Description

Technical Field

[0001] The utility model relates to the technical field of air cooler appliances, in particular to an antifreeze mechanism for an air cooler. Background Art

[0002] An air cooler is a device that uses ambient air as a cooling medium and sweeps across the outside of the finned tubes to cool or condense the high-temperature process fluid in the tubes. It is referred to as an "air cooler" or "air-cooled heat exchanger."

[0003] Air coolers with steam as the medium in the tubes have a problem in cold winter weather. If the cooling fan is turned on, the tubes will be blocked by freezing due to low temperature. If the cooling fan is not turned on, steam binding will easily form in the tubes, which will also cause freezing and blockage.

[0004] The prior art discloses a patent CN207066169U, which includes a frame, a bellows, a process tube bundle, a steam heating tube bundle, a side beam and a motor. The frame is provided with a bellows and a side beam, the air inlet of the bellows is provided with a motor, a process tube bundle is provided above the bellows, the process tube bundle is located at the air inlet of the air cooler, the steam heating tube bundle is also arranged at the air inlet of the air cooler, and the steam heating tube bundle is located below the process tube bundle; the steam heating tube bundle and the process tube bundle are independent of each other; the steam heating tube bundle adopts a single-row tube-one-flow arrangement. The utility model can work normally when the ambient temperature is low, and the fluid in the tube will not solidify or freeze.

[0005] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0006] Air coolers are equipment normally used in industrial equipment. They have complex structures and complex media, and are more prone to damage, leakage and other problems. Especially in winter operation, due to misoperation, structural blockage and other reasons, it is very easy to cause the medium to freeze, freeze the tube bundle, cause equipment damage, and make the device unusable.

[0007] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In view of the defects in the prior art, the utility model provides an air cooler antifreeze mechanism to solve the problem that the air cooler in the traditional technology, especially in winter operation, is very likely to cause the medium to freeze due to misoperation, structural blockage, etc., which will freeze and crack the tube bundle, causing damage to the equipment and making the device unusable.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] The air cooler antifreeze mechanism comprises a flow rate sensor connected to the flange of the air cooler, and an alarm and an outdoor temperature sensor are also fixedly arranged on the outside of the air cooler.

[0011] As an optimized solution, a mainstream pipe is connected to the flange of the air cooler, a branch pipe is connected in parallel to the mainstream pipe, and the flow velocity sensor is installed on the branch pipe.

[0012] As an optimized solution, a mainstream pipeline on-off valve is connected to the mainstream pipeline.

[0013] As an optimized solution, the main pipeline is fixedly connected with a first connecting tube and a second connecting tube in parallel along the liquid flow direction, and both ends of the branch pipeline are connected to the first connecting tube and the second connecting tube.

[0014] As an optimized solution, a branch pipeline on-off valve is fixedly connected to the first connecting tube.

[0015] As an optimized solution, the branch pipeline includes a first elbow and a second elbow arranged in parallel, one end of the first elbow is connected to the first connecting tube, and one end of the second elbow is connected to the second connecting tube.

[0016] As an optimized solution, two ends of the flow velocity sensor are correspondingly connected to the other end of the first elbow and the other end of the second elbow.

[0017] As an optimized solution, the alarm and the outdoor temperature sensor are connected to the outer wall of the second elbow.

[0018] As an optimized solution, the outer wall of the second elbow is fixedly connected with a connecting plate through a clamp, and the alarm and the outdoor temperature sensor are connected to the connecting plate.

[0019] As an optimized solution, the connection plate is evenly provided with fixing holes, and the alarm and the outdoor temperature sensor are fixed to the fixing holes by means of bolts.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] Add a flow rate sensor to the flange of the existing air cooler to measure the flow data of the cooling medium. Add an outdoor temperature sensor and an alarm to the outside of the air cooler. During actual use, when the outdoor temperature sensor measurement data is lower than the freezing point of the medium, and the flow rate sensor data is lower than 1m / s or a related low flow rate value, the alarm will warn and send a signal to ensure that the risk is eliminated;

[0022] When the ambient temperature drops, such as in winter, when there is icing, close the on-off valve of the mainstream pipeline and open the on-off valve of the branch pipeline to allow the medium to be transported along the branch pipeline and pass through the flow velocity sensor to measure the flow velocity and determine whether there is a risk of icing;

[0023] By setting up the mainstream pipeline and the branch pipeline, when the external temperature is high and there is no icing, the mainstream pipeline on-off valve is opened and the branch pipeline on-off valve is closed, so that the medium is transported along the mainstream pipeline, which can reduce the number of times the flow velocity sensor is used and extend its service life.

The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0028] like Figure 1 As shown, the air cooler antifreeze mechanism includes a flow rate sensor 1 connected to the flange of the air cooler, and an alarm 2 and an outdoor temperature sensor 3 are also fixedly provided on the outside of the air cooler.

[0029] A mainstream pipeline 4 is connected to the flange of the air cooler, a branch pipeline is connected in parallel to the mainstream pipeline 4, and a flow velocity sensor 1 is installed on the branch pipeline.

[0030] The mainstream pipeline 4 is connected to a mainstream pipeline on-off valve 8 .

[0031] The main pipeline 4 is fixedly connected with a first connecting tube 5 and a second connecting tube 6 in parallel along the liquid flow direction, and both ends of the branch pipeline are connected to the first connecting tube 5 and the second connecting tube 6 .

[0032] A branch pipeline on-off valve 7 is fixedly connected to the first connecting tube 5 .

[0033] The branch pipeline includes two first elbows 9 and second elbows 10 arranged in parallel, one end of the first elbow 9 is connected to the first connecting tube 5 , and one end of the second elbow 10 is connected to the second connecting tube 6 .

[0034] Two ends of the flow velocity sensor 1 are connected to the other end of the first elbow 9 and the other end of the second elbow 10 respectively.

[0035] The alarm 2 and the outdoor temperature sensor 3 are connected to the outer wall of the second elbow 10 .

[0036] The outer wall of the second elbow 10 is fixedly connected with a connecting plate 12 via a clamp 11 , and the alarm 2 and the outdoor temperature sensor 3 are connected to the connecting plate 12 .

[0037] The connecting plate 12 is evenly distributed with fixing holes, and the alarm 2 and the outdoor temperature sensor 3 are fixed to the fixing holes by means of bolts.

[0038] The second connecting tube 6 may be provided with an on-off valve for use in maintenance of the flow velocity sensor 1 to ensure that the medium can be transported along the mainstream pipeline 4 .

[0039] The working principle of this device is:

[0040] A flow rate sensor 1 is added to the flange of the existing air cooler to measure the flow data of the cooling medium. An outdoor temperature sensor 3 and an alarm 2 are added to the outside of the air cooler. During actual use, when the data measured by the outdoor temperature sensor 3 is lower than the freezing point of the medium, and the data of the flow rate sensor 1 is lower than 1m / s or a related low flow rate value, the alarm 2 warns and sends a signal to ensure that the risk is eliminated;

[0042] By setting up the mainstream pipeline 4 and the branch pipeline, when the external temperature is high and there is no icing, the mainstream pipeline on-off valve 8 is opened and the branch pipeline on-off valve 7 is closed, so that the medium is transported along the mainstream pipeline 4, which can reduce the number of times the flow rate sensor 1 is used and extend its service life.
