Description

Technical Field

[0001] The utility model relates to the field of water chillers, in particular to a high-efficiency air-cooled water chiller. Background Art

[0002] A chiller is a refrigeration device used to provide cold water or coolant for various applications. It reduces the temperature of the fluid or air that needs to be cooled by absorbing heat and dissipating it to the external environment. Chillers are widely used in various fields, such as industrial process cooling, air conditioning systems, medical equipment, electronic equipment cooling, etc. They can provide stable cooling performance and can adjust the temperature and flow of cold water or coolant as needed.

[0003] Chillers are widely used, but they still have some problems: 1) Air-cooled chillers only rely on cooling fans and fins to dissipate heat, and the heat dissipation efficiency is limited. In some extreme environments, the temperature cannot be reduced to the specified range; 2) During the operation of air-cooled chillers, their air-cooling structure is easily contaminated by dust and impurities and becomes blocked, requiring regular and frequent cleaning, and is difficult to maintain; Therefore, in view of the above situation, there is an urgent need to develop a high-efficiency air-cooled chiller to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency air-cooled chiller to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The high-efficiency air-cooled chiller comprises a chiller, an air-cooling component A and an air-cooling component B. The air-cooling component A and the air-cooling component B are both horizontally embedded and installed on the inner top of the chiller, and the air-cooling component B is located at the bottom of the air-cooling component A.

[0007] The air-cooling component A includes a filter, a cooling fan, a cooling component, cooling fins and a condenser. The cooling component is vertically embedded and installed in the middle position inside the chiller. The cooling fins are vertically arranged on one side of the cooling component, and the cooling fins are fixedly connected to the inner wall of the chiller. The top of the condenser is set through the inside of the cooling fins. The cooling fan is vertically arranged on the opposite side of the cooling fins and is fixedly connected to the cooling component by screws. The filter is vertically installed on one side of the cooling fan.

[0008] As a further solution of the utility model: the cooling component is composed of a plurality of wind guide plates which are vertically and equidistantly distributed.

[0009] As a further solution of the utility model: an air inlet slot and an air outlet slot are formed between two adjacent air guide plates, and the width of the air inlet slot is greater than that of the air outlet slot. Since the internal air duct gradually narrows, when the wind passes through the narrow channel, the cross-sectional area of ​​the channel is smaller, resulting in an increase in the wind flow rate. According to Bernoulli's principle, an increase in flow rate will lead to a decrease in static pressure, and the temperature is closely related to the pressure of the gas. A decrease in pressure will lead to a decrease in the gas temperature, thereby cooling the air passing through the air guide plates.

[0010] As a further solution of the utility model: the condenser includes a liquid inlet pipe, a transfer pipe A, a drain pipe, an electric control valve, a main condensation pipe network, a spare condensation pipe network, a transfer pipe B and a one-way valve. Two sets of transfer pipes A are vertically arranged on one side of the liquid inlet pipe, connected and fixed with the liquid inlet pipe, and the electric control valve is installed in the middle position of the liquid inlet pipe. Two sets of transfer pipes B are vertically arranged on one side of the drain pipe, connected and fixed with the drain pipe. The one-way valve is installed in the middle position of the drain pipe. The main condensation pipe network and the spare condensation pipe network are horizontally installed between the two sets of transfer pipes A and the transfer pipe B. It has two sets of condensers, which can effectively improve the heat dissipation efficiency.

[0011] As a further solution of the utility model: the main condensation pipe network and the spare condensation pipe network are composed of a number of equidistantly distributed condenser pipes, and the spare condensation pipe network is located on the top of the main condensation pipe network. The main condensation pipe network and the spare condensation pipe network are set up in conjunction with the cooling fins to quickly dissipate heat.

[0012] As a further solution of the utility model: the liquid inlet pipe, the transfer pipe A, the main condensing pipe network, the transfer pipe B, and the drain pipe are connected in sequence; the liquid inlet pipe, the electric control valve, the transfer pipe A, the spare condensing pipe network, the transfer pipe B, the one-way valve, and the drain pipe are connected in sequence; the electric control valve and the one-way valve are arranged to control whether the spare condensing pipe network is connected, and the spare condensing pipe network can be activated when the cooling rate needs to be increased.

[0013] Beneficial effects: This high-efficiency air-cooled chiller is equipped with a cooling component. The special air duct design of the cooling component can initially cool the air passing through the condenser, thereby improving the heat dissipation efficiency and meeting higher cooling requirements. It is equipped with two sets of air-cooling components. When necessary, the two sets of air-cooling components can be started at the same time for heat dissipation, thereby greatly improving the heat dissipation efficiency. A filter is installed at the air inlet end of the cooling fan to filter the air, preventing a large amount of dust and impurities from adhering to the cooling fins and affecting the heat dissipation effect, extending the maintenance cycle and reducing the difficulty of maintenance.

