Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of automobile heaters, in particular to an automobile heater. Background Technique

[0002] Automobile heaters can not only provide heating functions for the interior of the vehicle, enabling passengers to obtain a comfortable driving experience in cold weather, but also be combined with energy management systems and fast charging systems to achieve effective energy management and optimization. Therefore, it is required that automobile heaters can quickly transfer energy and have a high heat dissipation efficiency.

[0003] After retrieval, the Chinese patent publication number is: CN117799393B, which discloses an automobile heater, related to the field of heat dissipation of automobile heaters. The automobile heater includes: a substrate, a housing, a heater body, and a splint. The heater body is placed on the surface of the substrate away from the housing. A cavity is formed between the housing and the substrate, and the splint is placed in the cavity. The surface of the splint close to the heater body is provided with fins and a frame. The fins are used to guide the water flow passing through the splint, and the frame is used to divide the water flow passing through the splint into multiple parallel water flow circuits. In the embodiment of this application, the splint is placed in the cavity formed between the housing and the substrate, and the water flow passing through the splint can be used to dissipate heat from the heater body. The fins provided on the splint can guide the water flow passing through the splint, causing the water flow to flow through the heating area, resulting in turbulence, reducing the thermal resistance, and improving the heat dissipation efficiency of the automobile heater. The frame on the splint divides the water flow passing through the splint into multiple parallel water flow circuits, increasing the flow rate of the water flow and improving the heat dissipation efficiency. However, in actual use, although the presence of fins helps to improve the heat dissipation efficiency, it is also easy to accumulate dirt and impurities. At the same time, the water flow disturbance and noise caused by the fins are also relatively large, affecting the use effect. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an automobile heater, aiming to improve the problem that although the presence of fins in the prior art helps to improve the heat dissipation efficiency, it is also easy to accumulate dirt and impurities.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an automobile heater, including a lower housing, a cavity is opened inside the lower housing, a frame is fixedly connected inside the lower housing, a plurality of water-cooled plates are fixedly connected inside the frame, an upper housing is slidably connected to the top of the lower housing, a frame is arranged on the inner wall of the upper housing, a heating wire is fixedly connected to the top of the frame, a heat conduction sheet is fixedly connected to the top of the upper housing, and a heat storage mechanism is arranged on the inner wall of the upper housing.

[0006] Through the above technical solution: Heat is generated by the heating wire. The heat is first conducted outward through the heat-conducting sheet.

[0016] As a further description of the above technical solution:

[0017] A connector is fixedly connected to the left side of the lower shell. An air outlet is communicated with the top of the connector. The air outlet is arranged on the top of the upper shell.

[0018] Through the above technical solution: The connector provides power for the heating wire, and the air outlet effectively guides the heated air to flow out, making it flow in a specific direction and path, improving the uniformity of heat reception in the vehicle.

[0019] As a further description of the above technical solution:

[0020] Both the left and right sides of the outer wall of the frame are fixedly connected with clamping blocks, and both the left and right sides of the inner wall of the upper shell are provided with clamping grooves, and the outer walls of the clamping blocks are slidably connected to the inner sides of the clamping grooves.

[0021] Through the above technical solution: Connecting the heating wire and the upper shell through the clamping block and the clamping groove makes the heating wire detachable, facilitating maintenance and replacement.

[0022] As a further description of the above technical solution:

[0023] The outer wall of the frame is fixedly connected with a sealing ring, and the sealing ring is slidably connected to the inner wall of the lower shell.

[0024] Through the above technical solution: The sealing ring isolates the lower cavity from the heating wire, effectively improving the sealing performance of the two and ensuring the normal operation of the heating wire.

[0025] As a further description of the above technical solution:

[0026] The diameter of the rivet is adapted to the inner diameter of the through hole, and the outer wall of the rivet is made of aluminum alloy material.

[0028] The utility model has the following beneficial effects:

[0029] 1. In the utility model, the water-cooling plates arranged in a staggered and meandering manner form a water flow channel, increasing the contact time and area between the water flow and the heater, significantly improving the heat dissipation efficiency and stability of the vehicle heater. Through the circulating heat dissipation process of the water inlet and the water outlet, the heat can be conducted and taken away more quickly, effectively preventing the occurrence of local overheating.

[0030] 2. In the utility model, by arranging the phase change material inside the upper shell, the heat can be stored when the heating wire is working, and released when it stops working or the heat is insufficient, maintaining a relatively stable temperature output and improving the energy utilization efficiency.

