The invention provides a beveling combustion hole rotation aiding low-pollution backflow combustion chamber which is of a single annular cavity structure. The beveling combustion hole rotation aiding low-pollution backflow combustion chamber is composed of combustion chamber boxes, a flame tube inner wall, a flame tube outer wall, a big bended tube, a small bended tube and combustion chamber heads, air entering from an inlet enters the combustion chamber through a diffuser, airflow is divided into three portions, the three portions of the airflow respectively enter the flame tube, the first portion of the airflow enters from the combustion chamber heads via swirl cups and head cooling holes, the second portion of the airflow enters the flame tube from main combustion holes, and the third portion of the airflow is used for cooling the flame tube wall and enters the flame tube from film holes and beveling holes formed in the inner wall of the flame tube, the outer wall of the flame tube, the wall of big bended tube and the wall of the small bended tube, and the airflow in the flame tube is discharged from the combustion chamber after combusting, being mixed and turning by 180 degrees. A swirl cup air atomizing nozzle is applied to each combustion chamber head, and a diffusive combustion organization mode is applied. Each inner ring main combustion hole of the flame tube and the flame tube wall surface form an angle with certain degrees in the circumferential direction, and each outer ring main combustion hole of the flame tube and the flame tube wall surface form an angle with certain degrees in the circumferential direction, and airflow of each inner ring main combustion hole and each outer ring main combustion hole and airflow of each upper wall main combustion hole, corresponding to one head swirl cup, of the flame tube and each lower wall main combustion hole, corresponding to one head swirl cup, of the flame tube form tangential airflow. The beveling combustion hole rotation aiding low-pollution backflow combustion chamber enables spray combustion to be more uniform, and can reduce pollutant discharge.

A cooling system for inducing diving reflex and central nervous system protective hypothermia has a cooler, a refrigerant dispenser, a cooling assembly, a controller and an infusing unit. The refrigerant dispenser connects the cooler. The cooling assembly connects the refrigerant dispenser and communicates with the cooler and has a head cooling set. The controller coordinates the refrigerant dispenser and the infusing unit according to the detection of the physical signal including naso-pharyngeal temperature, and cerebral oximetry signal. The infusing unit connects to the controller and has a catheter. When in use, the cooled liquid is pumped into (1) head cooling set covering the face of the patient to induce diving reflex, (2) the infusing unit having an esophago-gastric tube to lower the temperature inside the stomach. Therefore, an effective, precise diving reflex and central nervous system protective hypothermia can be achieved by this invention.

Systems and methods for providing an article associated with headgear that keeps the wearer's head cool and/or cushioned from the interior harness of the headgear. The article is a system, liner or pad that is inserted into the headgear or coupled to the headgear harness for cooling and/or comfort, and includes a liquid-absorbing material contained within non-impervious pocket partitions. One or more ventilation portions and/or devices may also be included to allow for the free flow of air, breathing of the wearer's scalp and to facilitate the natural evaporation of perspiration. In some implementations, the article may be used in a variety of different headgear. As the pocket partitions swell due to absorption of a liquid by the material, the pockets function as gel-like cushions or pads that protect the wearer's scalp. The article is held in place with small straps, Velcro® tabs, or other retention devices.
