Description

Fluid heating heater

[0001] The present invention relates to a fluid heating heater, and more particularly, to a fluid heating heater for heating a fluid such as coolant circulating inside a vehicle.

[0002] With the trend toward environmentally friendly industrial development and the development of energy sources that replace fossil fuels, the most notable areas in the automotive industry today are electric vehicles, hybrid vehicles, and fuel cell vehicles. However, unlike vehicles powered by conventional petroleum-fired engines, these vehicles either cannot or are difficult to utilize cooling water-based heating systems.

[0003] In other words, vehicles powered by conventional petroleum-powered engines generate significant amounts of heat. Coolant circulation systems are typically installed to cool these engines, and the heat absorbed by the coolant is used to heat the interior. However, electric vehicles, hybrid vehicles, and fuel cell vehicles do not generate as much heat as engines, limiting the utility of these conventional heating methods.

[0004] Accordingly, various studies are being conducted on electric vehicles, hybrid vehicles, and fuel cell vehicles, including adding heat pumps to the air conditioning system to allow them to serve as heat sources, or installing separate heat sources such as electric heaters. Electric heaters are currently widely used, as they can heat coolant more easily and without significantly impacting the air conditioning system.

[0005] Among existing fluid heaters, a single heater is used to simultaneously supply coolant for battery and indoor heating at different target temperatures. These dual-type fluid heaters may feature multiple heating elements to supply coolant at different target temperatures. However, thermal interference between the multiple heating elements can reduce thermal efficiency and impair heater performance.

[0006] One embodiment of the present invention provides a fluid heating heater in which a partition slot is formed in a corresponding portion between a first heating element and a second heating element to prevent unnecessary thermal interference between the first heating element and the second heating element, thereby increasing heat transfer efficiency.

[0007] In addition, one embodiment of the present invention provides a fluid heating heater that can effectively prevent thermal interference at an inlet portion because the partition slot is formed close to an inlet portion through which fluid flows.

[0008] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned herein will be clearly understood by those skilled in the art from the description below.

[0009] A fluid heating heater according to one embodiment of the present invention comprises a main body having a first flow path and a second flow path formed therein through which a fluid is introduced and heated; a first heating element disposed on one surface of the main body having the first flow path formed therein and heating the first flow path; and a second heating element disposed on one surface of the main body having the second flow path formed therein and heating the second flow path, wherein the main body corresponding to the first heating element and the second heating element may be formed to be partitioned.

[0010] A partition slot may be formed in the above main body to prevent thermal interference between the first heating element and the second heating element.

[0011] The above-mentioned compartment slot can be formed by recessing inwardly on one side of the main body.

[0012] The above-mentioned compartment slots can be formed by recessing inwardly on one side and the other side of the main body, respectively.

[0013] The main body may be provided with an inlet for fluid to flow into the first flow path and the second flow path; and an outlet for fluid to flow out of the first flow path and the second flow path.

[0014] The inlet may include a first inlet through which fluid flows into the first flow path; and a second inlet through which fluid flows into the second flow path; and the outlet may include a first outlet through which fluid flows out from the first flow path; and a second outlet through which fluid flows out from the second flow path.

[0015] The above-mentioned partition slot may be formed long along one side of the first heating element and the second heating element.

[0016] The above-mentioned partition slots may be formed in multiple numbers spaced apart along one side of the first heating element and the second heating element.

[0017] The above plurality of compartment slots may be formed so that their widths become narrower as they move away from the inlet.

[0018] The above-mentioned partition slot can be formed only in a portion close to the inlet.

[0019] The above-mentioned compartment slot may be formed so that its width becomes narrower as it moves away from the inlet.

[0020] The first inlet and the first outlet may be arranged on the same side of the main body, and the second inlet and the second outlet may be arranged on the same side of the main body as the first inlet and the first outlet.

