Problems to be solved by the invention
In an electrical apparatus for a vehicle, a design concept of fail safe (fail safe) is indispensable, and a countermeasure for avoiding the worst situation when a failure occurs due to a failure, an erroneous operation, or an erroneous operation is required. From such a viewpoint, if an obstacle that may occur in a heat medium heating device for a vehicle is assumed, the probability of occurrence is low, but it is necessary to previously assume that the heater may be out of control in the case where a control system or a sensor (thermal sensor) fails in a vehicle accident or the like.
If the heater is out of control, the heat medium becomes abnormally high temperature, and therefore, it is assumed that the heat medium cannot be sealed any more because of thermal damage or deformation of the heater cover forming the flow passage of the heat medium. In such a case, the worst situation is that the heat medium, which is a liquid, is in contact with the power supply system of the heater, but if it is assumed that the power supply system of the heater is sealed waterproof, a countermeasure for avoiding or limiting the leakage of the heat medium in the vehicle is required.
There is a concern that leakage of the heat medium may adversely affect electronic equipment in the vehicle, but when the heat medium is a coolant, the engine cannot be cooled any more, and therefore the adverse effect may be applied to the traveling of the vehicle. Therefore, it is required to suppress or limit leakage of the heating medium even when the heating medium becomes abnormally high temperature due to runaway of the heater or the like.
The present invention addresses such a situation, and an object thereof is to provide a vehicle heat medium heating device with higher safety from the viewpoint of failsafe.

In the vehicle heat medium heating device, it is preferable that the sealing structure of the heater power supply unit is provided on an upper side of the heater case, and the heater case protection unit is provided on a lower side of the heater case.
In the vehicle heat medium heating device, it is preferable that the heater case protector is a container that stores the heat medium that has flowed out of the heater case.
In the vehicle heat medium heating device, it is preferable that the heater case protection part has a volume smaller than a capacity of a temporary storage tank provided in a circulation path of the heat medium.
In the vehicle heat medium heating device, it is preferable that the volume of the heater case protection part is smaller than a difference capacity between a minimum water amount of the temporary storage tank and a water amount of the temporary storage tank in a state where air enters a circulation path of the heat medium.
In the vehicle heat medium heating device, it is preferable that the heater case protector has a discharge hole for discharging the stored heat medium in a specific direction.
In the vehicle heat medium heating device, it is preferable that the sealing structure of the heater power supply unit includes a power supply unit cover surrounding the heater power supply unit; a seal portion is formed at the peripheral edge portions of the power supply portion cover and the heater case.

Detailed Description
Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the following description, the same reference numerals in different drawings denote parts having the same functions, and overlapping descriptions in the respective drawings are appropriately omitted. In the drawings, the X-Y-Z direction is shown as a plane direction, and the Z direction is a vertical direction.
The embodiments shown here are illustrative for embodying the technical idea of the present invention, and do not limit the present invention. Further, other embodiments, examples, operation techniques, and the like that can be implemented by those skilled in the art without departing from the scope and spirit of the present invention are all included in the scope and spirit of the present invention, and are included in the invention recited in the claims and the equivalent scope thereof.
Further, the drawings attached to the present specification are merely examples, and the present invention is not limited to the explanation, although the drawings may be schematically illustrated by appropriately changing the scale, the aspect ratio, the shape, and the like from the actual ones for the convenience of illustration and understanding.
The heat medium heating device 1 according to the embodiment of the present invention is a device that heats a heat medium that circulates through an air conditioning heat exchanger (heater core) of a vehicle air conditioning device, and may be any of an engine car, an EV car, a hybrid car, and the like as a vehicle. The heating medium heating device 1 can be used as an auxiliary heat source in a vehicle having a heat source in addition to an engine vehicle, such as an EV vehicle, and can be used as a heat source for temperature control for cooling and heating in a vehicle not having a heat source. The heating medium heated by the heating medium heating device 1 is not limited to the coolant, and water, oil, or the like is an object.
