A heat exchange device using condensed water

Abstract

The invention discloses a heat exchange device utilizing condensate water. The heat exchange device comprises a permeable membrane set, heat exchange fins, supporting battens, a condensate water incoming pipe and a condensate water outgoing pipe; an IPM module and the heat exchange fins in the area of the IPM module are completely sealed by the permeable membrane set; condensate water generated during the operation of an air conditioner enters the permeable membrane set through the condensate water incoming pipe; the permeable membrane set is made of a negative-pressure permeable membrane; andafter the condensate water is evaporated into water vapor in the permeable membrane set, the water vapor permeates to a low-pressure side outside the membrane from a high-pressure side inside the membrane to take away heat generated during the work of the IPM module; after the inner side of the membrane absorbs the heat of the high-temperature IPM module, and the temperature of the inner side ofthe membrane rises, saturation pressure difference caused by inside and outside temperature difference positively promotes the condensed water in the membrane to permeate out of the membrane; the evaporation and heat absorption of the condensed water of the air conditioner are utilized to dissipate the heat of the high-temperature IPM module; the condensed water of the outdoor unit of the air conditioner is evaporated through the permeation effect of the permeable membrane set; and evaporation latent heat is utilized to dissipate the heat of a heat exchange element. The heat exchange device issimple in structure and free of extra power consumption.

Description

Technical field [0001] The present invention belongs to the field of air conditioning technology, to design an apparatus and method for enhanced heat transfer using condensed water. Background technique [0002] Inverter air conditioner outdoor unit is located inside the intelligent power module (referred to as IPM) the output power of the IGBT element, and a plurality of driving circuit protection circuitry integrated within the same module, is a highly integrated smart power IC. IPM module for its high reliability, ease of use has won a growing market, especially for the various drive inverters and inverter motor is frequency control, servo drives a frequency appliances ideal for power electronic devices. [0003] However, the IPM module issues a larger heat during operation, the surface temperature of the device is often higher than 80 ℃, summer operating conditions the surface temperature of the refrigerant even at 100 ℃. If there is no external cold source to be controlled w...

Problems solved by technology

[0003] However, the IPM module generates a lot of heat during work, and the surface temperature of the device is often higher than 80°C, and the surface temperature can even reach 100°C in summer when it is operating under cooling conditions

If there is no external cooling source to control it within a reasonable temperature range, the performance of the IPM module may be affected by high temperature, causing the compressor to fail to reach the operating power; in severe cases, the IPM module may even be burned and the air conditioner will be shut down
