Description

Technical Field

[0001] The utility model relates to the technical field of heating structures, in particular to a heater which can be applied to automobiles. Background Art

[0002] A heater, especially an electric heater, is an electrical appliance that uses electrical energy to achieve a heating effect. Its working principle is mainly based on energy conversion, that is, converting electrical energy into thermal energy. Heaters are small in size, have high heating power, and are widely used. Heaters usually contain a heat conductor, such as metal or ceramic, which can quickly conduct heat. When the heater is connected to the power supply, current will pass through the heat conductor, causing the free electrons in the heat conductor to start moving and colliding, generating heat. Such heat will be quickly transferred to the surrounding objects or air.

[0003] Regarding the application of electric heaters, taking new energy vehicles as an example, in order to preheat the battery in low temperature areas or provide heat for the cockpit of new energy vehicles, electric heaters are usually installed in new energy vehicles. With the innovation of technology, electric heaters for new energy vehicles are gradually developing in the direction of lightweight and low cost. Electric tubular water heaters have higher heating efficiency than PTC water heaters and have cost advantages. They have been widely used in new energy vehicles.

[0004] Although the current automotive electric heating tube casting heater has high power density and relatively small size, it may have local heat dissipation that cannot be dissipated in time, resulting in high temperature. In addition, the power density of automotive electric heating tube heaters is greatly affected by the flow channel, and the flow channel design will affect the flow resistance and heat exchange efficiency of the coolant; and the current automotive electric heating tube casting heater has too many detachable connection positions for the water tank, which will also affect the sealing of the heater.

[0005] For example, in the prior art, the patent document with the publication number CN211969121U includes a water tank, a control box installed at one end of the water tank, and a water inlet and outlet provided at the other end of the water tank. An electric heating tube is provided in the water tank, and a control circuit board is provided in the control box. The electrodes of the electric heating tube are connected to the control circuit board. A water temperature sensor is also provided in the water tank, and the signal line of the water temperature sensor is connected to the control circuit board. The water temperature sensor can directly measure the temperature of the water outlet and feedback the temperature signal to the control circuit board. High and low voltage connectors are provided at the upper part of the control box. Although this structure ensures that the heater will not generate large impact currents to damage components, and the heater also has functions such as high and low voltage reverse connection prevention, over-voltage and under-voltage protection for high and low voltages, and over-current protection. The temperature sensor directly measures the temperature of the water outlet and then feedbacks the temperature signal to the control board, which can perform over-temperature protection on the product when the water temperature is too high, making the vehicle safer and more reliable. However, the electric heating tube, water temperature sensor, etc. can be detachably installed on the control box, which causes the coolant to flow into the control box through these connection positions when the water tank is filled with coolant, and thus may damage the control components in the control box.

[0006] Therefore, in the prior art, there is a technical problem that the control box is detachably connected to the internal components of the water tank, resulting in the liquid in the water tank flowing into the control box through the connection gap, and thus damaging the control components in the control box. Utility Model Content

[0007] The purpose of the present utility model is to solve the technical problem in the prior art that the control box is detachably connected to the internal components of the water tank, resulting in the liquid in the water tank flowing into the control box through the connection gap, and thus damaging the control components in the control box.

[0008] To solve the above technical problem, an embodiment of the present utility model discloses a heater, which includes a control box and a heating module provided on one side of the control box. The heating module includes a heating core body and a housing.

[0009] Wherein, the heating core body is integrally formed on the outer wall surface of the control box. One end of the housing is closed and the other end is open. The housing is sleeved on the outside of the heating core body through the opening and fixed on the outer wall surface of the control box. And a heating flow channel is formed between the inner wall surface of the housing and the outer wall surface of the heating core body, and the heating flow channel is independent of the inner cavity of the control box.

[0010] Moreover, a first water inlet and outlet communicating with one end of the heating flow channel is formed on one side wall of the housing, and a second water inlet and outlet communicating with the other end of the heating flow channel is formed on the other side wall.

[0011] With the above technical solution, when this heater is in use, the fluid to be heated enters the shell from the first inlet and outlet, and the heating element in the control box controls the heating core to release heat. The fluid entering the shell flows along the heating channel and is gradually heated by the heating core until the heated fluid flows out from the second inlet and outlet, completing the heating of the fluid. The heating core of this heater is integrally formed on the outer wall surface of the control box. When the fluid to be heated enters the shell and is heated by the heating core, the heated fluid in the shell will not flow into the control box, ensuring that the control elements in the control box are in a normal working environment, improving the reliability of the heater when heating the fluid, and extending the service life of the heater.