[0021] The first inlet and the first outlet may be arranged on the same side of the main body, but may be arranged on a side of the main body that is parallel to the partition slot, and the second inlet and the second outlet may be arranged on an opposite side of the main body from the first inlet and the first outlet.

[0022] The first inlet and the first outlet may be arranged on a side of the main body having a relatively short length or a side of the main body having a long length, and the second inlet and the second outlet may be arranged on a side of the main body having a relatively short length or a side of the main body having a long length.

[0023] The first inlet and the first outlet may be arranged on the same side of the main body, but may be arranged on a side of the main body that is parallel to the partition slot, and the second inlet and the second outlet may be arranged on an opposite side of the main body from the first inlet and the first outlet.

[0024] The first inlet and the first outlet may be arranged on a side of the main body having a relatively short length or a side of the main body having a long length, and the second inlet and the second outlet may be arranged on a side of the main body having a relatively short length or a side of the main body having a long length.

[0025] The first inlet and the first outlet may be arranged on the same side of the main body, and the second inlet and the second outlet may be arranged on opposite sides of the main body from the first inlet and the first outlet.

[0026] The above-mentioned partition slots can be formed in a portion close to the first inlet and a portion close to the second inlet, respectively.

[0027] The above-mentioned compartment slot may be formed so that its width becomes narrower as it moves away from the first inlet and the second inlet.

[0028] The main body includes a heating plate on which the first and second filaments are formed; and a cover plate coupled to cover the heating plate, wherein the partition slot is formed by being recessed inward from the surface of the heating plate, and the heating plates are spaced apart from each other and can be formed by being recessed inwardly into the cover plate.

[0029] According to one embodiment of the present invention, a partition slot is formed in a corresponding portion between the first heating element and the second heating element in the main body, thereby preventing unnecessary thermal interference between the first heating element and the second heating element, thereby increasing heat transfer efficiency.

[0030] In addition, according to one embodiment of the present invention, since the partition slot is formed close to the inlet portion through which the fluid flows in, thermal interference at the inlet portion can be effectively prevented.

[0042] The present invention is susceptible to various modifications and embodiments, and specific embodiments are illustrated and described in detail in the drawings. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention. In describing the present invention, detailed descriptions of related known technologies will be omitted if they are deemed to obscure the gist of the present invention.

[0043] Terms such as first, second, etc. may be used to describe various components, but these components should not be limited by these terms. These terms are used solely to distinguish one component from another.

[0044] The terminology used in this application is only used to describe specific embodiments and is not intended to limit the present invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In this application, it should be understood that the terms "comprises" or "has" indicate the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, but do not preclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0045] Additionally, throughout the specification, when we say "connected," this does not only mean that two or more components are directly connected, but also that two or more components are indirectly connected through other components, that they are electrically connected as well as physically connected, or that they are referred to by different names depending on location or function but are one.

[0046] Hereinafter, one embodiment of a fluid heating heater according to the present invention will be described in detail with reference to the attached drawings. In describing with reference to the attached drawings, identical or corresponding components are assigned the same drawing numbers and redundant descriptions thereof will be omitted.

[0047] FIG. 1 is a cross-sectional view illustrating a fluid heating heater according to one embodiment of the present invention, FIG. 2 is a view illustrating one side of a fluid heating heater according to one embodiment of the present invention on which a heating element is arranged, FIG. 3 is a view illustrating one side of a fluid heating heater according to another embodiment of the present invention on which a heating element is arranged, and FIG. 4 is a view illustrating one side of a fluid heating heater according to still another embodiment of the present invention on which a heating element is arranged.

[0048] As shown therein, a fluid heating heater according to one embodiment of the present invention includes a main body (1) in which a first flow path (22) and a second flow path (24) are formed, through which a fluid is introduced and heated, a first heating element (40) disposed on one surface of the main body (1) in which the first flow path (22) is formed and heats the first flow path (22), and a second heating element (42) disposed on one surface of the main body (1) in which the second flow path (24) is formed and heats the second flow path (24), and the main body (1) corresponding to the first heating element (40) and the second heating element (42) may be formed to be partitioned.

