Description

Plate heat exchanger that leakproofness is strong

Technical Field

The utility model relates to a heat exchanger technical field specifically is a plate heat exchanger that leakproofness is strong.

Background

The plate heat exchanger is a high-efficiency heat exchanger formed by stacking a series of metal sheets with certain corrugated shapes, a channel with a certain shape is formed between various plates, and partial heat is transferred to cold fluid by hot fluid through the plates. The plate heat exchanger is widely applied to many fields with energy conversion processes as a thermal power mechanical device with excellent heat transfer performance. The condition that the seepage can appear in current plate heat exchanger long-time use, can leak the outside inconvenient clearance of heat exchanger. Therefore, a plate heat exchanger with strong sealing performance is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a plate heat exchanger that leakproofness is strong to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a plate heat exchanger that leakproofness is strong, includes front end plate and back end plate, the welding of front end plate trailing flank has the shell, the back end plate leading flank seted up all around with shell assorted recess, through bolt fixed connection between back end plate and the front end plate, install a plurality of heat transfer slab in the shell, both ends communicate respectively about the front end plate left side has cold water inlet and cold water export, both ends communicate respectively about the front end plate right side have hot water export and hot water entry, and adjacent two sets of seal gasket all installs between the heat transfer slab, the through-hole has all been seted up to corresponding cold water inlet, cold water export, hot water export and hot water entrance on heat transfer slab and the sealed gasket.

Preferably, guide rods are welded on the upper side wall and the lower side wall in the shell, and guide grooves matched with the guide rods are formed in the upper side wall and the lower side wall of each heat exchange plate.

Preferably, the rubber strip is bonded to the outer edge of the groove.

Preferably, the flow channels of two adjacent groups of heat exchange plates are opposite.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses an install the shell between the heat transfer slab outside, front end plate and rear end plate, play sealed effect, prevent that the medium between the heat transfer slab from oozing the heat exchanger outside, the junction of rear end plate and shell is seted up flutedly to the recess outer fringe bonds and has the rubber strip, makes between shell and the rear end plate be connected inseparabler, avoids the weeping, can dismantle between shell and the rear end plate, and the convenience is maintained its inside.
