[0021] Embodiment 1, as Figure 1 As shown, in this embodiment, a physical cooling heat dissipation patch includes a shell 6, a thermal conductive part 1 and a temperature control component. The thermal conductive part 1 includes a liquid pass 1-1. The liquid pass 1-1 is a capsule structure made of silicone material. One side of the liquid pass 1-1 is in contact with the human head or other parts that need to be cooled. The two ends of the liquid pass 1-1 are respectively provided with a tube body 1-2 connected to the inner cavity of the liquid pass 1-1. A temperature conduction medium flows in the thermal conductive part 1. In this embodiment, the temperature conduction medium is pure water. The temperature control component includes a water pump 2, a heat dissipation component 3, a thermoelectric cooling sheet 4 and a controller 5. The water pump 2, the heat dissipation component 3, the thermoelectric cooling sheet 4 and the controller 5 are all arranged in the shell 6. A heat conductive sheet is arranged on the water pump 2, and the heat conductive sheet is in contact with the cold end of the thermoelectric cooling sheet 4. The heat dissipation assembly 3 includes a substrate 3-1, the bottom surface of the substrate 3-1 is provided with a heat-conducting surface that fits the hot end of the thermoelectric cooling sheet 4, and the top surface of the substrate 3-1 is provided with a plurality of vertically and parallelly arranged heat dissipation sheets 3-2. The two tube bodies 1-2 are respectively connected to the water inlet pipe 2-1 and the water outlet pipe 2-2 of the water pump 2. The water pump 2 and the thermoelectric cooling sheet 4 are both electrically connected to the controller 5.

[0022] The working principle of this embodiment is:

[0023] When in use, the user places the inner side of the liquid passer 1-1 against the surface of the human body, and the human body and the liquid passer 1-1 perform heat exchange, and the liquid passer 1-1 performs heat exchange with the pure water inside it. The water pump 2 is controlled by the controller 5 to start working, so that the pure water in the liquid passer 1-1 circulates, and the temperature sensor in the water pump 2 detects the temperature of the pure water flowing through the water pump 2 in real time, and transmits the temperature data to the controller 5. In this embodiment, the temperature set in the controller 5 is a threshold of 24 degrees. When the detected temperature is higher than 24 degrees, the controller 5 controls the thermoelectric cooling sheet 4 to cool, and performs heat exchange with the pure water flowing through the water pump 2 through the heat conducting sheet, thereby playing a role in cooling the pure water in the liquid passer 1-1, and then realizing the cooling effect on the human body. The heat generated by the hot end of the thermoelectric cooling sheet 4 is transferred to the substrate 3-1 and then transferred out through the heat sink 3-2 to achieve cooling.

[0024] Compared with the prior art, this embodiment can maintain the temperature of the thermal conductive component 1 constant through the above technical solution, continuously cool down the human body, and avoid the problem of poor cooling effect caused by the temperature rise of traditional heat dissipation patches after being used for a period of time.

[0025] Embodiment 2, as Figure 2 As shown, based on the first embodiment, this embodiment also includes a fan 3-3, and the fan 3-3 is arranged on the top of a plurality of heat sinks 3-2. The fan 3-3 is electrically connected to the controller 5. In this embodiment, a blowing fan is selected as the fan 3-3.

[0026] The working principle and beneficial effects of the above technical solution are:

[0027] The heat generated by the hot end of the thermoelectric cooling sheet 4 is transferred to the substrate 3-1 and then to the heat sink 3-2. The fan continuously blows air to the heat sink 3-2 to dissipate heat. Compared with natural heat dissipation, the heat dissipation effect is better and the heat dissipation efficiency is higher.

[0028] Embodiment three, as Figure 3 As shown, on the basis of the first embodiment, the present embodiment further includes a fan 3-3 and a second housing 3-4. In the present embodiment, a blower 3-3 is selected as the fan 3-3. The heat sink 3-2 is arranged in the second housing 3-4, and the two side portions corresponding to the second housing 3-4 are opened. The fan 3-3 is arranged at one of the openings to promote the air flow in the second housing 3-4. A plurality of heat sinks 3-2 and the upper and lower ends of the housing form an air duct, and the air duct is connected to the openings at both ends of the second housing 3-4. The fan 3-3 is electrically connected to the controller 5.

[0029] The working principle and beneficial effects of the above technical solution are:

[0030] The heat generated by the hot end of the thermoelectric cooling sheet 4 is transferred to the substrate 3-1 and then to the heat sink 3-2. The blower 3-3 continuously blows air into the shell 2 3-4 to accelerate the air flow and dissipate the heat of the heat sink 3-2. Compared with the heat dissipation method in the second embodiment, the blower 3-3 in this embodiment is sideways, and the shell 2 3-4 is used as an air duct, so the air flow rate is higher, the heat dissipation effect is better, and the heat dissipation efficiency is higher.

[0031] Embodiment 4, as Figure 4 As shown, based on the first embodiment, this embodiment further includes a fan 3-3, which is arranged on the side of a plurality of heat sinks 3-2, and is electrically connected to a controller 5. In this embodiment, a blower fan is selected as the fan 3-3. A plurality of heat sinks 3-2 are connected by a heat pipe 3-5, which is in contact with the hot end of the thermoelectric cooling sheet 4, and the contact surface between the heat pipe 3-5 and the hot end of the thermoelectric cooling sheet 4 is a flat structure. In this embodiment, the heat pipe 3-5 is a copper pipe.

[0032] Embodiment 5, as Figure 5 As shown, based on the first embodiment, in this embodiment, a plastically deformable metal mesh 1-3 is embedded inside the top surface of the liquid passer 1-1.

[0033] The working principle and beneficial effects of this embodiment are as follows:

[0034] When in use, after the liquid passer 1-1 is attached to the human body surface, the top of the liquid passer 1-1 is pressed to make the metal mesh 1-3 plastically deformed so as to be more attached to the human body surface. This arrangement not only expands the contact area between the human body and the liquid passer 1-1, but also improves the connection between the human body and the liquid passer 1-1, playing a certain clamping role.

[0035] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