[0012] An embodiment of the present invention also discloses a heater. The heating core further includes a heating tube integrated inside the heating core, and the electrodes of the heating tube extend into the inner cavity of the control box.

[0013] With the above technical solution, the electrodes of the heating tube are electrically connected to the control elements in the control box, and the control elements in the control box control the heat release of the heating tube and the specific degree of heat release. Moreover, the heating tube is arranged inside the heating core, and when connected to the control elements in the control box, it will not affect the sealing performance of the shell, ensuring that the heated fluid in the shell will not flow into the control box.

[0014] An embodiment of the present invention also discloses a heater. The heating core is integrally U-shaped or planar, and a heat dissipation element is arranged on the outer wall surface of the heating core; wherein, the heat dissipation element includes heat dissipation fins and heat dissipation ribs. The heat dissipation fins are arranged on the outer wall surfaces on both sides of the heating core, and the heat dissipation ribs are arranged on the end wall surfaces of the heating core.

[0015] With the above technical solution, the U-shaped heating core structure is more compact, and on the premise of small occupied space, it increases the surface area of the heating core, improving the heating efficiency of the heating core for the fluid in the shell. The planar heating core structure is simpler and convenient for production.

[0016] Moreover, through the heat dissipation fins and heat dissipation ribs arranged on the heating core, the heat dissipation area of the heating core is further increased, improving the heating efficiency.

[0017] An embodiment of the present invention also discloses a heater. A flow channel baffle is further arranged on the outer wall surface of the heating core. The flow channel baffle protrudes from the area where the heat dissipation fins and heat dissipation ribs are located and protrudes more from the outer peripheral wall of the heating core than the heat dissipation fins and heat dissipation ribs.

[0018] Among them, the width of the flow channel gap between the outer peripheral wall of each flow channel baffle and the inner wall surface of the shell is in the range of 0.5 mm to 2 mm. And a plurality of flow channel baffles are arranged side by side in the area where the heat dissipation fins are located, and an S-shaped flow channel is formed between adjacent flow channel baffles.

[0019] Furthermore, the flow channel baffle in the area where the heat dissipation ribs are located is arranged to match the shape of the end of the heating core.

[0020] By adopting the above technical solution, multiple fluid baffles are arranged on the outer wall of the heating core, and an S-shaped flow channel is formed between adjacent flow channel baffles, which can hinder the flow speed of the fluid in the heating channel between the shell and the heating core, prolong the time for the fluid to pass through the heating channel, so that the heating core can fully heat the fluid. In addition, the flow channel baffles in the area where the heat dissipation ribs are located are arranged to match the shape of the end of the heating core, so that the flow channel gaps at various locations are equal, so that the fluid in the shell can flow in the flow channel in an orderly and smooth manner, reducing the noise generated by the fluid flowing in the shell, and avoiding turbulence of the fluid in the flow channel of the shell.

[0021] In addition, the flow channel baffle also increases the surface area of ​​the heating core, thereby improving the heating efficiency of the heater.

[0022] An embodiment of the utility model also discloses a heater, wherein each heat dissipation fin is a plate-like or step structure with wavy, serrated, or straight edges, a continuous or discontinuous structure along the extension direction, and the height of each heat dissipation fin protruding from the outer wall of the heating core is in the range of 2mm to 5mm.

[0023] Each heat dissipation rib is a plate-like or step structure with wavy, serrated, or straight edges, a continuous or discontinuous structure along the extension direction, and the height of each heat dissipation rib protruding from the outer wall of the heating core is in the range of 2mm to 5mm.

[0024] The height of each flow channel baffle protruding from the outer wall of the heating core is within the range of 10 mm to 15 mm. In addition, the heat dissipation fins extend in a direction perpendicular to the outer wall of the control box and parallel to the side extension direction of the heating core, and the heat dissipation ribs extend in a direction parallel to the outer wall of the control box and perpendicular to the side extension direction of the heating core.

[0025] By adopting the above technical solution, the heat dissipation area of ​​the heating core is increased through the heat dissipation fins, heat dissipation ribs and flow channel baffles of the above structure, which can greatly improve the heating effect of the heating core on the fluid in the shell.

[0026] The embodiment of the utility model further discloses a heater, wherein the outer wall surfaces on both sides of the heating core are respectively formed with a plurality of flow channel baffles which are staggered and evenly spaced.

[0027] By adopting the above technical solution, the flow of the fluid in the flow channel in the shell is further hindered by the multiple fluid baffles on the outer wall surfaces on both sides of the heating core, thereby extending the heating time of the heating core on the fluid in the shell.

[0028] An embodiment of the present utility model also discloses a heater, where the housing is bolted to the outer wall surface of the control box, and a sealing rubber ring is provided at the connection between the housing and the control box.