Specific implementation manners

[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] Refer to attached Figure 1 and attached Figure 2 and attached Figure 3 In an embodiment provided by the present utility model: An automotive heater includes a lower housing 1, a cavity 5 is provided inside the lower housing 1, a frame 4 is fixedly connected inside the lower housing 1, a plurality of water-cooled plates 6 are fixedly connected inside the frame 4, an upper housing 3 is slidably connected to the top of the lower housing 1, borders 7 are provided on the inner wall of the upper housing 3, a heating wire 8 is fixedly connected to the top of the borders 7, a heat conducting sheet 9 is fixedly connected to the top of the upper housing 3, and a heat storage mechanism 2 is provided on the inner wall of the upper housing 3; a water outlet 12 is communicated with the outer wall of the lower housing 1, and a water inlet 13 is communicated with the outer wall of the lower housing 1; a connector 14 is fixedly connected to the left side of the lower housing 1, an air outlet 15 is communicated with the top of the connector 14, and the air outlet 15 is provided on the top of the upper housing 3.

[0040] Specifically, the heat-conducting fin 9 on the top of the upper housing 3 can quickly conduct the heat generated by the heating wire 8 outward, improving the heat transfer efficiency. A heat dissipation structure is provided at the bottom. Cold water enters the lower housing 1 through the water inlet 13. Through the combination of multiple staggered water-cooling plates 6, a meandering water flow channel is formed, increasing the flow time of the water in the plates, so as to more effectively absorb and carry away the heat. The heated water flows out through the water outlet 12, thus realizing the circulating flow of the water and improving the heat dissipation effect.

[0041] Refer to the appendix Figure 4 and the appendix Figure 5 As shown in the figure, a square frame 201 is fixedly connected to the inner wall of the heat storage mechanism 2. The top of the square frame 201 is fixedly connected to the inner top wall of the upper housing 3. A phase change material 202 is fixedly connected to the inside of the square frame 201. A partition plate 203 is fixedly connected to the bottom of the square frame 201. The outer wall of the partition plate 203 is fixedly connected to the inner wall of the upper housing 3. The partition plate 203 is arranged above the heating wire 8; On the left and right sides of the outer wall of the frame 7, clamping blocks 18 are fixedly connected. On the left and right sides of the inner wall of the upper housing 3, clamping grooves 17 are opened. The outer wall of the clamping block 18 is slidably connected to the inside of the clamping groove 17; A sealing ring 16 is fixedly connected to the outer wall of the frame 7. The sealing ring 16 is slidably connected to the inner wall of the lower housing 1;

[0042] Specifically, by setting the square frame 201 to accommodate the phase change material 202, the grip of the phase change material 202 is improved. When the heating wire 8 works, the phase change material 202 absorbs some excess heat and stores it, and releases it when needed, improving the utilization rate of resources. The partition plate 203 can prevent the direct contact between the upper phase change material 202 and the heating wire 8, protect the heating wire 8 and extend its service life.

[0043] Refer to the appendix Figure 1 and the appendix Figure 2 As shown in the figure, through holes 10 are opened on the outer walls of the upper housing 3 and the lower housing 1. Multiple through holes 10 are connected by rivets 11; The diameter of the rivet 11 is adapted to the inner diameter of the through hole 10. The outer wall of the rivet 11 is made of aluminum alloy material;

[0044] Specifically, by opening through holes 10 on the outer walls of the upper housing 3 and the lower housing 1 and connecting them with rivets 11, a stable structural connection is provided, ensuring that the two will not easily separate or loosen under the vibration and impact during the operation of the vehicle, and guaranteeing the overall stability of the heater.

[0045] Working principle: When the vehicle heater starts to work, the heating wire 8 is energized to generate heat. The heat is first conducted outward through the heat conduction sheet 9 at the top of the upper housing 3. At the same time, the heat in the lower housing 1 forms a water flow channel through a plurality of water cooling plates 6 fixedly connected to the inner side of the frame 4. When cold water enters the cavity 5 of the lower housing 1 from the water inlet 13, it will flow through the meandering water flow channel formed by the staggered arrangement of the water cooling plates 6. The time for the water flow to flow in the water cooling plate 6 increases, enabling it to absorb heat more effectively. Then, the hot water formed after dissipating heat flows out from the water outlet 12, realizing the heat dissipation cycle. And a heat storage mechanism is arranged above the heating wire 8, in which the phase change material 202 is encapsulated in the square frame 201. When the heating wire 8 works to generate heat, part of the heat will be transferred to the phase change material 202. The phase change material 202 will undergo a phase change after absorbing heat, thereby storing thermal energy. When the heating wire 8 stops working or the heat supply is insufficient, the phase change material 202 will release the stored heat to maintain the temperature of the heater.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
