Description

Technical Field

[0001] The invention relates to a ventilator, in particular to a ventilator capable of reducing air temperature. Background Art

[0002] At present, mining ventilators do not have refrigeration devices. As the depth of the mine increases, the temperature underground increases accordingly, reaching above 30°C. Since workers perform heavy physical labor in a high temperature and high humidity environment for a long time, their work efficiency is reduced and safety risks are increased. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a ventilator that can reduce the air temperature.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: A ventilator capable of reducing air temperature comprises an elbow silencer, an inlet silencer, a main unit, an outlet silencer and an air cooler, and is characterized in that: the air cooler comprises a connecting flange, a heat-absorbing thin-walled copper tube, a cold water inlet, an air cooler shell, a return water outlet, a wind tube fixing ring and a condensate drain outlet; the air cooler shell is connected with a connecting flange and a wind tube fixing ring; the air cooler shell is provided with a cold water inlet, a return water outlet and a condensate drain outlet; the air cooler shell is provided with a heat-absorbing thin-walled copper tube, one end of the heat-absorbing thin-walled copper tube is connected with the cold water inlet, and the other end of the heat-absorbing thin-walled copper tube is connected with the return water outlet; the connecting flange of the air cooler is connected with the outlet silencer of the ventilator.

[0005] When in use, cold water enters the heat-absorbing thin-walled copper tube in the air cooler from the cold water inlet, the main engine transports air to the air cooler, and the high-temperature air contacts the heat-absorbing copper tube inside the air cooler. The heat of the high-temperature air is transmitted to the cold water inside through the copper tube, and the heat is taken away by the cold water in the copper tube. After heat exchange, the air temperature at the air outlet drops to a temperature suitable for the human body, and then is transported to the work surface through the air duct; the condensed water produced outside the heat-absorbing thin-walled copper tube in the air cooler gathers at the bottom of the air cooler outlet and is discharged through the condensed water drain outlet.

[0006] Compared with the prior art, the beneficial effects of the present invention are: the air temperature at the air outlet is reduced to a temperature suitable for the human body, the environment is comfortable, the work efficiency is improved, and the safety risk is reduced.
