[0002] In recent years, the country has stepped up efforts to install elevators in old buildings, and installing elevators in old buildings has become a way for most old residential buildings to improve their quality of life. At present, the installed elevator shaft mainly uses a steel frame structure as the main body, and a glass curtain wall or aluminum plate is set outside the steel frame as the shaft wall. However, the elevator shaft of this structure has the characteristics of high temperature and difficulty in heat dissipation in summer, which further causes the temperature in the car to rise, affecting the passengers' experience. The current solution to the high temperature in the car is to install a ventilator or a refrigerator in the elevator, but the heat dissipation capacity of the ventilator is limited, and the heat generated by the refrigerator is still concentrated in the shaft, resulting in a significant reduction in the cooling effect of the car. At the same time, the high temperature in the shaft also affects the operation of the mechanical equipment in the elevator, and the aging of various parts is aggravated, and failures occur frequently.

[0003] Therefore, a device capable of cooling the elevator shaft is needed to solve the problem of poor heat dissipation effect of the existing elevator shaft. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Therefore, based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be noted that all the connection relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation; the embodiments and features and technical solutions in the embodiments of the utility model can be combined with each other without conflict. In addition, the terms "first", "second", "upper end", "lower end", "inner end", "outer end", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0030] An elevator shaft with heat dissipation function, referring to Figure 1-Figure 8As shown, it includes an elevator shaft 100, which is specifically composed of a steel frame as a main body, a rectangular channel is formed inside the steel frame, and a shaft curtain wall 120 is arranged outside the steel frame. The elevator shaft 100 has a car 140 in it, and a heat dissipation channel 130 is arranged on the side of the elevator shaft 100 away from the elevator door opening. The elevator door opening refers to the shaft opening corresponding to the car door, that is, the heat dissipation channel 130 is arranged on the side other than the door opening where the elevator is installed, and the heat dissipation channel 130 is connected to the outside of the elevator shaft 100, that is, it is connected to the atmosphere outside the elevator shaft 100. A refrigeration device 150 is arranged on the top of the car 140, and the refrigeration device 150 has a heat exhaust duct 1514, wherein the heat exhaust duct 1514 is always connected to the heat dissipation channel 130 during the operation of the elevator, so as to discharge the heat discharged by the refrigeration device 150 to the atmospheric environment outside the elevator shaft 100, and will not cause the heat in the elevator shaft 100 to continue to accumulate.

[0031] Furthermore, the elevator shaft 100 has a shaft curtain wall 120 on the outside, and the heat dissipation channel 130 is formed at a corner of the shaft curtain wall 120. Specifically, the shaft curtain wall 120 includes a front where the elevator door opening is located, a back side corresponding to the front and rear of the elevator door opening, and two side sides. Specifically, the heat dissipation channel 130 is formed at the junction of the back side and one of the side sides. The purpose of such a setting is mainly to consider that there are many components such as steel frames, guide rails, and wire rope systems arranged in the shaft, and the above-mentioned components need to be avoided. The junction of the back side and the side side has a corresponding space for setting the heat dissipation channel 130, and the heat dissipation channel 130 is connected from top to bottom. Preferably, the heat dissipation channel 130 extends upward to the upper part of the top floor and downward to the upper part of the first floor. The temperature of the first floor is generally lower, and the elevator is parked on the first floor. The refrigeration device 150 is located on the top of the car 140. Therefore, the heat dissipation channel 130 extends downward to the upper part of the first floor.

[0032] Furthermore, the heat dissipation channel 130 is a channel with a rectangular cross-section, and the channel has a channel wall 131. Specifically, the channel wall 131 formed on the shaft curtain wall 120 is a shutter 133, which can prevent rainwater from entering the shaft and discharge heat at the same time. In addition, the channel wall 131 formed in the elevator shaft 100 includes a sealing plate on one side and a barrier formed by a brush assembly 132 on the other side. The brush assembly 132 is used to achieve relative isolation between the elevator shaft 100 and the heat dissipation channel 130.

