Sumitomo Riko Exhibits at the Automotive
Engineering Exposition 2024
- Exhibiting of EVs related product “Battery Cooling Plate” for the
first timeSumitomo Riko Co., Ltd (Headquarters: Nakamura-ku, Nagoya; President & CEO:Kazushi Shimizu) will exhibit at the Automotive Engineering Exposition 2024, which
will be held at Pacifico Yokohama (Nishi-ku, Yokohama) from May 22 (Wed.) to 24(Fri.) and at Aichi Sky Expo (Tokoname, Aichi) from July 17 (Wed.) to 19 (Fri.).

We will be exhibiting jointly with Sumitomo Electric Industries, Ltd. (Chuo-ku, Osaka)
and Sumitomo Wiring Systems, Ltd. (Yokkaichi, Mie). Our booth will exhibit
technologies and products centered on three themes: carbon neutrality, EVs, andautomated driving, as initiatives to support a safe, comfortable, and green future.

Dates【STAGE 1】Wednesday, May 22 - Wednesday, June 5【STAGE 2】Wednesday, July 10 - Wednesday, July 31＜Exhibits＞＞＞Battery Cooling Plate: Cool Fit Plate【First time on Exhibit（Patent pending）】
This is a battery cooling product to efficiently cool thebottom of the battery (the upper side of the flow path)and furthermore to equalize the temperature of thebattery. It features protrusions in the parallel flow paths,
which generate vortex and agitate the fluid boundary
layer, resulting in efficient cooling performance.
Moreover, by placing the protrusions in the optimal
locations, the cooling efficiency can be improved at any
point, thereby reducing the temperature difference
between different parts of the battery, which contributes
to extending battery life.

＞＞Driver Monitoring System (Seat Integrated Type)
This is a product in which our proprietary sensor isprocessed into a cushion shape and integrated with theseat. By acquiring data on pressure changes on the seatsurface measured by the sensor, biometric information(vital data based on heartbeat component, respirationcomponent, etc.) can be estimated. Based on themeasurement data from the seat-type sensing device,
the system can be linked to services such as detecting
driver falling asleep or signs of fatigue, responding toabnormal situations of passengers, operation support bymanagers, and labor management.
＞＞Thin Film High Thermal Insulation Material:
Finesulight
We have applied polymer material technology to createa coating of high-insulation filler (silica aerogel) with
nano-sized pores so fine that air cannot move. By
coating base materials such as non-woven fabrics andmolded resins with this product, higher thermal
insulation properties can be achieved than in the still air.
This product, which improves the heating and cooling
effect of the cabin space in EVs, contributes to extending
the cruising range by reducing electric power costs.
＞＞Heat Dissipation and Soundproofing Material:
MIF（Magnetic Induction Foaming）
This is a soundproofing urethane that combines “heatdissipation” and “soundproofing”. Urethane containing
heat-conductive particles is foamed and molded in amagnetic field, which connects the particles and forms aheat pathway. The heat dissipation performance is 10 to
50 times higher than that of ordinary urethane foam(according to our research). It contributes to noise andheat reduction for in-vehicle electrical equipment suchas motors and eAxle.

＞＞Automotive Window Film
By attaching this product to automobile glass, it
provides the effects of heat shielding and UV blocking.
By uniformly dispersing transparent conductive
material, the film ensures both visibility while driving
and a heat shielding function that absorbs heat(near-infrared rays) from the sun, thereby
contributing to improved cabin comfort and reduced
air-conditioning load. The product has been used inapproximately 160,000 vehicles 1 in Southeast Asia
(Malaysia).
＞＞Light Transmitting Interior Components
This is a product that utilizes our originally developed
light-transmissive surface skin to create an interiorspace. The product provides a high-quality interior
under normal conditions, and when in use, the surface
skin is linked to the backlight illumination, allowing theuser to experience advanced illumination. It can also be
used as a sensing device and as an HMI device withswitches that are visible only when in use.
