Abstract

The utility model relates to a liquid heat exchanger head belongs to the flowing back structure of the aircraft ring accuse technical field of system, an in particular to liquid heat exchanger. This structure comprises outage (1) and blanking cover (2), and outage (1) and blanking cover (2) is by passing through threaded connection to provide sealed for the head. This structure influences the nothing of installation, use and the product efficiency etc. Of heat exchanger, but in use, maintenance process, the work load in reduction outfield that can be very big, improvement work efficiency.

Description

A kind of liquid heat-exchanger end socket

Technical field

This utility model one liquid heat-exchanger end socket belongs to aircraft environmental control system technical field, particularly to the drainage structure of a kind of liquid heat-exchanger。

Background technology

Common liquid heat-exchanger end socket is as it is shown in figure 1, this kind of end socket is generally adopted the mode of casting or machining, without drainage structure。

End enclosure structure processing is relatively simple, it is easy to batch production。But the end socket place that is in use everlasting forms dead space, in heat exchanger, the impurity of fluid can deposit herein, reduce efficiency of heat exchanger, and outfield is when safeguarding heat exchanger or more switching heat-exchanger intracavity liquid, heat exchanger entirety can only be taken off, liquid in heat exchanger is poured out, significantly increases the workload of flight-line service。

Summary of the invention

The purpose of this utility model is to provide the drainage structure of a kind of liquid heat-exchanger end socket, and this structure can be good at solving the problem such as liquid discharge, heat exchanger cleaning in the flight-line service of liquid heat-exchanger。

Technical solution of the present utility model is: a kind of liquid heat-exchanger end socket, it is characterized in that, arranging a center in the bottom of described liquid heat-exchanger end socket with the cylindrical outage 1 of internal thread through hole, blanking cover 2 is with externally threaded cylindrical structural, blanking cover 2 is inserted into outage 1, and threaded with outage 1, make liquid heat-exchanger end socket seal。

Advantageous Effects: adopt outage 1 and the blanking cover 2 of this kind of version, in the process installed and used, with original structure form indifference, performance without influence on heat exchanger, but it is the reduction of the workload in line maintenance process, whole product can be dismantled by emptying rate of liquid in heat exchanger, facilitate the cleaning of impurity in radiator。Install, dismounting blanking cover does not need special equipment, common inner hexagon spanner, improves work efficiency。

Detailed description of the invention

Below in conjunction with Figure of description, this utility model is described in further detail, refers to Figure of description 2。

This utility model one liquid heat-exchanger end socket, adopt the mode of casting or machining to produce the center cylindrical outage (1) with internal thread through hole in bottom minimum point in the bottom of described liquid heat-exchanger end socket, this outage (1) can have stepped hole。Blanking cover (2) be by machining produce with externally threaded cylindrical structural, it is possible to have interior six square grooves。The screw thread of blanking cover (2) mates with the screw thread of outage (1), and blanking cover (2) is inserted into outage (1), and threadeds with outage (1), makes liquid heat-exchanger end socket seal。

Embodiment 1: do not have the figure of stepped hole, such as Fig. 5。

The blanking cover of embodiment 2: six side's platform, such as Fig. 6。

Claims

1. a liquid heat-exchanger end socket, it is characterized in that, arranging a center in the bottom of described liquid heat-exchanger end socket with the cylindrical outage (1) of internal thread through hole, blanking cover (2) is with externally threaded cylindrical structural, blanking cover (2) is inserted into outage (1), and threaded with outage (1), make liquid heat-exchanger end socket seal。
