Definitions
- the present disclosure relates to a vehicular thermal management system, and more particularly, to a vehicular thermal management system configured to perform thermal management of a passenger space, electrical components and a high-voltage battery of a vehicle including a first vehicle body having the passenger space therein and a second vehicle body combined with the first vehicle body so as to define the entirety of the vehicle.
- a conventional internal-combustion engine vehicle does not need additional energy for warming the indoor space thereof because it is possible to warm the indoor space in the vehicle using waste heat generated by the engine.
- the indoor space must be warmed using additional energy, thus increasing fuel consumption. This reduces the distance that the electrical vehicle is capable of traveling, leading to more frequent charging of the battery, which is problematic.

Abstract
Description
- This application claims the benefit of priority to Korean Patent Application No. 10-2020-0028266, filed on Mar. 6, 2020 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
- The present disclosure relates to a vehicular thermal management system, and more particularly, to a vehicular thermal management system configured to perform thermal management of a passenger space, electrical components and a high-voltage battery of a vehicle including a first vehicle body having the passenger space therein and a second vehicle body combined with the first vehicle body so as to define the entirety of the vehicle.
- In recent years, the trend is toward the popularization of electrical vehicles or the like as eco-friendly vehicles on account of environmental issues affecting internal-combustion vehicles. A conventional internal-combustion engine vehicle does not need additional energy for warming the indoor space thereof because it is possible to warm the indoor space in the vehicle using waste heat generated by the engine. However, because an electrical vehicle or the like is not provided with an engine serving as heat source, the indoor space must be warmed using additional energy, thus increasing fuel consumption. This reduces the distance that the electrical vehicle is capable of traveling, leading to more frequent charging of the battery, which is problematic.
- With the motorization of vehicles, the need for thermal management of electrical components such as a high-voltage battery and a motor as well as the indoor space of the vehicle are newly required. Specifically, in an electrical vehicle, because the indoor space, the battery and the electrical components have different air-conditioning needs, there is need for a technology capable of independently responding to the different needs and of efficiently reconciling the different needs so as to achieve maximal energy conservation. Accordingly, concepts for integrated vehicular thermal management, which is capable of increasing heating efficiency by performing independent thermal management for individual components of a vehicle and by integrally performing the overall thermal management, have been proposed.
- In these days, a concept by which a vehicle is constituted by a first vehicle body, which can be applied in common to many kinds of vehicles, and a second vehicle body, which is combined with the first vehicle body so as to constitute the entire body of the vehicle, have been proposed. Specifically, in order to constitute the complete body of an electrical vehicle, a first vehicle body, which is provided with electrical components, a battery and the like, which are applied in common to electrical vehicles, and a second vehicle body, which defines a passenger space therein and is combined with the first vehicle body so as to constitute the entirety of the body of the vehicle, are combined with each other.
- Vehicular thermal management systems that have been proposed to date are associated only with a vehicle in which an indoor space, electrical components and a battery are included in a single vehicle body. Therefore, there is a need to develop technology for a vehicular thermal management system that is applicable to the above-mentioned kind of vehicle, which is composed of a first vehicle body and a second vehicle body.

FIG. 37 is a schematic view illustrating a vehicular thermal management system according to a fourth exemplary embodiment of the present disclosure. Referring toFIG. 37 , the vehicular thermal management system according to the fourth embodiment of the present disclosure may include an indoor-air-conditioner 100 and a component-air-conditioner 200. - The vehicular thermal management system according to the fourth exemplary embodiment of the present disclosure may further include a
second condenser 191 to which the refrigerant output from thecompressor 110 is input and asecond valve 192 disposed between thesecond condenser 191 and thefirst condenser 120, unlike the indoor-air-conditioner 100 of the vehicular thermal management system according to the third exemplary embodiment. - Since the remaining construction and features of the indoor-air-
conditioner 100 are substantially the same as those of the indoor-air-conditioner 100 of the vehicular thermal management system according to the third exemplary embodiment, which has been described above, a detailed description thereof is omitted. - In addition, since the construction and the features of the component-air-

FIGS. 38 to 48 andFIG. 49 , the operations and the flow of the refrigerant and the coolant in individual modes of the vehicular thermal management system according to the fourth exemplary embodiment of the present disclosure will now be described. - When there is a need to cool both the passenger space and the
electrical component 210 while traveling at high temperature, as in the summer months, it is possible to supply the cool air to the passenger space from theblower 150 through thefirst flow path 195 and thus to cool the passenger space by activating thecompressor 110, opening thesecond valve 192, expanding the refrigerant output from thefirst condenser 120 through thefirst valve 180, closing thesecond flow path 170 through thefirst door drive 194 and separating thesecond flow path 170 from thethird flow path 195 through thesecond door drive 197, and it is possible to cool the coolant in theelectrical component line 220 through thefirst radiator 275 and thus to cool theelectrical component 210 by circulating the coolant in theelectrical component line 220 through activation of thefirst pump 280 under the control of thecontroller 300, as illustrated inFIG. 38 . - Here, the reason why the