[0029] With the above technical solution, the sealing rubber ring at the connection between the housing and the control box can improve the sealing performance inside the housing, and prevent the fluid heated inside the housing from overflowing and leaking out from the connection between the housing and the control box.

[0030] An embodiment of the present utility model also discloses a heater, where a plurality of temperature sensor grooves and a temperature controller groove are further formed in the area of the outer wall surface of the control box located inside the heating flow channel. Among them, the plurality of temperature sensor grooves are symmetrically distributed with respect to the heating core, and one temperature controller groove is located at the projection center position of the heating core.

[0031] When the housing is sleeved outside the heating core, the first water inlet and outlet and the second water inlet and outlet are respectively located near the corresponding temperature sensor grooves.

[0032] With the above technical solution, the plurality of temperature sensor grooves symmetrically distributed with respect to the heating core can provide installation positions for the temperature sensors, so as to detect the fluid temperature at various places inside the housing by installing the temperature sensors, and the temperature controller groove provided at the projection center position of the heating core can provide an installation position for the temperature controller. When the heating core of the heater gets out of control, the temperature controller is used to control the heating core to stop heating.

[0033] An embodiment of the present utility model also discloses a heater, which further includes a cover plate for sealing the control box. And, a temperature sensor adapted to the temperature sensor groove is provided inside the control box.

[0034] With the above technical solution, the temperature of the fluid inside the housing can be accurately detected by using a plurality of temperature sensors.

[0035] An embodiment of the present utility model also discloses a vehicle, including any one of the above heaters.

[0036] With the above technical solution, such a vehicle can use the above heater to heat the cockpit, or a vehicle with a battery can use the above heater to preheat the battery. The heating core of this heater is integrally formed on the outer wall surface of the control box, and the fluid to be heated will not flow from inside the housing into the control box, which has a high reliability and reduces the risk of failure when the vehicle heats the interior.

[0037] The beneficial effects of the present utility model are:

[0038] The utility model discloses a heater, which comprises a control box and a heating module arranged on one side of the control box. The heating module includes a heating core body and a housing. The housing is sleeved outside the heating core body through an opening and fixed on the outer wall surface of the control box. A heating flow channel is formed between the inner wall surface of the housing and the outer wall surface of the heating core body, and the heating flow channel is independent of the inner cavity of the control box. Moreover, one side wall of the housing is formed with a first water inlet and outlet communicating with one end of the heating flow channel, and the other side wall is formed with a second water inlet and outlet communicating with the other end of the heating flow channel. The heating core body of this heater is integrally formed on the outer wall surface of the control box, and there is no gap between the heating core body and the control box, eliminating the possibility that the fluid heated in the housing flows into the control box, ensuring that the control components in the control box are in a normal working environment, improving the reliability of the heater when heating the fluid, and prolonging the service life of the heater.

[0060] A heater is a device widely used in various fields. Its main function is to convert electrical energy, fuel or other forms of energy into heat energy to achieve the heating of an object or space. Taking an electric heater as an example, the working principle of the electric heater is mainly based on the Joule heat effect generated when an electric current passes through a resistive material. When an electric current passes through an electric heating element (such as an electric heating wire, PTC ceramic, etc.), due to the existence of resistance, electrical energy will be converted into heat energy and released, thereby realizing the heating process of the surrounding medium (such as air, water, oil, etc.).

[0061] Under some specific requirements, an electric heater often needs to heat some fluid media. Taking a liquid as an example, when heating a liquid, first, the fluid and the heating material of the heater (i.e., the resistive material) need to be placed in a cavity structure. After the heating material is powered on, it emits heat and heats the liquid. However, due to the penetration characteristics of the liquid, it is easy to seep out from the cavity structure, and the seeping liquid may cause a short circuit in the external circuit connecting the heating material.

[0062] To this end, the present utility model provides a heater. A control element for controlling a heating core is arranged in the control box of this heater. The heating core is integrally formed on the outer side wall surface of the control box and is sleeved on the outer side wall surface of the control box through a housing. The fluid to be heated enters the housing, and the control element of the control box controls the heating core to generate heat so as to heat the fluid in the housing. Since there is no gap between the heating core and the outer side wall of the control box, the heated fluid in the housing will not flow into the control box, ensuring that the control element in the control box is always in a normal working environment.

[0063] To make the objectives, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0064] As Figure 1 and Figure 2 shown, an embodiment of the present utility model discloses a heater 10. This heater 10 includes a control box 100 and a heating module 200 arranged on one side of the control box 100. The heating module 200 includes a heating core 210 and a housing 220.

