Tube nest soaking type cooling system

Abstract

The invention discloses a tube nest soaking type heat exchanger which comprises a tube nest soaking type condenser, a cooling circulating pump, a sprayer, a water distributor, a fan, a cooling packinglayer and a cooling water tank. The tube soaking type condenser is soaked in cooling water in the cooling water tank, the water distributor and the cooling circulating pump are arranged at the bottomin the cooling water tank, the sprayer is located above the cooling packing layer and sprays cooling water to the surface of the cooling packing layer, a cooling filler is arranged between the sprayer and the tube nest soaking type condenser, and the fan is arranged above the sprayer and is used for discharging latent heat of vaporization of vaporized saturated water vapor in the cooling packinglayer and the cooling water tank into outdoor atmosphere. The heat exchanger has the advantages of being capable of reducing the flow speed of cooling water, prolonging the heat exchange time of the cooling water and a refrigerant, improving the water outlet temperature of the cooling water, increasing the evaporative cooling heat dissipation area, improving the latent heat of vaporization of thecooling water and being easy to clean, and the purposes of reducing the temperature of the refrigerant and improving the cooling heat exchange efficiency of the cooling pipe are achieved.

Description

technical field [0001] The invention relates to the field of air-conditioning equipment, in particular to a tubular tube immersion cooling system. Background technique [0002] In the field of refrigeration and air conditioning, shell-and-tube condensers or sleeve-pipe condensers are commonly used. They are characterized by small heat transfer volume, high heat transfer efficiency, mature technology, and low cost. Therefore, they are widely used in air-conditioning hosts as mainstream accessories. But whether it is a shell-and-tube condenser or a sleeve-and-tube condenser, there are the following problems: 1. The scale is not easy to clean: since the heat exchange between the refrigerant and the brine (water) is completed in the closed shell tube, the scale inside the shell tube The shell-and-tube condenser must be disassembled and cleaned when it is shut down. The maintenance is difficult, the workload is heavy, and frequent maintenance affects production. 2. Under a cert...

Problems solved by technology

But whether it is a shell-and-tube condenser or a sleeve-and-tube condenser, there are the following problems: 1. The scale is not easy to clean: since the heat exchange between the refrigerant and the brine (water) is completed in the closed shell tube, the scale inside the shell tube The shell and tube condenser must be disassembled and cleaned after shutting down

3. The power consumption of the cooling pump is high: due to the small overall volume of the shell-and-tube condenser or the sleeve-tube condenser, and the limited heat exchange area in the shell, if the heat exchange capacity is increased, the heat exchange volume flowing through the surface of the heat exchange body in the tube must be increased per unit time. Cooling water circulation volume, which in turn increases the flow rate in the cooling water pipe

Since the friction in the tube is proportional to the square of the flow rate, the increase in cycle power requires a higher power cooling pump, which increases power consumption