[0049] Here, the fact that the main body (1) is formed in a compartment means that the first heating element (40) and the second heating element (42) are physically separated from each other, thereby preventing unnecessary thermal interference between the first heating element (40) and the second heating element (42) and increasing heat transfer efficiency.

[0050] In one embodiment, a partition slot (30) may be formed in the main body (1) to prevent thermal interference for physical separation between the first heating element (40) and the second heating element (42).

[0051] The main body (1) forms the overall appearance of the fluid heating heater, and the main body (1) can be formed in a roughly flat rectangular shape. The main body (1) can include a heating plate (10) on which fluid heating is substantially performed, and a cover plate (20) coupled to cover the heating plate (10).

[0052] A plurality of flow paths (26) may be arranged in rows and columns on the surface of the heating plate (10). In addition, the first fluid flow path (22) and the second fluid flow path (24) may be formed substantially along the lines flowing between the flow paths (26). The flow paths (26) are arranged in a plurality of rows and columns as described above, and the flow paths (26) arranged in the same row and column among the flow paths (26) may be arranged to have a constant interval. When the flow paths (26) are arranged in this manner, the fluid flow path formed between the fluid inlets (11, 13) and the fluid outlets (12, 14) may have isotropy. Meanwhile, the flow paths (26) are merely presented as an example to form the first fluid flow path (22) and the second fluid flow path (24), and may also form the first fluid flow path (22) and the second fluid flow path (24) in the form of a partition wall.

[0053] Referring to FIG. 2, the main body may be provided with an inlet (11, 13) through which fluid flows into the first flow path (22) and the second flow path (24), and an outlet (12, 14) through which fluid flows out from the first flow path (22) and the second flow path (24). At this time, the inlet (11, 13) may include a first inlet (11) through which fluid flows into the first flow path (22), and a second inlet (13) through which fluid flows into the second flow path (24), and the outlet (12, 14) may include a first outlet (12) through which fluid flows out from the first flow path (22), and a second outlet (14) through which fluid flows out from the second flow path (24).

[0054] The main body (1) can be broadly divided into two regions based on the partition slot (30). In the first region, fluid can flow into the first inlet (11), flow through the first flow path (22), and then flow out through the first outlet (12), and in the second region, fluid can flow into the second inlet (13), flow through the second flow path (24), and then flow out through the second outlet (14).

[0055] The first inlet (11) and the first outlet (12) may be provided on the same side of the main body (1). Accordingly, the fluid introduced into the first inlet (11) may be heated while flowing through the first flow path (22) and then may be discharged through the first outlet (12) located on the side of the first inlet (11). Of course, the positions of the first inlet (11) and the first outlet (12) shown in this drawing are merely examples, and the first outlet (12) may be located on a different side from the side where the first inlet (11) is provided.

[0056] The second inlet (13) and the second outlet (14) may be provided on the same side of the main body (1). Accordingly, the fluid introduced into the second inlet (13) may be heated while flowing through the second flow path (24) and then may be discharged through the second outlet (14) arranged on the side of the second inlet (13). Of course, the positions of the second inlet (13) and the second outlet (14) shown in this drawing are merely examples, and the second outlet (14) may be arranged on a different side from the side where the second inlet (13) is provided. In addition, the second inlet (13) and the second outlet (14) may be provided on the same side of the main body (1) as the first inlet (11) and the first outlet (12).

[0057] A first heating element (40) and a second heating element (42) may be arranged on one surface of a heating plate (10) on which a first flow path (22) and a second flow path (24) are formed. The first heating element (40) heats a fluid flowing in the first flow path (22), and the second heating element (42) heats a fluid flowing in the second flow path (24). Although not specifically shown in this drawing, the first heating element (40) and the second heating element (42) may be controlled by separate control units. In this way, since the first heating element (40) and the second heating element (42) can be controlled by a single control unit, cost reduction, space efficiency, and weight reduction are possible.

