[0026] See also Figure 1-Figure 6The present invention provides the following technical solution: a wall-type heat exchanger utilizing air energy, comprising a machine room frame 1, the right side of the machine room frame 1 being connected to the machine room outer wall 19, an air inlet 2 being installed at the lower right side of the machine room outer wall 19, an exhaust fan 7 being installed at the upper right side of the machine room outer wall 19, a machine room interior decorative wall 4 being installed inside the right side of the machine room frame 1, a heat exchange corrugated plate 5 being installed between the machine room interior decorative wall 4 and the machine room outer wall 19, a heat exchange outer cavity 3 being arranged between the heat exchange corrugated plate 5 and the machine room outer wall 19, a heat exchange inner cavity 6 being arranged between the heat exchange corrugated plate 5 and the machine room interior decorative wall 4; a return air inlet 17 being installed above the machine room interior decorative wall 4, a blower 8 being installed below the machine room interior decorative wall 4, and a machine room interior decorative wall 4 being provided with a heat exchanger. A sealed anti-static floor 9 and a perforated anti-static floor 13 are installed at the lower part of the room frame 1, an overhead space 10 is set between the sealed anti-static floor 9 and the perforated anti-static floor 13 and the room frame 1, a microporous ceiling 14 is installed above the room frame 1, a ceiling space 16 is set between the microporous ceiling 14 and the room frame 1, a hot channel 15 is set between the microporous ceiling 14 and the sealed anti-static floor 9 and the perforated anti-static floor 13, and temperature sensors 18 are installed in the overhead space 10 and on the outer side of the room outer wall 19; a cabinet 11 is set above the sealed anti-static floor 9 and the perforated anti-static floor 13, and a cold channel 12 is set between the cabinets 11;

[0027] Furthermore, the heat exchange outer cavity 3 and the heat exchange inner cavity 6 are separated by a heat exchange corrugated plate 5. The heat exchange corrugated plate 5 is made of materials with low thermal resistance such as copper and aluminum, and the corrugated plate structure is used to increase the surface area of ​​heat conduction; the position of the cold channel 12 of the computer room corresponds to the position of the perforated antistatic floor 13, so that the air in the computer room can smoothly enter the cold channel 12 of the computer room along the perforated antistatic floor 13 to assist in heat dissipation of the cabinet 11;

[0028] An adjustment frame assembly is provided outside the cabinet 11;

[0029] Further, the adjustment frame assembly includes a mounting seat 22 sleeved on the lower end of the cabinet 11, a connecting plate 24 is installed at one end of the mounting seat 22 at the left position, a fixing plate 23 is installed at one end of the mounting seat 22 at the right position, the fixing plate 23 and the mounting seat 22 are fixed by bolts, a hydraulic rod 25 is installed on the outer side of the mounting seat 22, the output end of the hydraulic rod 25 is connected to the mounting frame 20, and a moving wheel 21 is installed on the lower side of the mounting frame 20;

[0030] Furthermore, the connecting plate 24 is slidably connected to the fixing plate 23, and the lowest point of the fixing plate 23 is flush with the lowest point of the connecting plate 24, so that the size of the mounting seat 22 can be adjusted to adapt to the use of computer rooms of different sizes; the moving wheels 21 are symmetrically distributed at the four corners of the mounting seat 22, and the lowest point of the initial position of the moving wheels 21 is higher than the lowest point of the mounting seat 22, so that the mounting seat 22 contacts the floor, ensuring the stability of the module of the cabinet 11, and adjusting the moving wheels 21 to support the mounting seat 22 is convenient for moving the module of the cabinet 11;

[0031] Specifically, the wall-mounted heat exchanger utilizing air energy is used in an information room having at least one side against the building outer wall, and the outdoor air temperature is measured by a temperature sensor 18 arranged outdoors. When the outdoor air temperature is lower than the required temperature of the cold channel 12 of the room, the exhaust fan 7 on the room outer wall 19 is started, and the outdoor air enters the heat exchange outer cavity 3 through the air inlet 2 with a filter (reducing the pollution of the outdoor air to the heat exchange corrugated plate 5) on the room outer wall 19 due to the negative pressure, and is discharged through the exhaust fan 7, thereby converting the energy of the outdoor cold air into heat. The heat is conducted to the heat exchange corrugated plate 5, and then to the inner cavity air through the corrugated plate. The exhaust fan 7 is arranged above the outer wall 19 of the machine room, and the air inlet 2 is arranged below the outer wall 19 of the machine room. The mechanism of hot air rising and cold air falling is followed (the air temperature of the heat exchange outer cavity 3 rises as the temperature rises after the heat exchange). At the same time, the air supply fan 8 on the decorative wall 4 in the machine room is started to send the air in the heat exchange inner cavity 6 into the cold channel 12 of the machine room through the perforated anti-static floor 13, and then be exhausted to the hot channel 15 of the machine room through the fan of the cabinet 11 itself (at this time The information equipment is cooled, and the air temperature of the cooling information equipment becomes higher). The air in the hot channel 15 of the computer room enters the ceiling space 16 through the microporous ceiling 14 of the computer room, and enters the heat exchange cavity 6 through the return air port 17 due to the negative pressure, forming a circulation of indoor air, and obtains the energy of outdoor air through the heat exchange of the heat exchange corrugated plate 5. The return air port 17 is arranged at the top, and the supply fan 8 is arranged at the bottom, following the mechanism of hot air rising and cold air falling (the air temperature of the heat exchange cavity 6 decreases as the temperature decreases after the heat exchange). The exhaust fan 7 adopts speed regulation operation, and the supply air temperature is measured by the temperature sensor 18 arranged at the air supply port. The speed of the exhaust fan 7 is controlled by proportional integral operation, and the heat exchange amount is controlled by adjusting the speed of the exhaust fan 7 to maintain a constant supply air temperature. The heat exchange corrugated plate 5 physically isolates the heat exchange outer cavity 3 and the heat exchange inner cavity 6. There is no cross phenomenon between the outdoor air and the indoor air during the heat exchange process. Heat exchange is only carried out through the air temperature difference between the two sides of the medium (heat exchange corrugated plate 5). When the outdoor air temperature is higher than the required temperature of the cold channel, the fan is stopped;

[0032] When it is necessary to maintain the perforated anti-static floor 13 and the sealed anti-static floor 9, the hydraulic rod 25 can be opened, and the mounting frame 20 can be pushed to drive the moving wheel 21 to move downward, so that the moving wheel 21 contacts the floor, and the mounting seat 22 is lifted, thereby controlling the movement of the cabinet 11 module to facilitate maintenance of the floor. The size of the mounting seats 22 can be adjusted by movable connecting plates 24 and fixed plates 23, and can be adapted to the use of computer room frames 1 in different spatial ranges.