[0033] Furthermore, the refrigeration device 150 includes a refrigeration main unit 151, and one side of the refrigeration main unit 151 has an air inlet 1511 and a cold air outlet 1512; specifically, the refrigeration main unit 151 is modified from an existing refrigeration window air conditioner, and specifically, the other side of the refrigeration main unit 151 is provided with an air collecting hood 1513, and the air collecting hood 1513 is connected to a heat exhaust air duct 1514, and the air collecting hood 1513 is adapted to the heat exhaust port at the rear of the refrigeration main unit 150. An opening is provided on the air collecting hood 1513, and the opening is used to connect the heat exhaust air duct 1514. The heat exhaust air duct 1514 is used to extend into the brush assembly 132, and is used to discharge the heat generated by the refrigeration main unit 150 to the elevator shaft 100.

[0034] Furthermore, the heat exhaust air duct 1514 includes at least one bend, and multiple bends may also be provided, which is specifically determined according to the installation space of the well.

[0035] Further, such as Figure 7 , Figure 8 As shown, the bristle assembly 132 includes two bristle seats 1322 symmetrically arranged on the left and right, and the two bristle seats 1322 are spaced apart from each other. Bristles 1321 are arranged on one side of the bristle seat 1322 extending along the length direction. The bristles 1321 installed on the two bristle seats 1322 are arranged opposite to each other and the ends of the bristles 1321 are in contact with each other. The bristles 1321 are used to isolate the elevator shaft 100 and the heat dissipation channel 130. Although the flow of hot air cannot be completely isolated, most of the heat can be isolated and the hot air is discharged to the outside of the elevator shaft 100.

[0036] Further, such as Figure 8 As shown, the bristles 1321 are provided with two layers. Specifically, the two layers of bristles 1321 are arranged along the extension direction of the heat exhaust air duct 1514, that is, two bristle barriers are formed, which are used to relatively isolate the heat of the elevator shaft 100 and the heat dissipation channel 130. Specifically, the bristles 1321 are made of polypropylene plastic wires and have a certain hardness and elasticity, ensuring that the heat dissipation air duct 1514 will not encounter greater resistance when moving up and down, and at the same time ensuring that the heat exhaust air duct 1514 can return to a horizontal state after breaking contact with the bristles 1321, and continue to isolate the elevator shaft 100 and the heat dissipation channel 130.

[0037] Furthermore, the top of the elevator shaft 100 has an equipment layer 110 , the equipment layer 110 has an upper ventilation window 111 , and the first floor of the elevator shaft 100 has a lower air inlet 112 .

[0038] Furthermore, a temperature sensor is provided in the equipment layer 110 , and an exhaust fan is provided at the upper ventilation window 111 .

[0039] When the elevator shaft 100 of the utility model is working, if the temperature sensor senses that the temperature in the elevator shaft 100 exceeds the set value, the hot air in the upper part of the shaft is first discharged from the shaft through the upper ventilation window 111 through the exhaust fan to perform preliminary heat dissipation. At this time, the wind with a lower temperature at the bottom of the shaft enters the shaft from the lower air inlet 112. At the same time, the refrigeration device 150 is started to directly cool the air in the shaft. The elevator shaft 100 can also be cooled when it is running up and down. The component 132 is composed of two groups of bristles 1321 arranged opposite to each other. The dense bristles 1321 form an isolation barrier, but a gap is formed in the middle. Since the bristles 1321 can be bent, the heat exhaust air duct 1514 can be extended into the bristle component 132 and connected with the heat dissipation channel 130. When the elevator is running up and down, the heat exhaust air duct 1514 will open the bristles 1321 in the upper and lower positions, enabling up and down operation, ensuring that the entire elevator shaft 100 achieves uninterrupted cooling at all height levels.

[0040] The utility model is an elevator shaft equipped with a heat dissipation function. A refrigeration device that can actively cool down is arranged in the elevator to cool the hot air in the shaft, thereby effectively reducing the temperature in the shaft. At the same time, the refrigeration device has an air collecting hood for collecting hot air generated after the refrigerated air is cooled. The air collecting hood is connected with a heat exhaust duct. At the same time, heat dissipation channels are arranged at the corners of the shaft wall. The heat exhaust duct discharges the hot air exhausted by the refrigeration device to the heat dissipation channel, thereby avoiding further accumulation of heat in the shaft, and truly achieving the purpose of cooling and dissipating the heat of the elevator shaft.

Although the above embodiments describe the utility model in detail, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