[0058] The heating plate (10) may be made of a metal material to receive heat from the first heating element (40) and the second heating element (42), and aluminum or stainless steel may be used. In one embodiment, the first flow path (22) may supply coolant for heating the battery, and the second flow path (24) may supply coolant for heating the vehicle's interior. Of course, the coolant supplied to the first flow path (22) and the second flow path (24) may vary depending on the target, and what is important is that the coolant is supplied at different target temperatures.

[0059] In addition, the flow rates of the coolant supplied to the first flow path (22) and the second flow path (24) may be supplied differently. In one embodiment, the flow rate of the coolant supplied to the second flow path (24) may be greater than the flow rate of the coolant supplied to the first flow path (22), and in this case, the area where the second flow path (24) is formed may have a larger volume than the area where the first flow path (22) is formed.

[0060] Additionally, in one embodiment, the first heating element (40) and the second heating element (42) can heat the fluid with different heat values. That is, as shown in this drawing, the second heating element (42) can have a larger area so as to have a higher heat value.

[0061] The partition slot (30) can be formed by being recessed inward on one side of the main body (1). The partition slot (30) is formed in a corresponding portion between the first heating element (40) and the second heating element (42), thereby preventing unnecessary thermal interference between the first heating element (40) and the second heating element (42), thereby increasing heat transfer efficiency. In other words, the partition slot (30) is formed between the first flow path (22) in which the first heating element (40) is arranged and the second flow path (24) in which the second heating element (42) is arranged, thereby serving to partition the first flow path (22) and the second flow path (24).

[0062] More specifically, the partition slot (30) is recessed inward from the surface of the main body (1), but can be substantially completely spaced apart from the heating plates (10), and the shape of being recessed inward can be formed only in the cover plate (20). That is, in the process of forming the partition slot (30) as shown in FIG. 1, the portion of the partition slot (30) corresponding to the first heating element (40) and the second heating element (42) is completely spaced apart. Of course, this is merely presented as an example, and the partition slot (30) may also be formed by being recessed inward from one surface of the heating plate (10).

[0063] Referring to FIG. 2, the partition slot (30) may be formed long along one side of the first heating element (40) and the second heating element (42). That is, the partition slot (30) is formed long along the side where the first heating element (40) and the second heating element (42) are adjacent to each other. At this time, the partition slot (30) may be formed over the entire side length of the first heating element (40) and the second heating element (42). When the partition slot (30) is formed over the entire side length of the first heating element (40) and the second heating element (42) in this way, thermal interference can be fundamentally blocked.

[0064] In this way, when the partition slot (30) is formed between the first heating element (40) and the second heating element (42), the heat transferred from the first heating element (40) and the second heating element (42) to the first flow path (22) and the second flow path (24) does not interfere with each other and heat transfer between them is prevented, so that the thermal efficiency is increased and the performance can be improved. When the partition slot (30) described above is formed between the first heating element (40) and the second heating element (42), its shape and number can be set in various ways. Hereinafter, various embodiments of the partition slot (30) will be described.

[0065] Referring to FIG. 3, the partition slot (30) can be formed only in a portion close to the inlet (11, 13). That is, in the present embodiment, unlike the embodiment illustrated in FIG. 2, the partition slot (30) is not formed over the entire side length of the first heating element (40) and the second heating element (42), but is formed only in a portion close to the inlet (11, 13).

[0066] This is because a lot of heat transfer occurs at the inlet (11, 13) portion where the fluid flows in, so this portion is intensively blocked to prevent thermal interference. In one embodiment, the partition slot (30) may be formed only in a portion close to the first inlet (11) and the second inlet (13), as shown in Fig. 3. That is, the partition slot (30) may be formed only in a portion close to the inlet (11, 13) where the fluid flows in.

