CROSS-REFERENCE TO RELATED APPLICATION

This application is the continuation application of U.S. patent application Ser. No. 17/544,348 filed on Dec. 7, 2021, which claims the benefit of priority to Korean Patent Application No. 10-2021-0080011 filed on Jun. 21, 2021 in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a mounting structure of a thermal management module for a vehicle. More particularly, the present disclosure relates to a mounting structure of a thermal management module for a vehicle for stably mounting a thermal management module while minimizing a mounting space in front of a vehicle body in a PBV (Purpose Built Vehicle).

BACKGROUND

Recently, the vehicle industry has introduced a new concept of future mobility visions for realizing a human-centered dynamic future city.

One of these future mobility solutions is a PBV (purpose-built vehicle) for purpose-based mobility.

The PBV is an environment-friendly mobility solution that provides customized services necessary for occupants during the time of moving to the destination on the ground, and it may also perform setting of an optimal path and cluster driving for each situation using electric vehicle-based and artificial intelligence.

In other words, the PBV vehicle is a means of transportation and a fixed facility in which case-related technologies are concentrated, and has an autonomous driving function so that a separate driver's seat is unnecessary. In addition, the indoor space has substantial expandability.

This PBV vehicle may be changed not only to a role of a shuttle that moves a plurality of people, but also to recreational spaces such as restaurants, cafes, hotels, and movie theaters, and socially essential facilities such as hospitals and pharmacies.

Here, the PBV vehicle is moved using an electric motor for power, and consists of a skateboard-type rolling chassis (also called an underbody or a skateboard in the industry) in which a battery is widely spread on the lower part, and an upper vehicle body that may accommodate an occupant.

The PBV vehicle configured in this way is equipped with an air conditioner for controlling the indoor temperature of the upper vehicle body, and a thermal management module that supplies a coolant or a refrigerant to the air conditioner, however, there is a problem that it is difficult to dispose each constituent element of the thermal management module in a narrow mounting space, and the layout of pipes through which the coolant or the refrigerant flows is complicated.

In addition, due to the limitation of the mounting space of the rolling chassis, the constituent elements of the thermal management module or the constituent elements of the air conditioner must be mounted on the upper vehicle body, and there is also a problem in that the internal space of the upper vehicle body is reduced.

In order to solve these problems, there is a need to develop a technology for mounting the thermal management module and the air conditioner on the rolling chassis.

The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure, and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

SUMMARY

Therefore, the present disclosure is intended to solve the problem as described above, and the problem to be solved by the present disclosure is to provide a mounting structure of a thermal management module for a vehicle stably mounting the thermal management module while minimizing the mounting space in front of the vehicle body in the PBV (Purpose Built Vehicle).

The coolant circulator 110 and the refrigerant circulator 120 configured in this way may be mounted on the first mounting bracket 50 or the second mounting bracket 60, respectively, without the first mounting bracket 50 and the second mounting bracket 60 being coupled together.

In addition, since the coolant circulator 110 and the refrigerant circulator 120 are disposed to the adjacent positions, the coolant may be smoothly supplied to the constituent element that heat-exchanges the refrigerant in a water-cooled manner using the coolant in the refrigerant circulator 120.

On the other hand, in the present embodiment, it is described that the coolant circulator 110 is mounted to the first mounting bracket 50 and the refrigerant circulator 120 is mounted to the second mounting bracket 60 as an exemplary embodiment, however it is not limited to this, and it may be applied by changing a position of a non-illustrated air conditioner or the mounting bracket used according to a design condition.
