Embodiment
One of core of the present invention is to provide a kind of heat exchanger, so as to the number of welds in current heat exchanger is reduced,
There is the risk leaked so as to reduce heat exchanger.
Another core of the present invention, which also resides in, provides a kind of heat transmission equipment with above-mentioned heat exchanger.
In order to make those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Disclosed in this invention heat exchanger, including heat exchanger tube 4, certainly, in order to ensure heat transfer effect, usual heat exchanger tube 4
Outside be also covered with heat exchange fin 3, to increase the heat exchange area of heat exchanger as far as possible, heat exchanger tube 4 at least forms one and changes
Heat passage, each heat exchange path is that one end is connected with heat exchanger inlet tube 1, and the other end is connected with heat exchanger exit pipe 2, and
And each heat exchange path bends disk by a complete heat exchanger tube 4 and sets to be formed.
As shown in Fig. 1 to Fig. 6, the arrow in figure represents the flow direction of heat transferring medium, and heat transferring medium is by heat exchanger inlet tube 1
Into heat exchanger, completed in heat exchanger tube 4 after exchanging heat by 2 outflow heat exchanger of heat exchanger exit pipe.
Since in the heat exchanger disclosed in above-described embodiment, any one heat exchange path is by a complete heat exchange
Pipe 4 bends disk and sets what is formed, has abandoned the form that traditional straight tube adds elbow welding, forms the heat exchanger tube 4 of whole heat exchange path
For integral type heat exchanger tube, without carrying out any welding, this just greatly reduces the quantity of solder joint in whole heat exchanger, so that
Effectively reduce heat exchanger and the risk leaked occur, substantially increase the reliability of heat exchanger work.
It will be appreciated by persons skilled in the art that in a heat exchanger, the heat exchange path that is formed by heat exchanger tube 4 can be with
To be one or more, if when heat exchange path includes multiple heat exchange power can bigger, certainly, if increase heat exchange path
4 length of heat exchanger tube can similarly achieve the purpose that to increase heat exchange power.
Heat exchanger disclosed in the present embodiment, heat exchanger tube 4 specifically forms two heat exchange paths in parallel, such as Fig. 4 to Fig. 6
Shown in, and any one heat exchange path in the two heat exchange paths includes at least one heat exchange layer 43, in Fig. 5 and Fig. 6
