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 Purpose Built Vehicle (PBV).
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 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. Furthermore, 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 includes 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 portion, and an upper vehicle body which may accommodate an occupant.
The PBV vehicle configured in the instant way is provided 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.
Furthermore, 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 may 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.
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 side frame 120 extends from both end portions of the front frame 110 toward a rear of the vehicle body based on a width direction of the vehicle.
The rear frame 130 is connected to each of the side frames 120 at a rear with respect to the front and rear direction of the vehicle.
Herein, the rear frame 130 may be positioned above the front frame 110 based on a height direction of the vehicle.
The front frame 110, the side frame 120, and the rear frame 130 configured in the instant way may be integrally formed.

Furthermore, in the front frame 110, the side frame 120, and the rear frame 130, a plurality of ribs 150 may be formed to crossed vertically, or horizontally, or obliquely based on a top-bottom direction.
The plurality of ribs 150 are formed around the external periphery of the front frame 110, the side frame 120, and the rear frame 130, reinforcing the overall rigidity of the mounting carrier 100.
Accordingly, the mounting carrier 100 may minimize damage to the thermal management module 200 mounted on the mounting carrier 100 by stably absorbing and dispersing the impact force generated during a front collision of the vehicle.
In the exemplary embodiment of the present disclosure, the thermal management module 200 may be mounted in the receiving space 102.
