Description
Technical Field
The invention relates to ventilation and current conversion heat exchange equipment, in particular to a plane plate type heat recovery ventilation device with reduced wind resistance, high heat recovery efficiency and no extra energy loss.
Background
In the space of various industries, production and living places, as long as personnel flow, air conversion operation is inevitably needed to keep the carbon-oxygen ratio of air. Especially in the indoor and outdoor environment interfaces of various buildings, by additionally arranging the ventilation device, the adjustment result of optimizing the air quality can be obtained by utilizing the function combination of the ventilation device besides creating the interaction space of fresh air and indoor foul air. Especially in some areas and seasons, the temperature difference between the indoor and the outdoor is often as high as more than 10 ℃, the direct ventilation can unbalance the indoor environment temperature, the comfort of indoor personnel is not affected under severe fluctuation, and the energy consumption investment for adjusting the room temperature can be increased.
At present, the heat recovery mode in the ventilation field is more, and the heat recovery mode is typically two types of sandwich type heat exchangers and runner heat exchangers. The sandwich type heat exchanger can be divided into total heat exchange and sensible heat exchange according to different sandwich materials, and the main difference is whether water vapor can be separated by a return air interlayer. The common sandwich heat exchanger is manufactured by a layer-by-layer overlapping mode, and every two adjacent layers are not communicated with each other and are arranged by overlapping air supply and return air. The sandwich material is usually made of resin or special paper with good heat conduction efficiency, when the air is sent back to and passes through the two adjacent layers, heat conduction can be carried out on the sandwich material due to the temperature difference between the air supply and the air return, and the cold quantity or the heat quantity in the air exhaust is recovered, so that the energy-saving function is realized. However, the gaps between the interlayers are small, the wind resistance is large, and in order to improve the heat conduction efficiency, the interlayer material is generally thin and is easy to damage. Especially, for the heat exchange device adopting special paper as the interlayer, the heat exchange device can not be washed by water, and can only be discarded integrally in the later use if local blockage occurs, thereby causing extra resource waste.
At present, a commonly used rotary wheel type heat recovery device is mainly formed by winding and combining a corrugated aluminum base material, a heat storage ceramic body and the like into a wheel type structure, and a wheel type is divided into two parts along an axis: one part of the air continuously passes through the air supply, the other part of the air continuously passes through the air exhaust, and meanwhile, the rotating wheel continuously rotates under the driving of the motor. In the rotating process of the rotating wheel, the rotating wheel can store heat/cold in exhaust air by using the heat storage core material, and when the part of the heat storage core material rotates to the air supply side, the heat storage core material is used for preheating/precooling the air supply, so that the purpose of energy recovery is achieved. Because of the structural characteristics, the problem of large wind resistance also exists, and in order to ensure the air quantity of the system, the rotating wheel needs to be made large to meet the requirement. Although the motor power consumption of the rotating wheel is usually smaller than the heat recovered by the rotating wheel, the additional energy consumption is still caused by the increased output of the power element; and the rotating wheel is inconvenient to assemble and disassemble when using devices, the inner cavity can not be reliably cleaned basically, and the scrapping degree is relatively high.

Detailed Description
The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings for the purpose of understanding and controlling the technical solutions of the present invention, so as to define the protection scope of the present invention more clearly.
Aiming at the defects of the conventional common heat recovery ventilation device in practical application, the designer innovatively provides a plane plate type heat recovery ventilation device which can increase ventilation volume, improve heat recovery efficiency and prolong service life, depends on experience accumulation of equipment development in the fresh air industry, is widely suitable for indoor and outdoor ventilation in the environment with large temperature difference, and is beneficial to reducing energy consumption of indoor heat preservation.
