Description

Condenser tube connecting method and condenser tube group The application relates to a patent application with the application number of 202411441990.2, the application number of 2024, 10-month and 16-day, and the name of 'a condensation pipe group, a falling film condenser adopting the condensation pipe group, a condensation method and a refrigeration system'. Technical Field The invention relates to the field of condensers, in particular to a condenser pipe connection method and a condenser pipe group. Background In a refrigeration system, an evaporator, a condenser, a compressor, and an expansion valve are four major components essential in the refrigeration system, among which the evaporator is a device that delivers cold. The refrigerant absorbs heat of the cooled object therein to realize refrigeration. The compressor is a heart and serves to suck, compress and deliver refrigerant vapor. A condenser is a device that gives off heat, transferring the heat absorbed in the evaporator to a cooling medium along with the heat converted by the compressor work. The expansion valve acts to throttle and depressurize the refrigerant while controlling and regulating the amount of refrigerant liquid flowing into the evaporator and dividing the system into two major parts, namely a high pressure side and a low pressure side. In addition to the four components, auxiliary devices such as solenoid valves, distributors, dryers, heat collectors, fusible plugs, pressure controllers and the like are often included in the actual refrigeration system, and are provided for improving the economy, reliability and safety of operation. The condenser is a part of a refrigerating system, belongs to a heat exchanger, and can convert gas or vapor into liquid, and transfer heat in a condensing tube into air near the condensing tube in a quick manner. The condenser operation is exothermic, so the condenser temperature is high. There are various types of condensation, and the water-cooled condenser uses water as a cooling medium, and takes away condensation heat by heating up the water. The cooling water is generally recycled, but a cooling tower or a cooling water tank is needed to be arranged in the system. The water-cooled condenser can be divided into a shell-and-tube condenser and a sleeve condenser according to the structural form, and is commonly known as a shell-and-tube condenser. The air-cooled condenser takes air as a cooling medium and takes away condensation heat by temperature rise of the air. The condenser is suitable for the occasion of extremely lack of water or no water supply, and is commonly used in a small freon refrigerating unit. The evaporating condenser is a main heat exchange device in a refrigerating system, and has the action principle that high-temperature high-pressure refrigerant gas discharged by a compressor in the refrigerating system passes through a condensing calandria in the evaporating condenser, so that high-temperature gaseous refrigerant exchanges heat with spray water and air outside the calandria. The gaseous refrigerant is gradually condensed into liquid refrigerant from top to bottom after entering the calandria from the upper opening. The super strong wind power of the matched induced draft fan enables the spray water to completely and uniformly cover the surface of the coil pipe, and the water is used for greatly improving the heat exchange effect by wind force. The spray water part with the temperature increased becomes a gas state, a great amount of heat is taken away by wind potential by utilizing the vaporization latent heat of the water, water drops in the hot air are blocked by the high-efficiency dehydrator, and the water drops and the rest water which absorbs the heat are scattered into the heat exchange layer of the PVC spray water sheet, cooled by the flowing air, the temperature is reduced, enter the water tank and are continuously circulated by the circulating water pump. The water evaporated into the air is automatically replenished by the water level regulator. The technology of the condenser is relatively mature after the development in recent years, but at present, at least the following defects still exist: 1. The existing evaporative condenser comprises a fan and a water distribution pipe at the top, wherein a condensing pipe is arranged below the water distribution pipe, a filler is arranged below the condensing pipe, a water tank is arranged below the filler, the water distribution pipe drains downwards, water flows downwards, an air inlet is arranged on the side surface of the water tank, the position of the air inlet is lower than that of the filler and the condensing pipe but higher than that of the water tank, when the fan is started, air is sucked from the air inlet from bottom to top, the sucked air firstly passes through the filler, the filler plays a role in guiding the air, the water flows downwards on the filler, and the water tank is arranged at the bottom an
