Description

The proposed utility model relates to electrical engineering and relates to a nickel-hydrogen storage battery (hereinafter referred to as NVAB), the bearing element of which is a housing, in the openings of which nickel-hydrogen batteries (hereinafter referred to as NVA) are installed.

Nickel-hydrogen storage battery is a chain of series-connected NVA, pressure sensors sensitive to pressure changes inside the battery, characterizing the current electric capacity, and temperature sensors. To improve the resource characteristics of NVAB, it is very important to ensure the required temperature regime during its operation, while it is especially important to maintain the temperature in a relatively narrow range. Ensuring the temperature regime of the NVAB as part of the spacecraft (hereinafter referred to as the SC) is carried out by the thermal control system (hereinafter referred to as the SC) of the SC. It is known that onboard equipment and individual components of spacecraft load spacecraft with heat differently.

Known NVAB (Battery 28NV-70R Technical description and operating instructions ZhTsPI.563533.014TO 2003, sheet 9), the bearing element of which is a housing in the openings of which are installed, connected in series to the NVA. The housing design provides minimal thermal gradients and sufficient thermal conductivity. To remove heat from the NVAB hull as part of the spacecraft, it is envisaged that the lower part of the hull will be mounted to a radiator plate of an external forced cooling system.

The disadvantage of the analogue is the inertia of the STR, a large thermal resistance between the heat source - the electrode block of the battery and the radiator stove with an external forced cooling system and the influence of heat generation of other components and blocks of the spacecraft.

Signs of an analogue common with the proposed NVAB are as follows:

- NVAB consists of a housing in the openings of which are installed in series connected NVA;

- to remove heat, NVAB is installed on the STR-KA radiator stove.

Known NVAB (Battery 40NV-70 Technical description and operating instructions ZhTsPI.563533.012-01TO 2004, sheet 11) adopted as a prototype, the bearing element of which is a housing, in the openings of which are installed, connected in series to the NVA. The housing design provides minimal thermal gradients and sufficient thermal conductivity. To remove heat, cooling channels of the thermal control system of the entire spacecraft are installed on the side faces of the hull as part of the spacecraft.

The disadvantage of the prototype is that the STR is constructed in such a way that takes into account the heat dissipation of other nodes and blocks of the spacecraft, while it is difficult to ensure a narrow range of temperature maintenance NVAB.

The features common to the proposed NVAB and prototype are as follows:

- NVAB consists of a housing, in the openings of which are installed series-connected NVA;

- to remove heat, cooling paths of the temperature control system are installed on the side faces of the housing.

The technical result achieved in the proposed NVAB is to maintain a narrow temperature range of the NVAB on the spacecraft and its higher resource and power characteristics.

This is achieved by the fact that in the NVAB, which consists of a housing, in the openings of which are connected serially connected nickel-hydrogen batteries, and which is equipped with a thermal control system located on the side faces of the housing, the thermal control system is autonomous and contains a heat pipe that is directly installed on lateral faces of the hull, and, in addition, heat-insulating gaskets are provided for attaching the NVAB to the spacecraft.

The NVAB is attached to the spacecraft through heat-insulating gaskets, which minimizes the thermal effect of the onboard equipment and other components of the spacecraft, and the heat pipe installed directly on the NVAB body, which is an element of the autonomous STR, maintains a temperature in a relatively narrow range, and, in accordance with this, NVAB has higher resource and power characteristics.

Distinctive features that determine the relevance of the proposed NSAI to the criterion of “novelty” are as follows:

- the NVAB housing is equipped with heat-insulating gaskets;

- NVAB is equipped with an autonomous system STP, and which contains a heat pipe mounted directly on the side faces of the housing NVAB

The design of the proposed NVAB is depicted in figure 1 and figure 2.

The proposed NVAB (figure 1, 2) consists of the following parts: housing 1, connected in series to the NVA 2, the heat pipe 3, the contour heat pipe 4 and the radiation panel 5. For fastening the NVAB to the spacecraft, heat-insulating pads 6 are provided.

An example of a specific implementation of the proposed NVAB depicted in figure 2.

Nickel-hydrogen storage battery NVAB consists of the following parts: housing 1, connected in series NVA 2, axial heat pipe 3, loop heat pipe 4 connected to the radiation panel 5.

Case 1 is designed to install the NVA 2 in it and combine all the components in it into a single whole, as well as to ensure heat transfer from the NVA 2 during the charge / discharge of the NVAB.

An axial heat pipe 3, mounted on each side of the housing 1, with a contour heat pipe 4 and a radiation panel 5 constitute an autonomous system of temperature control NVAB.

The NVAB is attached to the spacecraft through heat-insulating textolite gaskets 6 to reduce heat transfer between the NVAB and the supporting surface of the spacecraft.