[0067] Here, the fact that the partition slot (30) can be formed only in the part close to the inlet (11, 13) means that the partition slot (30) starts to be formed in the part close to the inlet (11, 13) and extends along the side of the first heating element (40) and the second heating element (42). In one embodiment, the partition slot (30) can start to be formed in the part close to the inlet (11, 13) as in FIG. 3 and extend to about half of the entire side length of the first heating element (40) and the second heating element (42).

[0068] Referring to Fig. 4, the partition slot (30) may be formed to have a width that becomes narrower as it moves away from the portion closer to the inlet (11, 13). This is because, as in the embodiment illustrated in Fig. 3, a large amount of heat transfer occurs in the portion of the inlet (11, 13) where the fluid flows in, so this portion is intensively blocked to prevent thermal interference.

[0069] In other words, the width of the partition slot (30) is thickened in the part close to the inlet (11, 13) where there is relatively more thermal interference, and the width of the partition slot (30) is thinned in the part far from the inlet (11, 13) where there is relatively less thermal interference.

[0070] FIGS. 5 to 9 are drawings showing one side of a fluid heating heater according to another embodiment of the present invention on which a heating element is arranged.

[0071] Referring to FIG. 5, a plurality of partition slots (30) may be formed spaced apart from each other along the side surfaces of the first heating element (40) and the second heating element (42). FIG. 5 illustrates that three partition slots (30) are formed spaced apart from each other along the side surfaces of the first heating element (40) and the second heating element (42), but this is not limited thereto, and two or four or more partition slots (30) may be formed. When a plurality of partition slots (30) are formed spaced apart from each other in this way, thermal interference between the first heating element (40) and the second heating element (42) can be prevented at various locations.

[0072] Referring to FIG. 6, a plurality of partition slots (30) are formed spaced apart from each other along the side surfaces of the first heating element (40) and the second heating element (42), and the plurality of partition slots (30) may be formed so that their widths become narrower as they move away from the part closer to the inlet (11, 13).

[0073] In this drawing, a total of three partition slots (30) are provided, and the partition slot (30) closest to the inlet (11, 13) may be formed to have the widest width and the partition slot (30) furthest from the inlet (11, 13) may be formed to have the narrowest width. This embodiment is a combination of the embodiment illustrated in FIG. 3 and the embodiment illustrated in FIG. 4, and since a lot of thermal interference occurs on the side of the inlet (11, 13), the thickness of the partition slot (30) close to the inlet (11, 13) is made relatively thick.

[0074] Referring to Fig. 7, the first inlet (11) and the first outlet (12) may be arranged on the same side of the main body (1), and the second inlet (13) and the second outlet (14) may be arranged on the opposite side of the main body (1) from the first inlet (11) and the first outlet (12). That is, with reference to Fig. 7, the first inlet (11) and the first outlet (12) may be arranged on the upper side of the main body (1), and the second inlet (13) and the second outlet (14) may be arranged on the lower side of the main body (1). Of course, the positions of the first inlet (11) and the first outlet (12), and the positions of the second inlet (13) and the second outlet (14) may be arranged opposite to each other.

[0075] Even if the first inlet (11) and the first outlet (12) are arranged in opposite directions to the second inlet (13) and the second outlet (14), the partition slot (30) can be formed over the entire side length of the first heating element (40) and the second heating element (42).

[0076] Referring to Fig. 8, the partition slots (30) may be formed only in the portions close to the inlets (11, 13). That is, in the present embodiment, unlike the embodiment illustrated in Fig. 7, the partition slots (30) are not formed over the entire side length of the first heating element (40) and the second heating element (42), but are formed only in the portions close to the inlets (11, 13). That is, one partition slot (30) may be formed in the portion close to the first inlet (11), and one may be formed in the portion close to the second inlet (13).