As shown in fig. 1 to 3, the heating medium heating apparatus 1 includes: a heater 20; a heater case 10 that houses the heater 20 and heats the heat medium therein; a heater power supply unit 30 for supplying power to the heater 20; and a heater case protecting part 40 protecting the heater case 10.
In the illustrated example, the heater 20 includes a pair of cylindrical 1 st heating element 21 and 2 nd heating element 22; the heater case 10 includes: an upper case 11 having a 1 st accommodation recess 11 a; and a lower case 12 having a 2 nd accommodating recess 12 a; a1 st heating element 21 and a 2 nd heating element 22 are accommodated in a space formed by the combination of the 1 st accommodating recess 11a and the 2 nd accommodating recess 12 a.
In the illustrated example, the heater case 10 is provided with an inflow portion 13 and an outflow portion 14. The inflow portion 13 has an inflow port 13a through which the heating medium flows into the heater case 10; the outflow portion 14 has an outflow port 14a through which the heat medium heated in the heater case 10 flows out.
A heater support portion 16 is provided inside the heater case 10 accommodating the heater 20; a gap between the outer peripheral surface of the heater 20 (the 1 st heating element 21, the 2 nd heating element 22) supported by the heater support portion 16 and the inner surface of the heater case 10 serves as a heating medium flow path 15 through which a heating medium flows. In the example shown in the figure, the heating medium flow path 15 has the 1 st flow path 15A formed around the 1 st heating element 21, the 2 nd flow path 15B formed around the 2 nd heating element 22, and the 1 st flow path 15A and the 2 nd flow path 15B communicate with each other at the end opposite to the end of the heater case 10 where the inflow portion 13 and the outflow portion 14 are provided.
The heater power supply unit 30 is a device constituting a power supply system of the heater 20, and includes a substrate 33 to which an electronic component 31 and the like are connected. The wiring of the power supply terminal 35 is connected to the substrate 33, and the power supply line to the heater 20 is connected thereto. In the illustrated example, the substrate 33 of the heater power supply unit 30 is provided on the heater case 10, and the upper case 11 of the heater case 10 includes the substrate support unit 17 that supports the substrate 33. In the illustrated example, a heat sink (heat sink) 32 for cooling the electronic component 31 is provided on the upper case 11 of the heater case 10.
The heater case 10 is provided with a seal structure of the heater power supply unit 30. In the illustrated example, a seal structure is formed on the upper case 11, and the seal structure includes a power supply portion cover 34 surrounding the heater power supply portion 30 on the upper case 11.
The sealing structure of the heater power supply unit 30 is not limited to such an example. As another example, another sealing member (an O-ring, a liquid gasket, or the like) may be interposed between the upper case 11 and the heater power supply unit 30, or the heater power supply unit 30 itself may be molded with a sealing material.
The heater case protector 40 is a device for trapping the heater case 10 thermally damaged at the time of an abnormally high temperature of the heating medium or the heating medium flowing out of the heater case 10, and is formed of a protective cover 41 in the illustrated example. The protective cover 41 (heater case protective portion 40) is formed of a member having a higher heat-resistant temperature than the heater case 10. Specifically, in the case where the heater case 10 is formed of a resin material, the protective cover 41 is formed of a metal material (metal plate) or the like.
In normal use, the protective cover 41 can function as a heat insulating layer by forming a double structure by covering a part of the heater case 10. In order to actively obtain such a function, it is preferable to use a material (e.g., a ceramic material) having high heat resistance and high heat insulation property for the protective cover 41. By thus causing the protective cover 41 to function as a heat insulating layer, the heating performance of the heat medium heating device 1 in normal use can be improved.
Further, the power supply section cover 34 and the protective cover 41 of the heater case protective section 40 form a seal structure with the heater case 10. In this case, in the illustrated example, the power supply section cover 34 as a seal structure of the heater power supply section 30 is provided on the upper side of the heater case 10, and the protection cover 41 of the heater case protection section 40 is provided on the lower side of the heater case 10.
