The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, and therefore only serve as examples, and cannot limit the protection scope of the utility model.

[0025] Please refer to Figure 1 and 4 The utility model provides a kind of heat exchange system suitable for cooling cap, including receiving chamber 2, heat exchange chamber 3, tower radiator 4, conveying pump 5, temperature detection module (not shown in drawing) and control unit.The receiving chamber 2 is used to accommodate heat exchange liquid.The heat exchange chamber 3 side is equipped with the first exchange port 31 for heat exchange liquid input, and the second exchange port 32 for heat exchange liquid output, and two exchange ports are communicated with receiving chamber 2 or cooling cap by corresponding conveying pipeline respectively.The structure of general single-tower tower radiator 4 can refer to Chinese utility model patent with publication No.CN217689982U, it includes base, the heat dissipation fin group being arranged at the top of the base, and fan assembly being arranged at one side of the heat dissipation fin group;And the application is eight-tower four-core air-cooled radiator to realize refrigeration cooling.The base of the tower radiator 4 is attached to one side of the heat exchange chamber 3.The input end of the conveying pump 5 is communicated with the receiving chamber 2, and the output end is communicated with the cooling cap to be used for directly pumping and discharging the heat exchange liquid in the receiving chamber 2 into the cooling cap.Obviously, the output end of the conveying pump 5 can also be communicated with the heat exchange chamber 3, to be used for pumping and discharging the heat exchange liquid in the receiving chamber 2 into the heat exchange chamber 3 and then inputting into the cooling cap.The detection end of the temperature detection module is embedded in the heat exchange chamber 3.The control unit is electrically connected with tower radiator 4, conveying pump 5 and temperature detection module respectively, to realize refrigeration, cold sending, temperature control and other operations based on the instruction issued by medical staff.In general, control unit includes the key / touch screen being arranged at the side of cabinet 1 and the processor being built-in in cabinet. EMBODIMENT

[0026] The embodiment aims to provide a heat exchange structure designed based on the heat exchange principle of the application. Specifically, a coil is arranged in the heat exchange chamber 3, which is generally provided in a U shape, please refer to Figure 4 The two ends of the coil are in communication with the first exchange port 31 and the second exchange port 32, respectively. In the embodiment, the heat exchange chamber 3 is designed in a blade structure to obtain a larger heat dissipation surface area, and the two surfaces of the blade can be arranged with tower heat sinks 4, and the two tower heat sinks 4 are connected in series through connecting rods to tightly hold the heat exchange chamber 3 in a blade structure. Generally, in a constant temperature environment such as a hospital using an air conditioning system, only relying on the tower heat sink 4 is sufficient to meet the required refrigeration requirements. However, the heat exchange performance and rate in high temperature environment with abnormal cooling still need to be considered, therefore, the thermoelectric refrigeration sheet is further provided between the tower heat sink 4 and the heat exchange chamber 3, which utilizes the Peltier effect of semiconductor materials, when electricity passes through an electric couple formed by connecting two different semiconductor materials in series, heat can be absorbed and released at the two ends of the electric couple, respectively, thereby achieving the purpose of refrigeration. The thermoelectric refrigeration sheet is clamped between the base and the heat exchange chamber 3, so that the cold end of the thermoelectric refrigeration sheet is tightly attached to the heat exchange chamber 3, and the hot end is tightly attached to the base of the heat sink, thereby realizing rapid heat dissipation through the heat pipe, heat dissipation fins and fan.

[0027] As a further improvement of the above scheme, the heat exchange system comprises a box body 1, and the box body 1 is provided with an anti-collision framework 8 and a mounting plate 9. Specifically, please refer to Figure 2 The anti-collision framework 8 is fixedly connected with the inner wall of the box body 1, and the inside of the anti-collision framework 8 is used to accommodate the mounting plate 9 and the mounting components thereon; the mounting plate 9 is used to fix the above-mentioned accommodation chamber 2, heat exchange chamber 3, tower heat sink 4 and delivery pump 5. Among them, please refer to Figure 1 and 5 The box body 1 can be vertical or horizontal; the vertical box body 1 is provided with universal wheels at the bottom to facilitate movement, while the horizontal box body 1 can be placed on a trolley for transportation / plug-in use when needed. By providing the anti-collision framework 8, on the one hand, the overall structure of the box body 1 is enhanced, and on the other hand, the installation difficulty of the whole heat exchange system is reduced - that is, the accommodation chamber 2, heat exchange chamber 3, tower heat sink 4 and delivery pump 5 can be first fixed in the anti-collision framework 8 outside the box through the mounting plate 9, and then the framework is placed in the box body 1 and connected with the pipeline and line.

[0028] Since the anti-collision framework 8 only enhances the structural strength of the box 1, the energy-absorbing and shock-absorbing effect is poor. In order to further reduce the damage to the internal components caused by frequent daily use / transportation due to bumps and impacts, an energy-absorbing and shock-absorbing structure can also be provided between the anti-collision framework 8 and the mounting plate 9. Specifically, the mounting plate 9 and the anti-collision framework 8 are connected by a fixed rod 81, and a pair of shock-absorbing members 82 are sleeved on the outer periphery of the fixed rod 81, and a pair of shock-absorbing members 82 are arranged on both sides of the mounting plate 9. One embodiment, please refer to Figure 3 , the anti-collision framework 8 is composed of a plurality of rod bodies combined into a rectangular frame structure, and the mounting plate 9 and the corresponding rod body are connected by a fixed rod 81; the fixed rod 81 includes a screw rod and a limiting plate arranged at one end of the screw rod, and the screw rod is threadedly connected with the corresponding rod body of the anti-collision framework 8 after penetrating through the mounting plate 9. A pair of shock-absorbing members 82 are sleeved on the outer periphery of the screw rod. Among them, the shock-absorbing member 82 can be a spring, an elastic rubber sleeve, or a combination of a spring and a rubber sleeve. Embodiment

The corresponding delivery pipeline includes a first delivery pipe 71, a second delivery pipe 72, and a third delivery pipe 73; wherein one end of the first delivery pipe 71 is in communication with the storage chamber 2, and the other end penetrates through the box 1 and is used to communicate with the first interface of the cooling cap; one end of the second delivery pipe 72 is in communication with the first exchange port 31 of the heat exchange chamber 3, and the other end penetrates through the box 1 and is used to communicate with the second interface of the cooling cap; the third delivery pipe 73 is in communication with the storage chamber 2 and the second exchange port 32 of the heat exchange chamber 3 at both ends. Then the setting position of the delivery pump 5 has two options: ① the delivery pump 5 is arranged between the first delivery pipe 71 and the storage chamber 2, so as to directly pump the heat exchange liquid in the storage chamber 2 into the cooling cap, and then backflow to the heat exchange chamber 3 through the second delivery pipe 72, and then backflow to the storage chamber 2 through the third delivery pipe 73 after being cooled by the heat exchange chamber 3, so as to keep the heat exchange liquid stored in the storage chamber 2 at a temperature environment suitable for the normal operation of the cooling cap, and thus the cooling of the cooling cap is realized through the circulation; ② the delivery pump 5 is arranged between the third delivery pipe 73 and the storage chamber 2, so as to pump the heat exchange liquid in the storage chamber 2 to the heat exchange chamber 3 for cooling, and then input into the cooling cap through the second delivery pipe 72, and then backflow to the storage chamber 2 through the first delivery pipe 71, so as to realize the cooling of the cooling cap through the circulation.
