Abstract

The utility model discloses a compound heat exchanger which is mainly composed of an exchange pipe (1), a fixing plate (2) and heat absorption fins (3), wherein the exchange pipe (1) is arranged on the fixing plate (2) in a multilayer staggered structure, and the heat absorption fins (3) are densely arranged outside the exchange pipe (1). The utility model has the advantages of unique conception, high heat efficiency which can reach 92%, small size, light weight, strong bearing force and low cost, and can instantly and sufficiently heat exchanged medium (water). The utility model can be widely popularized and used.

Description

The combined type heat exchanger

The utility model belongs to technical field of heat exchange, and what relate generally to is a kind of combined type heat exchanger.

Heat exchanger is parts the most key in heating system and the hot-water heating system, and it just is directly connected to the result of use of heating or hot water heating to the utilization of heat energy.At present, the exchange pipe of heat exchanger employing both at home and abroad is essentially pipe, and is vertical coiling structure mostly.Because the heat exchanger heating surface of this structure is few, thereby the exchange media (water) in the inflow heat exchanger is difficult to fully heating in moment, and the heat energy utilization rate is lower.For improving its thermal efficiency, the measure of taking at present is the volume that increases heat exchanger, improves exchange media (water) transient heating ability to increase heating surface.But the drawback of bringing thus is: the heat exchanger volume is big, Heavy Weight, consumptive material are many, production cost occupies high-leveled and difficult time.Simultaneously, exchange media (water) flow velocity is slow, easily forms incrustation scale in tube wall, and then has influenced the result of use and the service life of heat exchanger.

The purpose of this utility model promptly produces thus, but proposes a kind of structural design uniqueness, heat energy utilization rate height, volume is little, in light weight, the cost cost is low, bearing capacity strong moment fully adds heat exchange medium (water) combined type heat exchanger.

For achieving the above object, the utility model is achieved through the following technical solutions: it is made up of exchange pipe, left and right fixed head, heat absorption fin, the exchange pipe is multi-layer intercrossed arrangement architecture and is arranged on the left and right fixed head, is densely covered with the heat absorption fin outside the exchange pipe.

This practical being skillfully constructed, the structure uniqueness.Because heat-exchange tube is multi-layer intercrossed arrangement architecture, thereby has increased the heating surface of heat-exchange tube, and the thermal efficiency can be improved more than 30%.And heat-exchange tube also is densely covered with the heat absorption fin outward, and by the conduction of heat absorption fin, but moment is to fully heating of exchange media (water).Because the raising of the thermal efficiency, the volume of heat exchanger can greatly reduce, thereby has saved material, has reduced manufacturing cost.Inside and outsidely compare around pipe straight-line interchanger with traditional, its cost can reduce by 50%.And heat-exchange tube is a flat, has accelerated the flow velocity of exchange media (water), makes it less scaling in tube wall, has improved the result of use and the service life of heat exchanger.

The utility model accompanying drawing is a structural representation.

In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:

As shown in the figure: present embodiment is made up of exchange pipe 1, fixed head 2 and heat absorption fin 3.Exchange pipe 1 can be traditional circle, also can be flat, and present embodiment is a flat, and purpose is to accelerate the flow velocity of exchange media (water), is difficult for fouling in the exchange tube wall.Exchange pipe 1 is multilayer (the best is three layers) staggered structure and is arranged on the left and right fixed head 2, and its entrance end is respectively equipped with circular joint 4.Outside exchange pipe 1, be densely covered with heat absorption fin 3.Present embodiment in use, staggered exchange pipe 1 can comprehensively be heated, and adds the conduction of heat absorption fin 3, can moment exchange media (water) be heated.