Fig. 4 is an enlarged cross-sectional view showing the power supply section cover 34 and the seal portion T of the protection cover 41. The seal portion T is formed at the peripheral portions of the power supply portion cover 34 and the upper case 11, and at the peripheral portions of the protective cover 41 and the lower case 12. The heater case 10 is formed by sealing and joining the peripheral edge portion 11T of the upper case 11 and the peripheral edge portion 12T of the lower case 12, but the peripheral edge portion 34T of the power supply portion cover 34 is sealed and joined to the peripheral edge portion 11T of the upper case 11, thereby forming a sealing structure of the heater power supply portion 30. Further, the peripheral edge portion 41T of the protective cover 41 is sealingly joined to the peripheral edge portion 12T of the lower case 12, whereby the heater case protective portion 40 is formed in a sealed structure.
The protective cover 41 of the heater case protector 40 serves as a container for storing the heat medium that flows out of the heater case 10 when the heat medium is abnormally high in temperature. The heat medium flowing out of the container is stored, whereby leakage of the heat medium into the vehicle can be suppressed.
In this case, the volume of the protective cover 41 functioning as a container for storing the heat medium (the volume in the sealed space formed by the protective cover 41 and the heater case 10) is preferably smaller than the volume of a temporary storage tank (stock tank) provided in a circulation path of the heat medium including engine cooling of the vehicle.
If the volume of the protective cover 41 is made too large, the heat medium is stored until the heat medium (coolant) in the temporary storage tank becomes empty, and therefore there is a risk that air accumulates in the circulation path of the heat medium. To avoid this risk, the volume of the protective cover 41 is preferably smaller than the difference capacity from the minimum water volume of the temporary storage tank to the water volume of the temporary storage tank in a state where air actually enters the circulation path of the heat medium.
Fig. 5 shows another embodiment of the heating medium heating apparatus 1. In the example shown in fig. 5, the protective cover 41 of the heater case protective part 40 has a discharge hole 42 for discharging the stored heat medium in a specific direction. In this example, the heat medium flowing out of the heater case 10 at the time of an abnormally high temperature of the heat medium is suppressed from overflowing the protective cover 41 and spreading without restriction, and the heat medium is discharged from the discharge hole 42 in a specific direction, whereby the wet damage in the vehicle can be suppressed with a limit. In this case, as a layout of components in the vehicle, it is preferable to eliminate components that have a problem of contact with the heat medium in the water discharge direction of the heat medium.
As described above, the heat medium heating device 1 according to the embodiment of the present invention has a sealing structure that prevents the heat medium from coming into contact with the power supply system of the heater 20 when the heat medium is abnormally high in temperature, and can suppress or restrict leakage of the heat medium into the vehicle, so that safety can be further improved from the viewpoint of failsafe. In addition, such a heat medium heating device 1 can be used with high safety as a heat source (or an auxiliary heat source) of a vehicle air conditioning device that circulates a heat medium to an air conditioning heat exchanger (heater core) provided in an air flow path leading to the vehicle interior.
In the above-described embodiment, the heater 20 is a pair of the 1 st heating element 21 and the 2 nd heating element 22, and the 1 st accommodation space corresponding to the 1 st heating element 21 and the 2 nd accommodation space corresponding to the 2 nd heating element 22 are provided in the heater accommodation portion, but the number of the heaters 20 is not particularly limited, and may be one or more. Accordingly, the number of the accommodating recesses constituting the heater accommodating portion and the number of the accommodating spaces formed by the accommodating recesses are determined according to the number of the heating elements accommodated in the heater accommodating portion, and the shapes of the heating medium flow passages in the heater case 10 are also formed corresponding to the respective heating media.
In the above-described embodiment, the inflow portion 13 and the outflow portion 14 are provided on one end side of the heater case 10, but the present invention is not limited thereto. The location of inflow unit 13 may be a location where the inflowing heating medium can flow into the outer peripheral surface of heater 20, and the location of outflow unit 14 may be a location where the outflowing heating medium can flow out from the outer peripheral surface of heater 20.
