[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0027] See also Figures 1 to 7 The embodiment of the present application provides a latent heat recovery device for a drying room, comprising a housing 1, a shutter assembly 13, a heat exchanger 2 and an automatic air inlet adjustment mechanism 3. A humid air inlet interface 11 is provided at one end of the housing 1, a humid air outlet 12 is provided at the other end of the housing 1, and a shutter assembly 13 is provided on the humid air outlet 12; a heat exchanger 2 is provided in the housing 1, and the heat exchanger 2 is arranged at one end close to the humid air inlet interface 11, and the heat exchanger 2 includes a plurality of heat exchange chips 21 arranged in an upper and lower interval arrangement, and a ventilation channel 22 is provided on the side of the heat exchange chip 21; a cold air outlet 15 is provided on one side of the housing 1, and a cold air inlet 16 is provided on the other side of the housing 1, and the cold air outlet 15 and the cold air inlet 16 are symmetrically arranged on both sides of the heat exchanger 2.
[0028] Furthermore, the heat exchange chip 21 can be made of aluminum. Aluminum is a good conductor of heat, and its thermal conductivity is three times greater than that of iron. Aluminum can be used in industry to manufacture various heat exchangers, heat dissipation materials, and cooking utensils.
[0029] Working principle and effect: Before use, install the heat recovery device on the drying room, so that the wet air inlet interface 11 of the heat recovery device is connected with the exhaust outlet of the drying room, and the cold air outlet 15 of the heat recovery device is connected with the air inlet of the internal circulation air system of the drying room. During use, the wet air in the drying room enters into the heat exchanger 2 through the wet air inlet interface 11 of the heat recovery device, and enters into the shell 1 through the gaps between the multiple heat exchange chips 21 spaced apart from each other, and finally is discharged to the outside of the shell 1 through the wet air exhaust outlet 12. The wet air passes through the heat exchange chip 21, and the heat carried therein will be transferred to the heat exchange chip 21, so that the temperature of the heat exchange chip 21 increases; at this time, due to the negative pressure generated by the internal circulation air system of the drying room, the cold air will be sucked into the shell 1 from the cold air inlet 16 located on one side of the shell 1, and will pass through the ventilation channel 22 on the heat exchange chip 21 (such as Figure 7When the cold air passes through the heat exchange chip 21 with an increased temperature, the heat exchange chip 21 will preheat the cold air, so that the cold air has a certain temperature when entering the heating system of the drying room, and a large amount of energy is not required to heat the cold air to the required temperature.
[0030] Compared with the prior art, the utility model recovers the heat carried by the humid air discharged from the drying room by setting a heat exchange chip 21, thereby effectively reducing the loss of heat energy. At the same time, the heat exchange chip 21 transfers the recovered heat to the newly incoming cold air, so that the cold air is preheated initially, thereby increasing the temperature of the cold air, thereby reducing the energy consumed when the preheated cold air enters the heating system of the drying room for further heating, thereby effectively reducing energy loss and consumption.
[0031] Furthermore, in the heat recovery device provided by the utility model, the wet air exhaust channel and the external air inlet channel can be unpowered settings. The wet air exhaust channel can use the positive pressure inside the drying room to exhaust the wet air; the external air inlet channel can use the negative pressure of the circulating air system in the drying room to inhale cold air; the structure is simple and the heat recovery effect is good.
[0032] In one embodiment, Figure 4 As shown, the heat exchange chip 21 is tilted, and the tilt direction is from the humid air inlet interface 11 to the humid air outlet 12. The tilted heat exchange chip 21 can prevent external water from entering, extend the heat exchange path, and increase the heat absorption effect of the heat exchanger 2; and after the humid air is cooled, the water vapor will condense, and the tilted heat exchange chip 21 can discharge the water adhering to the heat exchanger 2 to the water receiving tray 17.
[0033] In one embodiment, Figure 1 , Figure 5 and Figure 6As shown, the cold air inlet 16 is provided with an automatic air inlet adjustment mechanism 3, which includes a guide rail 31, a valve plate 32, a bracket 33, a rack 34, an electric actuator 35 and a gear 36. The guide rail 31 is arranged on the upper and lower sides of the cold air inlet 16, and the valve plate 32 is slidably connected to the guide rail 31. The valve plate 32 is provided with a rack 34. Both ends of the bracket 33 are installed on the shell 1, and the two ends of the bracket 33 are respectively located on the outer sides of the upper and lower guide rails 31. The inner side of the bracket 33 is provided with an electric actuator 35, and the electric actuator 35 is electrically connected to the gear 36. The gear 36 is meshed with the rack 34 through a rotating shaft. The automatic air inlet adjustment mechanism 3 is electrically connected to the control system, and the control system controls the movement of the valve plate 32, thereby controlling the switch of the cold air inlet 16. Specifically, the control system controls the electric actuator 35, and the electric actuator 35 controls the rotation of the gear 36. When the gear 36 rotates clockwise, the rack 34 engaged with the gear 36 will move in the direction close to the cold air inlet 16, thereby driving the valve plate 32 to move along the guide rail 31 in the direction close to the cold air inlet 16, so that the valve plate 32 moves to the cold air inlet 16 and blocks the cold air inlet 16; when the gear 36 rotates counterclockwise, the rack 34 engaged with the gear 36 will move in the direction away from the cold air inlet 16, thereby driving the valve plate 32 to move along the guide rail 31 in the direction away from the cold air inlet 16, thereby moving the valve plate 32 away from the cold air inlet 16 and opening the cold air inlet 16.
[0034] In one embodiment, Figure 4 As shown, a water receiving pan 17 is provided at the bottom of the shell 1, and a drain pipe 4 is provided at one end of the shell 1. The drain pipe 4 is located below the wet air outlet 12, and the water receiving pan 17 is connected to the drain pipe 4. After the humid air is cooled, the water vapor will condense on the heat exchange chip 21, and the condensed water will be smoothly discharged from the heat exchanger 2 by using the exhaust pressure of the wet air, and flow into the water receiving pan 17, and then discharged from the heat recovery device through the drain pipe 4.
[0035] In one embodiment, the shutter assembly 13 is configured as a non-powered self-closing shutter. When the drying room needs to be vented, the shutter will be pushed open by the exhausted humid air; when the drying room is not vented, the shutter automatically closes. The non-powered self-closing shutter can automatically adjust the opening and closing of the shutter according to whether the drying room needs to be vented. The structure is simple and effectively avoids the situation where the shutter is opened when the drying room does not need to be vented, causing energy loss.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
