Description

Heat pipe fan heater

Technical Field

The invention relates to the technical field of circulating water cooling, in particular to a heat pipe fan heater.

Background

Currently, evaporative cooling devices and air cooling devices are mainly available in the cooling device market. The evaporative cooling device comprises a cooling tower, a closed tower, an evaporative cooler, an air cooler (island) and the like. When the external temperature is higher, the evaporation rate of the evaporative cooling device is higher, and the heat exchange capacity of the non-evaporative cooling device is reduced; when the external environment temperature is lower, the cooling device can be frozen and burst, the water vapor at the outlet or the water vapor at the air inlet of the wet cooling device can be condensed into fog when meeting cold, and can cause freezing in the downwind direction to influence the environmental sight and road traffic; dust storm and other foreign objects need to be prevented when there are more insects or when the external wind speed is high.

For a circulating water field designed according to national standards, in order to maintain the salt content of circulating water, a part of circulating water, called sewage, needs to be drained, and the part of circulating water generally accounts for about 0.5% of the circulating water. Even without this portion of the effluent, the owner has other effluents that require abatement to reduce the impact on the environment.

Disclosure of Invention

The invention aims to provide a heat pipe fan heater which can reduce the evaporation rate of wet cold water vapor and has a water-saving effect.

In order to solve the technical problems, the invention provides a heat pipe fan heater which comprises a cooling tower body, a cold water tank and an auxiliary cooling device, wherein the cold water tank is arranged below the cooling tower body, the auxiliary cooling device is arranged at an air inlet of the cooling tower body, an air duct and an air cooler are arranged on the cooling tower body, a hot water return pipe is arranged on the air cooler, the auxiliary cooling device comprises a spraying device, a water source, a heat exchange device, a plurality of water pipes and a sewage tank, the spraying device is connected with the water source through the water pipes, the sewage tank is arranged below the spraying device, the heat exchange device comprises a water inlet pipe, and the water inlet pipe is connected with the hot water return pipe.

In order to better cool the equipment, the invention improves that the heat exchange device is a light pipe.

In order to better cool the equipment, the invention improves that the heat exchange device is a finned tube.

In order to better utilize water resources, the invention improves the method that the water resources are sewage, sewage or tap water.

The invention has the beneficial effects that: the invention has novel design and simple structure, and has the following characteristics:

(1) the auxiliary cooling device reduces the temperature of air entering the air cooler, increases the relative humidity of the air cooler, reduces the heat load of the air cooler, and can reduce the water supplement amount of the air cooler to achieve the purpose of saving water.

(2) When the cooling tower needs to be prevented from freezing, the reduction of the amount of spray water or the direct closing of the spray water can be considered, the temperature of air entering the cooling tower is increased, the ambient temperature of the air inlet of the cooling tower and the bottom of the filler is increased to melt or prevent ice, the cooling tower can be considered to be closed when the external temperature is very low, and only the auxiliary cooling device is opened.

(3) The fact that the auxiliary cooling device can be used as a device capable of performing pure dry cooling and evaporative cooling is that when the auxiliary cooling device is used together with a cooling tower, fog dissipation can be achieved, and especially when the external temperature is very low, fog-free and 100% water-saving rate can be achieved when only dry cooling part operates but not wet cooling operation.

(4) Because the sewage is sprayed and evaporated, part of the sewage can be reduced, the temperature of the sewage is increased, the sewage treatment is facilitated, and the heat preservation cost of the sewage in winter can be reduced.

(5) The heat exchange capacity of the air cooler is in direct proportion to the temperature difference of the fluid inside and outside the pipe, and the fluid outside the pipe is air. Under the low humid environment of high temperature in summer, auxiliary cooling device can reduce the ambient air temperature who gets into the air cooler and increase its relative humidity to make air cooler heat transfer ability improve, simultaneously because auxiliary heat transfer device is wet cold, can accomplish partly heat load, make the temperature of intraductal technology fluid lower, can accomplish the cooling task better.
