q-JUD Thermal Comfort Dummy

The heating and control system of q-JUD thermal comfort dummy can be divided into temperature sensing control system, heating control system and water leakage detection and alarm system through modular design.

The heating and control system is responsible for the important task of simulating human body heat dissipation and water leakage detection for the dummy test system. Generally speaking, the layout of the system is mainly divided into two categories, built-in and external. The advantage of the built-in type is that it has a strong overall sense and is easy to move. The disadvantage is the heat generated by its own electrical system, but this part of the heat is not the heating output on the heating plate, which will affect the accuracy of the dummy’s external thermal power output calculation.

All components are designed with forward R&D for TDP heat dissipation power. The power of the components used is at the milliwatt level, and the heat generation rate is very slight; secondly, before the circuit board of the components is sealed, materials such as composite carbon fiber will be used for the circuit board or the circuit board or the circuit board. The main heat-generating components are thermally strengthened. Since the thermal conductivity of thermally conductive carbon fiber can reach 700W/m.K, which is more than twice that of pure copper, carbon fiber is used to dissipate heat inside the chamber, and the heat dissipation capacity is completely guaranteed. The thermally conductive carbon fiber is connected to the inside of the functional polymer shell, which can also play the role of toughening and strengthening of the resin filling material. Since the heat dissipation capacity of the functional polymer shell itself is slightly better than that of the human body, the heat generation of the low-power internal components in the inner layer will not cause accumulation, and the stability of the components inside the dummy can be effectively guaranteed.

Joint design of the q-JUD thermal comfort dummy: Preliminary consideration is to use the same material as the dummy shell to realize the joints of the dummy by machining, which can effectively avoid the generation of local stress caused by changes in ambient temperature. Route the cables through the three-way wire holes at the joints to ensure that the movement at the joints does not interfere with the internal cables. Through the elimination of joint movement interference points, it is ensured that the movement angle of large joints is greater than 90 degrees.
