Abstract

The utility model discloses a heat exchanger which mainly solves the problem that an existing heat exchanger frequently causes blockage and leakage. The heat exchanger comprises a sealed cooling medium box body, a heating medium coil used for conducting heat exchange is arranged in the cooling medium box body, a cooling medium inlet, a cooling medium outlet, a heating medium inlet and a heating medium outlet are formed in the cooling medium box body, wherein the cooling medium inlet and the cooling medium outlet are directly communicated with the cooling medium box body, and the heating medium inlet and the heating medium outlet are directly communicated with the heating medium coil respectively. According to the heat exchanger, due to the fact that the form of the coil is adopted in sealed space for heat exchange, the heat conducting area is greatly increased. Meanwhile, a partition board and connection holes in different positions of the partition board are further added, time for heat exchange of the cooling medium and the heating medium is effectively prolonged, and heat exchange efficiency is further improved.

Description

Heat exchanger

Technical field

The utility model relates to a kind of heat exchanger.

Background technology

The shortcoming that existing similar heat-exchangers of the plate type ubiquity voltage endurance capability is low, runner is narrow, often results in blockage and leaks, and especially in pitch industry, processes maintenance very difficult, has a strong impact on construction quality and progress.

Summary of the invention

The utility model provides a kind of heat exchanger, has mainly solved the problem that existing heat exchanger often results in blockage and leaks.

Concrete technical solution of the present utility model is as follows:

This heat exchanger comprises the cold medium casing of sealing, in cold medium casing, be provided with for carrying out the thermal medium coil pipe of heat exchange, on cold medium casing, be provided with cold medium import, cold media outlet, thermal medium import and thermal medium outlet, wherein cold medium import and cold media outlet are directly communicated with cold medium casing, and thermal medium import and thermal medium outlet are all directly communicated with thermal medium coil pipe.

In above-mentioned cold medium casing, be provided with at least one for the dividing plate of fixed support thermal medium coil pipe, on described dividing plate, be provided with the connecting hole that adjacent two the cold medium casing inner spaces of cutting apart are communicated with.

In above-mentioned cold medium casing, be provided with two for the dividing plate of fixed support thermal medium coil pipe, the connecting hole of one of them dividing plate is arranged on dividing plate bottom, and the connecting hole of another dividing plate is arranged on dividing plate top.

Above-mentioned thermal medium import, thermal medium outlet, cold medium import and cold media outlet are arranged on the wall of cold medium casing the same side, and wherein thermal medium import and cold media outlet are arranged at top side wall, and thermal medium outlet and cold medium import are arranged at sidewall bottom.

The utility model has the advantage of:

The heat exchanger that the utility model provides, owing to having adopted the form of coil pipe to carry out heat exchange in confined space, has greatly improved heat transfer area; Meanwhile, the utility model has also been set up dividing plate and has been arranged on the connecting hole of dividing plate diverse location, has effectively extended the time of cold and hot medium heat exchange, and then has improved the efficiency of heat exchange.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Accompanying drawing is detailed as follows:

The import of 1-thermal medium; The cold media outlet of 2-; 3-hot medium pipeline; The cold medium casing of 4-; 5-holder; The cold medium import of 6-; The outlet of 7-thermal medium; 8-connecting hole.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail, as shown in Figure 1:

This heat exchanger comprises the cold medium casing of sealing, in cold medium casing, be provided with for carrying out the thermal medium coil pipe of heat exchange, on cold medium casing, be provided with cold medium import, cold media outlet, thermal medium import and thermal medium outlet, wherein cold medium import and cold media outlet are directly communicated with cold medium casing, thermal medium import and thermal medium outlet are all directly communicated with thermal medium coil pipe, thermal medium flows in thermal medium coil pipe through thermal medium import, finally by thermal medium outlet, flow out, because cold medium directly contacts with thermal medium coil pipe, so contact area is large, and heat exchange efficiency is high.Generally, thermal medium import, thermal medium outlet, cold medium import and cold media outlet are arranged on the wall of cold medium casing the same side, wherein thermal medium import and cold media outlet are arranged at top side wall, and thermal medium outlet and cold medium import are arranged at sidewall bottom.

In cold medium casing, be provided with at least one for the dividing plate of fixed support thermal medium coil pipe, on described dividing plate, be provided with the connecting hole that adjacent two the cold medium casing inner spaces of cutting apart are communicated with; Generally, in cold medium casing, be provided with two for the dividing plate of fixed support thermal medium coil pipe, the connecting hole of one of them dividing plate is arranged on dividing plate bottom, the connecting hole of another dividing plate is arranged on dividing plate top, the unidirectional longer route of the mobile formation of cold like this medium in cold medium casing, has improved heat exchange efficiency.

The external side of cold medium box is also provided with the holder for being fixed.
