Definitions

  • the autonomous cooling integrated vest relates to the field of heat exchange systems, specifically systems to cool an individual. More specifically, the described invention relates to the cooling systems associated with the garments whose purpose is to maintain thermal comfort of the users in high temperature environments and to provide the user with protection against impacts.
  • Certain branches of human activity are usually exercised using clothing that inhibits the exchange of heat between the human body and the environment, also, the natural means of cooling the human body can present unsatisfactory performance under certain specific environmental conditions.
  • MOMO ADC Pro Driver Cooling System features a shirt with a water circuit juxtaposed to the shirt itself, wherein water chilled by an ice box flows;
  • Macna Dry Cooling Vest features a vest in which the inner part is made of a water-retaining material and the outer part is impermeable to water and has holes for the passage of ambient air. The vest is wetted so that the inside is soaked in water, the evaporation of this water promotes the user's cooling;
  • the autonomous cooling vest is intended to:
  • the present invention comprises a vest integrated with a cooling support system.
  • Evaporation of a liquid in contact with a person's skin surface causes a cooling effect. Based on this phenomenon, the present invention disperses a coolant liquid on liquid retaining screens which are kept in contact with the surface of the vest user in parts of the body corresponding to the chest, back, abdomen, arms or legs.
  • the cooling support system includes:
  • the present invention comprises a set of interconnected devices so that the dispersion of liquid over the screens and the ventilation incident on the same screens occurs without the need for user action.
  • each screen is integrated with a multifunctional panel that is attached to the vest in the parts corresponding to the user's chest, back, abdomen, arms or legs, the multifunctional panel being permeable to ambient air and adapted to accommodate in its interstice the components of the cooling support system that act directly on the respective screen.
  • a duct network connects the reservoir to the screens.
  • a device called a calibrated orifice which restricts the flow of liquid through it, is connected to each of the terminal branches of the duct network, so that the flow of liquid in each terminal branch is a function of the pressure of the liquid at the entrance of the calibrated orifice and also a function of the caliber of this calibrated orifice.
  • An air electropump pressurizes the reservoir and a pressure switch, connected to the electropump in order to control its activation, keeps the pressure inside the reservoir stable and, consequently, keeps the pressure stable at the entrance of each calibrated orifice.
  • a device hereinafter called a timer, is connected to a solenoid valve in order to open and close the flow of liquid in the solenoid valve repeatedly according to the opening and closing times adjusted by the user through a selector switch integrated in the timer.
  • the inlet nozzle of the solenoid valve being connected to the liquid outlet nozzle of the reservoir and the valve outlet nozzle connected to the inlet of the duct network.
  • At least one fan installed in the interstice of each multifunctional panel ventilates the liquid retained on the respective screen of the multifunctional panel, and the wearer controls the activation of the fans through an electrical current switch button.
  • the present invention has an advantage over the state of the art by:
  • the vest preferably:
  • the cooling support system that is integrated into the vest preferably consists of: a reservoir, multifunctional panels, a pressure switch, an air electropump, a solenoid valve, a timer, a calibrated orifice for each multifunctional panel, a fan for each multifunctional panel, one electric current supply, three electric current supply circuits, a duct network with a terminal branch for each multifunctional panel, two electric current switches and two compartments.
  • Each multifunctional panel (106, 107, 108, 109, 210, 211, 212 and 213), preferably:
  • the multifunctional panels are attached to the vest, preferably:
  • the pressure tap socket and the outlet nozzle of the air electropump are connected by hose segments with an internal diameter of 1/8 in to a Y-shaped adapter (907) with spike couplings that is connected by another segment (908) from the same hose to the air passage nozzle (204) at the top of the reservoir.
  • the inlet nozzle (910) of the solenoid valve is connected to the outlet nozzle (205) of the reservoir through a hose segment with an internal diameter of 1/8 in.
  • the duct network with a terminal branch for each multifunctional panel preferably:
  • each terminal branch of the duct network must be inserted in the first channel (404) of a multifunctional panel at a maximum depth of 2.0 cm and fixed in this position with adhesive as shown in FIG. 7 .
  • the first electric current supply circuit preferably: connects in series the electrical contacts of the air electropump, the pressure switch, a first electric current switch (802) and the battery.
  • the second electrical current supply circuit preferably: connects in series the electrical contacts of the solenoid valve, timer, first power switch and battery.
  • the third electric current supply circuit preferably:
  • the first compartment shown in FIG. 9 preferably:
  • the second compartment shown in FIG. 8 preferably:
