Semi-volume type water heater

Technical Field

The invention belongs to the technical field of heat exchangers, and particularly relates to a semi-volume water heater.

Background

The semi-positive displacement heat exchanger is a device which utilizes a heat exchange element to heat cold water in a shell to the service temperature of domestic water and then directly outputs the cold water for use, is used as civil or industrial equipment, is widely applied to occasions such as hotels, restaurants, schools, laundries, ships and the like, and is used as an important component of a hot water supply system.

At present, the existing heat exchanger is usually heated by water entering from a water inlet through a heating pipe, the heated water flows out through a water outlet pipe, the water outlet pipe is arranged in a tank body, and a pipe orifice is arranged downwards. Under this kind of structure, hot water is difficult to reach jar body bottom for the water of bottom is after a period, and cooling water is cooled down, and volume utilization is low, and bacterial growing problem, and hot water distributes insufficiently evenly.

Disclosure of Invention

The invention provides a semi-volume type water heater with high volume utilization rate in order to overcome the defects of the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: a semi-volume water heater comprises a tank body, an outlet arranged on the tank body, a shell arranged in the tank body, a heat exchange tube bundle arranged in the shell, a water inlet and a water outlet arranged on the shell; the bottom of the tank body is provided with an inlet which is communicated with the water outlet through a connecting pipe; the inlet is provided with a flow guiding and stabilizing device for realizing the stable delivery of water flow into the tank body; the heat exchange tube bundle comprises a plurality of baffle plates and heat exchange tubes arranged on the baffle plates; the heat exchange tube has a corrugated section.

Through the arrangement of the connecting pipe, when hot water flows out of the water outlet, enters the connecting pipe, and then flows out of the inlet, the water enters the tank body from the bottommost position of the tank body and is conveyed upwards, the hot water is ensured to be completely stored in the tank body, no cold-temperature water stagnation area is ensured to be arranged in the tank body, higher heat exchange efficiency is achieved, lower energy consumption is achieved, meanwhile, when no cold water is detained, the utilization rate of the interior of the tank body reaches one hundred percent, meanwhile, the problem that dead water stays in the tank body is solved, the bacteria are prevented from breeding, through the arrangement of the flow guide stabilizer, the hot water flows out of the inlet, finally, the flow guide stabilizer is used for spraying outwards, the flow guide stabilizer is used for realizing that water flow is conveyed into the tank body in a stable state, a water distributor purchased from the market can be adopted, and the hot water can flow into the bottom of the tank body at a gentle flow rate under the action of the flow guide stabilizer, and can be in jar body bottom at the furthest disperse for hot water distributes more evenly, further avoids jar body bottom the condition that the difference in temperature appears, improves volume utilization ratio, through the setting of ripple section, has increased the area of contact with water, and water flows according to the shape orbit of ripple section simultaneously, makes water produce the flow of height fluctuation, has started the effect of rocking to water, thereby reaches the heating effect more.

Further, the connecting pipe can be arranged outside the tank body; make when assembling equipment, more convenient installs equipment, reduced artifical input cost, break down when equipment, when needing to maintain, can directly maintain equipment outside again, more convenient during the maintenance is convenient.