[0065] It should be understood that the control box 100 is provided with a control element, and the control element is electrically connected to a heat generating structure in the heating core 210 to control the heat generating structure to convert electrical energy, fuel chemical energy or other forms of energy into heat energy. Taking electrical energy as an example, a heating circuit communicating with the heat generating structure (high-resistance materials, such as electric heating wires, PTC materials, etc.) is formed in the control box 100. When the control element controls the heating circuit to be energized, the heat generating structure starts to generate electricity. Of course, heat energy can also be generated by fuel combustion. The control box 100 controls the progress of fuel combustion and selectively transfers the heat to the heat generating structure. Those skilled in the art can design according to the actual situation and specific requirements, and the present utility model does not make specific limitations. For the convenience of understanding, the heater 10 that converts electrical energy into heat energy will be described hereinafter.

[0066] Further, a plurality of control elements are arranged in the control box 100, which can specifically be other components such as a control chip, a circuit board, a switch, etc. A connection socket 140 is formed on the outer side wall surface of the control box 100 to connect the control element in the control box 100 to the overall external control unit (such as the vehicle's on-board computer). Moreover, the control box 100 and the cover plate 110 cooperate with each other to ensure that the control element in the control box 100 is in a sealed environment and prevent the control element from being damaged by other external components. Regarding the specific design of the heating circuit, the present utility model does not make specific limitations.

[0067] It should be understood that the control box 100 and the cover plate 110 can be fixedly connected by screwing, clamping or welding, and the present utility model does not make specific limitations.

[0068] Furthermore, the heating core 210 of the heating module 200 is integrally formed on the outer wall surface of the control box 100. One end of the housing 220 is closed and the other end is open. The housing 220 is sleeved outside the heating core 210 through the opening and fixed on the outer wall surface of the control box 100. A heating flow channel is formed between the inner wall surface of the housing 220 and the outer wall surface of the heating core 210, and the heating flow channel is independent of the inner cavity of the control box 100.

[0069] Moreover, a first water inlet / outlet 221 communicating with one end of the heating flow channel is formed on one side wall of the housing 220, and a second water inlet / outlet 222 communicating with the other end of the heating flow channel is formed on the other side wall. It should be noted that the first water inlet / outlet 221 and the second water inlet / outlet 222 are respectively arranged at both ends of the heating flow channel. The fluid to be heated can be injected from the first water inlet / outlet 221, flow into the heating flow channel and then flow out from the second water inlet / outlet 222, or the fluid to be heated can be injected from the second water inlet / outlet 222, flow into the heating flow channel and then flow out from the first water inlet / outlet 221. For the convenience of understanding, in the following text, the first water inlet / outlet 221 is taken as the water inlet and the second water inlet / outlet 222 is taken as the water outlet.

[0070] Further, the housing 220 is bolted to the outer wall surface of the control box 100, and a sealing rubber ring is arranged at the connection between the housing 220 and the control box 100. The sealing rubber ring at the connection between the housing 220 and the control box 100 can improve the sealing performance inside the housing 220 and prevent the fluid heated inside the housing 220 from overflowing and leaking from the connection between the housing 220 and the control box 100. Of course, the outer wall surface of the housing 220 and the control box 100 can also be fixedly connected by welding or clamping. Except for welding or other connection methods that change the material properties at the connection between the outer wall surfaces of the housing 220 and the control box 100 and directly connect the two, a sealing member needs to be arranged between the outer wall surfaces of the housing 220 and the control box 100. Of course, the sealing member is not limited to the sealing rubber ring, and can also be sealant or sealing filler.

[0071] When this heater 10 is in use, the fluid to be heated enters the housing 220 from the first water inlet / outlet 221. The heating element 210 in the control box 100 is controlled by the control element in the control box 100 to release heat. The fluid entering the housing 220 flows along the heating channel and is gradually heated by the heating element 210 until the heated fluid flows out from the second water inlet / outlet 222, completing the heating of the fluid. The heating element 210 of this heater 10 is integrally formed on the outer wall surface of the control box 100. When the fluid to be heated enters the housing 220 and is heated by the heating element 210, the heated fluid in the housing 220 will not flow into the control box 100, ensuring that the control elements in the control box 100 are in a normal working environment, improving the reliability of the heater 10 when heating the fluid, and extending the service life of the heater 10.

[0072] The structure of the heating element 210 of the heater 10 will be specifically described below.

