High pressure resistant heat exchanger

Technical Field

The utility model belongs to the technical field of the heat transfer technique and specifically relates to a high withstand voltage heat exchanger with multithread way is related to.

Background

The heat exchanger mainly comprises two collecting pipes, flat pipes communicated with the two collecting pipes and fins arranged between the flat pipes, wherein the flat pipes are provided with high pressure resistance for heat exchange media to pass through.

The working principle is as follows: the heat exchange medium enters the collecting pipe through the inlet end of the collecting pipe, then enters the flat pipe through the collecting pipe, and exchanges heat with the outside air in the flowing process of the flat pipe, so that refrigeration or heating is realized.

At present, flat pipe distribution is few in the heat exchanger of wide application, and heat transfer medium concentrates the distribution in flat pipe, when medium flow is too big, causes intraductal pressure too high easily, simultaneously, the relative pressure manifold axial of flat pipe in the traditional heat exchanger sets up perpendicularly for it is little with the flow area of outside air, and heat transfer area is less relatively, and then influences the heat transfer effect.

Therefore, there is a need for improvement of the prior art to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving the technical problem in the correlation technique to a certain extent. Therefore, an object of the utility model is to provide a high withstand voltage heat exchanger optimizes flat tub of overall arrangement, can increase heat transfer medium at the intraductal heat transfer area in limit, increases the heat transfer effect, improves the pressure resistance.

The technical scheme of the utility model as follows:

the utility model provides a high withstand voltage heat exchanger, includes two pressure manifold, flat pipe, feed liquor pipe and drain pipe respectively with two pressure manifold intercommunication, flat pipe sets up along pressure manifold axial level, and flat pipe is provided with the multiunit along the pressure manifold is radial.

Further, feed liquor pipe and drain pipe set up perpendicularly at the pressure manifold body for flat pipe.

Furthermore, one side opposite to the collecting pipe is provided with a plurality of flat pipe holes for flat pipe connection, and the joint is welded, sealed and fixed.

Furthermore, the flat pipes connect the collecting pipes on two sides through the flat pipe holes.

Furthermore, the diameter of the collecting pipe is larger than the total height of the three layers of flat pipe holes.

Furthermore, three rows of flat pipe holes are horizontally arranged along the axial direction of the collecting pipe and are distributed in parallel in the radial direction.

Furthermore, flat pipe holes staggered at intervals are arranged, so that three rows of flat pipes are distributed at intervals in a staggered manner, and meanwhile, corresponding flat pipes in the same row are arranged in a staggered manner.

Furthermore, three rows of flat tube holes are arranged in one group, and each group is arranged in a step mode, so that the three rows of flat tubes are distributed in a step mode in a staggered mode.

The utility model provides a beneficial effect: the flat pipes are distributed in multiple groups horizontally relative to the collecting pipe body, so that the number of the flat pipes in the collecting pipe is increased to a certain extent, and heat exchange media can be distributed in the flat pipes relatively less, so that the phenomenon that the pressure in the pipes is high due to high medium flow is avoided, the pressure resistance of the heat exchanger is improved, meanwhile, the heat exchange area is increased, and further, the heat exchange efficiency is increased; through flat pipe dislocation or cascaded setting, increase and with air area of contact, improve the vortex effect.
