Heat exchanger with open-type, communicated and heat-absorbing cooling water pipe

Abstract

The invention discloses a heat exchanger device with a open-type, communicated and heat-absorbing cooling water pipe, which can be used not only for heating and heat radiation, but also for replacing bathing hot water. The heat exchanger has a compact structure and is simple in manufacturing technique; water storage communicated flow splitting chambers are respectively arranged in sealing heads at two ends of each heating pipe; the inner chambers of the heating pipes and the water storage communicated flow-dividing chambers are isolated by welding separating walls; at least one cooling water pipe penetrates each heating pipe; mouths of two ends of each cooling water pipe are arranged on the corresponding separating walls and communicated with the water storage communicated flow-dividing chambers; the mouths of two ends of each cooling water pipe are communicated with the water storage communicated flow-dividing chambers in an open manner, so as to bring convenience for filling acid liquor to clean deposited dirt in the cooling water pipes; the cooling water pipes can be used for water storage and heat absorption, and the effective heat source can be fully utilized; dividing walls can quickly absorb heat; the heat is transferred in a stepped manner to increase the heat-absorbing area; and the cooling water, which is stored in the water storage communicated flow-dividing chambers, is used for heat absorption. According to the invention, as the water is stored in the device, the process length of the cold fluid is increased, the heat exchange time is prolonged, the heat loss is reduced, the heat exchange efficiency is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a heat exchanger for household heating, in particular to a heat-absorbing heat exchanger connected with open cold water pipes. Background technique [0002] At present, the home heating method has changed from the original wall-mounted type to floor heating, that is, a heating pipe network with a diameter of 20mm and a pipe spacing of 200mm is laid under the floor, and the floor dissipates heat in a large area, and the temperature of the heating water is reduced from above 70 degrees to Only 45 degrees of heating is required, and the indoor temperature can reach a temperature of more than 20 degrees. The existing heat exchanger technology is no longer suitable for the current low water temperature requirements for heating, not only the design is unreasonable but also there are obvious deficiencies: the cold water heat-absorbing pipe in the existing heat exchanger is closed with a single pipe in the cavity of the heat supply pip...

Problems solved by technology

[0005] In order to overcome the small heat transfer area of ​​the existing heat exchanger, low heat transfer efficiency, poor heat absorption effect of the single-channel closed reciprocating coil of the cold water pipe, easy fouling and blockage in the cold water pipe, can not be cleaned by pouring acid solution, short service life, and difficult to manufacture, etc. Defects, the present invention provides a heat-absorbing heat exchanger made of the same metal material with open mouths at both ends of the cold water pipe. The heat exchanger has a compact structure and a simple manufacturing process. There are water storage and communication diversion chambers respectively, and the inner cavity of the heating pipe and the water storage and communication diversion chamber are separated by welding partitions; at least one cold water pipe is passed through the heating pipe, and the openings at both ends of the cold water pipe are welded on the partition And communicate with the water storage Unicom shunt chamber; the openings at both ends of the cold water pipe are connected with the water storage Unicom shunt chamber, which is convenient for pouring acid solution to clean the dirt deposited in the cold water pipe; the cold water pipe stores water and absorbs heat, which can make full use of effective heat sources , multi-partition walls quickly absorb heat, and the heat is transferred in steps, which increases the heat-absorbing area; cold water is stored in the water storage and diversion chamber to absorb heat, and the internal water storage increases the flow length of the cold fluid, prolongs the heat exchange time, and reduces heat loss. , improve heat transfer efficiency and reduce production cost