[0073] The heating element 210 further includes a heating tube 211 integrated inside the heating element 210. The electrodes of the heating tube 211 extend into the inner cavity of the control box 100 and are electrically connected to the control elements in the control box 100. The control elements in the control box 100 control the heat release of the heating tube 211 and the specific degree of heat generation (that is, the working power of the heating tube 211 can be controlled by the control element). And the heating tube 211 is arranged inside the heating element 210. When connected to the control elements in the control box 100, it will not affect the sealing performance inside the housing 220, ensuring that the heated fluid inside the housing 220 will not flow into the control box 100.

[0074] Furthermore, in one embodiment, as Figures 1 - 6 shown, the heating element 210 is integrally U-shaped, and a heat dissipation element 214 is arranged on the outer wall surface of the heating element 210; wherein, the heat dissipation element 214 includes heat dissipation fins 215 and heat dissipation ribs 216. The heat dissipation fins 215 are arranged on the outer wall surfaces on both sides of the heating element 210, and the heat dissipation ribs 216 are arranged on the end wall surfaces of the heating element 210. By this setting method, the structure of the heating element 210 is more compact, and on the premise of small occupied space, the surface area of the heating element 210 is increased, improving the heating efficiency of the heating element 210 for the fluid inside the housing 220.

[0075] It should be noted that when the shape of the heating element 210 is U-shaped, as Figure 6As shown in the figure, when viewed along the extension direction X of the heating channel, the heating tube 211 disposed in the heating core 210 is set to be U-shaped to match it, and both ends of the heating tube 211 are electrically connected to the control components in the control box 100. Moreover, when viewed along the direction perpendicular to the extension direction X of the heating channel and the extension direction Y of the side of the heating core, the heating tube 211 extends in an S-shaped loop to increase the contact area between the heating tube 211 and the inner wall surface of the heating core 210. Of course, a plurality of heating tubes 211 can also be arranged at intervals in the direction perpendicular to the extension direction Y of the side 212 of the heating core 210, and each heating tube 211 is communicated with the control components in the control box 100. The present invention does not make specific limitations on this.

[0076] Furthermore, as shown in Figure 1 and Figure 2 when the shape of the heating core 210 is U-shaped, the shape of the housing 220 is also adapted to it. Moreover, the first water inlet / outlet 221 and the second water inlet / outlet 222 extending outward are respectively formed on both sides of the housing 220, and the structures of the first water inlet / outlet 221 and the second water inlet / outlet 222 are similar. Taking the first water inlet / outlet 221 as an example, a thread for connecting an external pipeline is formed at its end, and it is communicated with the pipeline joint for transporting fluid externally through this thread. A sealing member (such as a sealing ring) can be arranged between the first water inlet and the external pipeline. Of course, the first water inlet and the external pipeline joint can also be connected by means of clamping or interference fitting. The present invention does not make specific limitations on this.

[0077] Specifically, when the shape of the heating core 210 is U-shaped, the heating core 210 has two side parts 212 arranged at intervals, and the two side parts 212 extend along the direction perpendicular to the outer wall surface of the control box 100, and one ends of the two side parts 212 are communicated with the outer wall surface of the control box 100, and the other ends are connected through the bending part 213. It should be understood that in this embodiment, the heating flow channel is communicated from the first water inlet / outlet 221 to the second water inlet / outlet 222, and its extension direction is as shown by X in Figure 1 that is, the extension direction X of the heating flow channel is perpendicular to the extension direction Y of the side part 212 of the heating core 210. Furthermore, when the heating flow channel in the housing 220 passes through the heating core 210, it is divided into four branches by the heating core 210. Among them, two symmetrical branches are formed between the two side parts 212 and the corresponding side walls of the housing 220 respectively, and two branches are also formed between the two side parts 212 and between the bending part 213 and the corresponding side wall of the housing 220. Thus, the fluid entering from the first water inlet / outlet 221 can flow through the four branches when flowing through the heating core 210, and the heating core 210 is completely immersed in the fluid of the heating flow channel, and the heat emitted by the heating core 210 can be completely absorbed by the fluid in the heating flow channel, so that the heat emitted by the heating core 210 can be transferred to the fluid as much as possible.

[0078] Certainly, a plurality of positions are arranged at intervals in the extending direction Y of the two side portions 212 of the heating core 210 and communicate with each other to form a plurality of annular structures, and branch paths of the heating flow channel are formed in the hollow portions of each annular structure.

[0079] In another alternative embodiment, as Figures 7 - 12 shown, the heating core 210 is integrally planar, and heat dissipation elements 214 are also arranged on its outer wall surface; wherein, the heat dissipation elements 214 include heat dissipation fins 215, and the heat dissipation fins 215 are arranged on the outer wall surfaces of both sides of the heating core 210, and the heat dissipation fins 215 on both sides extend to the ends of the heating core 210 and are connected. The structure of this heating core 210 is simple, and the planar heating core 210 has a large side wall, increasing the heat dissipation area of the heating core 210, thereby improving the heating efficiency of the heating core 210 for the fluid in the housing 220.