As shown in fig. 1 to 4, firstly, in view of the structural features of the heat recovery ventilator of the present invention, the ventilator is mainly assembled by three parts, namely, a liquid-filled copper sealing tube 3, a heat dissipating aluminum fin 2 and an outer frame 1. It can be seen that the structure of the rotary wheel heat exchanger is greatly simplified compared with the structure of the rotary wheel heat exchanger, and the function of the rotary wheel heat exchanger is not inferior to that of the ventilation equipment adopting various traditional structural principles. The outer frame 1 is a rectangular window frame formed by connecting five frame rods, wherein an air supply channel A and an air exhaust channel B (named temporarily) are arranged side by side and are separated, a plurality of first through holes 111 are distributed in the middle frame rod 11 for separating the two channels along the length direction, and the axial direction of each first through hole 111 is vertical to the middle frame rod 11 and is opposite to the lateral frame rods 12. The heat dissipating aluminum fins 2 are parallel to the middle frame rod and are densely arranged in the outer frame 1 at uniform intervals, and each heat dissipating aluminum fin 2 is provided with a second through hole 21 which penetrates through the surface and is coaxial with the first through hole 111. The sealing copper pipe 3 is a closed pipe fitting filled with fluorinated cooling liquid, and the fluorinated cooling liquid occupies half of the space in liquid state and gaseous state in the inner cavity of the sealing copper pipe at normal temperature. The number of the copper sealing tubes 3 corresponds to the number of the holes of the first through holes 111, and for any copper sealing tube, the copper sealing tube is connected to the second through holes 21 of the heat dissipation aluminum fins 2 and the first through holes 111 of the middle frame rod 11 layer by layer, and two ends of the copper sealing tube 3 are respectively abutted against the lateral frame rods 12 to be kept in position, so that the heat dissipation aluminum fins, the outer frame and the copper sealing tube are combined into an integrated device which cannot be easily scattered.
It should be added to the above summary schemes that the above outer frame is formed by assembling five frame rods, which is only a preferred forming structure of the present invention, and aims to satisfy structural adaptation of a general assembly mode of a sealing copper tube and a heat dissipation aluminum fin. Briefly speaking, the general assembly method comprises the steps of firstly completing liquid filling and complete sealing of a copper pipe, then inserting the copper pipe into a first through hole and enabling exposed parts on two sides to be equal in length, then axially aligning a second through hole at the corresponding position of a radiating aluminum fin with a sealing copper pipe, sleeving the second through hole on two sides of the sealing copper pipe one by one, and preliminarily adjusting and positioning according to the preset interval of the radiating aluminum fin; then, the lateral frame rods are abutted to the end parts of the sealing copper tubes from two sides, the sealing copper tubes are limited in an initial equal interval and left-right alignment mode, finally, the top side frame rods of the outer frame are abutted from the tops of the heat dissipation aluminum fins, the bottom side frame rods are abutted from the bottoms of the heat dissipation aluminum fins, and four external frame rods are connected and fixed at four corners of the outer frame. Therefore, the sealing copper tube and the radiating aluminum fin are completely and firmly limited in the assembling process of the outer frame.
To achieve the desired function of the invention and to achieve structural stability of the final assembly of the product described above. The heat recovery ventilation unit also has further refined optimization features, as described below.
First, the boiling point of the fluorinated coolant filled in the copper seal tube 3 was set at 41 ℃, and the fluorinated coolant was easily volatilized. When exhaust air (such as winter scenes, the exhaust air is hot air) blows over the exhaust surface, the fins and the copper pipes absorb heat in the exhaust air, the liquid fluorinated coolant 41 is evaporated into gaseous fluorinated coolant 42, the gaseous fluorinated coolant overcomes the action of gravity and rises to a steam area at the upper half part of the sealed copper pipe, meanwhile, cold air flows through the air supply side, so that part of steam in the sealed copper pipe close to the cylinder wall in the air supply area is condensed into liquid drops 43, and the liquid drops flow into a liquid area at the lower half part of the sealed copper pipe again. The liquid level is automatically maintained at the same level in the liquid zone by gravity, and therefore the fluorinated coolant falling back from the liquid droplets 43 to the liquid zone is returned to the exhaust side. The circulation is repeated, and the heat recovery in the exhaust air is realized (in summer, vice versa, and the repeated description is omitted).
Next, in order to isolate the two channels, the two-way airflow cannot directly contact, a sealing rubber ring (not shown, sealing means of conventional ring contact) is provided between the first through hole 111 and the penetrating section of the sealing copper tube. Of course, the sealing can also be realized by adopting the circumferential welding of the connected positions, but the process control difficulty is increased and the operability is reduced.
