length of the third auxiliary airflow guiding plate is longer than that of the second auxiliary airflow guiding plate.

[0035] The heights of the first guide vane 7, the second guide vane 8, the third guide vane 9, and the fourth guide vane 10 are not all the same; the heights of the first auxiliary guide vane 11, the second auxiliary guide vane 12, and the third auxiliary guide vane 13 are not all the same.

[0036] In this invention, the coolant enters through the inlet 4 and is first diverted at the first guide vane 7. Most of the coolant flows from the outside of the first guide vane 7 into the area where the second guide vane 8 is located, while a small amount of coolant passes through the side wall of the first guide vane 7 and the water chamber cavity. Due to the arc-shaped structure of the second guide vane 8 and its interaction with the central platform 6, the coolant is diverted by the third guide vane 9 when it passes the tail section of the second guide vane 8. A portion of the coolant enters the inner arc direction of the third guide vane 9 and flows from the third guide vane 9 into the outlet 5 direction; the other portion of the coolant flows from the area between the third guide vane 9 and the first guide vane 7 into the fourth guide vane 10 and is diverted by the fourth guide vane 10. Meanwhile, since the tail section of the third guide vane 9 is equipped with two auxiliary guide vanes, the flow blind zone area can still be reduced even when the length of the third guide vane 9 is relatively long. Because the third auxiliary guide vane is outside the second auxiliary guide vane, its length needs to be even longer, and it also needs to guide the coolant at the arc of the third guide vane 9. This further necessitates a longer length of the third auxiliary guide vane to solve the aforementioned problem. Two fourth guide vanes 10 are positioned around the third guide vane 9, enabling flow guidance in the outer area and further reducing the formation of blind zones, thereby achieving the effect of improving flow efficiency and heat exchange efficiency as described in this invention.

[0037] In an optimized embodiment of this invention, a temperature sensor 14 is installed inside the water chamber.

[0038] In the optimized embodiment of this utility model, the height of the first auxiliary guide vane 11 and the second auxiliary guide vane 12 is 6mm, the height of the front end of the third auxiliary guide vane 13 is 7.8mm, and the height of the rear end is 6mm; the height of the first guide vane 7 and the second guide vane 8 is 7.8mm, the height of both ends of the third guide vane 9 is 6mm, the height of the middle part is 7.8mm, and the height of the fourth guide vane 10 is 6mm.

[0039] In the optimized embodiment of this utility model, a U-shaped channel is provided between the inner wall of the water chamber and the outer side of the second guide plate 8, and a gas guide groove 16 is formed after the heating plate 2 is placed on top of the U-shaped channel.

[0040] Although specific embodiments of this utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
