Anti-cooler overheating function by using condensed water}

The present invention relates to an apparatus for preventing overheating of an engine system using condensate, and more particularly, to store condensate generated from air exchanging heat with an evaporator in a heating, ventilation, and air conditioning (HVAC) system. An apparatus for preventing overheating of an engine system using condensate, which pumps when there is a risk of overheating and sprays it to the cooler front through a nozzle to protect the engine.

Conventionally, the cooling performance is improved to protect the engine from overheating. In general, to improve the cooling performance, a cooler size or a high specification fan should be used. Alternatively, a method of spraying water spray on the front of the cooler has been devised, but the user has to fill the water frequently, and there is a risk of the nozzle clogging or the cooler being contaminated by foreign substances in the water. there was.

The present invention has been developed to solve the above problems, and stores the condensate generated in the evaporator (evaporator) when operating the air conditioner, and senses the coolant temperature when the engine risks overheating (overheating), the stored condensate An object of the present invention is to provide an overheating prevention apparatus of an engine system using condensate, which is prevented from overheating of the engine by pumping and spraying the cooler module in front of the cooler module through a nozzle.

An apparatus for preventing overheating of an engine system using condensate according to the present invention for achieving the above object,

A water tank that stores condensate (water generated by condensation of moisture in the air) from the evaporator of heating, ventilation, and air conditioning (HVAC), senses the coolant temperature of the engine system, V-ECU outputting a pumping start command when the detected coolant temperature is above a set temperature, and a water pump which is operated when a pumping start command is input from the V-ECU to pump condensed water stored in the storage tank. And a nozzle for spraying the pumped condensate in the form of a spray in front of a cooling module to prevent overheating of the engine.

Preferably, the method further comprises a drain hose installed on an upper portion of the water tank so that the condensed water may drain when an overflow occurs.

The present invention stores the condensate generated in the air exchanging heat with the evaporator in a heat exchange (Hating, Ventilation, and Air Conditioning) system and pumps when there is a risk of overheating (pumping) the cooler through the nozzle It can be sprayed to the front to protect the engine.

In addition, in order to prevent overheating of the engine by adding a water dispensing device to the existing cooling module, in order to eliminate the hassle of frequently filling the water, condensate generated while the indoor air of the HVAC device is cooled By allowing storage and supply of water, the user can use the equipment without the inconvenience of having to supply the water directly.

Furthermore, in the device that sprays water in front of the cooling module, the condensed water generated during HVAC operation is stored and used to eliminate user's hassle to always fill the water. By reusing the discarded energy, it is possible to reduce the fan or reduce the size of the cooling module, thereby reducing the cost, reducing the noise and increasing the cooling performance.

And, because water generated by condensation is used, energy can be reused, and since there is no foreign matter in the water, the nozzle can be kept from being clogged or contaminated by foreign matter in the water.

In addition, by further improving the cooling performance by using the latent heat of evaporation of water, it is possible to lower the high rotational speed of the fan or to use a small fan and to use the engine's spare power generated in the work. The fuel efficiency can be increased.

In addition, the present invention can be applied to a vehicle, a commercial vehicle, a construction machine using a cooling module (cooling module) using an engine and a fan driving method, and using HVAC.