[0080] When the heating core 210 is planar, as Figure 12 shown, the heating tube 211 arranged in the heating core 210 is located in the plane where the heating core 210 is located, and, when viewed in the direction perpendicular to the extending direction X of the heating channel and the extending direction Y of the side portion of the heating core, the heating tube 211 extends in an S shape to increase the contact area between the heating tube 211 and the inner side wall surface of the heating core 210.

[0081] Furthermore, referring to Figure 7 and Figure 8 shown, when the shape of the heating core 210 is planar, the shape of the housing 220 is also adapted thereto. And, first water inlets and outlets 221 and second water inlets and outlets 222 extending outward are respectively formed on both sides of the end of the housing 220. Regarding the structure of the water inlets and outlets, it is similar to the water inlets and outlets in the above embodiment and will not be elaborated here.

[0082] Specifically, when the heating core 210 is planar, the heating core 210 has a side portion 212, the side portion 212 extends in a direction perpendicular to the outer wall surface of the control box 100, and one end thereof communicates with the outer wall surface of the control box 100. When the heating flow channel in the housing 220 passes through the heating core 210, it is divided into three branch paths by the heating core 210. Among them, two symmetric branch paths are formed between the two sides of the side portion 212 and the corresponding side wall of the housing 220, and a third branch path is formed between the end of the side portion 212 and the corresponding side wall of the housing 220. Thus, the fluid entering from the first water inlets and outlets 221 can flow through the three branch paths when flowing through the heating core 210, the heating core 210 is completely immersed in the fluid of the heating flow channel, and the heat emitted by the heating core 210 can be completely absorbed by the fluid in the heating flow channel, so that the heat emitted by the heating core 210 can be transferred to the fluid as much as possible.

[0083] Of course, regarding the structure of the heating core 210 and the specific design of the heating flow channel, it is not limited to the above two structures only. Those skilled in the art can design according to the actual situation and specific requirements, and this embodiment does not make specific limitations thereto.

[0084] The structure of the outer surface of the heating core 210 will be described in detail below.

[0085] Specifically, for the heat dissipation fins 215 formed on the outer surface of the heating core 210, the edges thereof can be in a plate-like structure with a wavy, serrated, or straight shape. Of course, the heat dissipation fins 215 can also be in a stepped structure and can be in a continuous or discontinuous structure along the extending direction. Regarding the specific structure of the heat dissipation fins 215, the present utility model does not make a unique limitation thereto.

[0086] Furthermore, in this embodiment, the heat dissipation fins 215 extend in a direction perpendicular to the outer wall surface of the control box 100 and parallel to the extending direction Y of the side portion 212 of the heating core 210. The heat dissipation fins 215 are provided on one side of the two side portions 212 of the heating core 210 close to the housing 220, and can also be provided on the opposite side of the two side portions 212. A plurality of heat dissipation fins 215 can be evenly spaced on the two side portions 212 of the heating core 210. Regarding the number of the heat dissipation fins 215, it can be one, two, four, seven, ten, or other numbers, and the present utility model does not make specific limitations thereto.

[0087] The height by which each heat dissipation fin 215 protrudes from the outer wall surface of the heating core 210 is in the range of 2 mm to 5 mm. Specifically, the height by which each heat dissipation fin 215 protrudes from the outer wall surface of the heating core 210 can be 2 mm, 3.5 mm, 4 mm, 5 mm, or other heights within the above height range.

[0088] In addition, heat dissipation ribs 216 are also formed on the outer surface of the heating core 210, and their structures are similar to those of the heat dissipation fins 215. The edge of each heat dissipation rib 216 can be in a plate-like structure with a wavy, serrated, or straight shape. Of course, the heat dissipation fins 215 can also be in a stepped structure and can be in a continuous or discontinuous structure along the extending direction.

[0089] Furthermore, as Figures 3 - 5 shown, when the heating core 210 is U-shaped, the heat dissipation ribs 216 extend in a direction parallel to the outer wall surface of the control box 100 and perpendicular to the extending direction Y of the side portion 212 of the heating core 210, and are provided on one side of the bending portion 213 of the heating core 210 close to the housing 220, and can also be provided on the side of the bending portion 213 of the heating core 210 away from the housing 220. A plurality of heat dissipation ribs 216 can be evenly spaced on the bending portion 213 of the heating core 210.