[0022] See also Figures 1 to 7 In the embodiment of the utility model, the high-efficiency air-cooled chiller includes a chiller 1, an air-cooling component A2 and an air-cooling component B3. The air-cooling component A2 and the air-cooling component B3 are both horizontally embedded and installed on the inner top of the chiller 1, and the air-cooling component B3 is located at the bottom of the air-cooling component A2;

[0023] The air-cooling component A2 includes a filter 21, a cooling fan 22, a cooling component 23, a cooling fin 24 and a condenser 25. The cooling component 23 is vertically embedded and installed in the middle position inside the chiller 1. The cooling fin 24 is vertically arranged on one side of the cooling component 23, and the cooling fin 24 is fixedly connected to the inner wall of the chiller 1. The top of the condenser 25 is set through the inside of the cooling fin 24. The cooling fan 22 is vertically arranged on the opposite side of the cooling fin 24 and is fixedly connected to the cooling component 23 by screws. The filter 21 is vertically installed on one side of the cooling fan 22.

[0024] As a further solution of the utility model: the cooling component 23 is composed of a plurality of air guide plates 231 which are vertically and equidistantly distributed.

[0025] As a further solution of the utility model: an air inlet slot 2311 and an air outlet slot 2312 are formed between two adjacent air guide plates 231, and the width of the air inlet slot 2311 is greater than the width of the air outlet slot 2312. Since the internal wind duct gradually narrows, when the wind passes through the narrow channel, the cross-sectional area of ​​the channel is smaller, resulting in an increase in the wind flow rate. According to Bernoulli's principle, an increase in flow rate will lead to a decrease in static pressure, and the temperature is closely related to the pressure of the gas. A decrease in pressure will lead to a decrease in the gas temperature, thereby cooling the air passing through the air guide plates 231.

[0026] As a further solution of the utility model: the condenser 25 includes a liquid inlet pipe 251, a transfer pipe A252, a discharge pipe 253, an electric control valve 254, a main condensation pipe network 255, a spare condensation pipe network 256, a transfer pipe B257 and a one-way valve 258. Two groups of transfer pipes A252 are vertically arranged on one side of the liquid inlet pipe 251, and are connected and fixed to the liquid inlet pipe 251. The electric control valve 254 is installed in the middle position of the liquid inlet pipe 251. Two groups of transfer pipes B257 are vertically arranged on one side of the discharge pipe 253, and are connected and fixed to the discharge pipe 253. The one-way valve 258 is installed in the middle position of the discharge pipe 253. The main condensation pipe network 255 and the spare condensation pipe network 256 are horizontally installed between the two groups of transfer pipes A252 and the transfer pipe B257. It has two groups of condensers, which can effectively improve the heat dissipation efficiency.

[0027] As a further solution of the utility model: the main condensing pipe network 255 and the spare condensing pipe network 256 are both composed of a number of equidistantly distributed condensing pipes, and the spare condensing pipe network 256 is located on the top of the main condensing pipe network 255. The main condensing pipe network 255 and the spare condensing pipe network 256 are set up in conjunction with the cooling fins 24 to quickly dissipate heat.

[0028] As a further solution of the utility model: the liquid inlet pipe 251, the transfer pipe A252, the main condensing pipe network 255, the transfer pipe B257, and the discharge pipe 253 are connected in sequence, the liquid inlet pipe 251, the electric control valve 254, the transfer pipe A252, the spare condensing pipe network 256, the transfer pipe B257, the one-way valve 258, and the discharge pipe 253 are connected in sequence, and the electric control valve 254 and the one-way valve 258 are arranged to control whether the spare condensing pipe network 256 is connected, and the spare condensing pipe network 256 can be activated when the cooling rate needs to be increased.

[0029] The working principle of the utility model is as follows: when the high-efficiency air-cooled chiller is in use, the cooling fan 22 of the air-cooling component A2 guides the external air through the filter 21 to the cooling component 23. After the air is initially cooled by the cooling component 23, the cooled cold air is discharged through the gaps between the heat dissipating fins 24. When the refrigerant of the chiller 1 flows through the condenser 25, its heat is transferred to the heat dissipating fins 24. When the cold air passes through the heat dissipating fins 24, the heat is discharged to the external air. It should be noted that when the air flows through the cooling component 23, the air will be discharged from the air guide. The refrigerant enters the air inlet slot 2311 of the plate 231, then passes through the gradually shrinking internal air duct, and is finally discharged through the air outlet slot 2312. During this process, the air temperature will decrease, achieving initial cooling. The refrigerant will flow through the liquid inlet pipe 251, the transfer pipe A252, the main condensing network 255, the transfer pipe B257, and the drain pipe 253 in sequence. When it is necessary to improve the cooling efficiency, the electric control valve 254 is opened. At this time, the refrigerant will also be diverted to the spare condensing network 256, and then flow back to the drain pipe 253 through the one-way valve 258, thereby extending the heat dissipation path to improve the heat dissipation efficiency.

[0030] 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.