Furthermore, the surface of the lateral frame rod 12 facing the copper sealing tube is provided with a cylindrical groove 121 for positioning and accommodating the copper sealing tube therein. The design structure can enhance the stability of the sealing copper pipe in final assembly finished equipment, and avoid the shaking and noise generation of the sealing copper pipe caused by the increase of the ventilation rate. Meanwhile, the opposite surface of the top side frame rod 13 of the outer frame facing the bottom side frame rod 14 is provided with a first positioning groove 131 for defining the assembly interval of the heat dissipation aluminum fins, and similarly, the opposite surface of the bottom side frame rod 14 facing the top side frame rod 13 is also provided with a second positioning groove 141, so that the two ends of all the heat dissipation aluminum fins connected by the sealing copper pipes in a penetrating way are jointed in the two positioning grooves, and the assembly and use stability is realized.
As shown in fig. 3, the flat panel heat recovery ventilation unit of the present invention is proposed in a conventional application, i.e., a flat horizontal type installation. In this state, the heat/cold recovery can be realized by passing cold or hot air from either side of the air supply channel, so that the air supply channel can be switched and adapted to the air exhaust channel. In the embodiment, the sealing copper pipe is transversely arranged, and the assembly structure of the radiating aluminum fin is combined, so that the whole volume is greatly reduced, and the air passing area is effectively increased. Referring to the state change of the fluorinated cooling liquid in the sealed copper pipe shown in fig. 2, the cooling or heat recovery mode is used for conducting heat in the sealed copper pipe, the conduction efficiency is high, and no extra energy loss exists while the energy in the exhaust air is recovered.
As shown in fig. 4, it is an alternative application of the ventilation unit of the present invention to fill it, i.e., to support a flat-faced, vertical window-type assembly. However, in this embodiment, the cold air area and the hot air area need to be selected according to the temperature property between the air exhaust and the air supply, that is, the device is turned over by 90 degrees in the drawing, so that the middle frame rod is horizontally arranged and all the copper sealing pipes are vertically erected. Taking a winter scene as an example and taking a middle frame rod as a boundary, when a lower hot air area exhausts air, the lower section of the aluminum fin and the sealing copper pipe absorb heat, the fluorinated cooling liquid in the lower hot air area is gradually evaporated into a vapor state and rises to a cold air area which is arranged at the upper side for supplying air, and when the air with lower temperature flows through the cold air area, the vapor state fluorinated cooling liquid is condensed into liquid drops again through the heat dissipation fin and the upper section of the sealing copper pipe, and the liquid drops fall back to a liquid area at the lower section of the sealing copper pipe.
Of course, the plane plate type heat recovery ventilation device assembled by the outer frame, the sealing copper pipe and the heat dissipation aluminum fin is not limited to the above assembly mode and the outer frame structure. For example, on the premise that the metal plate forming process is satisfied, the outer frame may be integrally formed into a pair of forming members half-and-half in the thickness direction, and the first through hole, the cylindrical groove, and the positioning groove in the half-opened shape may be formed at corresponding positions on the pair of forming members by secondary machining. When the product is assembled, one of the formed parts is used as a substrate, the primarily assembled sealing copper pipe and the radiating aluminum fin are in contraposition scarf joint, the positioning accuracy of each slot position and each hole position is checked, and the other formed part is used as a cover plate and is in contraposition joint with four sides of the substrate and fastened into a whole under the condition that the check is accurate.
In conclusion, the scheme introduction and the embodiment detail of the heat recovery ventilation device with the brand-new and optimized structure can be seen, and the scheme has prominent substantive features and remarkable progressiveness, and the scores are as follows.
1. The ventilation device adopts a structure that the sealing copper tube is transversely arranged and is combined with the radiating aluminum fin, thereby effectively reducing the wind resistance, being beneficial to greatly reducing the whole volume and obtaining the increase of the area of the overfire wind, and obtaining the expected ventilation volume in the limited space range.
