Abstract

The utility model discloses a ring cavity solar energy heat exchanger. The ring cavity solar energy heat exchanger comprises a heat collector (5), a shell body (1) and a heat exchanger (2) arranged in the shell body (1), wherein the heat collector (5) is arranged on the lower portion of the shell body (1), the shell body (1) is a cylindrical cavity provided with an insulating layer and filled with heat-conducting medium, an inner core (3) is arranged on the portion, over the central axis, in the shell body, and the inner core (3) and an inner cavity of the shell body (1) form a ring cavity (4). At least one heat exchanger (2) is arranged in the ring cavity (4) over the inner core (3). The ring cavity solar energy heat exchanger has the advantages that the structure is simple, the production is easy, the promotion and application are benefited, the heat exchanger in a tubular structure is arranged in the ring cavity over the inner core, and therefore the heat exchange efficiency is high.

Description

A kind of annular chamber solar heat exchanger

Technical field

The utility model relates to a kind of annular chamber solar heat exchanger, mainly is to utilize solar energy to realize the device of heat exchange by the heat-conducting medium heating heat exchanger inner fluid that is rapidly heated in the ring cavity structure.

Background technology

Existing inner bag arranges the solar energy hot water tank of heat exchanger, can make the fluid of two or more different mediums by simultaneously separately heating, it is flowed in water tank and in the heat exchanger respectively, cooperate solar water heating system, form the circulation of double loop or multiloop, but guiding device and volume are not larger owing to having in water heater or the housing, water after being heated is difficult to form mobile fast in order for the outer wall of heat exchanger, thereby the heat transfer coefficient of heat exchanger is little, heat transfer efficiency is low, cause the fluid programming rate in the heat exchanger slow, affected the heat transference efficiency of whole solar heater, the solar energy hot water tank (patent No. ZL20092002 of utility model ring cavity structure

151.1), a kind of annular chamber solution has been proposed, can be with solar heat by the heat-conducting medium heating heat exchanger that is rapidly heated in the annular chamber mechanism, but heat-conducting medium in uphill process with the heat transferred heat exchanger, and heat exchanger is not heated in reflux course, lowered the temperature on the contrary, therefore, its heat transfer effect still is not ideal.

The utility model content

In order to solve the problems of the prior art, the purpose of this utility model provides a kind of simple in structure, annular chamber solar heat exchanger that heat exchange efficiency is high.

For achieving the above object, the technological means that the utility model adopts is: a kind of annular chamber solar heat exchanger, comprise heat collector, housing and be installed in the interior heat exchanger of housing, described heat collector is installed in lower housing portion, described housing is with heat-insulation layer, is filled with the cylindrical cavity of heat-conducting medium, be provided with inner core more than the axis in the housing, inner core and housing inner chamber form annular chamber; Described heat exchanger arranges one at least, is installed in the annular chamber of inner core top.

Further, described inner core is tubulose or polygonal cylinder.

Further, described heat exchanger adopts tubular cylinder or tubulose gengon or finned tubular cylinder or finned tubulose gengon.

The beneficial effects of the utility model are: mounting structure is simpler, and it is easier to produce, and is conducive to promote the use of; Adopt the heat exchanger of tubular structure to be positioned at annular chamber, the top of inner core makes heat exchange efficiency higher.

Description of drawings

Below in conjunction with accompanying drawing the technical solution of the utility model is described.

Fig. 1 is top cross-sectional view of the present utility model;

Fig. 2 is left view of the present utility model.

Among the figure: 1, housing, 2, heat exchanger, 3, inner core, 4, annular chamber, 5, heat collector.

The specific embodiment

A kind of annular chamber solar heat exchanger as shown in Figure 1, 2, comprise heat collector 5, housing 1 and be installed in heat exchanger 2 in the housing 1, described heat collector 5 is installed in housing 1 bottom, described housing 1 for heat-insulation layer, be filled with the cylindrical cavity of heat-conducting medium, housing is provided with inner core 3 more than the 1 interior axis, and inner core 3 forms annular chamber 4 with housing 1 inner chamber; Described heat exchanger 2 arranges one at least, is installed in the annular chamber 4 of inner core 3 tops.

Further, described inner core 3 is tubulose or polygonal cylinder.

Further, described heat exchanger 2 adopts tubular cylinder or tubulose gengon or finned tubular cylinder or finned tubulose gengon.

Inner chamber and inner core 3 combinations with heat-insulation layer housing 1, formation can be filled with the liquid of heat-conducting medium, and can play annular chamber 4 structures of guide functions, namely form the guiding device in the housing, be arranged on the heat exchanger 2 of inner core 3 tops in the annular chamber 4, adopt tubular heat exchanger, its operation principle: heat collector 5 receives solar energy and transforms the heat-conducting medium intensification that makes in the annular chamber 4, form flowing in order of hot fluid along annular chamber 4, with the heat exchanger 2 in the heat transferred annular chamber 4, heat exchanger 2 interior fluid such as water as heat-conducting medium, wet goods is accepted to heat up behind the heat, delivers to connected external container and stores or directly used.

Embodiment of the present utility model explains, and is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the utility model discloses, and can expect easily changing or replacing, and all should be encompassed within the protection domain of the present utility model.