[0077] Referring to Fig. 9, the partition slot (30) may be formed only in a portion close to the inlet (11, 13), similar to the embodiment illustrated in Fig. 8. However, in the present embodiment, the partition slot (30) may be formed so that its width becomes narrower as it moves away from the portion close to the inlet (11, 13). This is to prevent thermal interference by focusing on blocking this portion, since a large amount of heat transfer occurs in the portion of the inlet (11, 13) through which the fluid flows.

[0078] FIG. 10 is a cross-sectional view illustrating a fluid heating heater according to another embodiment of the present invention.

[0079] Referring to FIG. 10, a fluid heating heater according to another embodiment of the present invention may include a main body (1) in which a first flow path (22) and a second flow path (24) are formed, through which a fluid is introduced and heated, a first heating element (40) disposed on one surface of the main body (1) in which the first flow path (22) is formed and heats the first flow path (22), and a second heating element (42) disposed on one surface of the main body (1) in which the second flow path (24) is formed and heats the second flow path (24). In addition, a partition slot (30) is formed in the main body (1) corresponding to the space between the first heating element (40) and the second heating element (42) to prevent thermal interference, and the partition slot (30) may be formed by being recessed inwardly on one surface and the other surface of the main body (1), respectively.

[0080] In the embodiment illustrated in FIG. 1, the partition slot (30) is formed by recessing inwardly only on one side of the main body (1), but in the present embodiment, the partition slot (30) may be formed by recessing inwardly on one side and the other side of the main body (1), respectively. The partition slot (30) may be formed by appropriately adjusting the depth at which it is recessed into the one side and the other side of the main body (1). For example, the partition slot (30) may be formed by having a deep depth on one side of the main body (1), that is, the side where the heating plate (10) is arranged, and having a shallow depth on the other side of the main body (1), that is, the opposite side.

[0081] At this time, the shape in which the partition slot (30) is formed can be applied in the same manner to various embodiments of the partition slot (30) illustrated in FIGS. 2 to 9.

[0082] FIGS. 11 to 14 are drawings showing one side of a fluid heating heater according to another embodiment of the present invention on which a heating element is arranged.

[0083] Referring to Fig. 11, the first inlet (11) and the first outlet (12) may be arranged on the same side of the main body (1), but may be arranged on the side of the main body (1) that is arranged parallel to the partition slot (30). The second inlet (13) and the second outlet (14) may be arranged on the opposite side of the main body (1) from the first inlet (11) and the first outlet (12). The second inlet (13) and the second outlet (14) may also be arranged on the side of the main body (1) that is arranged parallel to the partition slot (30).

[0084] That is, based on Fig. 11, the first inlet (11) and the first outlet (12) may be arranged on the left side of the main body (1), and the second inlet (13) and the second outlet (14) may be arranged on the right side of the main body (1).

[0085] The first inlet (11) and the first outlet (12) may be arranged on a side of the main body (1) that has a relatively short length. In addition, the second inlet (13) and the second outlet (14) may be arranged on a side of the main body (1) that has a relatively short length.

[0086] Additionally, the positions of the first inlet (11) and the first outlet (12) and the positions of the second inlet (13) and the second outlet (14) may be arranged opposite to each other as in Fig. 12.

[0087] Referring to Fig. 13, the first inlet (11) and the first outlet (12) may be arranged on a side of the main body (1) that has a relatively long length. In addition, the second inlet (13) and the second outlet (14) may be arranged on a side of the main body (1) that has a relatively long length.

[0088] Additionally, the first inlet (11) and the first outlet (12) may be arranged on the same side of the main body (1), but may be arranged on a side of the main body (1) that is parallel to the partition slot (30). The second inlet (13) and the second outlet (14) may be arranged on the opposite side of the main body (1) from the first inlet (11) and the first outlet (12). The second inlet (13) and the second outlet (14) may also be arranged on a side of the main body (1) that is parallel to the partition slot (30).

[0089] That is, based on Fig. 13, the first inlet (11) and the first outlet (12) may be arranged on the upper side of the main body (1), and the second inlet (13) and the second outlet (14) may be arranged on the lower side of the main body (1).
