Abstract
A tube heat exchanger, belonging to the heat exchanging devices, comprises a canister (1), tube sheets (2), and tubes (3). The tubes (3) are arranged inside the canister (1) in longitudinal direction, the tube sheets (2) are arranged at two ends of the canister (1) and tightly welded with the canister (1), and holes corresponding to the tubes (3) are arranged on the tube sheets (2) and tightly welded with the intersection sites of the holes and the tubes (3). A draw plate (4) is arranged inside the canister (1) and fixedly connected with the tubes (3). In the tube heat exchanger provided in the utility model, the draw plate takes fixation action, so that the tubes can not shift, and the installation and welding operations are convenient.
Description
Affiliated technical field
The utility model relates to a kind of heat-exchange device.
Background technology
Can often use heat-exchanger rig in the Chemical Manufacture, especially be many with tubular heat exchanger, tubular heat exchanger is to arrange many heat exchanger tubes in socket, and heat exchanger tube and socket are separate to be two spaces, when different temperatures material flow during, promptly produce heat exchange through socket and tubulation.Because leaking very easily appears in tubulation in the heat exchanger, so just tubulation need be pulled down welded and installed again after the mending-leakage.But when heat exchanger was oversize, the deviation dislocation often appearred in tubulation, made when welding is installed to encounter difficulties.
Summary of the invention
The utility model provides a kind of tubular heat exchanger, and it can be avoided, and deviation appears in tubulation in the heat exchanger, makes the installation convenient welding.
In order to achieve the above object, technical solution adopted in the utility model is:
A kind of tubular heat exchanger comprises tube, card, tubulation, and described tubulation vertically is arranged in the tube, the tube two ends be provided with card, and with the airtight welding of tube, described card is provided with and the corresponding hole of tubulation, and itself and tubulation cross-shaped portion are closely welded, be provided with arm-tie in the described tube.
The above tubular heat exchanger, described arm-tie is fixedlyed connected with tubulation.
The utility model makes tubulation skew can not occur owing to there is arm-tie to play fixation, and is easy to operate when welding is installed.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 be among the utility model Fig. 1 A-A to schematic diagram.
Among the figure: 1. tin; 2. card; 3. tubulation; 4 arm-ties.
The specific embodiment
By accompanying drawing as can be known, the utility model comprises tube 1, card 2, tubulation 3, and described tubulation 3 vertically is arranged in the tube 1, tube 1 two ends are provided with card 2, and with tube 1 airtight welding, on card 2, be provided with and tubulation 3 corresponding holes, and itself and tubulation 3 cross-shaped portions closely welded.Be provided with arm-tie 4 in the described tube 1, and arm-tie 4 is fixedlyed connected with tubulation 3.
Claims (2)
1, a kind of tubular heat exchanger, comprise tube (1), card (2), tubulation (3), it is characterized in that: described tubulation (3) vertically is arranged in the tube (1), tube (1) two ends are provided with card (2), and with the airtight welding of tube (1), described card (2) is provided with and the corresponding hole of tubulation (3), and itself and tubulation (3) cross-shaped portion are closely welded, and is provided with arm-tie (4) in the described tube (1).
2, according to the described tubular heat exchanger of claim 1, it is characterized in that: described arm-tie (4) is fixedlyed connected with tubulation (3).
