Temperature regulating and controlling system and method

Abstract

The invention relates to a temperature regulating and controlling system and method. The system comprises a heat exchange device, a temperature sensor, a controller and a cooling device. The heat exchange device is used for refrigerating or heating. The temperature sensor is used for detecting a temperature signal of an object to be subjected to heat exchange. The controller is connected with the temperature sensor and the heat exchange device and used for receiving a temperature signal transmitted by the temperature sensor and controlling the heat exchange device to perform refrigerating or heating after performing judgment. The cooling device is fixedly connected with the heat exchange device and used for receiving heat generated in the refrigerating process of the heat exchange device. According to the temperature regulating and controlling system and method, by arranging the temperature sensor and the heat exchange device, the heat exchange device can be controlled and driven by the controller to perform refrigerating or heating according to the temperature signal of the object to be subjected to heat exchange; by arranging the cooling device, heat generated when the heat exchange device performs refrigeration can be dissipated, and it is avoided that the heat exchange device is damaged because of overheating.

Description

technical field [0001] The invention relates to a temperature control system and method, in particular to a temperature control system and method for returning the brain, which has been heated up due to high-intensity mental work, to a normal temperature following the self-refrigeration mechanism of the human brain. Background technique [0002] Generally speaking, the brain tissue of adolescents (over 16 years old) and adults weighs about 1.35kg, accounting for 2% of the body weight, but the blood supply it requires accounts for 15% of the cardiovascular output, and the oxygen required accounts for 15% of the body's resting state. 20%-30% of total oxygen consumption. Due to the vigorous metabolism of brain cells, a large amount of heat is bound to be generated in the process of human brain activity, and the brain has also become a high heat-producing area of ​​the human body. When the human body is resting, the heat production per unit mass of the whole brain is 6 times hig...

Problems solved by technology

[0004] In some extreme situations of the human body, such as after high-intensity cognitive tasks, the temperature regulation mechanism of the brain itself will be abnormal, because the contraction and relaxation of blood vessels is regulated by the autonomic nervous system, and the cerebral cortex nerves directly control and regulate In the autonomic nervous system, long-term use of the brain will lead to hyperactivity in some areas of the cerebral cortex, and unified and coordinated dysfunction. The sympathetic nerves are excited and the parasympathetic nerves are inhibited, resulting in vascular tension and spasm in the brain, slow blood stasis, arterial and venous blood reverse flow exchange and two-way Impaired blood flow mechanisms, resulting in abnormally elevated temperatures in the brain

[0005] Elevated intracranial temperature is not only a symbol of brain fatigue, but also damages brain cells, affects substance metabolism, and causes a variety of neurotransmitters ( Abnormal distribution of acetylcholine, norepinephrine, serotonin, glutamic acid, etc.), which in turn affects the individual's information processing ability, such as decreased judgment, poor planning, weakened executive ability, rigid thinking, difficulties in maintaining attention and motivation, etc.

[0006] We often yawn after lack of sleep or long-term mental work. In fact, we stretch the facial muscles to increase the blood flow of the blood vessels in the head and face and promote the exchange process to cool the brain. "It is impossible to restore the temperature regulation mechanism of the brain

[0007] Children and adolescents, mental workers, and those who have been on night shifts for a long time have higher brain activity and slightly higher intracranial temperatures. Powerful mental work, and the phenomenon of staying up late to prepare for exams often occurs, the above-mentioned autonomic disorders are most likely to occur, and the intracranial temperature will also increase accordingly. The "high fever" state of the brain will not only affect cognitive ability , leading to a decline in learning efficiency and damage to brain tissue, resulting in long-term adverse effects

Such people usually buy some brain-building nutrients or coffee and cooling oil products, but they only supplement the nutrients needed for brain work or stimulate brain tissue for a short time, and do not restore the brain to normal working temperature and Work motivation, long-term use will also affect the secretion of human hormones and the growth and development of adolescents
