Fig. 16 and 17 are partially exploded views and schematic views of an eighth embodiment of the present invention, and fig. 18 is a schematic view of a ninth embodiment of the present invention; comparing the heat energy transferring device 8 of the eighth embodiment with fig. 4, the difference is that the two sides of the first through hole 206 disposed at the center of the lower plate 20' do not have the position-limiting groove 207 and the position-guiding member 22; compared with fig. 4, the thermal energy transfer device 9 of the ninth embodiment does not have the support member 16, the scraper 24, the pressing plate 25, the bearing plate 26, the upper plate 27, the lower plate 28, the limiting groove 207 and the guiding member 22. This is so designed that the connector 32 ' of the gas cartridge 3 ' without the retaining ring 33 and the rib 34 can also be applied to the device, i.e. the combination of the gas cartridge 3 ' and the quick connector 21 is no longer secured by the rib 34 and the retaining groove 207, but a control part 7 is designed on the exterior of the application device 1, and then the thermal energy transfer devices 8, 9 are placed thereunder, for example: it can be designed into a gap with a hollow part 71 to ensure that the gas storage bottle 3' can smoothly enter and exit, and the side edge is provided with a retaining ring 72; a cover 73 is connected to the upper side of the hollow portion 71, and a fastening portion 74 is provided on the side of the cover 73.
