Evaporative type condensation coil and evaporative type condenser

Technical Field

The utility model relates to a condenser, concretely relates to evaporation formula condenser coil and evaporation formula condenser.

Background

The condenser is one of main heat exchange devices in various industries such as food, chemical industry, pharmacy and the like, and has wide application. The evaporation type air conditioning technology is energy-saving, environment-friendly and sustainable in development, and effectively solves the problems of high initial investment, high running energy consumption and the like of the traditional mechanical refrigeration. The evaporative condenser is one of condensers, and is a high-power condensing device which takes away heat of a refrigerant by using forced air convection circulation and moisture evaporation. There is now an increasing number of people working on the use of evaporative condensers. The principle of the evaporative condenser is that circulating cooling water with small flow rate is evaporated on the outer surface of a condensing coil, and refrigerant gas is condensed into liquid in the condensing coil. At present, a commonly used condensing coil is formed by bending an internal tooth copper pipe, as shown in fig. 1 and fig. 2, a longer copper pipe is bent back and forth to form a snake-shaped loop, the number of middle welding spots is small, but the copper pipe still has the defects that the wall thickness of the copper pipe is not smaller than 1.2mm due to strength and erosion abrasion, so that the manufactured coil is large in size and needs a larger space. In addition, the refrigerant is not necessarily completely liquefied after being sprayed by the spraying device, and a gas-liquid mixed state exists, so that the heat exchange effect is poor. In most cases, the evaporation system needs to be equipped with a gas-liquid separator, which increases the equipment cost.

Detailed Description

The technical solution of the present invention is further explained with reference to the accompanying drawings.

The embodiment is as follows: as shown in fig. 3, the evaporative condenser coil according to the present invention comprises a first support tube 10 connected to a refrigerant inlet, a third support tube 30 connected to a refrigerant outlet, a second support tube 20 and a plurality of stroke pipelines 40, wherein the third support tube 30 is coaxially disposed below the first support tube 10, the second support tube 20 is disposed in parallel with the first support tube 10 and the third support tube 30, and the plurality of stroke pipelines 40 are connected in parallel between the first support tube 10 and the second support tube 20 and between the third support tube 30 and the second support tube 20.

The second support pipe 20 includes a first pipe 21 and a second pipe 22, the stroke pipe 40 includes a first stroke pipe 41 and a second stroke pipe 42, the first pipe 21 is communicated with the first support pipe 10 through a plurality of first stroke pipes 41, and the second pipe 22 is communicated with the third support pipe 30 through a plurality of second stroke pipes 42. Illustratively, one port of each first stroke conduit 41 is welded to the first conduit 21, and the other port is welded to the first support tube 10, forming a communicating passage; similarly, one port of each second travel tube 42 is welded to the second tube 22 and the other port is welded to the third support tube 30 to provide a passageway for communication.

Referring to fig. 4 and 5, the first support tube 10, the second support tube 20, and the third support tube 30 have a square cross section, and thus have a strong supporting function. The cross section of the stroke pipeline 40 (including the first stroke pipeline 41 and the second stroke pipeline 42) is circular, so that the manufacturing is convenient, meanwhile, the large contact area with the spray cooling water can be ensured, and the cooling effect is improved. The length of the first support tube 10 is greater than that of the third support tube 30, and the refrigerant gas can be sufficiently heat-exchanged in the plurality of first stroke lines 41.

Gaseous refrigerant enters the first supporting pipe 10 through the inlet, then flows into the stainless steel pipe communicated with the first supporting pipe 10, is liquid through the evaporation cooling of the spraying system, flows into the second supporting pipe 20 welded at the other side, but in the process, the completely liquefied state can not be achieved, a gas-liquid mixed state exists, under the action of gravity, the completely liquefied refrigerant in the second supporting pipe 20 flows into the bottommost end of the pipeline firstly, then flows into the third supporting pipe 30 through the lower second stroke pipeline 42, flows out through the outlet, and the original gas-liquid mixed liquid flows into the first supporting pipe 10 through the plurality of first stroke pipelines 41 in the second supporting pipe 20, and is sprayed and cooled again in the advancing process. Thus, the heat exchange is more uniform, the utilization rate of the refrigerant is greatly improved, and the heat exchange effect can be improved.
