[0037] The current market cooling air-conditioning clothes, usually for a single refrigeration mode, that is, air-cooled or liquid-cooled refrigeration mode, so its cooling effect on the human body is very limited. Therefore, in order to enhance the cooling effect of the existing cooling wear products, the technical scheme puts forward a contact type refrigeration pad structure, which can be connected to the air-cooled system (not shown in the figure) and the liquid-cooled system (not shown in the figure) at the same time, and uses liquid cooling and air cooling to achieve the purpose of cooling together, which is more conducive to meeting the user's experience. In addition, since the design of the wear product in the present scheme is in the mode of refrigeration pad, on the one hand, it can realize independent wearing, and on the other hand, it can be flexibly matched with products such as backpacks, car seat cushions, etc., so as to be applied to more scenes, and more conducive to improving the applicability of the refrigeration pad.

[0038] Specifically, as shown in Figures 1-6 , the contact type refrigeration pad structure of the present scheme uses the adjusting wind generated by the air-cooled system (which can be natural wind or refrigeration wind without processing) and the liquid medium generated by the liquid-cooled system (which can be liquid without processing or refrigeration liquid), and makes the liquid medium and the adjusting wind act on the contact type refrigeration pad structure, uses the cold fluid formed by the liquid medium and the air flow formed by the adjusting wind to take away the heat of the human body, so that the wearer can feel the flow of the adjusting wind under the premise of directly contacting the contact type refrigeration pad structure storing the liquid medium, thereby further enhancing the cool feeling of the wearer in the body sense, making the cooling experience of the wearer more intense, and more conducive to meeting the user's experience.

[0039] In one embodiment, the adjusting wind outlet 212 of the non-contact cooling system 2 and the adjusting wind inlet (not shown in the figure) of the contact type refrigeration pad structure can be detachably connected through a hollow elastic band, so that the wearing of the contact type refrigeration pad structure of the present scheme is more convenient.

[0040] It should be noted that the inner side of the contact type refrigeration pad structure in the present scheme refers to the side of the side that directly contacts the body surface of the wearer. Preferably, the adjusting wind inlet of the present scheme can be arranged at the edge of the contact type refrigeration pad structure.

[0041] In order to make the wearer feel the enhanced cooling effect brought by the two cooling methods at the same time, the structure of the contact type refrigeration pad structure is also optimized in the present scheme, especially the liquid-cooled gas outlet layer 111 of the contact type refrigeration pad structure is provided with cooling air holes 1111 and liquid storage cavities 1112 at the same time, as shown in Figure 2 、 3 , and the cooling air holes 1111 are distributed around the liquid storage cavities 1112, so that the cooling effect of each position on the inner side of the contact type refrigeration pad structure is more uniform, thereby achieving the best cooling experience.