[0090] As Figures 9 - 11 shown, when the heating core 210 is planar, the heat dissipation fins 215 extend in a direction perpendicular to the outer wall surface of the control box 100 and parallel to the extending direction Y of the side portion 212 of the heating core 210, and the heat dissipation fins 215 are arranged on two side surfaces of the side portion 212 and on the edges on both sides of the extending direction X of the heating channel.

[0091] Of course, the number of the heat dissipation ribs 216 can be one, three, four, seven, ten or other numbers, and the present utility model does not make specific limitations thereon.

[0092] The height by which each heat dissipation rib 216 protrudes from the outer wall surface of the heating core 210 is within the range of 2 mm to 5 mm. Specifically, the height by which the heat dissipation rib 216 protrudes from the outer wall surface of the heating core 210 can be 2 mm, 3 mm, 4.2 mm, 5 mm or other heights within the above height range.

[0093] It should be understood that the heat dissipation fins 215 and the heat dissipation ribs 216 provided on the heating core 210 further increase the heat dissipation area of the heating core 210 and improve the heating efficiency.

[0094] An embodiment of the present utility model also discloses a heater 10. A flow channel baffle 217 is further arranged on the outer wall surface of the heating core 210. The flow channel baffle 217 protrudes from the area where the heat dissipation fins 215 and the heat dissipation ribs 216 are located and protrudes more from the outer peripheral wall of the heating core 210 than the heat dissipation fins 215 and the heat dissipation ribs 216. It should be understood that, different from the heat dissipation fins 215 and the heat dissipation ribs 216, the flow channel baffle 217 arranged on the outer wall surface of the heating core 210 is mainly used to block the fluid from passing through the heating channel, extend the time of the fluid in the heating channel, so that the heating core 210 can heat the fluid more sufficiently. Of course, the flow channel baffle 217 can also increase the surface area of the outer wall of the heating core 210 and can play a role in improving the heating efficiency.

[0095] Wherein, the width of the flow channel gap between the outer peripheral wall of each flow channel baffle 217 and the inner wall surface of the housing 220 is within the range of 0.5 mm to 2 mm. It should be noted that the width of the flow channel gap between the outer peripheral wall of each flow channel baffle 217 and the inner wall surface of the housing 220 can be 0.5 mm, 1 mm, 1.3 mm, 1.8 mm, 2 mm or any other width within the above gap width range, and the present utility model does not make specific limitations thereon.

[0096] Moreover, a plurality of flow channel baffles 217 are arranged side by side in the area where the heat dissipation fins 215 are located, and an S-shaped flow channel is formed between adjacent flow channel baffles 217. It should be understood that the number of the flow channel baffles 217 can be one, three, five, nine, ten or other numbers, and the present utility model does not make specific limitations thereon.

[0097] The height by which each flow channel baffle 217 protrudes from the outer wall surface of the heating core 210 is within the range of 10 mm to 15 mm. It should be noted that the height by which each flow channel baffle 217 protrudes from the outer wall surface of the heating core 210 can be 10 mm, 11 mm, 13 mm, 15 mm, or any other height within the above height range. The present utility model does not make specific limitations in this regard.

[0098] On the outer wall surfaces on both sides of the heating core 210, a plurality of flow channel baffles 217 are formed which are staggered with each other and evenly spaced. The flow channel baffles 217 within the area where the heat dissipation ribs 216 are located are arranged to be adapted to the shape of the end of the heating core 210.

[0099] It should be noted that a plurality of flow channel baffles 217 are provided on the outer wall surface of the heating core 210, and an S-shaped flow channel is formed between adjacent flow channel baffles 217, which can hinder the flow velocity of the fluid in the heating channel between the housing 220 and the heating core 210, extend the time for the fluid to pass through the heating channel, and enable the heating core 210 to fully heat the fluid. Moreover, the flow channel baffles 217 within the area where the heat dissipation ribs 216 are located are arranged to be adapted to the shape of the end of the heating core 210, so that the flow channel gaps at each place are equal, enabling the fluid in the housing 220 to flow orderly and smoothly in the flow channel, reducing the noise generated by the fluid flowing in the housing 220, and avoiding the generation of turbulence of the fluid in the flow channel of the housing 220.

[0100] In addition, the flow channel baffle 217 also increases the surface area of the heating core 210, thereby improving the heating efficiency of the heater 10.

[0101] An embodiment of the present utility model also discloses a heater 10, as Figure 6 and Figure 12 shown, a plurality of temperature sensor grooves 120 and a temperature controller groove 130 are further formed in the area of the outer wall surface of the control box 100 located within the heating flow channel. Among them, the number of temperature sensor grooves 120 can be two, three, or four. Taking the number of temperature sensor grooves 120 being two as an example, the two temperature sensor grooves 120 are symmetrically distributed with respect to the heating core 210, and one temperature controller groove 130 is located at the projection center position of the heating core 210.

