Abstract
A kind of Double-tube-pass heat exchanger of heat shock resistance stress, comprise core body and lower core body, between upper core body and lower core body, right-hand member junction is integrally welded, and right-hand member welds right end socket between upper core body with lower core body, the left end of upper core body welds the first left end socket, and the first left end socket arranges inlet, and the left end of lower core body welds the second left end socket, second left end socket arranges liquid outlet, and the junction of the first left end socket and the second left end socket has been bolted support.The utility model compact conformation, rationally, operation is with simple for production, securing member is adopted to lock in the left end junction of upper core body and lower core body, and right-hand member adopts the design be welded to connect, the left side maximum in the temperature difference, thermal stress is the highest, replaces common integral structure by the split-type structural that can stretch, effectively eliminate the generation of thermal stress, avoid the weld of core body and end socket to produce the phenomenon of splitting due to thermal stress, thus ensure that the functional reliability of heat exchanger, increase the service life.
Description
Technical field
The utility model relates to technical field of heat exchangers, especially a kind of Double-tube-pass heat exchanger of heat shock resistance stress.
Background technology
Heat exchanger, also known as heat exchanger, passes to the device of another kind of heat-carrying agent from a kind of heat-carrying agent by heat.In industrial processes, usually need to carry out heating or cooling, i.e. the transmission of heat.When a kind of fluid and one other fluid carry out heat exchange and do not allow to mix, just requiring to carry out in recuperative heat exchanger, be applied to the industries such as chemical industry, oil, power, food. the Main Function of heat exchanger is thermal energy exchange between cold fluid and hot fluid.
Double-tube-pass heat exchanger of the prior art, connect by welding between upper and lower core body or be machined directly to entirety, when heat exchanger internal circulation high temperature heat transferring medium, core material temperature near import is high, core material temperature near outlet is low, cause dilatancy inconsistent, thus generation thermal stress, at high temperature, low temperature core body is maximum near the junction temperature difference of entrance end, thermal stress is also the most obvious, during the actual use of ordinary heat exchanger, because thermal stress is herein large, the inefficacy product cracked that ruptures accounts for significant proportion, especially large-scale Double-tube-pass heat exchanger (general more than 55kw) product lost efficacy at most herein.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, a kind of Double-tube-pass heat exchanger of heat shock resistance stress rational in infrastructure is provided, thus eliminate the generation of thermal stress, effectively prevent the weld of core body and end socket from producing the phenomenon of splitting, ensure the functional reliability of heat exchanger.
The technical scheme that the utility model adopts is as follows:
A kind of Double-tube-pass heat exchanger of heat shock resistance stress, comprise core body and lower core body, between described upper core body and lower core body, right-hand member junction is integrally welded, and right-hand member welds right end socket between upper core body with lower core body, the left end of described upper core body welds the first left end socket, and described first left end socket arranges inlet, and the left end of described lower core body welds the second left end socket, described second left end socket arranges liquid outlet, and the junction of described first left end socket and the second left end socket has been bolted support.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, rationally, operation is with simple for production, securing member is adopted to lock in the left end junction of upper core body and lower core body, and right-hand member adopts the design be welded to connect, the left side maximum in the temperature difference, thermal stress is the highest, replaces common integral structure by the split-type structural that can stretch, effectively eliminate the generation of thermal stress, avoid the weld of core body and end socket to produce the phenomenon of splitting due to thermal stress, thus ensure that the functional reliability of heat exchanger, increase the service life.

Fig. 2 is the side view of Fig. 1.
Wherein: 1, inlet; 2, the first left end socket; 3, support; 4, bolt; 5, the second left end socket; 6, liquid outlet; 7, upper core body; 8, lower core body; 9, right end socket.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As depicted in figs. 1 and 2, the Double-tube-pass heat exchanger of the heat shock resistance stress of the present embodiment, comprise core body 7 and lower core body 8, between upper core body 7 and lower core body 8, right-hand member junction is integrally welded, and right-hand member welds right end socket 9 between upper core body 7 with lower core body 8, the left end of upper core body 7 welds the first left end socket 2, first left end socket 2 arranges inlet 1, the left end of lower core body 8 welds the second left end socket 5, second left end socket 5 arranges liquid outlet 6, and the junction of the first left end socket 2 and the second left end socket 5 is connected with support 3 by bolt 4.
The utility model does not weld at the left end of upper and lower core body junction, welds at right-hand member, makes heat exchanger in heat transfer process, eliminate the generation of thermal stress, ensures dependability, increases the service life.
In actual installation process, first the first left end socket 2 is welded on the left end of upper core body 7, the second left end socket 5 is welded on the left end of lower core body 8, then in the right-hand member welding of the junction of upper and lower core body, finally welds right end socket 9.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