[0102] When the housing 220 is sleeved outside the heating core 210, the first water inlet and outlet 221 and the second water inlet and outlet 222 are respectively located at positions close to the corresponding temperature sensor grooves 120.

[0103] A plurality of temperature sensor grooves 120 symmetrically distributed relative to the heating core 210 can provide installation positions for temperature sensors, so as to detect the fluid temperature at various locations in the housing 220 by installing temperature sensors. The temperature controller groove 130 provided at the projection center position of the heating core 210 can provide an installation position for the temperature controller. When the heating core 210 of the heater 10 experiences thermal runaway (i.e., the temperature of the heating core 210 exceeds a preset temperature threshold), the temperature controller provided at the projection center position of the heating core 210 can quickly detect the temperature of the heating core 210 and cut off the connection between the heating core 210 and the external heating circuit to control the heating core 210 to stop generating heat. Among them, the temperature controller can be a temperature fuse commonly used in the art. Regarding the specific models and specifications of the temperature sensor and the temperature fuse, those skilled in the art can design according to the actual situation and specific requirements, and the present utility model does not make specific limitations in this regard.

[0104] It should be noted that the preset temperature threshold can be designed according to the actual situation of the heating core 210 and specific heating requirements, and the present utility model does not make specific limitations in this regard.

[0105] An embodiment of the present utility model also discloses an automobile, including any one of the above heaters 10.

[0106] This kind of automobile can use the above heater 10 to heat the cockpit. The heating core 210 of this heater 10 is integrally formed on the outer side wall surface of the control box 100, and the fluid to be heated will not flow from the housing 220 into the control box 100, which has a high reliability and reduces the risk of failure when the automobile heats the interior of the vehicle. Of course, when the automobile is a new energy vehicle, that is, when it has a power battery, this kind of heater 10 can also be used to preheat the battery.

[0107] The working process of the heater 10 will be described below in combination with the scenario of heating the power battery by the heater 10.

[0108] The control box 100 of this heater 10 is installed on the vehicle body through the cover plate 110, and the control components in the control box 100 are electrically connected to the total control unit on the vehicle through the connection socket 140. The first water inlet and outlet 221 on the housing 220 is communicated with the upstream pipeline of the cooling pipe, and the second water inlet and outlet 222 is communicated with the downstream pipe body of the cooling pipe, so that the coolant in the cooling pipe flows through the heater 10. When it is necessary to preheat the power battery, the control components in the control box 100 receive the electrical signal from the total control unit of the vehicle and control the heating pipe 211 in the heating core 210 to be energized with the external heating circuit. The heating core 210 starts to generate heat. The coolant entering the housing 220 from the first water inlet and outlet 221 flows towards the second water inlet and outlet 222 along the extension direction X of the heating flow path. And the temperature sensor arranged at the first water inlet and outlet 221 can detect the initial temperature of the coolant entering the housing 220.

[0109] Taking the U-shaped heating core 210 as an example, when flowing through the U-shaped heating core 210, it flows through four branches and passes through a plurality of heat dissipation fins 215 and heat dissipation ribs 216 to fully exchange heat with the heating core 210 and absorb the heat emitted by the heating core 210. And a plurality of flow path baffles 217 arranged on the heating core 210 can extend the time for the coolant to flow through the heating core 210, so that the heating core 210 transfers as much heat as possible to the coolant. The heated coolant further flows towards the second water inlet and outlet 222. The temperature sensor arranged at the second water inlet and outlet 222 can detect the temperature of the heated coolant. By taking the difference from the initial temperature of the coolant entering the housing 220, the increased temperature of the coolant can be obtained. When the increased temperature of the coolant exceeds the predetermined temperature, the working power of the heating pipe 211 is reduced; when the increased temperature of the coolant does not reach the predetermined temperature, the working power of the heating pipe 211 is increased; thus ensuring that the coolant heated by this heater 10 can meet the use requirements. Of course, the heating process of the flat heating core 210 is similar to that of the U-shaped heating core 210, which will not be elaborated here.

[0110] It should be noted that when the heating pipe 211 of the heating core 210 works for a long time and the temperature is too high and exceeds the melting point of the fuse in the temperature fuse, the fuse in the temperature fuse is disconnected, cutting off the connection between the heating pipe 211 and the heating circuit, avoiding the burning of the heating circuit or the heating pipe 211, and protecting the circuit.

[0111] And this heater 10 is not only limited to the above application in vehicles, but can also be used in other technical fields such as chemical industry, food processing, medicine, and military industry. The present utility model does not make specific limitations on this.
